A. Annual Report - Electrochemistry and the Environment
During 2009 the 12 members of the Electrochemistry and the Environment
(E&E) group (11 staff of UM and 1 "Ciência 2008" program post-doc)
participated in 26 international and national conferences with presentation of
36 poster and 7 oral presentations. A total of 19 papers were published in
international journals during the year and a further 17 have been accepted for
publication in 2009. Members of the group were authors of 7 papers published
in conference proceedings, 1 book chapter was published by an international
editor and two books were published by a Portuguese editor (through the
"Sentir a Ciência" project).
Members of the staff of the research group supervised or co-supervised 12
students for doctoral thesis research and 8 students continue preparation of
their master theses. During 2009 5 MSc students successfully completed their
degrees.
Although a substantial part of the work reported by members of this research
unit involves internal collaboration of staff within each programmed sub-task,
a high percentage of the published results continue to be a consequence of
interaction of members with other groups from the Chemistry Research
Centre, from other research centres of the University of Minho, from other
Portuguese research centres and through international contacts.
A post-doctoral research fellow, Dr Iwona Biernacka contracted by the Centre
through the Ciência 2008 (FCT) program, began work in September 2008
and is now fully integrated into projects being developed by members of the
Electrochemistry and Environment group. She is currently collaborating in the
development of heterogeneous catalysts.
A1. Unit description
CQ-FCT is a research unit that functions within the University of Minho
promoting research in the domain of Chemistry. The internal regulations of the
Chemistry
Research
Centre
(CQ)
determine
the
organization
and
management procedures of the research unit. CQ members are either fulltime equivalent researchers (FTEs - with a PhD degree) or associate
members (PhD students and young researchers supported by externally
financed projects). In December 2009, the CQ-FCT had 37 FTEs and 73
associate members.
2
The members of the Centre are distributed between 4 groups according to
their scientific interests and affinities:
Electrochemistry and Environment (12 FTE and 22,5 collaborators);
Synthesis and Application of Heterocycles (13.5 FTE and 26 collaborators);
Synthesis and Application of Amino Acids (6.5 FTE and 13,5 collaborators);
Biological Chemistry (5 FTE and 11 collaborators).
The organization of the CQ-FCT is based on a scientific council that includes
all FTRs and a coordinating committee. The Director of the research unit
presides over a coordinating committee that is composed of the four principal
investigators and one delegate from each research group. This committee
coordinates the research policy, plans the activities of the unit and prepares
the annual and pluriannual plans, reports and budgets for approval by the
scientific council. The unit Director officially represents the unit, convenes the
scientific council and coordinating committee meetings and implements the
decisions of these bodies.
Preliminary contacts have been established to create an advisory committee
that will accompany and advise future research activities of the Centre, in
accordance with FCT regulations. The present financial constraints and the
uncertainty concerning future financial support, are however expected to
delay the full implementation of the activity of this committee.
A2. General objectives
The three scientific domains that have been identified as the basis for
research within the Chemistry Research Centre are health, the environment
and new materials. The members of the Centre are distributed between four
groups that have targeted the above topics as domains of particular interest.
Currently the members of the Centre, most of whom are teaching staff of the
Department of Chemistry, also participate in Masters degree courses in
"Medicinal Chemistry" and "Techniques of Characterization and Chemical
Analysis". An expected outcome of this interaction is that topics for final year
theses are focused on these areas of specialization. A Masters degree course
in "Chemistry - Further Education for Teachers" admitted students for the first
time this year and is expected to foster a closer working relationship with local
schools.
3
Many of the projects under development within the "Electrochemistry and the
Environment"
research
group
are
based
on
the
preparation
or
characterization of new materials which directly or indirectly reduce chemical
impact on the environment. These materials or processes are applicable in
domains of catalysis, environmental or food-related analytical chemistry, the
implementation of environmentally-friendly synthetic methods, the recovery of
energy from effluents, the application of safer and more efficient electrolyte
components in electrochromic devices and the use of functionalized
nanostructured components in optical and biological applications.
A3. Main achievements
The results of the research carried out by the Electrochemistry and
Environment group have been published in international journals, presented
at specialist conferences and reflect the range of interest of the group
members. The main achievements in 2009 include the development of novel
synthetic routes using non-toxic medium, the preparation of zeoliteencapsulated metal complex catalysts, the photo-oxidative stabilization of
polymer formulations, the improvement of microbial fuel cell performance, the
identification of structure-activity relationships of potential anti-oxidants, the
evaluation of antioxidant capacity, the formulation of multi-functional
components for electrochromic display devices and new procedures for
preparation of improved nanoparticle-based materials.
