1. Neutron spectroscopy and computational studies of hydride-ion dynamics in oxide- and nitride-hydride materials
Sammanfattning : This thesis presents studies of the hydride-ion dynamics in the nitride- and oxidehydride materials Ca3CrN3H and BaTiO3-xHx (with x < 0.2). LÄS MER
2. Dynamical properties of metal halide and oxyhydride perovskites
Sammanfattning : This thesis concerns investigations on the dynamical properties of two classes of energy-relevant materials, namely metal halide and oxyhydride perovskites, using neutron scattering techniques. These two classes of materials share the same aspect of a perovskite-type crystal structure but are different in terms of their functional properties and concomitant promise for various technological applications.

3. On the defective origin of conductive and structural properties of oxides: insights from first principles
Sammanfattning : Oxides are versatile materials with applications in many different research fields; especially those related to clean energy technologies, such as fuel cells, batteries and solar panels. Many functional properties of these materials derive from lattice imperfections, or defects, and a lot of effort has been put into fine tuning these materials by modifying their structure on the atomic scale.

4. Local structure and dynamics of proton and hydride-ion conducting perovskite type oxides
Sammanfattning : Proton and hydride-ion conducting oxides show potential for application in several technological devices, such as solid oxide fuel cells and batteries. However, fundamental properties pertaining to the local structure and conduction mechanisms in these materials are unclear. LÄS MER
5. Structural Basis for Hydrogen Interaction in Selected Metal Hydrides
Sammanfattning : Metal hydrides have existing and potential uses in many applications such as in batteries, for hydrogen storage and for heat storage. New metal hydrides and a better understanding of the behaviour of known metal hydrides may prove crucial in the realisation or further development of these applications. LÄS MER
