Total scattering measurement of EMT framework zeolite: does it obey Lowenstei...
Zeolites are meso- and nano-porous framework materials with applications in many industries. The zeolite framework consists of corner-sharing tetrahedral units. The catalytic... -
Uncovering the Structure-Luminesce Relationships for Mn Doped Zinc Phosphate ...
Glass-based phosphors have applications that range from light-emitting diodes to lasers. The optical properties of these materials depend on the coordination environment of the... -
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... -
A Structural Study of Tungsten Tellurite Glasses
Tungsten Tellurites are being used to make optical fibres that transmit light into the mid infra red. However, not much is know about the structure of these glasses. We wish to... -
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... -

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... -
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... -
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... -
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... -
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.... -
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... -
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... -
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...
