We have a continuing interest in the structural role of lone-pair cations in glasses. Thallium oxide behaves unusually in borate glasses, not only in terms of its own...

We wish to perform a detailed and comprehensive study of the structure of lead germanate glasses, over a wide range in composition. Most structural studies of germanate glasses...

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...

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...

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...

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...
