1. Objectives and Achievements
1.1.
Unit Description
REQUIMTE is the Network of Chemistry and Technology formed by two preexisting research centers, one at University of Porto and the other at New
University of Lisbon. The Network was already fully operational when the
government initiative of “Laboratórios Associados” (LA) was launched. The
status of LA was granted late in 2001, becoming effective in January 1st,
2002.
From the onset, the challenge was to focus the complementary expertise of
the two centers into adopting the tenets of Sustainable Chemistry, and to
bridge the geographical gap between Lisbon and Porto. To accomplish these
goals, REQUIMTE set up a board of directors to reorganize the new large
laboratory into five thematic areas sharing a Green Chemistry perspective
and to allocate funds to promote their implementation. The board relies on
the advice of a scientific and technical commission composed by six senior
researchers from REQUIMTE and up to three external advisors, which
convenes at least eight times a year.
This organization has proved to be efficient, as demonstrated by the growth
of performance indicators, such as number and impact of publications,
financed projects, doctoral students. To further accelerate the interaction of
different research groups, the board of directors:
• defined a global policy of equipment acquisition to address recognized
needs and to assure equal opportunity of access to all equipment for
REQUIMTE’s members;
• created a program to finance seed projects, small research projects that
involve at least two (PhD-holding) researchers from each University, that
led to successful applications to external funding;
• organized five scientific meetings (Porto 99, Caparica 01, Fátima 04,
Fátima 06 and Caparica 08); these events brought together all researchers
in REQUIMTE; sessions included keynotes in Green Chemistry and a forum
to discuss ongoing work.

Finally, a caveat must be made concerning the annual budget of REQUIMTE
– it includes, alongside other funds from national and European agencies,
two main contributions: (a) from FCT [the grant to the Laboratory,
studentships (Ph.D. students), fellowships (post-docs) and the salaries of
the researchers hired under the programs “CIÊNCIA 2007” and “CIÊNCIA
2008”]; and (b) from the two Universities [the salaries of academic (60%)
and technical staff]. However, the costs of infrastructures and maintenance,
supported by the Universities, are not yet included.
1.2.
General Objectives
REQUIMTE, as Laboratory devoted to Green/Sustainable Chemistry, took as
its mission to cooperate in a continuous, competent and efficient mode in
the pursuit of the national scientific and technological policy of REQUIMTE’s
five thematic areas. As mentioned in previous reports, the Laboratory is
now organized in the following five Research Lines:
(a) Novel Compounds from Renewable Sources;
(b) Food Quality and Safety;
(c) Analytical Control and Process Automation;
(d) Clean Chemical Processes;
(e) Chemical Biology and Bioengineering.
(Please note that the names of the Research Lines in FCT on-line forms still
refer to the five Research Lines proposed more than ten years ago.)
The main objectives of REQUIMTE as the Portuguese Associated Laboratory
for Green Chemistry, and a large Network for Chemistry and Technology
are:
(i) to develop knowledge and know how to promote the utilization of green
products and clean technologies to help prevent pollution at the source;
(ii) to transfer technologies to society;
(iii) to train young researchers in interdisciplinary areas related with the
practice of Sustainable Chemistry;
(iv) to answer questions and solve problems raised by government and
society;
2 (v) to promote social awareness for the key role a greener Chemistry will
play in a sustainable world.
Its strategic plan continues to focus the scientific expertise and
complementary knowledge available in REQUIMTE on the topic GREEN
CHEMISTRY – CLEAN TECHNOLOGIES AND PROCESSES, with a wide range
of tools and from different perspectives.
In general terms, the existing competencies will be drawn from the areas
identified as fields of expertise within REQUIMTE: chemistry – analytical,
physical, synthetic; (micro)biology; biochemistry and molecular biology;
molecular modeling; (bio)catalysis and reaction mechanisms; bioconversion
and bioremediation; new solvents and separation processes; sensor
development, monitoring and control. The (inter)relationships between the
Research Lines and areas of expertise (Research Groups) is depicted
graphically
in
the
organigram.
(http://www.requimte.pt/files/1270026203_REQUIMTE_Organigrama_2010.
pdf)
This mix is well suited for a Green Chemistry approach, which always
requires a plethora of perspectives, ranging from scientific to technological
and to economical. Moreover, in a country like Portugal, with a relatively
weak home-based Chemical Industry, interaction with local activities must
be carried out through related areas of interest, such as Food Technology,
Non-Food Agribusiness, Paper and Pulp, Pharmaceuticals, Materials and
Energy Systems.
1.3.
Main Achievements during the year of 2009
REQUIMTE is recognizably a science-driven institution that is already
acknowledged in Portuguese Chemistry and Chemical Engineering as a
leading player in technology transfer, spin-off creation and scientific service
provision.
RESEARCH OUTPUT IN 2009:
358 articles were published in peer review journals;22 PhD Theses and 120

2. Activities
2.1. Integrative/multidisciplinary activities during the year of
2009
The year of 2009 will always be recognized at REQUIMTE as the year of the
first edition of the Doctoral Program in Sustainable Chemistry. In fact, the
launch and organization of this PhD program focused on the thematic area
4 of the Associated Laboratory, was a significant effort of the majority of
laboratory members and led to numerous discussions that contributed not
only to the organization of the program but also to the establishment of
new collaborations among the various research groups. The PhD program
includes four “Schools” in which the students get together during a week
either in Porto or in Lisbon and discuss themes such as Green Chemistry
and Entrepreneurship. Two of these schools have an international character,
counting with the collaboration of academics and industry professionals
from other countries, and are open to foreign students and students from
other national programs.
The consortium between REQUIMTE, CICECO and LSRE-LCM, three
Associate Laboratories whose area of activity is focused on “Molecules,
Materials, Processes and Products”, M2P2, was established and will cultivate
the sharing of equipment, doctoral programs and transdisciplinar projects .
By drawing on different research cultures and sharing good practices of
research and of technology transfer, the new consortium is expected to
enhance the performance of the individual LAs and to allow a more
competitive role in the European Research Area. In the framework of the
M2P2, REQUIMTE will be able to raise the profile of Sustainable Chemistry
activities, with impacts at the level of industry and chemical-related services
and public awareness of Science.
REQUIMTE researchers participated in the meeting “Ciência 2009 - Encontro
com a Ciência em Portugal” sponsored by the Associate Laboratories and
the Ministry of Science, Technology and Higher Education and delivered the
oral presentations:
-Intelligent particles for controlled release (Ana Aguiar Ricardo)
-Molecular modelling in life sciences (Nuno Cerqueira)
-Resulting contaminants from the thermal processing of food (Isabel
Ferreira)
-“Systems biology” for vaccines, the example of Rotovarius-like-particles
(Rui Oliveira)
-Production through “microbial via” of biopolymers from glycerol, a subproduct of the biodiesel industry (Maria Ascensão Reis).
5 2.2 Outreach activities during the year of 2009
REQUIMTE has been an enthusiastic participant in activities related to the
public awareness of Science, stressing current concerns of Green Chemistry.
Researchers participate in all activities organized by national bodies and by
the universities, targeting primary and secondary school students, school
teachers and the general public. Furthermore, REQUIMTE researchers
actively participate in brokerage events, where they become aware of
industry needs and have the opportunity of establishing collaborations with
industry partners.
REQUIMTE continues its involvement with the project Casa das Ciências
(started in 2008, with an annual funding of 100 k€ by Fundação Calouste
Gulbenkian , http://www.casadasciencias.org) which is creating a repository
of open education resources with the aiming to improve Science teaching in
schools.
REQUIMTE maintains its annual participation in many initiatives organized
by the Universities, such as “Expo FCT”, “Chemistry Days”, “Mostra da
Universidade do Porto” and “Universidade Junior” attracting many hundreds
of secondary school students and their teachers, who come to attend
lectures, watch exhibits, and participate in experiments and lab tours.
REQUIMTE participates regularly in events organized by “CIÊNCIA VIVA”
(the Portuguese Agency for Public Awareness of Science), such as “Science
and Technology Week”, “Fórum Ciência Viva” and programs to integrate
young high school students in research laboratories during summer
vacations.
REQUIMTE members participate yearly in the organization of “Olimpíadas da
Química”, a competition addressed to high school students.
Club Math is an event organized by the Mathematics Department and during
the event high school students visit the Requimte and participate in
activities.
The “European Researchers Night” initiative counted in 2009 with the
participation of REQUIMTE researchers. This initiative offers society the
unique opportunity to get together with researchers and their world.
REQUIMTE projects have been presented at several instances in the national
TV programs devoted to science, namely “Ciência 2010”. A new initiative
will lead to a short TV serial on the public understanding of science.
6 Using its expertise, REQUIMTE organizes regularly monographic courses
open to academic and industrial researchers. Detailed information in
http://www.requimte.pt/index.php?section=31.
REQUIMTE participated in Brokerage Events such as the 4th Innovation
Days (organized by the national Agency for Innovation) where researchers
showed its R&D project results to the industry.
The REQUIMTE member Paulina Mata published (as co-author) the
educational book “A cozinha é um laboratório” (The kitchen as a laboratory)
and participated in several events to promote science to the general public.

