The use of fossil fuels as an energy supply becomes increasingly problematic from the point of view of both environmental emissions and energy sustainability. As an alternative,...

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...

As part of an on-going programme of work to better understand critical factors in the methanol-to-hydrocarbon process over ZSM-5 zeolite catalysts, it is becoming increasingly...

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...

Building on a successful programme investigating aspects of iron based Fischer-Tropsch synthesis (FTS) catalysts, it is opportune to extend that work to include Co FTS...

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,...

Recently, several perovskite-like ceramic-oxide solid solutions featuring pseudocubic symmetry have been reported to exhibit technologically promising dielectric and...

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...

Hydrogen selective membranes based on palladium are very important for technological processes such as isotopic separation and gas purification. As a matter of fact, both...

Catalysts used for water-gas shift reactions, and other important industrial processes, often suffer from deposition of hydrocarbon and carbon species (coking) to reduce their...

Palladium is able to dissociative absorb large quantities of hydrogen, reversibly. However, the formation and relative proportion of different phases of palladium hydride, and...

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...
