Metal Halide Induced Chemical Disorder in Chalcogenide Glasses
Chalcogenide glasses containing light alkali and Group 11 (Cu, Ag) halides MY (Y = Cl, Br, I) exhibit high ionic conductivity while their heavy alkali counterparts show... -
Cation environments in lead-free glasses
BaO+ZnO containing glasses are being studied as an alternative to lead-based glasses because they exhibit excellent dielectric, thermal, optical and crystallisation properties.... -
Atomic structure of ternary tin phosphate glasses
Tin phosphate glasses are the alternative as lead-free glasses with zero photoeleastic constant (PEC) for fibers that are used in sensors of electric current. Since the binary... -
Structures of New Oxides from Total Scattering
Our objective is to determine accurate structural models for some novel oxide materials that we have recently prepared using new synthesis approaches, each of which is formed as... -
Cation environment and the tellurite anomaly
We have recently shown that the anomalous behaviour of the Te-O coordination number, nTeO, for binary tellurite glasses is related to the presence of terminal Te=O bonds in... -
Refining compositions for bio-active phosphate glasses
We wish to investigate the structural changes which arise when B2O3 is added to a bioactive phosphate glass. We are particularly interested to study the phosphate environment... -
Disorder in substituted beta-tricalcium phosphate for waste immobilisation
We have a long established interest in the materials used for the immobilisation of nuclear waste from the domestic power industry and legacy waste from various defence... -
Structural behaviour of zinc in low phosphate content glasses for bone cements
Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate... -
The Structure of Lead Tungstate-Phosphate Glasses
Lead tungstate phosphate glasses are of practical interest due to their electrochromic and photochromic properties, with a wide range of practical applications in smart windows,... -

We have a long established interest in the materials used for the immobilisation of nuclear waste from the domestic power industry and legacy waste from various defence... -
Structural investigation of biodegradable Mg-based bulk metallic glass
Mg-Zn-Ca glasses show considerable promise for use as medical implants. Magnesium, zinc and calcium are all elements found within the human body, and the biocompatibility of... -
Structural behaviour of gallium in phosphate glasses for bone cements
Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate... -

We wish to study a series of glasses of composition As2Ch3 (Ch = S, Se and Te) to investigate the effect of varying the chalcogen type on the non-linear optical (NLO) behaviour... -
Neutron diffraction of amorphous FePO4 and LiFePO4
We are convinced that a careful study of the atomic structure of a-FePO4 would provide very interesting insights into several phosphate systems, including phosphate glass... -
Structural Studies of High Level Waste Glass
The aim of this proposal is to develop a methodology to investigate multicomponent glass structure, combining neutron diffraction, XRD, NMR, ab initio MD, and RMC. We wish to... -
The effect of combined modifiers: understanding the interactions between alka...
The mixed alkali effect is a well-known phenomenon whereby combining two alkalis in a ternary glass system can produce physical properties which can be superior to, but cannot... -
Chemical disorder and network structure of glassy As2Te3
Telluride glassy systems are widely used for phase-change optical recording. They are also promising materials for far-IR applications. The atomic structure of telluride glasses... -
The structural role of carbonate groups in glass
We request GEM beamtime to study the structure of samples of sodium silicate glass with and without CO3 carbonate groups. The presence of CO3 carbonate groups in the glasses is... -
Structural role of magnesium in aluminosilicate glass
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... -
Short range static and thermal disorder in glasses and crystals
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...