10 4.4 Additional Comments:
We would like to stress that in the 2009 Report, and for the first time, we
are including in the total budget, under “Funding- Other(National)” a
contribution of the Universities to the running of the Associate Laboratory.
As only the salaries of the academic and technical staff are included, it is
not a “total cost” approach yet.
A figure of ca. 6,4 M€ is obtained for this contribution, with the assumption
that 60% of the salaries are associated with efforts put into activities of
REQUIMTE.
In the table, for previous years, under “Funding- Other(National)” the
values included only salaries of IAs (Ciência), scholarships (Ph.D. students),
fellowships (post-doctoral fellows) and projects of other national agencies.
For comparison, the value for 2009, excluding staff salaries, would be 3 920
286,88 €.
When the Universities are in a position to provide an auditable cost for the
infrastructures, maintenance and operation, these values will also be
included.
On another matter, the Associated Laboratory aimed in 2001 the hiring of
30 Auxiliary Researchers and has established contracts with 28 individuals
until 31rst December 2008. During the year of 2009 the positions were
advertised, the selection process has been completed during the year of
2009 and at its end the 30 positions have been filled.
5. Research Groups
11 5.1 Organic Chemistry
5.1.1 Group Description:
Research Group Title: (RG-LVT-Almada-750006-3286) - Organic Chemistry
Principal Investigator: Ana Maria Félix Trindade Lobo
Research Area: Chemistry
Home Institution: Faculdade de Ciências e Tecnologia - Universidade Nova
de Lisboa
5.1.1.1 Funding, source, dates
The financial support obtained in 2009 can be divided in two parts: the
institutional support, and external funding. The institutional support
included: (1) salaries of University teaching staff and infrastructure
maintenance - 494 k€; (2) salaries of researchers hired by REQUIMTE, and
provided by the funding agency (Fundação para a Ciência e a Tecnologia) 384 k€; (3) fellowships for PhD students and Post-Docs, mainly obtained
through competitive FC&T calls - 343 k€ (4) Institutional funding for generic
research (FCT Base, provided by “Fundação para a Ciência e a Tecnologia,
FCT/MCTES according to 2008’s research team) per PhD with a merit based
criteria - 159 k€.
Support from external sources, was mainly obtained through projects
submitted to competitive calls, at national and international level, or from
industry. During 2009, this group had ca. 170 k€ funding through 8
externally funded projects. The largest slice of the budget was obtained
from projects won in competitive calls of FC&T, which raised ca. 167 k€ (98
% of total) for science-driven research.
5.1.2 Objectives and Achievements:
5.1.2.1 Objectives
Throughout the period under review, the OC area included 13 University
teaching staff, 7 assistant researchers, 8 Post-Doc fellows, 12 PhD students,
20 juniors students. The postdoctoral researchers were from different
nationalities (Portuguese, Indian, Ucranian, Servian, Bulgarian) and a
12 variety of trainees from different European and North Africa countries, as
well as Brasil and Cuba, also worked at different intervals.
Through the year of 2009, this RG retained a strong motivation to innovate,
to remain competitive in a landscape of shrinking funds and to foster links
with other diverse research groups both within and outside REQUIMTE’s
laboratories going well beyond the frontiers of chemistry.
From a formal scientific discipline angle its interests encompass the areas of
organic synthesis, mechanisms of reactions of practical importance, natural
products structure, biosynthesis and metabolism, computer applications in
chemistry, namely molecular modelling and chemoinformatics, and
molecular gastronomy.
Its main objectives include:
a) to discover new chemical reactions, specially those where chirality is
efficiently induced, using the green chemistry paradigm, with application in
the synthesis of novel natural products, metabolites or chemical structures
of practical interest in pharmaceutical, environmental, agrochemical, flavour
and fragrance industries and related activities;
b) to clarify the mechanisms of reactions of practical importance with a
special focus on those involving radical species during in vivo metabolism;
c) to discover new natural products of practical importance, clarify their
structure and biointeractions;
d to enhance the economic value of easily accessible natural products
through hemisynthesis and as raw materials;
d) to develop new tools of computing for molecular modelling, mapping
chemical reactions, mechanisms, compounds properties, and in mining,
expanding and curing databases;
e) to extend and adapt existing tools for teaching chemistry using the web
so as to facilitate learning including by blind students;
f) to provide a platform to train undergraduates, MSc and PhD students
through research activities;
g) to use the web to enhance the scientific literacy of chemistry university
students as well as the general public (as with the ongoing pandemic due to
the H1N1 virus).
13 5.1.2.2 Main Achievements
Synthesis & Hemisynthesis
Chiral ionic liquids were synthesized from isommanide and isosorbide and
used to coat capillary to be used in enantio GC chromatography. These CILs
were obtained by a carbohydrate moiety holding immidazolium,
tetraalkylammonium or piridinium salts, as cation counterpart, and tosylate,
trifluoracetate, triflate, bis(trifluormethylsulfonyl)imide as anions.
Key functional groups at different positions of the indole nucleus were
evaluated, and the optimized structures were next prepared for subsequent
COX inhibition evaluation. A library of promising indole based compounds
was prepared using novel synthetic methodologies.
The rational design of novel antioxidant compounds also led to the
investigation of the radical scavenging potency of a small library of novel
tryptophan and tryptamine synthetic derivatives, by evaluating their in vitro
scavenging
activity for hypochlorous acid (HOCl) and peroxyl radical. These radical
oxygen species (ROS) were chosen due to its hitherto relatively unexplored
reactivity with indole derivatives. The obtained results revealed a promising
antioxidant activity against HOCl and peroxyl radical for the novel
synthesized compounds.These results are now being used for the design
and development of new antioxidant drugs.
A new clomiphene metabolite, extremely useful for doping analysis, was
synthesized in 19% overall yield. The
approach involved a Grignard reaction via a N-acylbenzotriazole
intermediate to afford a key aromatic ketone, and an HWE reaction. Both
stereoisomers were separated and identified.
The use of iron complexes to oxidize hydrocarbon compounds, alkanes and
alkenes are known reactions. If chiral ligands are used a stereoselective
oxidation can be achieved. The synthesis of chiral ligands derived from
chiral prolinamides and prolinamines was accomplished with coordination
with Fe(II) and Fe(III) observed.
14 Tandem aziridination-homologation reaction of N-sulfonylimines were
achieved with a very simple, rapid and mild procedure through the use of
diazomethane.
A synthetic PGN derivative, precursor of a biologically active PGN, known to
be involved in the cellular recognition, was prepared by SPS. The synthesis
involved the preparation of a N-troc glucosamine moiety and of a simple
amino acid sequence. The last step consisted in the coupling, on solidphase, of the protected muramyl unit to the peptide chain.
Two valuable procedures in glucosamine chemistry were developed: the
regioselective one-pot protection of glucosamine and the isomerization of
the anomeric allyl group using Et3SiH and Pd(PPh3)4. Glucosamine
regioselective one-pot protection allows a straightforward synthesis,
skipping the time consuming work-up and purification steps, while the new
method for allyl isomerization prevents the use of the costly metal
complexes.
HR-MAS NMR spectra of the solid-phase synthesis support, Sieber amide
resin, were reported for the first time.
High-pressure NMR techniques were performed in order to obtain
information on the molecular structure and dynamics of TA-β-CD in scCO2.
Natural Products
Anti-inflammatory and anti-neoplastic properties were searched in Solanum
and Cissus genus. A derivative of dopamine and a guanidine compound
were identified from the ethanol extract of Solanum together with
quercitrine, afzelin, hyperin and caffeic acid.
Mechanisms
The first examples of RT N-oxi-3-aza Cope rearrangements were reported
and found to be dependent upon the configuration of the rearranging
system double bond.
Chemoinformatics & Computer Modelling
Work in this area involved: a) QSAR of tuberculostatics; b) development of
Random Forest models for the prediction of reactions of different
compounds from a database of chemical reactions; c) chemometric studies
for the classification of samples of crude oil, wines and urban soils.
The design of novel COX-2 inhibitors involved a molecular docking
methodology which was applied to several tryptophan and indomethacin
derivatives, in a total of 58 compounds, based on the generation of grid
15 maps of electrostatic potential for different atom probes. For both groups of
compounds, the results led to the identification of possible binding modes
and important interactions on the COX-2 catalytic domain and to suggest
future modifications on the indole ring in order to improve the affinity for
the enzyme.
A new proposal, which explains the observed stereochemistry, both in DielsAlder and in electrophilic additions to alkenes, was presented.
Molecular Gastronomy research, distinguished by a strong innovation and
internationalisation, launched its first postgraduate course in the Faculty.
Chemistry teaching was reinforced with a national interest from secondary
schools in the published materials, specially the book ‘The Kitchen is a
Laboratory’.

5.1.2.4 Future Research
5.1.2.4.1. Objectives
Interdisciplinarity will be maintained and a strong inter-laboratory
collaboration will be actively encouraged both with other Portuguese
Laboratories as well as new foreign ones (USA, Brasil, Denmark). Thus
organic synthesis type issues associated with natural fresh-water
management (a major problem in the future), pollution control and
biomarkers for major pathologies will be actively continued, along those
associated with the industrial needs to use easily accessible natural
products in new industrial applications. Simultaneously computer
applications in chemistry will be developed in reply to perceived practical
needs in inter alia pollution and cosmetics, including skin sensitization.
Synthesis
A strong interest in the synthesis and evaluation of biologically active
compounds with chirality is retained by the research group, involving either
the development of a library of chiral hemilabile ligands for transition metal
homogeneous catalysts or organocatalysts and its use in water or
biocompatible solvents.
Novel developments in ‘green’ type synthesis will be sought such as those
relating to heteroatom containing systems susceptible to electrocyclic
rearrangements, specially 3-aza-cope systems, by devising low temperature
rearrangements.
The need for new synthetic methods that produce important intermediates,
such as aziridines, will be continued and its use for polymers developed.
28 It is intend to use the new CILs carbohydrate-based as chiral stationary
phases in capillary columns to identify and quantify the enantiomers of
natural ou synthetic chiral compounds in complex mixtures. The adequate
strategy will be improved by the study and optimization of appropriate
chemical transformation in model compounds.
Functionalized chiral epoxyphosphonates will be further used for the
synthesis of of antibiotics, fungicides and antiviral.
Sarting material natural arbohydrates will be reagents in a Mitsunobu type
reaction for obtention of hydrophilic and water solube polymers. These can
be used for drug delivery systems, dental medicine, bio implants and tissue
engineering.
Asymmetric additions to alkenes, by using chiral N-acyloxazolidinones and
N-acylimidazolidinones will be completed.
Ligand specificity in cellulosomal carbohydrate binding modules will
continue, and the binding epitotes of CtCBM44 will determined and
compared with those for CtCBM11.
NMR methodology, based on NOE and PFG, will support the study of
intermolecular interactions in scCO2, including solvent properties of ionic
liquids.
Natural products and applications
The search for new natural product structures with pharmacological activity
(anti-cancer, anti-inflammatory, anti-TB) will be continued in a collaborative
international effort, involving for example Angola and Mozambique. A new
partnership with an American university will be set up for bioactive natural
products search from Atlantic deep seabed bacteria.
Mechanisms
Radical intermediates, generated by radiolysis in aqueous and nonaqueous
solutions, will help the elucidation of oxidative stress mechanisms, in radical
polymerisation and in the disinfection of dewatered sewage sludge, specially
in the case of biorecalcitrant compounds. The use of Pulse Radiolysis, which
will be operating for the first time in Portugal, will result in a powerful
impetus in the characterization of new antioxidants, through the
establishment of new reaction pathways with oxidizing radicals.
Chimioinformatics & Computer Modelling
The work at the interface between chemistry and computers will be pursued
with application of Chimioinformatics and Chimiometrics for the prediction
29 of biological activity (anti-TB) and toxicity (reactivity with peptides) of
compounds based on their molecular structure. Novel physicochemical
descriptors of bonds and atoms will be calculated by semiempirical
methods.
QSAR prediction of the anomeric configuration in disaccharides using NMR
data will be actively pursue.
Mechanistic aspects of asymmetric aldol reactions will be studied in silico in
order to clarify the full mechanism of the process.
Theoretical work aiming at the rationalisation of chiral auxiliary based free
radical mechanisms, with or without Lewis acid catalysis, will be completed.
Molecular Gastronomy
This new area, which has grown in importance countrywide, will be
responsible for the introduction of a new MSc degree in the near future in
the Universidade Nova de Lisboa. The new group has started its
experimental research in the premises of the university.
Science teaching
The work in science (chemistry) teaching to the general public will be
continued through the on-going national and international partnerships, the
use of the media (TV and radio), as well as the public press. Simultaneously
partnerships are being sought for translation into english/french and
production of some of the material published in Portuguese.
Development of open web pages in English to teach blind students
chemistry (organic) will continue well into 2010, and plans to adapt such
work to the Portuguese language have started.
5.1.2.4.2. Funding, source, dates
Projects’ approved financing for the period 2008-2011 amounts to ca. 1010
K€, of which 300 K€ are pending decision. Other sources of financing of
Portuguese origin are not expected to exceed 15% of the total funds. An
aggressive international fund raising initiative was developed but the
financial and economic crisis has had a deep impact in the country and
elsewhere with the resulting slowdown of scientific investment.

