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... -
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;... -
PDF study of the effect of synthesis conditions on the local structure of har...
Hard carbons are amongst the most promising anode materials for sodium-ion batteries, but their charge storage mechanisms are still poorly understood. Difficulties in... -
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... -
Effect of Composition on Local Environment of Sulphate in Silicate Glasses
We will study the effects of changes in composition and structure of alkali silicate and alkali-alkaline earth silicate glasses on its sulphate incorporation capacities. Total... -
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... -
Local structure of a barocaloric framework material
Barocaloric materials, in which a large isothermal entropy change is associated with a pressure-induced phase transition, offer an alternative to vapour-compression techniques... -
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... -
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... -
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... -
Investigation of the phases formed during the conversion reaction of the C-ba...
FeF2 is a conversion reaction material that undergoes a reaction with lithium: FeF2+2Li++2e-<->2LiF+Fe, which results in a high theoretical capacity, 571 mA/g.... -
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... -

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... -
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... -
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... -
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... -
Search for the Structural Origin of the Intermediate Phase
The object of this experiment is to search for the structural origin of the intermediate phase by making careful measurements of the structure of glassy Ge-Se which is a... -
PDF Analysis of a new oxide ion conductor
Preliminary investigations have shown that Sr1.8Na0.2MgSi2O7-d, belonging to the melilite family of oxide, is a potential new oxide ion conductor. The aim of this experiment is... -
Structural aspects of conductivity behaviour in transition metal phosphate gl...
Phosphate glasses containing transition metal oxides, such as MoO3 and WO3, are of interest for various applications making use of their electrical properties. MoO3 and WO3 are...
