Titanium silicates are important for a number of applications such as ultra low expansion glasses, anti-reflective thin film coatings and catalytic materials. Titanium silicates...

The aim of this proposal is to examine the relative population of sp2 and sp3 bonds in a small number of graphitic samples, given that the bond length is 1.42A for standard sp2...

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...

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...

We have a continuing interest in the structural role of lone-pair cations in glasses. Thallium oxide behaves unusually in borate glasses, not only in terms of its own...

PxSe1-x glasses cover almost entire composition range from pure Se to P0.84Se0.16. In addition, red phosphorus is usually also amorphous. The P4Se3 cage compound, situated in...

Sol-gel derived calcium silicates are of great importance due to their ability to bond to bone and stimulate new bone growth. Diffraction has revealed the atomic-scale changes...

We have a long-established interest in the structural role of heavy-metal, lone-pair cations such as Pb in glasses. PbO can be incorporated to very high concentrations in oxide...

Our aim is to provide new data concerning the evolution of amorphous gel phases into crystalline inorganic materials to allow information about crystallisation mechanism of...

The environment of calcium in glasses is of widespread interest, and there has been a number of structural studies of calcium aluminate glasses. However, the experimental data...

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...

Our objective is to determine new structural information about the structure of amorphous silicate gels formed early in the synthesis of crystalline, microporous zeolites. This...

It is well known that Ni-Zr amorphous alloys are highly resistant to pulverization due to the repetition of the hydrogen absorption and desorption unlike Ni-Zr crystalline...

Our aim is to examine the structures of disordered gel precursors to nanoporous zeolites that are formed in the early stages of hydrothermal reactions. They are considered to be...

Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial...

PIPD is a polymer with unusual tensile and compressive strength. Inter and intramolecular H-bonding interactions are thought to be responsible for these properties. PIPD is also...

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...

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...

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...
