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...

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...

GeO2-rich potassium borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4) and [GeOn] (n = 4, 5, 6) polyhedra may all coexist. We wish to determine average...

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...

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...

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...

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

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...

Tellurite glasses exhibit strong non-linear properties which are related to the asymmetric environment of the Te atom. The non-linear optical effects are strongest when the Te...

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...

A waste majority of crystals exists in several polymorphic forms in different domains of the P,T-diagram. Liquids and glasses also exhibit polyamorphism and the question remains...

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...

Since local coordination state of lithium cation is important for functional lithium-containing glasses, deep understanding of the structure at atomic and electronic level is a...

We propose to make the first detailed structural study of some polymorphs of gallium oxide that remain poorly characterised and yet have applications in catalysis and are used...
