This proposal is a continuation of a study of molten salts which have a large number of applications, including applications in fuel cells and, in the case of nitrates, as...

Very rapid quenching of liquids to form a glass, from which crystalline phases are subsequently obtained by devitrification, is a powerful technique for obtaining novel...

Ferromagnetic shape memory alloys (FSMAs) are of recent interest because they exhibit a shapememory effect that can be driven by magnetic fields. Thus, FSMAs are important for...

Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or...

The diffusion coefficients of monobranched and dibranched (methyl)hexane and octane in industrially important zeolite ZSM5 will be measured along with their straight chain...

FeRh in the CsCl structure is an interesting material with a tunable magnetostructural phase transition close to, or just above room temperature. On heating through the...

Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9...

Magnetic structures with an out of plane magnetic moment can be found in the latest generation hard disk drive. Interactions between a material with controllable out of plane...

We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks...

Phases in the lithia-alumina-silica phase diagram (LAS) are of great importance owing to the technologically property of ultra-low thermal expansion (ULTE) that they frequently...

Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have...

We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and...

This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and cobalt imidazolate. Imidazole (IM) is a small, flat...

Super proton conductors are in the focus of interest because of their use in low temperature fuel cells. In this project we try to obtain information on proton mobility,...

FeRh exhibits a fascinating structural and magnetic transition from room temperature antiferromagnetism to ferromagnetism at higher temperatures. This complex transition is...

La2O2M2OSe2 (M=Fe, Co, Mn) are layered Mott-insulating antiferromagnets with a potential to be a non-copper high-Tc superconductor. All compounds have shown unusual magnetic...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Perovskite manganates with the general formula L1-xAxMnO3 (e.g. L=La, Pr , Nd and A=Ca and Sr) have attracted significant interest as a result of their unusual transport and...

We wish to trace the changes in lattice parameters and atomic coordinates around the first and second order Curie transitions of Fe2P and boron (11B)-doped Fe2P0.95,B0.05...

Diamonds provide our only direct samples of the very deep Earth and understanding their origin is consequently of great interest to Earth Scientists. The origin of diamonds can...
