1. Proton conductivity in acceptor-doped lanthanide based pyrochlore oxides
Sammanfattning : A high interest in developing new materials for SOFC applications in the temperature range of approximately 200–500 C has been growing lately. The lower activation energies for proton (H+) mobility can give higher conductivity in this temperature range. LÄS MER
2. Point defects and ion conduction in solid oxides: a first-principles case study of La2Zr2O7
Sammanfattning : In the endeavor to attain a clean environment and sustainable energy consumption, the notion of a future hydrogen economy stands out as one of the grandest visions. Striving for this vision, a critical task lies in optimizing the performance of the fuel-cell devices responsible for extracting electric power from the energy stored in hydrogen molecules. LÄS MER
3. Inelastic light scattering study of strongly correlated oxides
Sammanfattning : .... LÄS MER
4. Inelastic light scattering of superconducting transition metal oxides
Sammanfattning : .... LÄS MER
5. Proton conductivity of lanthanum and barium zirconate: Microscale aspects on first-principles basis
Sammanfattning : Fuel cells are devices which convert chemical energy into electrical energy cleanly and efficiently. Development of fuel cells compatible with hydrocarbon fuels would make more efficient use of present fossil and renewable fuels, and also enable progress towards a future hydrogen economy. LÄS MER
