Hydrodynamic finite-size scaling of the thermal conductivity in glasses
In the past few years, the theory of thermal transport in amorphous solids has been substantially extended beyond the Allen-Feldman model. The resulting formulation, based on... -
Kinetic study of nucleation, phase formation and transformations in bioactive...
We aim to study the kinetics of phase formation and transformation during the crystallisation of apatite from amorphous degradable bioactive glasses used as a treatment for... -
The Structure of Lead Phosphomolybdate Glasses
Molybdenum containing glasses have many potential applications. However, there is little information available on the structural role of molybdenum in glasses, and the limited... -
The structural role of zinc in complex phosphate glasses for new bone cements
A study of zinc containing phosphate glasses for biomedical applications is proposed. The structural role of zinc as a function of composition will be investigated through... -
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... -
Polyhedra Coexistence in Alkali Borogermanate Glasses
GeO2-rich potassium borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4) and [GeOn] (n = 4, 5, 6) polyhedra may all coexist. We wish to determine average... -

Neutron diffraction of sodium iron phosphate glasses
One important structural application of oxide glasses is for nuclear waste immobilisation. Recent reports have highlighted the possibility of iron phosphate glasses as an... -
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... -
The environment of lithium in an invert glass
We request beamtime to study lithium silicate glasses over a very wide composition range from 20 to 65 mol.% Li2O, made by rapid quenching. For the higher Li2O contents, the... -
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... -
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... -

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... -
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... -
Structural studies of bioactive yttrium doped alumino-silicate glasses.
Yttrium doped glasses are of considerable interest due to their potential for use as in-vivo radioactive beta- emitters for localised treatment of liver cancer and other... -
High frequency optic-like mode and vibrational density of states in ionic liq...
We propose a comparative study of the high-frequency optic-like mode and Boson peak modes observed in the vibrational density of states (DOS) in the glass phase of the two model... -
