4 Project Idea Pilot lines for manufacturing of materials with customized thermal/electrical conductivity properties Topic identifier: PILOTS Publication date: Types of action: IA Innovation action DeadlineModel: two-stage Deadline: :00:00 Opening date: nd stage Deadline: :00:00 Challenge: The need for such materials, affordable, industrially robust and environmental friendly, calls for the upscaling of these widely researched materials and their manufacturing processes. This should ensure the further integration of the nanoenabled multifunctional materials into practical large-scale applications, and drastically exceed the current use in niche-markets. Activities are expected to focus on Technology Readiness Levels 4 to 6, and target Technology Readiness Level 7. ics/2362-pilots html Huelser huelser@iuta.de 4

8 Materials List Oxides TiO 2 Specific Iron oxides SiO 2 ZnO Non- Oxides & Composites Si, doped and un-doped C, SiC Si doped SiO 2 (Si Quantum dots) Si / Ge FeSi 2 Core Shell Systems (Fe@Fe 2 O 3 ) Fe 2 O 3 Fe 3 O nm Si- Nanoparticles Huelser huelser@iuta.de 8

9 Application fields I. Fuel cells: Develop electrodes with long-term stability with low precious metal load by better understanding aging mechanisms II. Catalysts for energy technology: Develop immobilized, functional nanoparticles for photo-catalytic water dissociation, improving photo-catalysis III. Battery technology: Develop anode materials with high storage capacity of >1500 mah/g based on Si / C nanocomposites IV. Photovoltaics: Reduce the number of process steps and processing temperature of Si-based photovoltaics using highly doped Si nanoparticles and laser sintering V. Thermoelectric generators: Silicon based thermoelectric generator made in collaboration of IUTA, NST, SLV (Duisburg) Develop thermoelectric materials based on Si and SiX nanocomposites. Unlike the Pb, Te, and Sb compounds typically used so far, Si-based systems are non-toxic and uses abundant raw materials Huelser huelser@iuta.de 9
