Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

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...

We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The...

The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production...

Studies of internal dynamics in the pico seconds timescale, of cyt c trapped in MCM-41, would allow the forms, geometry, amplitudes and time-dependence of the motions involved...

We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

The proposers have obtained a dispersive Raman spectrometer that is fibre optically coupled to a custom centrestick that will allow simultaneous Raman and neutron measurements....

These experiments are part of a much broader programme at the University of Reading. focused on the use of water-soluble half-acetylated chitosan as a mucoadhesive polymer,...

We propose to use the OSIRIS spectrometer to measure the inelastic magnetic scattering on the newly discovered heavy Fermion compound Ce3Co4Sn13. This compound has one of the...

The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity...

Previous experiments at ENGIN-X (Wenk et al. 2007) established that quartz rocks undergo mechanical twinning if stressed above 100 MPa. The amount of twinning is highly...

In this proposal we wish to continue our current work on mesostructured inorganic films in largely ethanolic solutions, containing limited amounts of water. Transition metal...

Nitridosilicates and oxonitridosilicates (sions) gain more and more importance as host lattices for rare-earth doped phosphors in light emitting diodes. By means of...

The aims of the experiment are (1) to obtain structural data for the model hydrogen storage intermetallic LaNi5 under a deuterium pressure of 3000 bar at cryogenic temperatures,...

The structures of emulsions formed from mixed oil-soluble and water-soluble amphiphiles (respectively derivatives of polyisobutylene, PIBSA, and polyacrylamide, PAM) will be...

It has very recently been shown that Mott-insulators located at the crossover regime closer to the itinerant side, such as RNiO3, undergo a pressure-induced transition into a...

Residual stresses introduced into large aerospace aluminium components after the queching procedure carried out to form the desired microstructure can result in large, costly...

This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to examine the differences between a sample of Sr2CoO2Cu1.85S2...

NMR has become an extremely sophisticated experimental technique because of the use of pulse sequences which allow the control and manipulation of a nuclear spin system or...

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....
