description

The main thematics of this strand are 'Energy Materials', 'Functional Coatings' and 'Carbon Materials and Composites'.

1) ENERGY MATERIALS
This axis is directed to energy conversion, mainly by fuel cells and other electrochemical systems, within the guidelines
of increasing use of renewable energies, non-combustion conversion of fossil fuels, and carbon-lean energy
conversion.

  • 'Solid oxide cell materials and concepts': this is focused on design, processing and assessment of materials for different components of solid oxide cells (electrolytes, fuel electrodes, oxygen electrodes and interconnectors). Their assessment is based on requirements of fuel cells and/or electrolysers, and other high temperature electrochemical cells (sensors, pumps…), with emphasis on harsh operation conditions.
  • 'Materials for other fuel cell concepts': these developments are intended for proton exchange and alkaline polymer membrane fuel cells. The emphasis is on materials with enhanced tolerance to higher temperatures, renewable bio-based materials (bacterial cellulose), and nano-ionics;
  • 'Oxygen technologies': though previous studies were focused mainly on mixed conducting membranes for conversion of hydrocarbons to syngas and oxygen separation, new development are focused on materials with high oxygen storage ability and their processing as porous monoliths for relevant applications, such as conversion of hydrocarbons to syngas by chemical looping;
  • 'CO2 technologies': this is mainly based on membrane for selective CO2 separation, with emphasis on oxide-molten carbonate composites;
  • 'Carbon lean technologies': the main focus is on production of metals and alloys by direct electroreduction of oxides in alkaline conditions or molten electrolytes;
  • 'Heat conversion and storage': this is focused on enhanced use of waste heat or natural heat sources, by heat or cold storage, to bridge time gaps between availability and consumption, and prospective thermoelectric conversion;
  • 'Solar energy conversion': this sub-axis is already seeking novel materials for photovoltaics, and will be extended to photoelectrochemical or photocatalytic conversion of solar energy.

2) FUNCTIONAL COATINGS

  • 'Nanocontainers': this sub-axis is focused on 'smart' nanocontainers for functional coatings;
  • 'Active protective coatings': this is based on enhanced protection by active coatings based on novel concepts of multi-level self-healing;
  • 'Surface treatments': a variety of surface treatments are applied on different substrates with special focus on hybrid multi-material structures;
  • 'Designed functionalities': different functionalities such as impact or corrosion detection, antibiofouling, etc., are tailored and integrated on self-healing coatings and active layers on non-metallic substrates;
  • 'Self healing mechanisms": this is focused on the mechanisms of self-healing at different scales (nano-/micro-/macro).

3) CARBON MATERIALS AND COMPOSITES

  • 'CVD synthesis': processing of nanostructured carbon allotropes (carbon nanotubes, nanofibers, graphene);
  • 'Nanodiamond coatings': coatings for highly wear resistant (bio)tribosystems and diamond-based ultramicroelectrodes as function devices (e.g., biosensors) and to monitor corrosion for enhanced protection;
  • 'Carbon nanotubes and graphene': atomic layer deposition is the basis for processing functional inorganic compounds (ZnO, MnO2, TiO2, Fe2O3, WS2, h-BN…) based on nanostructured carbon templates (nanotubes, graphene,…);these materials are tailored for a variety of functionaties, including photovoltaics, catalysis, dielectrics, radiation detection and nanotribology, and within different fields (biomedicine, instrumentation, solar energy, oil and chemical industries).

 

general aims

1) ENERGY MATERIALS

  • 'Solid oxide cell materials and concepts': development of materials for solid oxide cells, from single phase to heterostructured electrolytes, fuel electrodes, oxygen electrodes and interconnectors, based on improved understanding of structure/property and microstructure/property relationships. Though these materials developments are primarily focused on fuel cells (SOFC), one also seeks assessment in electrolyser (SOEC) or reversible SOFC/SOEC mode. Other studies seek enhanced tolerance of high temperature electrochemical cells (sensors and pumps, etc.) for unconventional or harsh operating conditions (e.g. molten media);
  • 'Materials for other fuel cell concepts': exploitation of novel materials for proton exchange and alkaline polymer membrane fuel cells, with emphasis on renewable bio-based materials such as bacterial cellulose, and concepts of nano-ionics;
  • 'Oxygen technologies': these concepts are intended for oxygen separation or selective partial oxidation based on mixed conducting membranes, and applications of oxygen storage materials for chemical looping or thermochemical redox processes (e.g. water splitting);
  • 'CO2 technologies': novel membrane concepts for selective CO2 separation, such as mixed conducting oxide-molten carbonate composites;
  • 'Carbon lean technologies': development of alternative carbon lean technologies to replace classical carbon intensive processing, with emphasis on direct electroreduction of oxides and high temperature electrolytic processes in molten salts or molten glasses;
  • 'Heat conversion and storage': oxide thermoelectrics for conversion of waste heat or natural heat sources, and phase change materials for heat/cold storage;
  • 'Solar energy conversion': this is focused on materials for photovoltaics and will be extended to other concepts of solar energy conversion (photoelectrochemical or photocatalytic).
