In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD...

There is currently considerable research interest in the synthesis and characterisation of materials with high oxide-ion conductivities, owing to their potential exploitation as...

This proposal is part of a new research programme at Reading which is focused on a new types of macromolecular structures namely conetworks and pseudo-conetworks. These are...

Zeolites are perhaps the most successful microporous materials used for catalysis and separation processes in refineries and chemical industries[1-3]. This is due to the...

We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with...

Magnetoresistance (MR) is defined as the relative change in the compound electrical resistivity upon application of an external magnetic field. It is the fundamental property on...

We wish to investigate a new series of materials in which manganese in benavidesite, MnPb4Sb6S14, is progressively replaced by iron, leading to jamesonite at complete...

The structure of GeSe4 glass will be measured using the method of isotope substitution in neutron diffraction with both Ge and Se isotopes. This material is representative of a...

The key objective is to measure three samples of composition Fe(1.05)Te, Fe(1.12)Te, and Fe(1.14)Te as a function of temperature (base to 80 K) through their magnetic ordering...

We wish to perform a detailed and comprehensive study of the structure of lead germanate glasses, over a wide range in composition. Most structural studies of germanate glasses...

We have recently completed x-ray reflectivity, neutron reflectivity [RB810041], and sum frequency spectroscopy experiments using non-ionic surfactants adsorbed at the...

We propose to measure the structure of glassy Ge2Se3 and GeSe9 which lie at either end of the glass forming region in the Ge-Se system. The motivation is provided by the need to...

Gas clathrate hydrates are crystalline inclusion compounds formed when water and gas come into contact at high pressures and low temperatures. To date there are only three...

Proteasome plays an important role in the processing of antigenenic proteins for presentation by the MHC class I pathway. PA28 is an activator of the 20S proteasome, a large...

Due to a high-oxide ion conductivity, strontium and magnesium co-substituted lanthanum gallate (LSGM) is considered as a potential electrolyte material for solid oxide fuel...

At ambient pressure TiCl4 forms a molecular solid consisting of isolated TiCl4 molecules (phase-I). At 0.5 GPa this structure undergoes a transition to phase-II, which is...

A long term goal for biophysical studies has been to fabricate bio-membranes on solid supports. A highly hydrated ¿cushion¿ between the membrane and the underlying support can...

Adsorption of colloidal particles to an interface is of fundamental interest in understanding wetting, capillarity and colloidal forces as well as being of practical importance...

The L3 (sponge) surfactant phase is a promising template for inorganic materials since it is composed of large, uniform water-filled pores separated by a surfactant bilayer. If...

Conjugated organic semiconductors form an exciting class of materials that can be used in a variety of cutting edge technologies including organic light-emitting diodes (OLEDs),...
