This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of...

Water plays a critical role in determining the structure and function of biological system. A hydration level, h~0.2 g water/g protein, is often found to be the minimum...

The myelin sheath is a multilayered membrane wrapped around axons in the vertebrate nervous system; it enables the rapid transmission of nerve impulses. It contains a set of...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

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...

Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well...

Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...

We aim to utilise Low-Energy Neutron Scattering (LENS) at OSIRIS to investigate the effects of gas adsorption on the quantum rotation of the methyl groups present in a Metal...

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...

Understanding clathrate hydrate formation and stability is an urgent issue due to their environmental importance. However, a fundamental understanding of the molecular processes...

Atomistic characterisation of phase transitions in organic materials is important because of the role played by polymorphism in pharmaceuticals and agochemicals. Conventional...

A recent beautifully resolved INS spectrum of solid ammonia shows distinct differences in phonon states compared to initial calculation. This suggests that strong...

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...

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...

Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which...

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...

Ammonium sulfate has a well-known order-disorder phase transition at -50 ºC: initially of interest for the ferroelectric behaviour in the low-temperature phase, this has...

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...

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...

An inelastic X-ray investigation on the collective inelastic dynamics of molten NaCl revealed the remarkable result that the acoustic-like dynamics is similar to the dispersion...