A4. Integrative/multidisciplinary activities
Activities involving members of the E&E group may be cited to demonstrate
the interaction of these researchers with other groups. Joint publications have
resulted from collaboration in the studies of compounds prepared by
colleagues from the Heterocycles group. Projects with members of Biology or
Physics Centres (UM) have been based on the application of analytical or
physical methods to the characterization of biological systems and to various
specialized materials. Interactions with colleagues from the Faculty of
Engineering (UM) continue to stimulate collaborative research in the domains
of energy conversion, catalysis and polymer photodegradation.
Reference to PhD student projects provides examples of co-supervision
where interdisciplinary topics are explored by the group. The effectiveness of
4
these activities can be measured by the contribution that multidisciplinary
papers make to the list of publications.
A5. Outreach activities
The members of the Chemical Research Centre/Department of Chemistry
continued to invest a sustained effort in outreach activities to promote a
favourable public image of Chemistry within the secondary school population.
A wide variety of projects were included in the initiatives prepared and
implemented in 2009. These include presentations on topics of special
interest by members to secondary school students participating in organized
day-visits to the Centre or Department. Several lecturers/researchers also
accepted invitations to present these special topics in local schools. The
objective of these activities was to stimulate interest in the study of Chemistry
and attract students to the degree courses available in the Department of
Chemistry. Examples of the other activities include "Vamos Kimikar"
(laboratory classes for 11-13 year olds), "Olimpíadas de Química" (a team
competition for 13-14 year olds), "QSI - a closer look at Chemistry" (a weeklong activity for 16-18 year olds hosted by the Chemistry Department) and
"Science in the summer" (a summer project placement for 16-18 year olds).
During the year more than 1600 school-children of ages between 12 and 17
and almost 250 school-teachers were directly involved in these activities.
Groups of members of the Department of Chemistry and the Chemical
Research Centre prepared several 25 hour course units for school-teachers
as in-service training modules. These courses were accredited by the
Portuguese authorities and offered with the objective of encouraging a closer
secondary school-university interaction, intended to strengthen links to the
school community. Several new course units are currently being prepared for
introduction in 2010. In 2009, more than 60% of the in-service training within
the Science Faculty took place in the Chemistry Department. At the beginning
of the lective year 2009/10 students were admitted to the first edition of the
new MSc course in further education for school-teachers, formally recognized
by the Portuguese Ministry of Education in June 2009.
Finally, a one-day conference was organized in March to provide chemistry
course students with information about the activity of industrial chemists.
5
Plenary lectures were contributed by guest speakers from food, plastics,
textile industries and by the director of the police forensic laboratory in Oporto.
Part B - E&E group only
Name of group: Electrochemistry and environment (E&E)
Principal investigator: Michael John Smith
Key words (4 only) - Electroanalysis, Electrosynthesis, Functionalizednanomaterials, environmental-impact
B1. Objectives for 2009
This group carries out research in electroanalysis, electrosynthesis and the
application of functionalized materials to the reduction of environmental
impact.
A new method for the evaluation of antioxidant capacity, based on the
scavenging ability of antioxidants towards in situ-generated HO radicals will
be developed. HO reactivity will be optimized in experiments using model
antioxidants. Antioxidant consumption in electrolysis using different charges
will be quantified by chromatographic techniques.
Nickel−catalyzed cyclization provides a convenient alternative to traditional
synthetic methods. This study will develop new methods for cyclization of Dglucose-based substrates in environmentally-friendly media.
New methodologies, catalysts and solvents will be applied to regio-selective
oxidation of carbohydrates. The electro-reactivity of mono and di-saccharides
will be investigated in ionic liquids and TEMPO-mediated carbohydrate
oxidation will be optimized.
Hydrogen and energy production with microbial fuel cells will be studied using
new bacteria and electrode materials.
Novel environmentally-friendly catalysts will be developed using metal
complexes encapsulated/immobilized in nano supports. Materials will be
prepared by biosorption or ion exchange methods and their catalytic activity
evaluated by specific reactions.
New procedures for the synthesis of semiconductors (CdSe, CdS@ZnS and
CdSe@ZnS) will be implemented. Experimental procedures for improved
6
characterization
of
surface
properties
of
funcionalized
carbon-based
nanoparticles will be optimized.
Polymer formulations with improved electrical, mechanical and thermal
properties will be developed using nano-particle structures. ABS stability to
photodegradation by ultraviolet radiation will be optimized using titanium
dioxide and carbon black additives.
Increasing demand for high performance power sources accentuates the
need for solid electrolytes with improved properties. These new electrolytes
may also find application in reactive optical devices or smart labels. The
objective of future research is to contribute to the development of suitable
device components.
Molecular materials with potential application in non-linear optical devices will
be evaluated for specific applications in electronics and signal transmission.
Improvement of energy efficiency and reduction of environmental impact of
certain electronic devices are mid-term objectives.
