Inelastic neutron scattering from H_2 in binary clathrate hydrates
The proposing team is interested in exploring the rotational and translational dynamics of molecular hydrogen trapped in water-based cages (clathrate hydrates). These systems... -
In-situ study of hydrogen absorption and desorption in metal-hydride hydrogen...
In order to develop our understanding of hydrogen coordination as a function of pressure within two titanium-chromium-vanadium-molybdenum alloys, Ti10Cr10V75Mo5 and... -
Quasi-elastic neutron studies of superstructure formation in battery materials
LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related... -
Lateral Phase Behavior in bulk heterojunction films containing low-molecular ...
Grazing incidence small angle neutron scattering (GISANS) will be used to investigate the lateral phase behavior in thin films of blends of electron-donor... -
Probing lithium diffusion in olivine materials LiMPO4 using muSR
We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further... -
Structural Characterisation of Silicon Doped Perovskite Manganates and Ferrat...
Our research group have been investigating the structure-property relationship in solid oxide fuel cell materials, with the aim of developing new materials with improved... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Water librations in proton conducting hydrated alkali thio-hydroxogermanates
We propose to perform a systematic study of the intermolecular librational mode of molecular water in the proton conducting hydrated alkali thio-hydroxogermanates... -
Revising the onset of anharmonicity in proteins
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... -
In situ diffraction studies of the archetypal network glass, SiO2 at high pre...
Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of... -
Magnetism in a charge doped cuprate chain
We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing... -
Magnetic Properties of Rare-Earth Carbonates
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... -
Muon Spin Relaxation studies of Ni2TCNQ, Ni(TCNQ)2 and related materials
Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it... -
Temperature induced structural phase transitions in BaPrO3 and acceptor doped...
The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the... -
In-situ study of oxygen storage materials in the Zr-Ce-O system
Zirconia-ceria ceramics are promising materials within automotive exhaust catalysts, exploiting the Ce3+<->Ce4+ redox reactions to store oxygen. For a Zr:Ce ratio of 1:1... -
The Interaction of Ammonia with Binary and Ternary Deuterides;
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... -
