The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural... -
Investigating the structure of novel chloride-containing bioactive glasses fo...
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... -
Breaking Zachariasen rules - the structure of barium zirconium fluoride glasses
Glass is an essential material with applications that are dominated by oxides, but fluoride glasses (based on barium zirconium fluorides, "ZBLAN" glasses) have key applications... -
Structural studies of modified iron phosphate glasses to understand key struc...
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... -
Isotopic Mass Contrast Study of Silica Glass
We wish to perform neutron diffraction measurements on glass samples of SiO2 and 30CaO.70SiO2 containing both natural oxygen and 18O. The oxygen scattering lengths are almost... -
The Structure of Alkaline Earth Germanate Glasses
We request GEM beamtime to study the structure of a series of calcium germanate glasses. The changes in coordination number and properties which occur in alkali germanate... -

A Structural Study of Alkaline-Earth Tellurite Glasses.
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... -
Evaluation of inelasticity effects in diffraction
For total diffraction measurements using neutrons it is important to correct the data for inelasticity effects, especially for samples containing light atoms. Conventionally... -
Null Isotope Study of Lithium Borogermanate Glasses - continuation
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... -
Developing a model for tellurium coordination change in glasses
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... -
Structural Studies of Complex Mixed-Metal Pyrochlore and Spinel Oxides
Our objective is to determine structural models for some complex, mixed-metal oxide phases that are as complete as possible using analysis of PDFs produced from total neutron... -
A structural study of titanium tellurite glasses
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... -
Structure of niobium phosphate glasses
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... -
Mercury sulphide dimorphism in liquids and glasses
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... -
The Nature Of Zinc 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... -
Test experiment: Neutron diffraction on helium in silica
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... -
Structure-Property Relationships in Polymorphs of Mn(CN)2
We will determine the atomic and magnetic structure of two polymorphs of manganese cyanide, Mn(CN)2, which exhibit negative thermal expansion (NTE). The two forms are related;... -
Long-Range and Local Structures of New Pyrochlores and Fluorites
We propose to study by total neutron scattering the structures of some complex oxide materials prepared by new hydrothermal routes in order to construct structural models...