B2. Main achievements in 2009
During
2009
the
research
carried
out in
the
laboratories
of
the
Electrochemistry and Environment group led to the publication of 19 papers in
international journals. Studies completed in this year have been published in
2010 (8) or accepted for publication (7). The main achievements identified by
group members are indicated in this section.
An electrochemical method for conversion of a D-glucose-based substrate
into substituted tetrahydrofuran has been developed using a nickel (II) catalyst
in non-toxic medium.
Novel
environmentally-friendly
catalysts
were
prepared
using
metal
complexes encapsulated/immobilized in zeolites. The activity of these
materials was evaluated using oxidation reactions in gas and liquid phases.
Nanocomposites of poly(ε-caprolactone) with tungsten trioxide were prepared
by solvent casting using different amounts of nanoparticles.
The photo-oxidative degradation of ABS containing light stabilizers (Tinuvin P
(UVA) and Chimassorb 119 FL (HALS)) under natural and accelerated
weathering conditions was studied in order to enhance performance under
atmospheric conditions.
7
Direct and TEMPO-mediated electro-oxidation of di- and polysaccharides was
investigated in aqueous medium and in ionic liquids.
The effect of bacteria, temperature and pH on energy production from organic
pollutant oxidation in wastewater using microbial fuel cells was determined.
Oxidation potentials of new compounds with potential antioxidant activity were
determined by cyclic voltammetry. Preliminary results provided insight into
structure–activity relationships.
With the aim of developing a method for the evaluation of antioxidant
capacity, different studies were carried out in order to optimize the
electrogeneration conditions of HO. radicals at Pt electrodes and to monitor
the reaction of model antioxidants (gallic and cafeic acids) with HO. radicals
as a means to characterize the scavenging ability of antioxidants.
Various electrolyte formulations based on inter-penetrating and organicinorganic hybrid host networks and different guest salts were prepared and
characterized using thermal and electrochemical methods. Prototype
electrochromic
devices
were
assembled
using
the
most
promising
compositions as multi-functional components in solid-state displays.
New synthetic procedures for the preparation of metal and semiconductor
nanoparticles with controlled dimensions were developed. Functionalization of
carbon-based nanoparticles was shown to improve surface properties.

B7. Organization of conferences
Two members of the Electrochemistry and Environment group participated in the
organization of Hyceltec 2009 (II Iberian Symposium on Hydrogen, Fuel Cells
15
and Advanced Batteries) held in Vila Real (Portugal) between the 13th and the
17th of September, as member of the organizing committee (MMS) and member
of the international committee (MJS).
One of the group members (PP) collaborated in the 8th International Meeting of
the Portuguese Carbohydrate Group (Glupor 8) as a member of the organizing
committee. This conference took place in Braga from the 6th to the 10th of
September.
The one-day meeting “Jornadas de Química” was co-organized by one of the
group members (ICN). The objective of this meeting was to provide students of
various chemistry-related courses with information about the professional and
scientific activity of chemists in industry.
B8. Industrial contract research
One of the members (GB) of the Electrochemistry and Environment group
participated as co-supervisor in collaboration with the Department of Polymer
Engineering (UM) in a jointly funded industrial-academic project. This four-year
project sponsored by a Portuguese company, Poliversal, also involves a Dutch
company, DSM Research, as an external consultant. The objective of this
project is to improve the UV radiation resistance of ABS terpolymers.
During the last year the Portuguese analytical company Vinalia has continued to
collaborate in a project, formalized at the end of 2008. The objective of this
project is to develop new methods using GC-MS and LC-MS instruments,
available in the Centro de Química, for chemical analysis of pesticide content of
wines (PP). This contact led to a further project, carried out by an undergraduate
student on placement, in which experimental conditions for the determination of
heavy metal components and surfactant concentrations in wine samples were
optimized using specific analytical methods (CJS).
A collaborative relationship has been established with a technological interface
company, Simbiente - Environmental Engineering and Management, Ltd. This
company maintains an interest in the development of a microbial fuel cell (PP)
with a view to eventual exploitation of practical commercial devices.
B9. Internationalization (Graduate training networks)
In 2009 the research carried out within the Electrochemistry and Environment
group has resulted in the publication of 17 papers in international journals and
16
the acceptance of a further 15 papers for publication in 2010. The importance of
interdisciplinary and international scientific exchange may be underlined by the
fact that more than 50% of these papers are co-authored with researchers from
other institutions or other scientific disciplines and more than 15% involve
collaboration with foreign institutions. Access to facilities available in other
centres, located within both portuguese and foreign institutions, continues to
provide additional incentives for projects carried out within the centre.