5.2.2 Objectives and Achievements
5.2.2.1 Objectives
The C&BE Group reinforced their record on membrane processes,
supercritical CO2 (scCO2), bioremediation, porous materials, and catalysis
and adsorption. The development of Clean Technologies & Sustainable
Processes in Chemical Engineering is a clear priority of REQUIMTE and thus
of C&BE Group. The 2009 publications are evidence for the specific efforts
32 towards the development of Materials for Sustainable Processes (M4SP),
and a broader coverage of the core fields of Reaction & Separation Media
(R&SM) and Process Design & Engineering (PD&E).
M4SP includes biosynthesis of biodegradable polymers, the development of
extraction and purification processes of biopolymers; stimuli-responsive
bioactive hydrogels synthesized in scCO2, development of new stimuli
responsive devices for drug delivery and tissue engineering. R&SM focus on
synthesis and tailoring of catalysts for conversion of gaseous pollutants; on
the development of polymeric catalytic membranes & heterogeneous
catalysts applied to production of biodiesel and fine chemistry reactions
(hydration & oxidation of terpenic olefins and transesterification of soybean
oil over hydrotalcites, the use of ionic liquids for cellulose and glucose
hydration); removal of xenobiotics from waste water through biological
processes. scCO2 and the development of scCO2-assisted processes are a
key topic. In particular, new green processes for valorization of wastes from
the coffee industry are being implemented within a Portuguese Industry
contract research. Biocatalysis in non-aqueous solvents for green chemistry
& processing are intensively studied. Membranes area is also a key topic
(membrane bioreactors for removal of charged pollutants from drinking
water supplies; nanofiltration of valuable compounds; membrane extraction
of bioproducts using selective carriers and supported ILs), the development
of protein purification schemes based on novel chromatographic, magnetic
and membrane affinity separations. Modeling and optimization are
increasingly applied to scCO2 extraction and filtration processes, SMB
chromatography and gas separation, sorption studies on open-ended carbon
nanotubes (CNTs), to develop hybrid processes for separation of
gaseous/liquid mixtures from feed streams such as aromatic/aliphatic,
biogas and gaseous effluents of chemical and petrochemical industries,
optimization of animal cells/viral-vector systems for the vaccine production
and gene therapy. The Process Design & Engineering activities took
advantage of the resulting critical mass allowed by collaboration between
different research groups, and newly established industrial collaborations.
A 2nd objective of the C&BE group is to increase the collaboration in
common projects; this is being clearly attained, yielding many joint
publications by different group members and external collaborators. A 3rd
objective is to bring new perspectives and bridge gaps between R&D units,
through the new contracted researchers. Overall, the fulfillment of these
objectives has contributed positively to C&BE Group’s collective goal of
demonstrating scientific excellence and international recognition.
Peer recognition indicators of the Research Group quality in 2009 were:
55 papers in peer review Journals (one was the cover of Green Chemistry
journal); 6 PhD thesis accomplished; two best poster presentations were
awarded in International Conferences.
Very diverse scientific achievements, may be cited:
New “green” strategies were developed either to synthesize or to process
synthetic and natural polymers. Molecularly imprinted polymers (MIPs) with
high specificity towards an enantiomeric molecule were synthesized in
scCO2. The polymeric materials were tested as stationary HPLC phases
showing chiral recognition capability. The effect of nano-confinement in
zeolites (pore sizes from 2.8 to 6.8 nm) on the molecular dynamics of a LC
was evaluated: simultaneous detection of two surface processes due to
molecules adsorbed outer and inner the confining surfaces of nanopores;
detection of glassy dynamics in LC molecules anchored to the inner surface
revealing pore size dependence. Catalyzed hydrogenation reactions of
terpenes in mono- and bi-phasic conditions in high-pressure carbon dioxide
were studied and the conditions that maximized the product selectivity were
determined. Novel processes were designed and optimized to prepare hightech porous structures, namely stimuli-responsive membranes and chitosan
scaffolds without any solvent residues and with new biocompatible crosslinkers. Also, the creation of new magnetic nano and micro structures for
the affinity purification of biomolecules, and the development of new HTS
techniques for the selection of affinity ligands for important target proteins
was successfully achieved. Cellulose affinity membranes were prepared for
the first time using a green solvent (IL) for antibody purification. Activated
carbon obtained from peach stones and sisal were prepared and used as
adsorbents to remove pharmaceutical pollutants. (Cs)Al-SBA-15 or
DEAPTS/MCM-41, with very different textural properties and composition,
were found to be efficient catalysts for the pyrazole alkylation with different
reactive alkyl bromides under thermal activation. They constitute the first
examples of modified molecular sieves catalyzing these reactions. Novel gas
separation processes, coupling pressure swing adsorption (PSA) and
simulating moving bed (SMB) technologies are being studied. Cryogenic
adsorption of nitrogen, hydrogen and light hydrocarbons on several
activated carbons and MIL-53 (Al) metal-organic framework (MOF) are
undergoing in collaboration with the Physic’s Department of FCT/UNL.
Hybrid modelling techniques for Systems Biology. Biotechnology and
Bioprocessing were implemented. The real-time monitoring of mammalian
cultures as well as PHA producing cultures was performed through a
combination of respirometric, titrimetric and chemometric techniques. On-
34 line metabolic flux analysis was successfully applied to PHA producing
systems.
55 papers were published by C&BE group researchers in 2009. These
papers show a strong collaboration with other Portuguese Assoc Lab, and an
increase in the average impact factor comparing with previous years. Mostly
were published in journals with a high impact factor in the areas of
Chemical or Environmental Engineering . 17 papers were either published in
5 of the ten highest ranked (by impact factor 2008) journals in Chemical
Engineering or in 5 of highest ranked journals in Environmental Eng (1 in

A significant number of joint publications, resulting from collaborative
research with other research groups and laboratories, have been produced
(see list of publications). Also, two bilateral exchange projects between
Portugal and Spain were funded through funding agencies and Universities.
There were 4 internationally funded projects by European Commission
(NanoMemPro ; EUROMBRA; OPTIM’OILS; two ERA-Chemistry projects).
The participation in the Network of Excellence (NoE) on Nanoscale-based
Membrane Technologies, “NanoMemPro” (NMP- CT-2004-500623) lead to
the creation of a legal entity (the European Membrane House) to foster
industrial collaborative research, and the creation of two international high
education programmes, an Erasmus Mundus Master and an Erasmus
Mundus Doctorate on Membrane Science and Technology.
One Individual Marie Curie Fellowships was obtained (FP7-PEOPLE-2007-22-ERG / PERG02-GA-2007-224930).
REQUIMTE is actively participating in the MIT-Portugal Programme. The key
area of Bioengineering Systems (BIO-E) is coordinated by an investigator of
C&BE and other 8 C&BE researchers are involved in the educational
programs of BIO-E: i) lecturing in the Advanced Studies one-year Course
and ii) supervising joint PhD students with MIT.
Researchers from C&BE have been participating as invited lecturers, as
members Scientific committees of International conferences (e.g., the
Summer School of the European Membrane Society; 5th Pacific Basin
Conference on Adsorption Science and Technology; ), in Masters and PhD
programmes in Europe (e.g., at the University of Calabria, Italy and the
University of Cantabria, Spain). Also, belong to the editorial boards of
42 scientific journals (e.g, M A Reis is editor of Water Research). M Nunes da
Ponte was, from July 2008 to June 2009, Chairman of the High Level Group
of EUREKA, the pan-European Network for applied research.
The research to be pursued in the following two years period is driven by
the research programs contracts already established with external funding
agencies and newly established industrial collaborations. C&BE researchers
has a strong commitment towards the development of:
•Different hydrogel-based smart small scale systems (i) for in vivo drug
delivery (smart microporous particles); (ii) for ex vivo cell expansion (3D
matrices or scaffolds); and (iii) for monitorization of cell environment
(bioactive beads). A high level board, consisting of academic groups from
different institutions (Portugal- REQUIMTE/UNL and IBB/IST; EUA - MIT, an
hospital (IPOFG) and two companies (ECBio and Hovione), is committed to
achieve the objectives defined in the project plan.
•Nanoporous confinements to stabilize less stable forms of pharmaceutical
drugs and as a mean to avoid crystallization in different low molecular
weight materials.
•Novel polyurea dendrimers for drug delivery and sensing applications. Part
of the work (biocompatibility, biodistribution and drug delivery using LBL)
will be performed at MIT in 2010 in collaboration with Prof. Paula
Hammond.
•Integrated biodiesel refineries: transformation of crude glycerol by-product
into value-added polysaccharides; production of efficient biocatalysts and
bioprocesses for succinic acid production and building blocks; production of
polyhydroxyalkanotaes from industrial by-products; symbiotic approach for
sustainable use of microalgae biomass for production of biofuels and added
value bioactive products.
•Processes for biodiesel production: preparation of polymeric materials with
catalytic activity; use of magnetic iron oxide nanoparticles combined with
supercritical carbon dioxide in the fractionation of oil mixtures and recovery
of added-value substances, coupled with biocatalysis.
43 • Valorisation of sub-products of agro-chemical industries: aroma recovery,
high value chemicals from the oil industry, bioactive molecules from waste
materials of the coffee industry.
•Water and wastewater treatment processes: Metabolic modelling of
enhanced biological phosphorus removal systems; removal of xenobiotic
micropollutants from wastewater; Use of membrane bioreactors for removal
of micropollutants; Understanding of process of biofouling of membrane
bioreactors; Systems Biology and Bioinformatics Modelling; Monitoring and
Optimisation of Bioprocesses (e.g. using 2D fluorescence, chemometrics);

The financial support obtained in future years will presumably continue to
be divided in two parts: the institutional support, and external funding. The
institutional support will include: (1) salaries of University teaching staff and
infrastructure maintenance, provided by the University; (2) salaries of
researchers hired by REQUIMTE, and provided by the funding agency
(Fundação para a Ciência e a Tecnologia); (3) fellowships for PhD students
and Post-Docs, mainly obtained through competitive FC&T calls, but also
from EU support programs; (4) Institutional funding for generic research

than 30 externally funded projects. The largest slice of the budget was
obtained from projects won in competitive calls of FC&T, which raised ca.
498 k€ (73 % of total) for science-driven research. Projects won in Euripean
Comission Framework Programmes contributed with 134 k€ (20% of total)
5.3.2.1 Objectives
The research group is constituted by 46 senior researchers (of which 20 are
hires Auxiliary Researchers), 15 postdoctoral fellows, 42 PhD students and
45 other students. The research group is organized in different research
laboratories, headed by senior researchers, with complementary expertise.
Having competencies in biochemistry and biophysics, the research
laboratories have know-how in several other scientific areas such as (but
not restricted to) molecular biology, microbiology, bioinorganic chemistry,
45 computational chemistry, crystallography and spectroscopy. Such
knowledge is well suited for the pursued objectives, which are often of a
multidisciplinary nature, and make the research group able to contribute to
several research lines of RequiMte.
Studying the role of metal ions in biology has been a long-standing
objective. In the last year focus was maintained in the structural and
functional characterization of metalloenzimes systems, metal ion
metabolism, toxicity, metal resistance and metallodrugs. Mostly targeted
were enzymes participating on nitrogen and sulfur cycle, with one important
point being the study of molybdopterin-containing enzymes (nitrate
reductases and aldehyde oxidases). Efforts have been done in the structural
and functional characterization of key proteins in the electron transfer
chains of Geobacter sulfurreducens, a bacterium involved in the
bioremediation of toxic/radioactive metals and electricity production. In this
case, probing the signal-transduction mechanisms in a new protein sensor
family from G. sulfurreducens containing periplasmic c-type heme domains
is also an objective.
A strong emphasis was put on structural studies of bacterial xanthine
oxidase chaperones and Moco binding proteins, heme-binding proteins,
human wt and mutants of phenylalanine hydroxylase (molecular
determinants of phenylketonuria) and xenobiotic reductases and type II
hydride transferases involved in TNT aromatic ring reduction.
Other rather challenging and complex problems under study are the
structural characterization of mRNA localization mechanisms (two of the
proteins involved in the process are being studied : Yps and Exu) and the
Cellulossome. Studies on new components of the Cellulosome assembly
were done, and Cryo-EM techniques were introduced in an attempt to gain
further insights into its 3D structure. Studies on the characterization of
several Carbohydrate Binding Modules are being pursued. Also, in 2009 we
became interested in the development of carbohydrate microarrays and its
application to carbohydrate ligand discovery for different biological systems.
Understanding mechanisms at biological membranes level is a well
established objective and usually focused in medical and pharmaceutical
challenges. In this case transport mechanisms, drug-membrane interactions
and membrane structure and integrity are being study. Many objectives
were pursued such as:
- PLA2 inhibition by Non Steroidal Anti-inflammatory Drugs (NSAIDs), its
antioxidant properties and capability of modulating membrane structural
properties;
46 - Water transport in yeast and plant aquaporins expressed in S. cerevisiae
yeast cells;
- Study of glycerol permeation in adipose tissue cell membranes and its
involvement in obesity;
- Effects of nutraceuticals

membrane
- Study of water and solute transport in Babesia bovis infected erithrocytes;
- Biophysics of Proton Balances;
- Use of patch‐clamp studies to unveil membrane transporters involved in
pollen tube growth, renal sensors for diuretics, hormones and ionic control.
We were also interests in the characterization of the influx mechanism of
fluoroquinolones, cephalosporins and fluoroquinolone metalloantibiotics
through porins OmpF and OmpC reconstituted in E.coli model membranes,
by different biophysical techniques, to understand the uptake mechanism of
these compounds in order to try to counteract bacteria resistance.
In addition, it is in our objectives to explore molecular modeling in order to
understand enzyme mechanisms, help in drug design, interpretation of the
color in naturally-occurring pigments at a molecular level and produce
mathematical models that can be applied in several biomolecular systems,
in particular those involving biochemical reactions.
We became increasingly active in the area of bionanotechnology, meaning
the use of nanotechnological devices for applications in biotechnology.
Particularly interesting has been the development of such devices in clinical
and diagnosis applications and trying to understand the interaction of
nanoparticles with cultured cell lines.
5.3.2.2 Main Achievements
In 2009 the group published more than 50 publications in peer review

