Total scattering study of the orientational phase transition in para-terphenyl
There is currently a resurgence of interest in phase transitions in orientationally disordered molecular crystals. This is partly driven by the fact that new experimental and... -

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.... -

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... -
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 study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Dynamical disorder or incipient nano-ferroic distortions in CaSnO3 perovskite?
It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways.... -
The Nature Of Magnesium Substitution in Beta-Tricalcium Phosphate
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... -
The structure and hydrogen bonding of poly(pyridobisimidazole) (PIPD)
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... -
Crystallographic determination of the minting of coins in Tudor Britain : an ...
King Henry VIII's flagship, the Mary Rose, offers a unique insight into Tudor life. As well as her value as one of the first purpose built warships of the modern period,... -
Investigation of the Negative Thermal Expansion in (Sr,Ca)FeO2 with FeO4 squa...
SrFeO2 bears a square planar oxygen coordination around Fe2+. The rarity of this structure led us to study the substitution of strontium by calcium and we obtained the solid... -
Structure of novel silica-free titanate glasses
Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial... -
The structure of hydrogen in calcium-ammonia-graphite: an in situ time resolv...
The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this... -
Local structure and dynamics in metal-imidazolate frameworks
This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and cobalt imidazolate. Imidazole (IM) is a small, flat... -
How molecular solids prepare for phase transitions: The phase transition in o...
Oxalyl chloride, which is a liquid at RT, forms a disordered phase (I) on cooling to 260 K. This phase is unstable with respect to an ordered phase (II) below 250 K, but in... -
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... -
The Calcium Environment in Gallate Glasses
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... -
Polyhedral connectivity in high lead silicate glasses
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...
