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...

The composition dependent structure of glasses in the B2O3-GeO2 system will be measured by employing the method of neutron diffraction with Ge isotope substitution. This system...

The aim of this proposal is a comprehensive structural investigation of a technologically-important perovskite-based ferroelectric material xBiScO3-(1-x)PbTiO3 through studying...

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 aim of the proposed experiment is to measure the changes in crystallographic temperature during beta quenching of Zircalloy 4, an important nuclear fuel cladding material.

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 seek to use the temperature-dependence of the neutron correlation function to investigate the extent of static disorder in glasses and crystals, and also to investigate the...

Long-term nuclear waste repository strategies in Europe include the developing of safe multi-barrier isolation of spent nuclear fuel. One of the considered schemes is the...

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 investigate the effect of glass composition on the environment of rare earth ions doped into chalcogenide glasses. To achieve this the series of glasses, yNd2S3 ¿...

Japanese company TDK has recently developed a 320GB optical storage disc. In contrast to usual DVDs and BDs, the 320GB TDK disc seems to operate because of difference in...

We request four days of GEM time to collect full patterns on PbZr1-xTixO3 (PZT) with different compositions at room temperature for Pair Distribution Functions (PDF) analysis....

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...

SrFeO2 bears a square planar oxygen coordination around Fe2+. The rarity of this structure led us to study the substitution of strontium by calcium and we obtained the solid...

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,...

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...
