Role of interstitial oxygen ordering on the spin excitation of Pr2-xSrxNiO4+d
Dynamics of charge and spin stripe in 214-type nickelets (La2-xSrxNiO4+d) have been investigated intensively in last two decades as similar electronic ordering was found in... -
Structural phase transition in SnSe with ultra low thermal conductivity
SnSe has recently been reported to have very good thermoelectric performance. This is linked to an ultralow thermal conductivity and occurs in the B-phase (ZT > 2 above 800... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
Ligand-field characterization and U-Pt bonding in uranium-based heterometalli...
We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and... -
Ba3MoNbO8.5 novel oxide ion conductor: Direct observation of oxide ion dynamics
Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
Intercalation of Ciprofloxacin into Lithium - Fluorohectorite at acid and bas...
Using quasielastic neutron scattering (QENS) we will investigate the intercalation of Ciprofloxacin (CIPRO) into the synthetic clay Lithium Fluorohectorite (LiFh) to... -
Copy of: Magnetic excitations in the one dimensional (1D) spin-chain systems:...
The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration... -
Mechanism of hydride-ion mobility in a novel oxide-hydride
This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently... -
Pressure-dependence of the anisotropic exchange interactions in two closely r...
There are no magneto-structural correlations for clusters containing transition metal ions with non-zero orbital angular momentum in the ground state. Octahedrally coordinated... -
Understanding the "post-perovskite" structure (I): the Behaviour of CaPtO3 at...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
High pressure polymorphism in ammonium bicarbonate, (ND4)DCO3
In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent... -
Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and... -
Dynamics and Phase Transitions in Catanionic Vesicles
The catanionic vesicles are unilamellar or multilamellar spheroid structure composed of cationic and anionic surfactant molecules assembled into bilayers. Vesicles forms by... -
Structure of a 2D antiferromagnet under pressure
Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic... -
Dynamics of an antimicrobial oligopeptide
Abstract. In experiments at LLB and ILL we have measured low-resolution INS spectra and elastic scans for H2O- and D2O-hydrated samples of a 15-residue oligopeptide between 30... -

This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
Energy dependent, sample transmission correction for time-of-flight diffracti...
Diffraction from hydrogenous materials is complicated by the large incoherent scattering contribution from hydrogen. For many materials the solution is to deuterate before... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism...