Members of this group also participate in the Cost Action MP0701 (Composites
with novel functional and structural properties by nanoscale materials - Nano
Composite Materials – NCM) and in the Eliare Network SUDOE Project (Health
Theme) (CJS). The main objective of this network is to form a European-wide
scientific and technology knowledge platform on the topic of polymer
nanocomposites. These materials are blends of different polymer matrices with
nanometre sized functional particles. The multi-disciplinary project “Development
of sustainable plant protection” (PP) was also prepared and submitted to the
COST program in 2009 for support. This project is coordinated by Professor
C.Clement (Univ. Rheims, (F)) and the main objective is to combine knowledge
and expertise of plant pathologists and polysaccharide chemists to coordinate
European research devoted to the development of protective ellicitors.
B10. Objectives for future research in 2010
Studies
of
nickel−catalyzed
cyclization
of
different
D-glucose-based
derivatives in environmentally-friendly media will continue. The influence of
experimental conditions will be characterized in order to elucidate the reaction
mechanism.
Metal complexes encapsulated/immobilized in nanostructured supports will be
developed as environmentally-friendly catalysts. Catalytic materials prepared
by biosorption or ion exchange will be evaluated using specific reactions.
Nanocomposites will be developed using polymers with nanostructures for
electronic devices and nanocomposites based on hybrid materials will be
developed to reduce the environmental impact caused by waste packaging.
Polymer formulations with improved electrical, mechanical and thermal
properties will be developed using nano-particle structures. ABS stability to
photodegradation by ultraviolet radiation will be optimized using a combination
17
of UV/light stabilizers and antioxidants in order to understand the UV
degradation mechanism that seems to be different under natural or
accelerated conditions.
The study of TEMPO-mediated electro-oxidation of carbohydrates will be
extended to include new ionic liquids.
The
electroreactivity
of
organic
pollutants
in
aqueous
medium
at
functionalized or non-functionalized carbon nanofibers will be studied.
Oxidation products will be determined by long-term electrolysis.
The power output of microbial fuel cells will be optimized using different cell
configurations.
The evaluation of the antioxidant activity of families of new compounds by
electrochemical methods will be continued. These data will be used to
establish the identity and location of the functional groups that lead to an
increase in antioxidant activity.
The scavenging ability of different classes of antioxidants towards
electrogenerated HO• will be studied. Antioxidants such as polyphenols,
tocopherols and thiols will be tested in order to verify the absence of specific
interactions with the anode material and confirm the involvement of HO• in the
antioxidants oxidation reaction. Experiments to be performed include cyclic
voltammetry, controlled electrolyses and the analysis of electrolyzed
solutions.
Encouraging results have been obtained using host networks with a variety of
chemical compositions and architectures, formulated with different guest salt
combinations. Evaluation of relevant performance parameters of new
formulations will continue and electrochromic displays using the most
promising electrolyte compositions will be assembled and characterized.
Synthesis of various functional nanoparticles including carbon-based
materials, semiconductors (CdSe, CdS@ZnS and CdSe@ZnS), metals (Au
and Ag) and manganite (AaBbMnO3), is being developed. Characterization of
physical and chemical properties will carried out to evaluate potential
applications in optics and life sciences.
B11. Funding source, actual
18
This group of researchers received the sum of 66 000 Euros from the Centre
of Research in Chemistry, through the FCT pluriannual funding program in
2009.
Additional support of a total of approximately 31 430 Euros was
received from projects included in specific FCT-Science research and
technological
development
programs
including
“BIOPACK
-
In-situ
biopolymers nanocomposites: high performance packaging materials for a
clean environment” (AMF and ICN) and “Thienylpyrroles as building blocks on
the synthesis of organic and coordination compounds with nonlinear optical
(NLO)
applications”
(AMF).
The
project
entitled
“Catalisadores
nanoestruturados com nanofibras de carbono para aplicações ambientais”
was funded (6 642 Euros in 2009) through the Capacitation program in
Nanotechnology (PP, ICN and AMF). Twelve on-going FCT-Human
Resources grants to PhD students provided a total of 16 041 Euros.
In February of 2009 members of the group submitted eight projects to the FCT
call for new project proposals. Only one project proposal was financed with a
starting date in 2010. In the second FCT call for proposals (closing date
December) a further five projects were submitted for evaluation.
B12. Funding source, pending
Financial support is expected through continuing PTDC projects (44 721
Euros), the on-going Nanotechnology project (49 350 Euros) and FCT-Human
Resources grants (20 166 Euros). Finally about 1 500 Euros is expected to be
attributed to a group member (CJS) through the Eliare Network SUDOE
Project (Health Theme).
The Electrochemistry and Environment group submitted five projects to the
2009 FCT call for new projects with closing date in December 2009. The
results of these applications for support are still pending.
