The acetone - chloroform system is the classic textbook example of a negative-pressure azeotrope, i.e. the vapour pressures of the binary mixtures are lower than expected for...

A combination of high real-space resolution neutron diffraction and 27Al and 29Si NMR experiments will be used to measure the structure of glassy MgO-Al2O3-SiO2. A focus will be...

We seek to use the temperature-dependence of the neutron correlation function to investigate the extent of static disorder in glasses and crystals, and also to investigate the...

Peptidomimetics are synthetic mimics of peptides, the natural building blocks of proteins, and their development is a growing field of science. An underlying theme in recent...

The way that small molecules pack together can have substantial ramifications on the observed physical properties, reactivity, and device characteristics, even if the molecule...

We wish to perform a detailed and comprehensive study of the structure of lead germanate glasses, over a wide range in composition. Most structural studies of germanate glasses...

Crystalline mercury sulphide exists in two drastically different polymorphic forms: red chain-like insulator, alpha-HgS, and black tetrahedral narrow-band semiconductor,...

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...

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...

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...

We request 3 days of beamtime on GEM to attempt to perform neutron diffraction on helium inside vitreous SiO2. Significant amounts of helium can be dissolved into the glass...

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...

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

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

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...

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...

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 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...

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