The aim of the present proposal is to complete a systematic study on the effects of isotopic and chemical substitution on the thermal expansion and vibrational properties of...

We wish to exploit the contrast afforded by neutrons to study the ordering of In and Sn cations in indium tin chalcogenides. Cation ordering has been inferred from spectroscopic...

Polymeric films thinner than a 100 nm exhibits a variation of the glass transition temperature of a few tens of degrees and can brake up into discrete islands when heated near...

We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found...

The effect of alloying additions (Ni, Fe, Cr, Ta, Mo, V, Ti, Si) on the misfit of developmental Co-Al-W alloys will be examined using Polaris. The Co3(Al,W) precipitate phase...

Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a...

Pyrolysis is considered as a sustainable way to generate energy from bio-oil, however, biochar – a solid residue by-product– is inevitably produced in the production line. We...

Bismuth niobate (BiNbO4) is widely used in multilayer RF and microwave components such as capacitors and chip layer capacitors. This compound exhibits two main structural forms...

The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously...

Atmospheric levels of CO2 are increasing at uncontrolled levels and as such methods of CO2 utilisation are being researched. A key reaction for this purpose is the coupling of...

Building on a successful programme investigating aspects of iron based Fischer-Tropsch synthesis (FTS) catalysts, it is opportune to extend that work to include Co FTS...

The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have...

Thermoelectric devices are capable of converting thermal energy directly into electrical energy. The efficiency of a device is related to the characteristics of the materials of...

Bi0.7La0.3FeO3 has received extensive attention in the past years, since this compound exhibits simultaneously ferroelectricity and ferromagnetism at room temperature. Despite...

We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste...

The objective of this proposal is to spectroscopically identify the nature of surface species formed during the addition of tert butyl hydroperoxide onto the surface of the...

As part of an on-going programme of work to better understand critical factors in the methanol-to-hydrocarbon process over ZSM-5 zeolite catalysts, it is becoming increasingly...

Ammonia borane, NH3BH3, has been extensively studied as a potential hydrogen storage material because of its high hydrogen content (19.6wt%) and relatively low decomposition...

Since magnetism in Fe-based superconductors (SCs) show many similarities to that in Cr, investigation of the overall spin dynamics of antiferromagnetic (AF) metal will give...

We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....
