QENS on Halide Stabilized LiBH4
LiBH4, is an ionic solid, consisting of Li+ and BH4- ions. It undergoes a structural phase transition at 383K. Within the HT phase, the BH4-units undergo rapid re-orientations,... -
High-pressure, high-temperature studies of energetic materials - RDX and HMX
One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is... -
Water diffusion mechanism in hydrated amorphous calcium carbonate
Calcium carbonates are highly important in geochemistry and especially in biomineralization. In nature, organisms can form each of the anhydrous polymorphs selectively for... -
Chemical control of structures and magnetic ordering of cobalt oxide chalcoge...
The response of the magnetic ordering of layered cobalt oxide chalcogenides to changes in electron count will be investigated in detail following a preliminary experiment at... -
Dynamics of Water on Surface of Reverse Osmotic Membranes
We are proposing 10 days of beamtime on IRIS to investigate the diffusion process of H2O molecules adsorbed on polyamide, surface material of reverse osmotic membranes currently... -
Probing nanophase segregation in aqueous solutions
In recent experiments we accidentally observed the onset of nanophase segregation in concentrated LiCl-water solutions by increasing dilution, in the deeply undercooled regime.... -
Spin gap opening associated with an extraordinary magnetovolume effect in som...
We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers... -

Structural phase diagram of hydrated silks
The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich... -
Thermal expansion and ordering in D2O ice III / IX
The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are... -
Vibrational Dynamics of Alkali Silicate Glasses - An Isotopic Mass Contrast S...
The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman... -
Short range static and thermal disorder in glasses and crystals
We seek to use the temperature-dependence of the neutron correlation function to investigate the extent of static disorder in glasses and crystals, and also to investigate the... -
Study of structural and phase transitions of carbon dioxide confined in the n...
The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental... -
Is Zeolite Deactivation Through Pore Blocking?
Zeolites are porous framework materials that have active catalytic sites inside narrow channels. Unwanted reactions create coke in the pores which may block access to the active... -
Phase Transitions and Orbital Ordering in SrRu1-xCuxO3.
This proposal seeks to establish the importance of orbital ordering on the stability of the tetragonal phase in Cu doped SrRiuO3. Orbital ordering is believed to be a... -
QENS Investigation of Solid Ammonia
A recent beautifully resolved INS spectrum of solid ammonia shows distinct differences in phonon states compared to initial calculation. This suggests that strong... -
Crystallization of clathrate hydrates from amorphous THF-water solutions
Understanding clathrate hydrate formation and stability is an urgent issue due to their environmental importance. However, a fundamental understanding of the molecular processes... -
Melting point dynamics of Confined fluids
This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is... -
THE IMPACT OF HYDROGEN-BONDING CONTACTS ON THE PROPERTIES OF ALKYLAMMONIUM PR...
Ionic liquids are of interest to chemistry and material sciences because of their designer properties.The protic ionic liquids (PILs) are excellent proton carriers in fuel cell... -
Structural and Magnetic Properties of New Pb2FeTeOx Phases
Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...
