Mixed alkali environment in chalcohalide glasses for optical applications
Heavy alkali halide sulphide and selenide glasses are promising hosts for active and passive optical devices. Lithium and sodium chalcohalide glasses exhibit high ionic... -
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... -
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... -
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 study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
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,... -
Structural investigation of biodegradable Mg-based bulk metallic glass
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... -
Investigation of the Negative Thermal Expansion in (Sr,Ca)FeO2 with FeO4 squa...
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... -
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... -
PDF analysis for the local structures of PZT in the morphotropic phase boundary
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.... -
Structural changes in 320GB Blu-ray disc based on BiOx glass
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... -
Understanding the relationship between glass composition and rare earth envir...
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 ¿... -
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... -
Chemical disorder and network structure of glassy As2Te3
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 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...
