Additions of a small amount of alumina to bioactive phosphate-based glass significantly improves the formation of the hydroxycarbonate apatite layer on the surface when exposed...

We have a long-established interest in the structural role of heavy-metal, lone-pair cations such as Pb in glasses. PbO can be incorporated to very high concentrations in oxide...

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

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...

We request GEM beamtime to study the structure of samples of sodium silicate glass with and without CO3 carbonate groups. The presence of CO3 carbonate groups in the glasses is...

Telluride glassy systems are widely used for phase-change optical recording. They are also promising materials for far-IR applications. The atomic structure of telluride glasses...

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...

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...

We wish to study a series of glasses of composition As2Ch3 (Ch = S, Se and Te) to investigate the effect of varying the chalcogen type on the non-linear optical (NLO) behaviour...

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...

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 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...

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...

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...
