1. Properties in New Complex Perovskite-Related Materials, a Matter of Composition and Structure
Sammanfattning : This PhD thesis presents investigations of perovskite-related compounds in systems of interest for applications in components in solid oxide fuel cells. The compound compositions derive from substitutions in the parent compounds LaCoO3, LaCrO3 and SrFeO3. LÄS MER
2. Structure and Properties Investigations of the La2Co1+z(Ti1-xMgx)1-zO6 Perovskite System
Sammanfattning : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0 x 0.9 and z = 0.0, 0. LÄS MER
3. Structural Studies of Mn-X (X=Al, Bi): Permanent Magnetic Materials without Rare Earth Metals
Sammanfattning : How to generate and use electricity in a more efficient way is a major challenge for humankind. In this context, permanent magnets play an important role within a very broad range of electric power applications. The strongest magnets used today are mainly based on alloys that contain rare-earth metals, which are neither economical nor sustainable. LÄS MER
