We request GEM beamtime to study the structure of a series of calcium germanate glasses. The changes in coordination number and properties which occur in alkali germanate...

Tungsten Tellurites are being used to make optical fibres that transmit light into the mid infra red. However, not much is know about the structure of these glasses. We wish to...

We wish to perform neutron diffraction measurements on glass samples of SiO2 and 30CaO.70SiO2 containing both natural oxygen and 18O. The oxygen scattering lengths are almost...

Glass-based phosphors have applications that range from light-emitting diodes to lasers. The optical properties of these materials depend on the coordination environment of the...

Zeolites are meso- and nano-porous framework materials with applications in many industries. The zeolite framework consists of corner-sharing tetrahedral units. The catalytic...

We intend to use neutron diffraction and x-ray diffraction to investigate the structure of potassium and barium iron phosphate glasses, which are potential candidate systems for...

Glass is an essential material with applications that are dominated by oxides, but fluoride glasses (based on barium zirconium fluorides, "ZBLAN" glasses) have key applications...

A range of novel chlorine-containing bioactive glasses have recently been developed at Queen Mary University of London for dental and orthopaedic applications. At present little...

We are about to submit a detailed pair distribution function study of a new lead-free ferroelectric material based on RMC analysis. This method will be applied in VT studies of...

We designed and synthesized a series of new oxided ionic conductors Ba3M1+xTi1-xO8+x (M = Mo and W), which adopt a hybridized structure with the features of 9R perovskite...

The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural...

The average and local structure in the mixed-metal cyanides, Ni1/2Pt1/2(CN)2, Ni1/2Pd1/2(CN)2 and Pd1/2Pt1/2(CN)2 will be determined to give the M-C and M-N bond lengths, the...

The UK nuclear industry is involved in a large effort to decommission nuclear power reactors and safely store radioactive waste. A key process is the vitrification of high level...

Caesium-137 is among the most important hazards associated with low-level nuclear waste. Among the most promising materials for scavenging Cs+ ions from waste solutions are the...

Tin phosphate glasses are an alternative as lead-free glasses with zero photoelastic constant (PEC) for fiber applications. A second modifier oxide is added for improving the...

The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with...

We request beamtime to study lithium silicate glasses over a very wide composition range from 20 to 65 mol.% Li2O, made by rapid quenching. For the higher Li2O contents, the...

A clear description of the local atomic structure as a function of the composition is essential to guide discovery and development of new metallic glasses. The efficient cluster...

Lithium batteries provide the highest energy density which makes them ideal candidates for future generations of portable electronics and electric vehicles. The increasing...

We propose to study a range of novel fluorine-containing bioactive glasses with potential applications in dentistry and orthopaedics. At present little is known about the atomic...
