Complex oxides within the family CeNbO4 have been shown by single crystal x-ray studies to have superstructured average structures, but little detail has been obtained about the...

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...

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,...

We wish to probe the suggested existence of a high-temperature cubic perovskite phase in the multiferroic material BiFe0.7Mn0.3O3. The parent phase of this material, BiFeO3, was...

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,...

HSLA steels have been widely used in automotive industry to reduce fuel consumption due to its high strength and good weldability. These properties are achieved by nano-size...

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...

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...

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

We request 5 days beamtime on the Polaris diffractometer to perform simultaneous ionic conductivity and neutron powder diffraction measurements of five superionic binary...

Na0.5Bi0.5TiO3 (NBT) based materials can present high level of oxide-ion conduction and therefore they are promising electrolytes for IT-SOFCs. The conductivity of highly...

The dynamics of liquid aluminium will be measured at the structure factor maximum up to twice the melting temperature. We are searching for changes in dynamics which should...

There has been recent interest in the use of cermets based on stabilised delta bismuth oxide based solid electrolytes as cathodes in solid oxide fuel cells. It has been shown...

CuI is well-known to exhibit the superionic behaviour in the high temperature solid state (α-phase), where the mobile Cu ions migrate among the interstices in the f.c.c....
