Tin phosphate glasses are the alternative as lead-free glasses with zero photoeleastic constant (PEC) for fibers that are used in sensors of electric current. Since the binary...

We have recently shown that the anomalous behaviour of the Te-O coordination number, nTeO, for binary tellurite glasses is related to the presence of terminal Te=O bonds in...

We wish to investigate the structural changes which arise when B2O3 is added to a bioactive phosphate glass. We are particularly interested to study the phosphate environment...

Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate...

Lead tungstate phosphate glasses are of practical interest due to their electrochromic and photochromic properties, with a wide range of practical applications in smart windows,...

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...

Mg-Zn-Ca glasses show considerable promise for use as medical implants. Magnesium, zinc and calcium are all elements found within the human body, and the biocompatibility of...

Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate...

We are convinced that a careful study of the atomic structure of a-FePO4 would provide very interesting insights into several phosphate systems, including phosphate glass...

The aim of this proposal is to develop a methodology to investigate multicomponent glass structure, combining neutron diffraction, XRD, NMR, ab initio MD, and RMC. We wish to...

The mixed alkali effect is a well-known phenomenon whereby combining two alkalis in a ternary glass system can produce physical properties which can be superior to, but cannot...

A combination of high real-space resolution neutron diffraction and 27Al and 29Si NMR experiments will be used to measure the structure of glassy MgO-Al2O3-SiO2. A focus will be...

The way that small molecules pack together can have substantial ramifications on the observed physical properties, reactivity, and device characteristics, even if the molecule...

We will investigate the structural origin of the high sulphate solubility of Ba-rich silicate glasses with radioactive waste immobilisation applications by measuring total...

Since local coordination state of lithium cation is important for functional lithium-containing glasses, deep understanding of the structure at atomic and electronic level is a...

This study will investigate the structural effect of adding titanium oxide to a calcium phosphate bioactive glass. We wish to understand the structural origins of the increased...

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...

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...

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...

Glass is an essential material with applications that are dominated by oxides, but fluoride glasses (based on barium zirconium fluorides, "ZBLAN" glasses) have key applications...
