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... -
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... -
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... -
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... -
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... -
A systematic survey of solute-solute contacts in bulk metallic glasses
A clear description of the local atomic structure as a function of the composition is essential to guide discovery and development of new metallic glasses. The efficient cluster... -
Structural Models of the Polymorphs of Gallium Oxide
Gallium oxide is an apparently simple oxide that has been reported to exist as at least 5 polymorphs all of which are stable at room temperature. Structural models, however, for... -
Metastable phase formation and memory effects in barium borate glasses.
BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates... -
Structures of Gel Precursors of Nanoporous Materials
Nanoporous zeolites are well-known materials with huge industrial and commercial application in important areas yet their crystallisation mechanism remains under great debate....
