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,...

As part of an ongoing effort to understand the underlying physics of MOFs, we propose to study the local structure and dynamics in two quartz-like systems: indium deuterium...

Lithium (LiPO3) and sodium (NaPO3) metaphosphate glasses show improved ionic conductivity when some of the oxygen in the phosphate tetrahedron is replaced by nitrogen. As such...

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...

Oxalyl chloride (mpt. 260 K), forms an ordered phase at low temperature, but a disordered phase between 250 K and the melting point. In previous beamtime we aimed to carry out...

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...

Ferroelectric BaTiO3 (BT) constitutes a base system for many practical applications ranging from classical capacitors to tunable dielectrics. A dielectric response in BT is...

PIPD is a polymer with unusual tensile and compressive strength. Inter and intramolecular H-bonding interactions are thought to be responsible for these properties. PIPD is also...

The primary aim of this proposal to investigate a series of newly discovered Bi- containing ferroelectric systems based on Bi(Me’Me’’)O3-PbTiO3 perovskite through studying their...

The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong...

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...

The ionic conductivity of sodium chalcogenide or chalcohalide glasses is 2 to 3 orders of magnitude higher than that of oxide glasses and comparable with lithium ionic...

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...

Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial...

We have prepared some new mixed-metal oxides using a chemical synthesis approach that provides access to materials not seen using other techniques. The materials are potentially...

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....

The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this...

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...

Metal-organic framework materials are a family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these materials show...

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 ¿...
