We wish to exploit the contrast afforded by neutrons to study the ordering of In and Sn cations in indium tin chalcogenides. Cation ordering has been inferred from spectroscopic...

MV2O6 brannerites have a network structure in which chains of edge-sharing MO6 octahedra result in 1-dimensional magnetic properties. A recent study reported monoclinic CoV2O6...

The mechanical properties of of austenitic stainless steels are thought to be improved by the phenomenon of deformation-induced martensitic transformation, which acts to...

We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....

One method by which the efficiency of gas turbine engines may be improved is by increasing the gas stream temperature on entry to the turbine. Currently this temperature is...

Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of...

The intermetallic compound, Re3W is a non-centrosymmetric system with large atomic number (Z) for both constituents (75 for Re and 74 for W) and hence is a good candidate for...

We are investigating the ultra-rapid synthesis of transition metal carbides using microwave (MW) irradiation. Currently we are establishing an understanding of these reactions...

This proposal seeks to determine the structures of the high temperature phases of SrNdNiRuO6 and to investigate the nature of the transitions between them. Iturbe-Zabalo et al....

FeF2 is a conversion reaction material that undergoes a reaction with lithium: FeF2+2Li++2e-<->2LiF+Fe, which results in a high theoretical capacity, 571 mA/g....

The structures of emulsions formed from mixed oil-soluble and water-soluble amphiphiles (respectively derivatives of polyisobutylene, PIBSA, and polyacrylamide, PAM) will be...

Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal...

There is a great interest in the last years in the study of Mg-Y-Zn alloys containing LPSO phases. This kind of alloys behaves as a metal matrix composite where the LPSO phase...

The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low...

Plastic phases are characterized by a positional ordering of the molecular centers of mass while molecules are rotating in a hindered way. Therefore these phases are...

The topotactic reduction of Sr3Co2O5Cl2 and Sr3Co2O5.80 yields the Co(II) phases Sr3Co2O4Cl2 and Sr3Co2O5 respectively. These phases contain corner linked arrays of...

Apatite-type lanthanide silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors. The presence of interstitial oxide ions is...

In this proposal we wish to continue our current work on mesostructured inorganic films in largely ethanolic solutions, containing limited amounts of water. Transition metal...

We propose to use SXD for mapping the crystallographic phases in an extended 3D benchmark object. The phase distribution will be reconstructed using a geometrical aberration...

In the piezoelectric ceramic material PbZrxTi1-xO3 (PZT) there is controversy about the structure of PZT at the Zr-rich end. This region has always been considered to be of...