5.3.2.3.6. Government/Organization contract research
Members of the research group have participate in different activities,
namely review boards and evaluation panels. In 2009 there was the
participation on the Chemistry panel for research fellowships as well as a
participation, at request of Deutsche Forschungsgemeinschaft (DFG), on the
evaluation board of a research unit from Technische Universität
Braunschweig (M.J. Romão).
63 5.3.2.4 Future Research
Research on biologic use of metal ions and metalloproteins will continue,
and identification of the molecular mechanisms developed by Desulfovibrio
and Marinobacter genus to adapt to changes in environmental conditions
with special focus in the metabolic pathways regulated by metal stress (Mo,
Cu, As) will be performed. Because denitrification is a main research topic,
time will be devoted to the biochemical, spectroscopic, electrochemical and
crystallographic studies of the least characterized enzyme of this metabolic
pathway. We will attempt to characterize three different redox states of this
enzyme. Other metalloproteins will be under scrutiny. We will try to study
the effect of the culture supplementation with W and Mo on formate
dehydrogenase production and perform structural characterization of its
active site using EPR advanced techniques. Other studies will aim:
- Heterologous expression of matrix metalloproteinases (MMPs) and
evaluation of molecular interactions with synthetic inhibitors using NMR
spectroscopy.
- Study of the respirome of Desulfovibrio desulfuricans ATCC 27774.
- Determination of structural, kinetic and spectroscopic properties of
mononuclear Mo-enzymes purified from bacterial sources aid to understand
the catalytic mechanism of these enzymes.
- Structural and functional studies on Mo-dependent enzymes. The systems
under study will be CnNapAB, DgAOR, DgFdh and mouse AOH1. In addition
we will continue studies on Moco-binding proteins as well as on hemebinding proteins.
-Structural, biochemical and functional characterization of proteins with
heterometalic centers involved in stress response.
- Structural and kinetic characterization of bacterial enzymes involved in
iron metabolism and ROS detoxification.
- Structural and Functional Studies on NO synthase complexed to
radiolabeled compounds (Molecular Imaging probes).
- Understand and optimize the electron transfer pathways in G.
sulfurreducens cells, which mediate the bioremediation of toxic/radioactive
metals and electricity production.
64 Another enzymatic system that caught our attention on recent years is the
cellulossome. We will continue Cryo-EM studies of the Cellulosome to
determine parts of its 3D structure at low/medium resolution. High
resolution characterization of several modules, isolated or in complex, will
be achieved by X-ray crystallography. We aim to establish the carbohydrate
microarray technology and introduce it to the study of biological systems
that involve carbohydrate recognition, in particular novel CBMs of bacterial
cellulosomes. The high throughput features of the carbohydrate microarray
technology will be combined with X-ray crystallography to derive structural
information at the molecular and atomic levels.
Also, the continuation of the structural studies of wt and chimeric forms of
stabilized human PAH, towards the understanding of the molecular
mechanisms of phenylketonuria will be performed.
We will maintain the industry collaborative effort to study
releasing molecules (CORM) with typical serum proteins
level. We intend to determine the 3-D structures (wt and
II hydride transferases and closely related nitroreductases
Enzyme family.
interaction of CO
at the molecular
mutants) of type
of the Old Yellow
Of great interest are the studies Non Steroidal Anti-inflammatory Drugs
(NSAIDs) in biomembrane model systems, with interaction, location and
antioxidante capacity studies. We focus, not only in the influence of the
chemical structure of antioxidants, but also the nature of the interactions
between these molecules and membranes. Other antioxidants and/or antiinflammatory species will continue to be studied (namely of 2styrylchromones and Hypericum androsaemum and Eucalyptus globulus
Labill extracts).
Membrane systems and transport studies will be pursued at several levels.
For example we are committed to the assessment of:
- biophysical changes in cell membranes induced by nutraceuticals
consumption in animal models;
- permeability changes in bovine RBCs caused by Babesia bovis infection;
- Vitis Vinifera aquaporins function and regulation and heterologous
expression of mammalian aquaporins in yeast and biophysical
characterization of transport;
It will also be important to proceed to the characterization of adipocyte
glycerol channel kinetics and screen for putative modulators and to the use
of patch‐clamp studies to unveil membrane transporters involved in pollen
tube growth, renal sensors for diuretics, hormones and ionic control.
65 From the theoretical point of view we will continue to use molecular
simulations and quantum mechanics techniques, as well as quantum
mechanics/molecular
mechanics
or
quantum
mechanics/quantum
mechanics hybrid methods. Docking techniques as well as homology
modeling procedures and computational genomics are an important part of
the studies being done. Expanding the area of Computational genomics is
an important goal. Also, we will follow up on the application of mathematical
dynamic models to different biologic systems, for example trying to model
calcium homeostasis in chronic kidney disease will.
The research group also makes every effort to bridge fundamental and
applied research. If the former lays the foundations to a solid common
ground, the later enable us to pursue some of the objectives stated in
Requimte’s research lines. As an example we hope to develop new catalytic
amperometric biosensors as well as novel electrode interfaces, based on
self-assembled mono-layers and nano structures, and nanotechnology- and
(DNA- or antibodies-) based sensors, for the development of point-of-care
diagnostics. Also interesting will be the use of nanoparticle functionalized
textiles in electromagnetic radiation shielding, or the use of nanoparticles
with cultured cell lines.
Centered in the structural-functional aspects of several complex biologic
systems, the research planned makes use of a wide range of techniques
from the areas of molecular biology, biochemistry, crystallography,
spectroscopy (visible, florescence, NMR, EPR, Mössbauer), rapid kinetics
(stopped-flow and rapid-freeze quench), electrochemistry, computational
chemistry/bioinformatics, just to name a few. Much has been done in the
recent years to improve our research facilities in order to accommodate all
these techniques. However, more has to be done to accomplish future
objectives. It is thus expected to improve on equipment and collaborative
work to enable further progress in:
- high-field and pulsed EPR, ENDOR, and ESEEM;
- EXAFS;
- high-field Mössbauer;
- AFM, SEM/EDS, XPS;
- Single particle Cryo-electron microscopy;
- EQCM/QCM;
- SAXS;
66 - ITC;
- DLS;
- DIGE-based proteomics.
Also, production of macromolecules under study should be improved and
the in house availability of large volume fermentation as well as techniques
for protein expression in eukaryotic systems would be valuable.

5.4.2.1 Objectives
Activities taken in 2009 by analytical chemistry group followed described
trends in previous reports therein subdivided in three main research areas,
either with autonomous development or in order to answer to specific
requests of other REQUIMTE research groups. In them it was generally
aimed: i) the application of new analytical tools to products or complex
samples characterization, ii) the development of new analytical procedures,
sensors and new markers with application to biological characterization,
pharmaceuticals production processes and environmental monitoring. iii)
the proposal of new fast and reliable automatic procedures for the
69 proteomic field, to biological/pharmaceutical control and to food and
beverages analysis. Hence, main objectives of first area for 2009 were the
evaluation of chromatographic techniques particularly based on GC/FID,
GC/qMS, GC/TOFMS, GCxGC/TOFMS, as well as matrix-assisted laser
desorption/ionisation (MALDI-TOF-MS) on the proposal of accurate, less
time consuming, more efficient and reliable analytical methods for organic
compounds. As secondary objective it was accomplished parallel
exploitation of effective sample preparation based on liquid-liquid extraction
(LLE), solid phase extraction (SPE), solid phase micro-extraction (SPME)
and ultrasound assisted digestion in order to simplify sample pretreatments.
It was aimed its usefulness at biological level as diagnostic predicting tools
and in authenticity studies related with Portugese food products.
In a second area, team expertise on the conjugated use of optical probes
and appropriate chemometric treatment was extended in monitoring tasks
aiming to ensure quality of final products, but also in simplified
characterization tasks. Within this context, influence of different parameters
on glue lines in laminated timber used in buldings was envisaged. In the
same manner it was aimed the evaluation of the transferability of
production models from lab experiments on pharmaceuticals optimization to
large-scale production. Having in mind that high quality of a final product
could be ensured by quality maintenance of the involved processes, the
extension of this concept to wastewater treatment processes was aimed in
order to evaluate the advantages of its use namely reducing laborious work
and associated resources. In sequence of previous work in biological field,
use of IR-spectra, FTIR or NIR, and PLS –regression models were evaluated
concerning its use in pathogenic microbiological identification based on the
respective phenotypic variability, as a rapid lab diagnostic tool to reduce
mortality and save costs.
Within the third research line, concerning proposal of automatic analytical
control, different objectives were established: search of robust
configurations, flow modes and full automatic sample treatment. It was
aimed to propose portable devices with figures of merit similar to the ones
known for traditional flow-injection systems. To this objective appropriate
substrate materials for system engraving as well the inclusion of low
consumption flow driving devices, micropumping pulsed flow, and detector
integration were also searched. Secondly analytical ability of single interface
flow system recently proposed by the team, where sample and reagent
volumes do not contribute to final analytical performance, was performed
concerning kinetic monitoring of charge transfer colorimetric reactions.
Robustness of multisyringe flow methods coupled to liquid chromatography
and to flame- AAS spectrometry, in order to evaluate respective limitations
and figures of merit was aimed. Finally, on-going versatility character of
Sequential-injection concept was further exploited concerning kinetic
discrimination in potentiometric analysis, as a add tool in assessment of
70 phospholipase A2 enzymatic inhibitors in treatment of inflammatory
processes and in forensic applications namely in the postmortem interval
evaluation.
A SPME procedure coupled to gas chromatography mass spectrometry GC(TOF)-MS was succeeded to examine C-14 to C-24 linear and branched
hydrocarbons as indicative compounds of lung cancer in exhaled air of
patients. Headspace-SPME and comprehensive gas chromatography
(GCxGC/(TOF)-MS) were successfully exploited in the analysis of the aroma
compounds of Galega, Carrasquenha and Cobrancosa olives. Statistical
image treatment of results together with PCA-analysis enabled fingerprint
recognition of both the three varieties and extraction methods used. The
volatile compounds responsible for their characterization were tentatively
identified in a bi-dimensional polar/non-polar column set in the GCxGC/TofMS apparatus leading to the reduction of the number of compounds needed
for matrix characterization. Fast screening of 15 androgenic anabolic
steroids was approached by matrix-assisted laser desorption/ionisation
(MALDI-TOF-MS) by settling the best matrix concerning ionisation yield and
interference by matrix ions. The best results were achieved for the 2-(4hydroxyphenylazo) benzoic acid (HABA) and trans-3-indoleacrylic acid (tAA)
organic matrices. Good signals were obtained for concentrations as low as
0.010 and 0.050 μg/mL. The screening revealed positive consistence for
SPE extracts of spiked urine samples.
Ultrasonic assisted digestion revealed particularly effictive procedures for
metal-speciation as well in proteomics. Concerning the last, the decoupling
procedure, was performed in 8 min under the effects of an ultrasonic field
whilst the isotopic labelling evidenced absence of any ultrasonic catalysing
effect.
UV-Vis and NIR spectroscopies were used to monitor an activated sludge
reactor using in situ immersion fiber probes. Calibration models based on
PLS-regression were developed for COD, nitrate concentration (N-NO3-),
and total suspended solids (TSS). The results revealed advantageous use in
controlling the wastewater treatment processes. NIR was also resorted to
evaluate glue lines degradation of untreated and copper azole treated
laminated timber used in buildings. Data treatment by PLS regression
allowed to consider contributions of the adhesive, the hardener, the wood
lamella under the adhesive, the curing temperature and the ageing related
spectral changes. Constraints and merits of laboratory scale approaches and
net analyte signals were evaluated for calibration in NIR technology used in
71 pharmaceutical PAT concept. Chemometric data treatment for FTIR spectra
treatment enabled straightforward discrimination of Burkholderia cepacia
complex clinical isolates at ribopattern with misclassification errors inferior
to 8%.
Automatic flow systems produced by direct milling on poly(methyl
methacrylate) planar substrates and sealed by UV-photopolymerization
were proposed as portable self-contained systems. Prototypes included
micropumping flow and integrated optical detection and were initially
validated on chlorhexidine drug and Ca/Mg determinations. Evidence of
turbulent mixing associated with micropump driven flows was evaluated in
efficient management of fluidized beds and temperature dependent
chemical analysis by accomplishing chemiluminometric gabapentin,
pyrazinamide and indapamide determinations as well reducing sugars in
molasses. Multisyringe flow technique was for the first time successfully
coupled to flame AAS and further exploited in both antioxidants assessment
and screening of phenolic pollutants using in-line SPE-LC. Single interface
flow mode was used to assess thyroid T3 and T4 hormones using different
π-acceptors. Sequential-injection analysis procedures were proposed for
assessment of allopurinol in pharamaceuticals, glucose in milk, vitamins B1
and B6 using a single ISE and kinetic interference discrimination,
potentiometric nitrite in meat, Sn in juices and canned fruits, postmortem
estimation by hypoxanthine and potassium in vitreous humor, and
fluorescent evaluation of NSAIDs based on PLA2 activity

