Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

Materials that show fast oxide ion conduction have potential applications as electrolytes in devices such as solid oxide fuel cells (SOFCs), gas sensors and gas separation...

The perovskite structure with general formula ABX3 describes many hundreds (if not thousands) of materials. Many have interesting and technologically important properties. The...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap andsafe cathodes. Recently, silicate-based cathodes have been described,...

Thermogravimetric analysis on alkaline earth hydrides in St Andrews has revealed a remarkably fast exchange of deuterium and hydrogen by alkaline earth hydrides at relatively...

Gallium oxide is an apparently simple oxide that has been reported to exist as at least 5 polymorphs all of which are stable at room temperature. Structural models, however, for...

The experiment will use neutron diffraction to analyse a hot-rolled matrix of dual-phase ZrNb alloys, in order to measure the macroscopic texture dependence on temperature,...

Increasing global population, global warming and depletion of fossil fuels have resulted in a growing need for better energy storage. Lithium-ion batteries are promising devices...

Oxide ion conductors based on bismuth oxide based have recently been demonstrated as viable alternatives to traditional electrolytes for intermediate temperature solid oxide...

This proposal requests 6 days beamtime on the Polaris diffractometer to study the nature of the local structure within two systems which have been reported to show a solid...

Multiferroics and in particular BiFeO3 have recieved alot of interest. The potential of multiferroic materials to be incorporated into many devices such as sensors and memory...

The structure dependence of BaCe0.8Y0.2O3-d (BCY-20), a leading proton conducting material, will be studied as a function of temperature and, critically, controlled atmosphere...

The orientation of spins in a natural sample of Ti-bearing hematite (Fe2O3) has been measured previously from 2-300K using neutron powder diffraction. It was shown that spins...

The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen...

The future of aviation relies on the improvement of the efficiency of the jet-turbine engines, which is in turn reliant on the properties of the materials (specifically the...

A waste majority of crystals exists in several polymorphic forms in different domains of the P,T-diagram. Liquids and glasses also exhibit polyamorphism and the question remains...

Acceptor-doped perovskite oxides exhibit significant proton conductivity under humid or hydrogen containing atmosphere, which opens a unique possibility to be used as...

During the course of a PhD project funded by CCLRC's CMPC, we have developed a cell that allows electrical transport property measurements to be made simultaneously with the...

In recent years, the research related to agricultural wastes aiming to evaluate their potential for recycling as well as the elimination of the landfills increased dramatically....

This study aims at developing a reliable method for probing heat-induced diagenesis in human bones, by INS spectroscopy. The results thus gathered, coupled to Raman and FTIR...
