FASE Methods• Synthesis• Sample preparation• Structure: XRD• Microstructure: SEM
• Measurements of concentration and transport of defects– Thermogravimetry– Reaction rates– Diffusion– Permeability– Electrical properties
• Electrochemical studies– Fuel cell tests– Electrode kinetics– Photoelectrochemistry
• Further characterization, often in collaboration: – TEM, XPS, SIMS, ND…
• Computational simulations of structure and defects
Examples of current FASE project possibilities
Pulsed Laser Deposited (PLD) films for fuel cells, electrolysers, and gas separation membranes
Proton conducting oxides for fuel cells and electrolysers; measurements and computational approaches
Electrodes for H+-conducting fuel cells and electroysers New proton-electron mixed conductors for gas separation membranes
Water splitting or CO2-to-fuel generation by solid-state photoelectrochemistry
Pure water by photocatalysis – is it possible? Thermoelectric oxides – from heat to electricity Grain boundaries and interfaces; TEM and properties Diffusion and surface kinetics – use of isotopes and ToF-SIMS Nitrogen defects in oxides
Combined computational and experimental studies
and more; depends on what is hot when you start, and your interests…
