Alkali borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4)and [GeOn] (n = 4, 5, 6) polyhedra may all coexist. Equilibrium between these structural units...

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

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...

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...

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...

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

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 objective of this study is to examine the local structure of a set of Iron Silicate glasses containing a single alkali metal in order to understand the correlation of...

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...

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...

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...

Many living organisms have developed mechanisms that protect them from extremeenvironmental stresses such as freezing and pressure. One common mechanism involvesaccumulation of...

We wish to better understand the interaction between the alkaline earth modifiers and the tellurite glass network. The aim is to relate structural changes in the glasses with...

Alkali borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4)and [GeOn] (n = 4, 5, 6) polyhedra can coexist. Equilibrium between these structural units has...

We wish to better understand the evolution of the tellurium environment in glasses with the addition of modifier oxides. The aim is to relate these structural changes to the...

Niobium is one of the candidates for causing strong non-linear optical properties in oxide glasses. Recently, Raman gain experiments on niobium phosphate glasses were quite...

Yttrium doped glasses are of considerable interest due to their potential for use as in-vivo radioactive beta- emitters for localised treatment of liver cancer and other...

This study will investigate the structural effect of adding titanium oxide to a calcium phosphate bioactive glass. We wish to understand the structural origins of the increased...

Bioactive glasses are of considerable interest due to their potential for biomedical applications. In order to model the behaviour and dissolution of these materials it is...
