The structure of the phosphate materials Na_{1+x}Ge_{2-x}Al_x(PO_4)_3 with x = 0, 0.4 and 0.8 will be investigated using high real-space resolution neutron diffraction. In the...

The accurate determination of the defect structure of rare earth (RE) doped ceria solid electrolytes is fundamental for the comprehension of oxygen diffusion and charge...

Molybdenum containing glasses have many potential applications. However, there is little information available on the structural role of molybdenum in glasses, and the limited...

A study of zinc containing phosphate glasses for biomedical applications is proposed. The structural role of zinc as a function of composition will be investigated through...

BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates...

The diffuse and intermittent nature of renewable power sources such as wind and solar presents problems regarding how best to harvest the energy they produce and store it for...

White rust (WR) is a highly reactive material that acts as a precursor in many chemical processes. It is produced during iron corrosion and has been implicated as a key reactive...

After an almost forty year lull in research on multiferroic materials, there has been a resurgence of interest in them. However, it is particularly challenging to synthesize a...

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...

We will study the origins of the solubility of problematic anionic species (sulphate and chloride) in borosilicate glasses representative of real-world radioactive waste...

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...

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...

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...

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...

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...

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...

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 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...

For total diffraction measurements using neutrons it is important to correct the data for inelasticity effects, especially for samples containing light atoms. Conventionally...
