Spin Waves in the Parent Compound of the Superconductor FeSexTe1-x (x=0)
The iron containing superconducting system FeSexTe1-x has a similar phase diagram to the cuprate superconductors, in that a non-superconducting antiferromagnetic parent compound... -
Thermal expansion of hexa-halogenated benzenes: C6Cl6, C6Br6, C6I6.
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... -
Structure and cation ordering in A2Sn3Q7-type phases (A=In, Cr; Q= S, Se)
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... -
The magnetic excitation spectrum in Fe1.07Te
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... -
Misfit and Misfit Release in Co-Co3(Al,W) Superalloys
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... -
A high-temperature neutron powder determination of the phase transition and c...
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... -

Phase behaviour and dielectric phenomena in bismuth niobate energy storage ma...
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... -
Further investigation of the methanol to gasoline reaction over ZSM-5 using INS
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... -
First experiment with a pulsed field magnet at ISIS or how to break the 15T b...
We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the... -
Analysing intermediates of a CO2 insertion reaction using simultaneous operan...
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... -
Possible amorphous:amorphous phase separation in bioactive glass containing s...
There is an interest in understanding the nature of fluoro-alumino-silicate glasses based upon the apatite stoichiometric composition and of potential within ionomer cements for... -
The chemisorption of hydrogen over a Raney cobalt catalyst: An INS investigation
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... -
High energy spin excitations in SrCo2As2
the correlation degree in 122 iron pnictides mainly depends on the electronoccupancy of each orbital and that by doping electrons the correlation decreases monotonically. This... -
Investigation of the nature of organic surface species formed on Au-based sup...
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... -
Neutron Scattering and Structural Measurements of CO2 and CD4 Adsorption in M...
Shale is an increasingly viable source of economic quantities of natural gas worldwide. Most of the gas is contained within the fine pores, thus characterizing accessibility and... -
Studying the strength of acid sites in an industrial ZSM-5 catalyst: MAPS
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... -
Neutron diffraction study of local and mesoscopic disorder induced by La and ...
The accurate determination of the defect structure of rare earth (RE) doped ceria solid electrolytes is fundamental for the comprehension of oxygen diffusion and charge... -
MAPS Investigation of the decompositon of LiNH2BH3
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... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
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....