The analytical chemistry group envisaged studies that meet research topics
raised by the ongoing activities. Accordingly, further extension of
chromatographic techniques (e.g., two dimensional GC), chemometric
algorithms, and as well continuous flow methods can be foreseen. It
deserves worth of mention the development of new applications using
selective extraction systems based on the use of hydrophobic membranes
easily changeable for sample preparation in volatiles and semi-volatiles
84 analysis using liquid chromatography. Between these, exploitation of new
possibilities of application to the selective extraction of volatile compounds
present in beverages, namely vicinal diketones, sulphur dioxide, aldehydes
and amines will be evaluated. Analytical procedures for screening of
pollutants control in water courses, particularly NSAID drugs and its related
metabolites will be pursued once they demand for reliable pre concentration
steps and sensitive chromatographic analysis. In this context further
coupling of recently developed detection based on the sensitive molecular
luminescence principles needs the team efforts in the evaluation of
constraints resulting from adequacy of chromatographic eluents composition
and the necessary conditions for sensitive chemiluminometric emission.
Regarding the use of chromatographic approaches in processes control, it
will be finished the study of the influence of malt melanoidins on the
behaviour of xanthohumol and isoxanthohumol in pale and dark beers as
well the evaluation of the impact of the xanthohumol on the physiological
condition of the yeast. In the use of same tools for processes control studies
on the accelerated degradation of geosynthetics will be also conducted,
mainly concerning resistance to laboratorial and natural weathering and to
microbiological attack.
FT-IR spectroscopy will be searched to enable robust methodologies and
appropriate databases that outperform actual commercially identification
systems of bacteria isolates at different levels (genus, specie, strain,
ribopattern or seropatterns and phage type level) using FT-IR. One main
advance is to consolidate in a single work the microbiology, spectroscopy
and chemometrics perspectives on this subject.
Spectroscopic methods such as on near-infrared (NIR), Raman or acoustic
coupled with reflection/immersion probes are among the PAT tools that
have been providing the best results on processes monitoring. The PAT
framework states that the monitoring efforts should be focussed directly on
the process and not after each production step. NIR spectroscopy is a
multitasking technique exploited by the Analytical Chemistry group to
assess quality of pharmaceuticals directly on the production line. In this
new perspective new methods will be evaluated as targets of quality control
i.e., that can be validated using the adopted guidelines for QC validation.
Further studies will be performed on the comprehensive development of NIR
analytical protocols for the quantification/qualification of pharmaceuticals
solid formulations to be used in the pharmaceutical industry.
Concerning sensors and namely with potentiometric transduction a recently
developed device affording the new theoretical highlights on further
extention to trace analysis will be under focus regarding new methodologies
and applications. On the basis of this is the equally easy change allowed for
both sample and internal reference solution, which in first trials enabled
high selectivity even when predicted levels of analyte. On the same trend
85 new applications evidencing the use of cyclodextrines as ionophores will be
shown
regarding

determinations.
Further
extension
of
electrochemical analysis expertise enable to foreseen the development of
simultaneous quantification of metal ions using a chemometrics-assisted
approach with immediate application in the study of new potentially
biodegradable chelating agents for industrial and domestic applications as
part of collaboration maintained with organic synthesis groups.
Exploitation of new flow strategy resorting to individual micro-pumps for
fluid propulsion, sample and reagent introduction and component
commutation, ensuring an effective and precise control of the sampled
volume, either on a time-based or on a pulse counting-based strategy, and
a reproducible transport of the reaction zone towards the detector will
continue under evaluation and evidence through new applications in
environmental and biological applications. Between them, procedures based
on the use of enzymes in ionic liquid environments will be particularly
studied.

5.5.2.1 Objectives
The major goal of our research group is to find solutions for solving
problems related with consumers demand for high quality and safe foods,
genuine and with clear health benefits. Activities carried out in 2009 by
Food Chemistry group followed trends described in previous reports and
focused in food quality, authenticity, and safety, taking into account the
new developments of analytical techniques for food analysis, the
interactions between food components, the overall relationship between diet
and health, health promoting properties of foods and contaminants. Search
for new applications for low value products is another relevant goal of our
group.
87 Hence, main objectives related with food authenticity are the development
and application of molecular biology techniques as sustainable alternatives
to classical analytical methods for identification of foodstuffs adulteration.
This has been a long-standing objective of our group; in the last year focus
was maintained in the improvement of DNA extraction procedures for
quantitative detection of adulterations in processed foods by PCR
techniques. A strong emphasis was put on the identification of species in
foods and construction of a database to be applied on the authentication of
high value food.
Concerning food quality studies different objectives were established:
Correlation between volatile profiles and sensory characteristics, analysis of
macronutrients, micronutrients and bioactive compounds.
Other rather challenging goal of our group is devoted to multi-residue
analyses of food contaminants, namely, pesticides, endocrine disruptors,
mycotoxins, among others. The development of new chromatographic
techniques and environmentally friendly extraction procedures for food
safety analysis is an important goal. Additionally, we are also interested in
study the effects of food processing and storage mechanisms, namely,
understand and minimize the formation of heat-generated food
carcinogenics and found diet chemoprotective compounds that inhibit
hazardous effects. Improve knowledge related with the effect of
temperature and time of storage on chemical composition of foodstuffs.
Build comprehensive mathematical models that describe the effect of time
and of different storage conditions (temperature, relative humidity,
presence of humidity absorber) on both respiration and transpiration rates
of fresh foods.
Understand consumers’ attitudes and behavior towards food safety and
quality, evaluating more specifically: (i) factors that influence risk
perception, and (ii) factors that influence the consumers’ capacity to use the
nutritional information from the food label, as well as the identification of
elements to place on the food package capable of promoting a more
frequent use of the nutritional labeling.
In addition, it is in our objectives to explore new applications for low value
products:
- Reutilization of barley spent grain and Saccharomyces yeast biomass, the
two major by-products from brewing industry.
- Preparation and characterization of whey proteins / polysaccharides
coacervates and their use in micro-encapsulation of bioactive molecules.
Evaluation of flow and viscoelastic properties of whey protein/ chitosan
88 coacervates aiming to evaluate the influence of molecular weight of chitosan
samples. Microencapsulation of oils using WPI/chitosan coacervates
- Production of tailored agar from Portuguese marine algae, to develop an
eco-friendly extraction technique of agar from red seaweeds of the
Portuguese coast (Gracilaria vermiculophylla, an invasive species, and
Gelidium sesquipedale); to develop biodegradable films with tailored
properties.
Main achievements of 2009 can be summarized as follows:
- Quantitative detection of pork meat in processed foods was carried out
using duplex PCR technique and real-time PCR technique using fluorescent
SYBR Green dye. Detection and quantification of soybean as additive to
meat products was performed by end-point PCR and real-time PCR using
TaqMan probes.
- New DNA extraction methods were successfully tested in highly processed
food samples using SSR loci and universal markers.
- For the first time, monitoring of amplifiable DNA in all the stages of a
chemical refining industrial unit of soybean oil was succeeded by end-point
and real-time PCR techniques. Moreover, our group also proved that it is
possible to detect GM soybean along the refining process and that it is
possible to quantify the amplifiable DNA in crude and final deodorised
soybean oils. The study was also extended with success to commercial
refined oils produced from blends and pure soybean.
- Information has been gathered concerning establishment of databases for
sequences of several species commonly found in foodstuffs of the DNA
barcode loci (ITS, trnH-psbA, rpoC1, rbcL, trnL, matK) for plants and CO1
for animals.
- Expedite and simple sample preparation procedures were developed for
extraction of endogenous and exogenous contaminants in food such as
polybrominated diphenyl ethers (PBDEs), mycotoxins (zearelenone and
deoxynivalenol) and multi-pesticide residues. A new chromatographic
technique denominated low-pressure gas chromatography coupled with
mass spectrometry (LP-GC/MS) was used for the rapid and selective
determination of these contaminants. The developed methods were
validated according to international guidelines and applied to the analysis of
foodstuffs.
89 - Isoflavone levels in both roasted coffees and brews were evaluated to
understand the influence of each coffee species (arabica and robusta), roast
degree, brewing procedure and decaffeination on coffee isoflavones.
- A headspace SPME method in combination with GC/MS was validated for
the extraction and quantification of ethanol in cooked meals containing
alcoholic drinks. Estimation of ethanol content was possible for each type of
cooked meals, through the initial amount of ethanol in ingredients.
- Participation with other ten international laboratories on an AOAC
collaborative study to evaluate an affinity liquid chromatography procedure
for measuring immunoglobulin G (IgG) in selected dairy powders.
- Evaluation of the effects of cooking on the degradation of anthocyanins
and anthocyanidins of blueberries (Vaccinium corymbosum L.) and influence
on antioxidant activity.
- The influence of a green tea marinade on the formation of heterocyclic
aromatic amines was examined in pan-fried beef with different marinating
times.
- The effect of alternative sanitation with hydrogen peroxide on quality
parameters of diced garlic (Allium sativum) was evaluated throughout
storage.
- The effect of temperature and time of storage in the levels of biogenic
amines during egg shelf-life was understood. Shell egg storage time during
its shelf-life can be estimated with stepwise variable selection involving
biogenic amine content.
- Volatile composition of several foodstuffs was evaluated and correlated
with sensory characteristics.
- New applications for low value products, such as, barley spent grain and
Saccharomyces yeast biomass and cheese whey were found.
- Study of the flow and viscoelastic properties of whey protein/ chitosan
coacervates. Influence of molecular weight of chitosan samples.
- Measurement of the diffusivity of WPI and chitosan in the coacervates
using the FRAP technique (“Fluorescence recover after photobleaching”).
- Microencapsulation of oils using WPI/chitosan coacervates.
- Microwave-assisted extraction (MAE) of agar from Gracilaria
vermiculophylla, produced in an integrated multitrophic aquaculture (IMTA)
90 system, from Ria de Aveiro (northwestern Portugal), was tested and
optimized using response surface methodology.

Interdisciplinarity will be maintained and a strong inter-laboratory
collaboration will be actively encouraged both with other Portuguese
Laboratories as well as foreign ones (Ostrich, Brazil, Slovene, German).
Considering the increasing number of authorised GM events in the EU and
that there are several events not tested, the development of biomolecular
methods for the detection of other GMO in foods will continue. Additionally,
the food allergies are considered an emergent public health problem,
especially in developed countries. In this context, the study about the
quality and safety assessment of potentially allergenic foods, including nuts
and other foods is planned as prospect work.
The characterization of the social amplification of risk for the Portuguese
consumer will continue.
In the future it is intended to improve extraction and chromatographic
techniques in order to obtained sustainable methods for the determination
of food contaminants. Thus, implementation, validation and application of
new methodologies for the analysis of food contaminants, such as,
pesticides, endocrine disruptors, furans, polyciclc aromatic hydrocarbons,
103 bisphenol, and other food carcinogenic compounds will continue. The
aspects of green chemistry and environmental protection will also be taken
into consideration. A new microextraction procedure called dispersion liquidliquid micro-extraction (DLLME) will be implemented to obtain high
enrichment factors and good yields. In the field of instrumental analysis the
development
of
alternative
methods,
such
as
Heart-cutting
multidimensional GC coupled to mass spectrometry (MDGC/MS), will allow
simultaneously a higher sample capacity, increased separation of trace
compounds in complex matrixes, and enhanced system reliability and
robustness. The Heart-cutting MD-GC is achieved with a Deans Switch
device which permits the selection of a region of a primary column
separation, based upon retention time, to pass to the start of a region of a
primary column separation, based upon retention time, to pass to the start
of a second column for MS analysis or to go to a restrictor column for
waste.
Moreover, it is planned to extend the use of SPME methodologies coupled to
HPLC to obtain enhanced extraction techniques regarded as environmentally
friendly with improved selectivity, sensitivity and rapidity for quantification
of cyprodinil, azoxystrobin, phosmet, fludioxonil, fenhexamid, folpet,
iprodione, tolyfluanid residues in fruits and vegetables.

greenhouse conditions during winter and effects of Good Agricultural
Practices will be assayed.
Studies on the flow and viscoelastic properties of WPI – chitosan
coacervates will continue, namely, evaluation of WPI/agar interactions at
different pHs and ionic strengths by ITC and turbidimetry, assessment of
the flow and viscoelastic properties of whey protein/ agar coacervates.

