Charge carrier relaxation in fluorite-structured oxygen ion conductors /
Zirconia (ZrO2) and ceria (CeO2) based solid oxygen ion conductors are investigated in the dissertation. The electrical properties (impedance and electric conductivity) were studied in broad frequency (from 1 Hz to 10 GHz) range and wide temperature (from ambient to 1150 K) interval by advanced …

The discovery of new functional oxides using combinatorial techniques and advanced data mining algorithms
… is a wide ranging field driven by device applications. For many years, the demand for new materials was addressed largely through serial processing and analysis of samples often similar in composition to those already characterised. The Functional Oxide Discovery project (FOXD) is a combinatorial …

Influence of Electronic Structure and Lattice Dynamics on Oxygen Ion Transport in Solid-State Ionic Conductors
Solid-state oxygen ion conductors are crucial for electrochemical devices such as separation membranes, solid-oxide electrolyzers, fuel cells, and sensors, serving as a technological link between renewable energy generation and consumption. Currently, these conductors are limited by slow transport …
