The mechanism of Oxygen Absorption/Desorption in YBaCo4O7+d (Y114) studied by...
An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5... -
Compositional analysis and working technique determination of five Japanese T...
The Pitt Rivers is Oxford University¿s museum of anthropology and world archaeology. The Japanese material includes a large number of items of metalwork. Amongst these, the... -
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... -
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... -
Unique disorder in the ammonia hydrates at high pressure
The ammonia hydrates are important systems for the understanding of the hydrogen bond and for models of the outer solar system. This proposal is for beamtime to explore the... -
Phonon confinement effects in Si-nanowires
Nanowires can be used for devices based on thermoelectrics and to convert the heat into electrical current. The material design challenge here is to create the materials where... -

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... -
Dynamics of Disorder in Relaxor-like Ferroelectric AB(HCO2)3 Frameworks
Relaxor ferroelectics are of significant interest for use as piezoelectric actuators in sensing applications and for high precision mechanical stages. Relaxors are traditionally... -
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... -
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... -
MuSR detection of optically-injected spin-polarized electrons in Silicon
Silicon is currently the base of all modern electronics and advanced computing. One route to future advanced computing called spintronics exploits the energy saving and quantum... -

We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data... -
The possibility of strongly ferromagnetic austenite in a stainless steel
It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =... -
The pressure response of the new superconductor LiFeAs
We will probe the response of the 18K superconductor LiFeAa to pressures of up to 2 GPa in order to investigate the evolution of the crystal structure. In particular we wish to... -