tailored properties.
A new research topic aims to reduce coffee waste taking a further step into
a “greener coffee”. Coffee waste represents about 90% of the crop, with a
co-responsibility of both coffee producers and importing countries, but the
104 last only deal directly with the spent roast coffee after beverage extraction.
The objective of this study is to determine the use of spent coffee for
horticultural purposes. Taking advantage of the multidisciplinary team of
investigators assembled (Requimte – FFUP and ISEP, CIM – ESA/IPB, and
LIPOR), we will be able to evaluate the chemical composition of the spent
coffee grounds, the alterations induced in the plant, and its nutritional
quality and safety, together with the alterations induced in the soil and
possible environment contamination by leaching of coffee components.
Projects in collaboration with industry include:
- evaluation of the effect of the incorporation of different vegetable oils in
the diet of aquaculture sole. Several parameters are under determination,
including consumer perception of quality and changes in organoleptic
properties.
- close cooperation with mushroom producers for the development of
improved packaging systems aiming at quality retention and shelf life
extension for fresh mushrooms.
- search for new compounds with beneficial health effects, mainly directed
to valorization of beer industry by-products such as yeast and spent grain.
- the development of keratin films from feathers and bovine hair from
leather and poultry industry waste-products aiming the valorization of
feathers and bovine hair that are waste products from leather and poultry
industries. In this area future research involves optimization of process

5.6.2.1 Objectives
The research undertaken by the group is focused in five areas:
i) clean synthetic routes for the preparation of ligands and metal complexes
that can act as biomimetic and therapeutic agents, and nanoparticles for
biological applications,
107 ii) development of chemosensors and chromogenic (electrochromic and
photochromic) systems,

The group main goal is to provide a rational basis to understand the
physical-chemical behavior of interaction of inorganic components with
biological systems, supramolecular assemblies and heterogeneous
(nano)systems and, modeling of interfacial phenomena, which is relevant to
catalytic
processes,

Nanocatalysts were prepared by immobilization of metal salen,
acetylacetonatess and metalloporphyrins with catalytic properties into
functionalized CNTs, mesoporous silica nanoparticles and magnetic
nanoparticles.
We succeeded to functionalize cotton textile with silica nanoparticles that
imparted superhydro- and oleophobic properties.
Mn porphyrins were found to be highly selective in the oxidation of higher

A system based on the organic leuco dye Crystal Violet Lactone was
proposed, exploring its selective interaction with the redox pair
Fe(III)/Fe(II). After spiropyran incorporation this device could be actuated
both by electric and photo stimuli in a reversible way, producing the three
primary colors in solution.
109 Flavyliums encapsulated in nanometric water droplets dispersed in oil
enabled the extension of photochromic transition into basic pH with a good
color contrast. In micelles and pluronic gels the physical-chemistry
photochromic mechanism was analyzed in detail.
Three type of Functional Ionic Liquids were developed: Intrinsically
Photochromic Ionic Liquids, API Ionic Liquids and Luminescent Ionic Liquids.
New luminescent glasses doped with rare earth elements were made in
order to expand the color palette and enhance the performance of the
materials.
New compounds of general formula [M(Ar-BIAN)2]BF4, and [M(ArBIAN)(NCMe)2]BF4, where M = Cu(I) or Ag(I), were synthesized by direct
reaction of [Cu(NCMe)4]BF4 or [Ag(NCMe)4]BF4, with the corresponding
Ar-BIAN ligand.

degradation of DNA.
Important advances in the synthesis of several nanoparticles including
gold(0), silica, silver and magnetic cores for application as sensors and
smart materials for preconcentration in Proteomics Science have been
made.
One tripodal hexadentate chelator that strongly inhibits bacterial growthby
means of iron deprivation was identified in an M. avium infection model.
Fluorescent sensors were prepared using microwave-assisted organic
synthesis. Particularly, one of the sensors showed sensitive fluorescence
quenching response to Zn2+, Cu2+ and Fe3+.
We developed a protocol to synthesize porphyrins that can accommodate a
central ion metal within the porphyrin core and simultaneously behavior as
bidentate or tetradentate ligands. The resulting porphyrins can be selective
totwo different metal ions.
The dissociation of NO assisted by atomic hydrogen on the stepped chiral
Au(321) surface, was studied using a periodic DFT methodology.
110 In the study of the Water Gas Shift (WGS) reaction catalyzed by metallic
surfaces we studied the influence of the surface defects in the performance
of the catalyst − using the Cu(321) surface as model, as well as the WGS
reaction rate determining step on the Au(321) surface.
Atomistic MD simulations were undertaken to study the early stages of the
synthesis of periodic mesoporous silica and a unified view of the entire PMS
synthetic process was gathered.
Valid QSAR models were developed to predict the mutagenicity of alpha,
beta-unsaturated carbonyl compounds that detailed the specific molecular
substructures, as well as accompanying modulating factors. QSAR modelling
strategy was used for probing the anticancer leukaemia activity of
indolocarbazoles or nucleoside derivatives, and for predicting the
complexation of structurally diverse compounds with cyclodextrins.

The objectives of the Physical and Inorganic Chemistry Group described in
section ‘Objectives and Main Achievements’ will be pursued during 2010. .
In order to widen the current research and exploit potential associated
technology new activities will be developed:
1 Extension of flavylium chemistry by (i) encapsulating flavylium salts in a
variety of organic and inorganic matrices; (ii) linking them covalently to
molecular units responsive to metal ions and electron inputs towards
mulktiresponsive
supramolecular
systems;
(iii)
exploiting
dual
126 photochromism based on the photoisomerization of the chalcones and
photoelectrocyclic reactions of chromenes.
2 Development of chiral functional materials (for pharmaceutical and chiral
recognition applications), energetic materials (as micropropelants) and
supramolecular
materials
(for
physico-chemical
and
host-guest
applications).
3 Continuation of synthesis of heterometallic clusters to mimic an orange
protein (ORP), i.e. [S2MoS2CuS2MoS2]3- and related complexes
[S2M’S2MS2M’S2]n-, in which M’ is Mo, or W, and M can be a first row
transition metal such a as Mn, Fe, Co, Ni, in different oxidation states, Pd or
Pt, and group 11 ( Cu, Ag, Au) and group 12, (Zn, Cd, Hg), cations.
4 Design of new chelators possessing the optimal properties to reach the
infection targets for improving the treatment of diseases such as
TUBERCULOSIS and AIDS, will be pursuit, using simple and efficient
protocols based on green chemistry concepts.
5 The evaluation of the effect of tripodal hexadentate chelator in vivo will be
finished. The two compounds that exhibited the best insulin-like action in
vitro will be tested in vivo in a Diabetes type I model in which STZ-rats are
used.
6 The use of iron(III) porphyrin to oxidize cellulose and starch in clean
conditions, leading to high yields and very good selectivity for aldehyde
group will be pursued in order to develop a new, waste free, single step
oxidative modification of polysaccharides, using hydrogen peroxide as a
clean oxidant.
7 Continuation of the synthesis of new iminic ligands with Green chemistry
methods (ultrasounds). Study of the coordinating properties to several
transition metals and their catalytic properties will be tested in: 1 click
chemistry”; 2-ROP (ring opening polymerization) of cyclic esters to yield

5.7.2.1 Objectives
The Biological Chemistry Group at REQUIMTE is concerned with addressing
a wide range of scientific matters at the chemistry-life sciences interface. In
2009, much of our work was centered in the fundamental research on
natural and synthetic compounds, materials, microorganisms, and diseases,
leading to a mechanistic view, to be applied in the resolution of real
scenario problems, by focusing on the following objectives:
- To evaluate the effect of acetyl-Lcarnitine (ALC), and the MAO-A inhibitor
chlorgiline, in MDMA-induced neurotoxicity at the mitochondrial level.
131 - To evaluate the toxic effect of MDMA and its MDMA metabolites in adult
rat left ventricular myocytes.
- To evaluate the feasibility of lysine acetylsalicylate (LAS) as an antidote
against paraquat intoxications in the rat.
- To evaluate the current therapeutic protocol usually performed to treat
human paraquat intoxications, in post-mortem studies.
- To study adrenaline mediated signaling, metabolism and transport in rat
isolated cardiomyocytes.
- To report forensic cases, related to cocaine, mercury and alcohol
intoxications.
- To evaluate the expression of hepcidin following unfolded protein response
(UPR) activation.
- To evaluate the effect of prolonged consumption of red wine (RW) in the
rat liver.
- To clarify the role of P2Y receptors on neuronal and glial signalling in
health and disease.
- To investigate the role of adenosine receptors in hypertension by caring
out the morphological characterization, distribution and quantification of
adenosine receptors subtypes in the cardiovascular system.
- To investigate putative role of adenosine-angiotensin II interactions in
hypertension and diabetes mellitus nephropathy.
- To evaluate the anticancer and anti-inflammatory properties of adenosine
receptors and of polyphenolic compounds.
- To develop yeast models expressing human proteins involved in the
modulation of cell death pathways and the screening of compounds that
target these proteins.
- We have specific interests in the application of matrices of natural origin
(vegetal and animal, terrestrial and marine) in different areas of the
science, to find new strategies with multidisciplinary approaches for the
search of compounds with potential health benefits. It is taken into account
the new developments of analytical techniques for their analysis, the
interactions between their metabolites, the overall relationship between
composition and bioactivity. Major objectives of the research group are
implementation, validation and application of chemical and biological
methodologies for the analysis of components in several matrices and the
132 search for new bioactive compounds. Emphasis on primary (organic acids,
amino acids) and secondary metabolites (phenolic compounds, alkaloids,
carotenoids, phytosterols, volatile components) is given.
-To characterize horizontally transferable genetic elements carrying
resistance or virulence genes (HTG), and to evaluate factors interfering with
the bacterial acquisition of these features, in order to assess the risk for
human health of HTG containing bacterial isolates of animal and food origin
- P2Y1 and P2Y12 receptors are the main subtypes triggering astroglia
proliferation, an important process observed upon injury of the CNS. P2Y6
receptors present in activated microglia may constitute an interesting target
to control excessive astrogliosis.
- Modulation of adenosine receptors can minimize neuronal injury in
Alzheimer’s disease.
- Coleon U is a potent and selective activator of the novel PKC-delta and –
epsilon.
- p53-Mediated cell cycle arrest and apoptosis is differentially regulated by
PKC isoforms through p53 phosphorylation and p53 subcellular relocalization.
- 2-Chloroadenosine positively influences the progression of diabetic
nephropathy.
- There is a high occurrence of antibiotic resistant enterococci, which
includes strains belonging to high risk clonal complexes in pigs, as well as a
diversity of antibiotic resistance genes in Enterobacteriaceae from animal
samples. Besides the horizontal transfer of resistance to several antibiotics
we observed, in pigs isolates, a high rate of transconjugants containing the
tcrB gene, encoding for copper resistance, which could act as a selective
agent of multi-drug resistant bacteria.

Also Spodoptera littoralis, an insect whose larva constitutes a frequent pest
of tomato (Lycopersicon esculentum) crops, will be studied. Despite the
biological potential of some tomato compounds, namely as cholinesterases
inhibitors, several of them are toxic. The characterization of molecules
resulting from sequester, metabolization and accumulation of compounds by
the larva, retaining the protective effects but with lower toxicity, is the
challenge. S. littoralis/L. esculentum system will be studied concerning
metabolomics and bioactivities.

A research line devoted to marine organisms has started. As a consequence
of the exposition to challenging environmental conditions, marine organisms
synthesize secondary metabolites with promising pharmacological
properties. With this regard, metabolomics and biological potential
approaches are currently taking place on Echinodermata species and on
macro algae.
143 Taking into account the emergence of antibiotic resistance and based on the
results already achieved by our investigation group, the knowledge and
surveillance of this dynamic process assumes special importance, being
noticed the interest of including other niches as well as approaches not
confined to the antibiotics neither to the planktonic bacterial growth.
Therefore we intent to evaluate: a) impact of antibiotics on the bacterial
diversity and antibiotic resistance in aquacultures and in ready-to-eat
salads; b) role of biocidal substances and/or products in the selection of
clones and mobile genetic elements associated to the dispersion of antibiotic
resistance; c) biofilm formation ability of successful clones. Development
and integration of typing methodologies (at plasmid and bacterial level) will
be pursued using multilocus typing and high throughput spectroscopic
methodologies. High throughput spectroscopic methodologies might
constitute a reliable tool to detect differential features associated with
epidemic clones and eventually to optimize and impulse epidemiological
surveillance studies.

