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. Microstructural evolution of thin epitaxial Perovskite films
Sammanfattning : .... LÄS MER
3. A TEM investigation of adhesion between nanoparticles
Sammanfattning : .... LÄS MER
4. Studies of phases structurally related to hexagonal tungsten bronze in the system ATO₃ - WO₃ (A = K, Rb, Cs; T = V, Nb, Ta)
Sammanfattning : The oxidized analogues (bronzoids) of tungsten bronzes in the systems dTO^-WO^ with A = K, Rb, Cs; T = Ti, V, Nb, Ta and A/W < 1 are reviewed with emphasis on the K-Nb and Cs-Nb systems. The different phases observed in these systems are isostructural with intergrowth tungsten bronze (ITB), hexagonal tungsten bronze (HTB), tetragonal tungsten bronze (TTB) and pyrochlore. LÄS MER
5. A TEM Investigation of Contact between Nanoparticles
Sammanfattning : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. LÄS MER
