We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium... -
Thermal expansion of Mg: pre-melting effects in hcp metals and the Earth's in...
Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earths inner core just before... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
Solvent Segregation in Phase-Separated Li-NH3-MeNH2
We request 2 days on MAPS (or 3 days on MARI) to determine the extent of solvent segregation in a liquid-liquid phase-separated metal-amine: The Li-NH3-MeNH2 system. Recently we... -

Structural Aspects and Magnetic Order in Fe based perovskite oxide fluorides ...
In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this... -
Understanding the "post-perovskite" structure (I): the Behaviour of CaPtO3 at...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we...