6.1.2.1 General Objectives
As indicated previously, this Research Line has been transformed into Novel
Compounds from Renewable Sources , in the framework of the new internal
organisation of the Laboratorio Associado proposed in our 2008 5-year
report.
In 2009, its main objectives were
(1) to develop and implement bioprocesses for conversion of industrial byproducts to value-added specialty or bulk chemicals and polymers.(2) to
discover new chemicals or new sources of known chemicals in natural
products with interest for pharmaceuticals or food additives; (3) to discover
new chemical reactions, using the green chemistry paradigm, with
application in the synthesis of novel natural products, metabolites or
chemical structures of practical interest in pharmaceutical, environmental,
agrochemical, flavour and fragance industries and related activities
Research on natural products from plant material has produced several
interesting results, with ten papers in refereed journals. Reactions of
terpenes following green chemistry protocols, using new catalysts or
alternative solvents led to six papers.
145 Studies of biopolymers expanded from previous years. Chitosan was the
target of several studies, ranging from food applications to prospective use
as bodegradable scaffold for tissue engineering. Activities in bio-synthesis of
natural biodegradable polymers continued, including a range of external
collaborations. Transformations of low-molecular weight carbohydrates have
also been studied. Nine papers resulted from this group of studies.
Biomass as a source of chemicals was studied from several angles, including
the production of biodiesel. Seven papers resulted from this activity.
Several “industrial” collaborations were developed Apart from the continuing
efforts on cork, olive oil and beer, which resulted in one patent submitted,
new joint activities started. A new contract was established with a coffee
company aimed at the use of residues as biomass source of chemicals. A
collaboration with a hospital on tissue engineering, partially supported by a
charity, was started.
Collaborations with State Laboratories on biomass utilization and chemicals
from marine resources continued.

1. To pursue research in some of the domains already in course, to grant
quality, authenticity and safety of food products, and to start new topics
aiming the improvement of the safety of consumers and strengthening the
contributions to the resolution of public health problems related with food
science.
2. To start a new line aiming at the measure of consumer attitudes towards
food, nutrition and health, covering such aspects as consumer’s perception
of risk; use and content interpretation of food labelling; and appraisal of
new food related technologies.
3. To characterize horizontally transferable genetic elements carrying
resistance or virulence genes (HTG), and to evaluate factors interfering with
the bacterial acquisition of these features, in order to assess the risk for
human health of HTG containing bacterial isolates of animal and food origin.
4. To apply biological techniques, namely, PCR techniques, and the
development of new DNA based novel techniques to access food quality and
authenticity.
5. To increase collaboration between the groups settled at the LA and the
governmental and industrial partners to implement greener methodologies.
1.Establishment of databases for sequences of several species found in
foodstuffs of the DNA barcode loci: ITS, trnH-psbA, rpoC1, rbcL, trnL, matK
for plants and CO1 for animals
2.Detection/quantification of soybean as additive to meat products by endpoint and real-time PCR using TaqMan probes
3.Detection of GMOs in refined oils by end-point and real-time PCR. For the
first time it was possible to detect GM soybean at all stages of a soybean oil
refining industry and to quantify the amplifiable DNA in crude and final
deodorized soybean oils
4.Detection of a new plasmid conferring resistance to extended spectrum
cephalosporins (CMY-2) in the European spread OXA-30 Salmonella clone.
This finding is of relevance to trace the origin of this worrisome mechanism
of resistance. It was possible to associate the dissemination of the enzyme
TEM-52, conferring resistance to broad spectrum cephalosporins in
enterobacteria from animals and humans, to an epidemic plasmid of IncI
type. The observation, in Gram+ bacteria, of the involvement of conjugative
transposons in the tetracycline resistance acquisition, might justify the rapid
bacterial adaptation to these antibiotics and genomic changes thereof
5.Multi-residue analyses of food contaminants: heavy metals and pesticides,
endocrine disruptors, and mycotoxins, using environmentally friendly
procedures
6.Understanding and minimizing the formation of heat-generated food
carcinogens and finding diet chemoprotective compounds
7.Optimization of a traditional method for agar extraction applied to
Portuguese seaweeds from Ria de Aveiro. The resulting hydrocolloids, with
enhanced gelling ability, may find similar applications to commercial agar as
texture agents in food industry
8.Preparation and characterization of whey proteins/chitosan coacervates to
be used in microencapsulation of bioactive molecules
9.Study of food products functionality by monitoring phenolics, organic
acids, fatty acids and volatiles composition in extracts of several vegetal
materials used for human consumption and in the brewery industry
10.Understanding the attitudes of consumers towards food safety/quality,
evaluating factors that influence risk perception and capacity to use the
nutritional information from food label

Chemistry
Materials Science and Engineering
This line is now named Clean Chemical Processes
The main objectives for 2009 were:
Development and implementation of clean separation processes, namely
involving solvents that allow for more sustainable processes (e.g.,
supercritical fluids), and new materials with improved properties such as
membranes and natural-based adsorbents. A particular emphasis shall be
given to the development of integrated processes combining (bio)reaction
and separation.
Development of separation/reaction processes involving ionic liquids using
different approaches. Ionic liquids may be used as reaction media,
integrated in phase transfer processes as well as in (bio)catalytic reactions,
and integrated into polymeric materials in order to modify their properties.
Implementation of clean synthetic routes for the preparation of ligands and
metal complexes.
Development and implementation of monitoring, modelling, automation and
control of bio/chemical processes, with a particular emphasis on the use of
molecular and nano probes.
New “green” strategies were developed either to synthesize or to process
synthetic and natural polymers. Molecularly imprinted polymers (MIPs) with
high specificity towards an enantiomeric molecule were synthesized in
scCO2. The polymeric materials were tested as stationary HPLC phases
showing chiral recognition capability.
Catalyzed hydrogenation reactions of terpenes in mono- and bi-phasic
conditions in high-pressure carbon dioxide were studied and optimised.
Novel processes were designed to prepare new porous structures, namely
stimuli-responsive membranes and chitosan scaffolds without any solvent
residues and with new biocompatible cross-linkers.
New membrane materials able to respond to non-mass external stimuli
(electromagnetic radiation and external magnetic fields) are under
development for gas separations and separation of biologically active
compounds.
The creation of new magnetic nano and micro structures for the affinity
purification of biomolecules, and the development of new HTS techniques
for the selection of affinity ligands for important target proteins was
successfully achieved.
Activated carbon obtained from natural materials were prepared and used
as adsorbents to remove pharmaceutical pollutants. (Cs)Al-SBA-15 or
DEAPTS/MCM-41 were found to be efficient catalysts for the pyrazole
alkylation with different reactive alkyl bromides under thermal activation.
The effect of nano-confinement in zeolites (pore sizes from 2.8 to 6.8 nm)
on the molecular dynamics of a LC was evaluated.
Clean synthetic procedures using microwave and ohmic heating are being
applied as the default techniques in the synthesis of new molecules with
application in Medicine and Industrial Processes.
Novel gas separation processes, coupling pressure swing adsorption (PSA)
and simulating moving bed (SMB) technologies are being studied. Cryogenic
adsorption of nitrogen, hydrogen and light hydrocarbons on several
activated carbons and MIL-53 (Al) metal-organic framework (MOF) are
undergoing.
The real-time monitoring of mammalian cultures as well as PHA producing
cultures was performed through a combination of respirometric, titrimetric,
156 2D-fluorometry and chemometric techniques. On-line metabolic
analysis was successfully applied to PHA producing systems.

Technology (CITEM 2010) will be organized by a researcher of REQUIMTE.
The main research directions will be kept, with a new emphasis on
collaboration with the thematic area on Novel Compounds from Renewable
Sources, under the theme Biorefineries.
Novel clean processes using alternative solvents (supercritical fluids, ionic
liquids, etc.) will be developed. New membrane materials, able to respond
to physiological and/or non-mass external stimuli will be developed for
improved separation processes and diagnostics.
Advanced electrochemical oxidation processes as well as new integrated
(bio)technologies will be investigated, focusing especially on those with
relevance to the removal of emerging pollutants from drinking water and
from pharmaceutical/hospital wastewater.
Adsorption-based catalysis, storage and separations will be also studied,
using either natural or novel materials as adsorbents. Advanced modeling
tools, from CFD to molecular dynamics, will be applied for process
optimization.

A wide range of activities have been developed under CHEMICAL BIOLOGY
AND BIOENGINEERING: Biochemistry, Bio-Spectroscopy (EPR, NMR,
Mossbauer, X,-Ray Crystallography), Bio-electrochemistry and Bio-sensing,
Microbilogy, Molecular Biology, Bio-informatics, Molecular Interactions,
Bioengineering, etc. Common topics emerged and a general orientation is
quite visible.
We foresee that the future research will try to further develop these points
with an emphasis on the application of quite sophisticated tools such as
NMR, EPR and Crystallography, ENDOR, ESEEM and EXAFS, also taking a lot
of advantage of Molecular Biology tools, Genomics, Proteomics and
Metallomics. Theoretical calculations will enable a further understanding of
the molecular mechanisms involved that cover most of the Biocycle of the
elements (H, N, O, S and C). Applications will emerge naturally and drug
design and biosensors will be an important frontier to look for. New
techniques in the area of nano-materials and oriented molecules seem
promising. The Biological Chemistry will have a tendency to overlook more
directly to drugs and diseases..
Without being exhaustive a few topics are here lined up:
Structure-Function of Metalloproteins
Molecular simulations and quantum mechanics techniques. EPR and AFM of
the samples with aligned virus+protein/peptides aggregates.
Development of a wide range of electrochemical biosensors using
unexplored enzymes. Proteomic studies of sulfate reducing bacteria and of
human skin.
Biochemical and genetic characterization of the enzymes involved in the
perchlorate reduction pathway.
Structural and functional NMR studies of different system.
Water and solute transport, Mathematical Dynamic Models
164 Studies on food components
Plant cell wall degrading enzymes
Drug design, study of the interaction of metallodrugs with proteins at the
molecular level.
Evaluation of the mechanism of toxicity of ecstasy at the mitochondrial
level.
Development of a safe formulation of paraquat.
Evaluation of the mechanisms of neurotoxicity of drugs.
Use of normal and cancer human proximal tubular cells for development of
selective anti-cancer drugs.
Development of biological treatment processes for water and wastewater
will continue focused on the process optimization.
6.5 Catalysts, Solvents and Non-Toxic Compounds
Research Line Title: (RL-CHEM-750006-53) - Catalysts, Solvents and
Non-Toxic Compounds
Principal Investigator: Baltazar Manuel Romão Castro
Biological Sciences
Health Sciences
In the framework of the new internal organisation of REQUIMTE, and
according our proposal submitted in the 2008 5-year report, the content of
this research line was disseminated into other lines reflecting more closely
the referred activities. As also previously done, it is herein introduced the
new set of activities under the "ANALYTICAL CONTROL AND PROCESS
AUTOMATION". Between them it was aimed for 2009:
165 - Development of robust analytical tools with usefulness in the evaluation of
naturally available materials for removal and recovery of heavy metals.
- Use of NIR probes to assess degradation factors on glue lines of laminated
timber used in buildings and in wastewater treatment control.
- Establishment of fats and fatty acids composition of feeds and their
influence on ruminant meat using chromatographic screening tools.
- Establish the advantages and drawbacks of automatic approaches for the
screening of scavenging capacity of compounds and matrices.
Several natural materials and yeasts available in huge quantities in Portugal
have been studied as sorbents for heavy metals in industry like
galvanoplasty effluents: peanut hulls, almond hulls, marine algae and
inactivated Saccharomyces cerevisiae yeast. For this purpose multi-stage
processes, combining biosorption and chemical methodologies, were
developed to remove and selective recovery metal ions. Further kinetic,
equilibrium and column studies were performed. Combined processes based
on
incineration
followed
by
electrolysis/
alcalinization
or
pH
adjustment/oxidation were compared and of-line control methodologies
based on anodic stripping voltammetry and spectroanalytical techniques
developed.
UV-Vis and NIR spectroscopies were used to monitor an activated sludge
reactor using in situ immersion fiber probes. Calibration models based on
PLS-regression were developed for COD, nitrate concentration (N-NO3-),
and total suspended solids (TSS). The results revealed advantageous use in
controlling the wastewater treatment processes. NIR was also resorted to
evaluate glue lines degradation of untreated and copper azole treated
laminated timber used in buildings. Data treatment by PLS regression
allowed to consider contributions of the adhesive, the hardener, the wood
lamella under the adhesive, the curing temperature and the ageing related
spectral changes.
Several chromatographic approaches were developed to assess the effect of
linseed oil and maize silage diets in ruminants meat fats profile. Moreover, a
new strategy based on the use of microbial fatty acids was resorted to
understand the contribution of solid associated bacteria to microbial mass in
the rumen.
Automatic scavenging capacity evaluation against ROS and RNS compounds
were critically evaluated, considering on-line generation of reactive species,
applicability of methodology to plant material, food extracts and
166 pharmaceuticals. Standardization is pointed out as the next up most
importance future outcome.

