Cation environments in lead-free glasses
BaO+ZnO containing glasses are being studied as an alternative to lead-based glasses because they exhibit excellent dielectric, thermal, optical and crystallisation properties.... -
Atomic structure of ternary tin phosphate glasses
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... -
Structures of New Oxides from Total Scattering
Our objective is to determine accurate structural models for some novel oxide materials that we have recently prepared using new synthesis approaches, each of which is formed as... -
Structure of a clathrate hydrate inhibitor in water
Gas hydrates (crystalline inclusion compounds of water and small hydrocarbons) present a very real challenge to the petrochemical industry. In uninhibited systems gas hydrates... -
Cation environment and the tellurite anomaly
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... -
Refining compositions for bio-active phosphate glasses
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... -
Disorder in substituted beta-tricalcium phosphate for waste immobilisation
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... -
Structural behaviour of zinc in low phosphate content glasses for bone cements
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... -
The Structure of Lead Tungstate-Phosphate Glasses
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,... -
Investigating the structure of novel zinc and magnesium doped bioactive glasses
A range of novel bioactive glasses containing zinc and magnesium have recently been developed for dental and orthopaedic applications. At present little is known about the... -
The Nature Of Magnesium Substitution in Beta-Tricalcium Phosphate
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... -
Structural behaviour of gallium in phosphate glasses for bone cements
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... -
As2Ch3 glasses: Understanding the relationship between glass structure and no...
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... -
Structural Studies of High Level Waste 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 effect of combined modifiers: understanding the interactions between alka...
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 structural role of carbonate groups in glass
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... -
The microscopic structure of the acetone - chloroform azeotrope
The acetone - chloroform system is the classic textbook example of a negative-pressure azeotrope, i.e. the vapour pressures of the binary mixtures are lower than expected for... -
Structural role of magnesium in aluminosilicate glass
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... -
Monitoring Packing Changes in Magnetic Halogenated Phthalocyanine Molecules
The way that small molecules pack together can have substantial ramifications on the observed physical properties, reactivity, and device characteristics, even if the molecule... -
