11. Radium sulphate and its co-precipitation behaviour with barium and strontium
Sammanfattning : .... LÄS MER
12. Neutron scattering investigations of proton dynamics in acceptor doped barium zirconates
Sammanfattning : Hydrogen fuel cells represent one of the most promising sustainable technologies for energy conversion. The advantages of the combination of a solid state electrolyteand low operational temperatures (... LÄS MER
13. 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
14. Significance of grain boundaries for transport phenomena in graphene and proton-conducting barium zirconate
Sammanfattning : Grain boundaries can have a significant influence on the properties of polycrystalline materials. When determining the type and extent of this influence it is frequently useful to employ computational methods such as density functional theory and molecular dynamics, which can provide models of the grain boundary structure at the atomistic level.