168 6.5.4.2. Future Plans
Results obtained by the research group considered the application of new
procedures based on modern analytical instrumentation to solve different
problems of products for human usage, and to diminish the environmental
impact
of
human
activities.
Accordingly,
further
extension
of
chromatographic techniques, chemometric algorithms, and on-line
monitoring techniques can be foreseen. Some of these activities started
recently and are shortly described as: i) development of molecular organic
framework materials, such as Zn(BDC)(H2O) coordination polymers,
recently synthesized and characterized, with promising usage in selective
removal of organic toxic PCBs; ii) Inorganic-organic networks with
lanthanide ions to be used as vehicles for selective target delivery of drugs,
which initially will demand for analytical characterization and optimization of
procedures related with drug inclusion and delivery; iii) Validation of
automatic manifolds for scavenging capacity evaluation will be pursued as
well the application extension to the analysis of biological materials; iv)
studies on the accelerated degradation of geosynthetics, in collaboration
with the Department of Civil Engineering of the Faculty of Engineering of
Porto, mainly concerning the determination of degradation compounds in
geotextiles exposed to laboratorial and natural weathering.
7. Other Activities
7.1 Internal Services and Resources
1. EQUIPMENT. Open access to all equipment in REQUIMTE has been a
general policy since its creation. The granting of the status of “Laboratório
Associado” allowed the hiring of researchers and technicians to manage the
available facilities and organize services, thus greatly improving the
accessibility by all researchers to a larger equipment park. The national
equipment program allowed the modernization of many research services
and the creation of several networks of users for large scale instruments,
thus reinforcing the principle of open access for the scientific community.
The success of REQUIMTE in this program, with a total approved financial
support of 4.3 M€, allowed for: (a) the upgrade of the current NMR
facilities, within the framework of the approved national network; (b) the
set-up of a large Parallel Computing Facility; (c) equipment for Biomolecular
Analysis (with CREM, a Biology Research unit UNL); (d) equipment for Clean
Technologies and Chemical Engineering (with ITQB, UNL); (e) equipment
for Food and Environmental Analysis; (f) Single Molecule Detector and Flash
Photolysis Infrastructure (with Research Centers at IST/UTL); (g) X-Ray
Crystallography Infrastructure for Small Molecules (with CICECO); (h)
169 Scanning Electron Microscopy for the characterization of Nano-structured
Materials, in the framework of the approved microscopy national network.
2. INTERNAL JOINT PROJECTS. Since 2004, in a strategy to reinforce
collaboration between researchers in Porto and Lisboa, REQUIMTE has
funded 15 projects submitted jointly by at least two researchers from each
location (total cost 350k€). This funding was to be considered as seed
money to submit larger proposals to external agencies, which met with
considerable success. The deadline for a new call is April 30th,2010.
3. PRODUCTIVITY APPRAISAL. REQUIMTE uses well defined performance
indicators to distribute funds and resources among its members. It is very
well accepted by the community and improved the overall performance
without hindering collaboration among researchers and research groups.
The indicator is fed by data for the past five years and depends on number
of publications and their impact factor, on the number of MSc and PhD
students and degrees awarded.
4. UPCOMING CONSORTIUM. The creation of M2P2 (Molecules, Materials,
Processes and Products), a consortium established by REQUIMTE, CICECO
and LSRE-LCM, will foster the sharing of equipment, of multidisciplinar
projects and doctoral programs. By drawing on different research cultures
and sharing good practices of research and of technology transfer, the new
consortium is expected to enhance the performance of the individual LAs
and to allow a more competitive role in the European Research Area.
7.2 External Services and Resources
REQUIMTE is from the onset a science-driven institution that is already
acknowledged in Portuguese Chemistry and Chemical Engineering as a
leading player in technology transfer, spin-off creation and scientific service
provision.

and presently counts with the participation of 37 PhD students.
During 2009, 22 Ph.D. dissertations were concluded. REQUIMTE researchers
participate in 15 Master Programs and have supervised 120 M.Sc.
dissertations.
REQUIMTE is involved in joint and research program between MIT and
seven Portuguese Universities in the area of Engineering Systems initiated
in 2006. One of the four key areas of the program – Bioengineering (BIO-E)
- is coordinated by a REQUIMTE researcher and ten other REQUIMTE
researchers are actively involved in the educational programs of BIO-E: i)
lecturing in the advanced one-year course, and ii) supervising joint PhD
students with MIT researchers.
172 REQUIMTE participates in European training networks: MRTN-CT-2005019335 Translocation (2006-2010); “Molecular Basis of Antibiotic
Translocation”;
and

Regular monographic courses are organized by REQUIMTE researchers
(more info at http://www.requimte.pt/index.php?section=31) as well as
other courses such as the “Hands-on Course in Proteins and Proteomics”.
These courses are attended by researchers from national and international
academic and industrial institutions.
In the framework of “Programa CIÊNCIA 2008”, REQUIMTE has opened, in
2009, 68 positions for "BOLSAS DE INICIAÇÃO À INVESTIGAÇÃO". As
previously, we have received a considerable number of applications and
selected undergraduate students to fulfill all positions.
REQUIMTE is also involved in training activities for under-graduate students,
having established protocols with several high schools in Lisboa and Porto
areas.
7.5. Outreach/Science and Society
REQUIMTE has been an enthusiastic participant in activities related to the
public awareness of Science, stressing current concerns of Green Chemistry.
Researchers participate in all activities organized by national bodies and by
the universities, targeting primary and secondary school students, school
teachers and the general public. Furthermore, REQUIMTE’s researchers
actively participate in brokerage events where they improve their industry
need awareness and where industry collaborations are established.
REQUIMTE continues its involvement with the project Casa das Ciências
(started in 2008, with an annual funding of k€100 by Fundação Calouste
Gulbenkian , http://www.casadasciencias.org) which is creating a repository
of open education resources with the aiming to improve Science teaching in
schools.
REQUIMTE maintains its annual participation in many initiatives organized
by the Universities, such as “Expo FCT”, “Chemistry Days”, “Mostra da
Universidade do Porto” and “Universidade Junior” attracting many hundreds
of secondary school students and their teachers, who come to attend
lectures, watch exhibits, and participate in experiments and lab tours.
173 Every year, REQUIMTE participates in the events organized by “CIÊNCIA
VIVA” (the Portuguese Agency for Public Awareness of Science), such as
“Science and Technology Week”, “Fórum Ciência Viva” and opportunities to
welcome young high school students to research laboratories during the
Summer vacation.
REQUIMTE’s members have participated in the organization of “Olimpíadas
da Química”, a tender of chemistry for young high school students.
Club Math is an event organizedby the Mathematics Depatment and during
the event high school students visit the Requimte and participate in
activities.
The “European Researchers Night” initiative counted in 2009 with the
participation of REQUIMTE researchers. This initiative offers the large public
the unique opportunity to discover the researchers and their world.
REQUIMTE projects have been presented at several instances in the national
TV programs devoted to science, namely “Ciência 2010”, . A new initiative
will lead to a short TV serial on the public understanding of science.
Using its special expertise, REQUIMTE organizes regularly monographic
courses open to all academic and industrial researchers. Detailed
information in http://www.requimte.pt/index.php?section=31.
REQUIMTE participated in Brokerage Events such as the 4th Innovation
Days (organized by the national Agency for Innovation) where researchers
showed its R&D project results to the industry. Such events are always
taken as an excellent opportunity to develop industry collaborations.
The REQUIMTE member Paulina Mata published (in co-authory) the
educational book “A cozinha é um laboratório” (The kitchen is a laboratory)
and participated in several events of science divulgation to the public in
general.
7.6. Organization of International Events
In 2009, REQUIMTE’s researchers were involved in research international
events:
ESF Exploratory Workshop - PESC - LESC – EMRC: Bionanotechnology:
Development And Application Of Principles Of Nano- and Bio-Sciences To
Sensing, Diagnostics & Therapy (August, 31 – September, 2; Sintra,
Portugal). Co-Covened: Ricardo Franco
174 1st International Congress on Analytical Proteomics - ICAP / 5th National
Procura meeting (September, 30 – October, 3; Caparica, Portugal). CoChairs: Isabel Moura, José-Luis Capelo, Carlos Lodeiro, Mário Diniz.
II International AMONET Meeting: Women Empowerment in Science (12 –
13 October; Lisbon, Portugal). Organizing Committee: Ana Lobo, Florbela
Pereira, Maria Manuel Marques, Vasco Bonifácio, Ana Maria Phillips, Ana
Lourenço.
8. Internal evaluations
8.1. Summary of internal evaluations during 2009
REQUIMTE actually started as a Network with a common Advisory
Committee. This fact has probably been the reason why the biannual visits
of this Committee have always been regarded as very important, and the
advice of its members has actually shaped the Network. It was instrumental
into helping bring it to the current status of Laboratorio Associado.
The recommendations of the last visit of the Advisory Committee in 2008
highlights the good productivity of each group by the increase number of
articles published during the period.

_Report_7_8_July_2008.pdf).
8.2 Future internal Evaluations plan for 2010
The leadership is considering a major overhaul of the internal quality
system to fine tune current procedures and to steer REQUIMTE towards
stronger internal cohesion, higher international standards and a more
efficient technology transfer effort. After the last visit of the Advisory
Committee in July 2008 and the preparation of the proposal for renewal of
the LA contract, the following lines will be pursued:
• Strengthen the role of the Advisory Committee with more frequent visits,
preferably coinciding with the plenary REQUIMTE scientific meetings;
• REQUIMTE leadership will seek strategic guidance and advice from the
Committee on plans and initiatives to be taken;
175 • Research groups shall have a formal assessment and advice from the
Committee;
• The performance of the researchers under contract of REQUIMTE will be
evaluated by the Committee and the renewal of their contracts will be seen
to be dependent on the Committee recommendation;
• A set of indicators of individual performance will be developed and agreed
upon with the researchers to be then used on a regular basis;
• Indicators will follow bibliometric performance but also all other areas in
the mission of REQUIMTE, namely technology transfer, services to
government and the community and the public awareness of science,
especially in the area of Green Chemistry;
• The internal distribution of funds and resources will be made explicitly
dependent on the performance indicators as has been the policy of
REQUIMTE since 2007.
The next visit of the Advisory Committee is scheduled for December
2010/January 2011.
9. Future Objectives
The research activities of REQUIMTE refocused in 2009 on a slightly
modified set of five thematic areas. This has facilitated the launching of
projects around the Biorefinery concept, especially related to bioenergy and
biomass resources, and the integration of more researchers into the main
research vectors of REQUIMTE. These developments will continue in the
next few years, and they will contribute to an increased external awareness
of REQUIMTE’s activities. To achieve these objectives we expect a
significant contribution from the 24 researchers that were hired in 2009
within the program CIENCIA2008.
In the next few years, REQUIMTE intends to raise its national and
international profiles. At the national level, the M2P2 association with two
other Laboratorios Associados will continue be used to promote the image of
Chemistry and to open new lines of research and transfer of technology in
the interface with their areas of expertise. At the international level, the
recent launched doctoral program on Sustainable Chemistry will be
integrated into an international Network.
176 Although keeping the strong science-driven orientation, REQUIMTE will
endeavor to progress further in technology transfer to industry and public
service, assuming full responsibility as a Laboratório Associado for Green
Chemistry. Being a network itself, REQUIMTE will use its internal experience
to develop stronger ties within the M2P2 association, with two other LAs in
Porto and Aveiro. The array of research services that this association will
provide will benefit scientific productivity, in particular of young researchers
in interdisciplinary collaborations.
