Structural changes in LiMO2 anode materials
It was thought that oxides could not intercalate Li below 1.5V vs Li+/Li. We recently studied layered LiVO2, which intercalates Li at around 0.25V to form Li2VO2, making it an... -
Crystal Structures of Multiferroic MnWO4: HRPD
Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex... -
Study of nano-electrode materials for Li-ion batteries combining small-angle ...
Nano-materials are of interest in the field of energy conversion and storage due to properties not seen for the bulk. However, due to their non-periodic nature, the atomic... -
Reverse Monte Carlo study of Silicon anode materials for Lithium-ion batteries
The performance of current commercial Li-ion batteries with graphite anodes is limited by the relatively small amount of lithium that can reversibly intercalate between the... -
Composition depth profiling of novel spray-coated plastic solar cell materials
We propose to study a range of new lower energy gap organic photovoltaic (OPV) materials deposited by spray coating using neutron reflectivity. The new materials to be studied... -
Direct measurement of hydrogen storage capacities of nanoporous materials via...
Absolute hydrogen capacities of nanoporous storage materials cannot be accessed using conventional gas sorption experiments, but can be estimated by modelling experimental... -
QENS studies of Na-ion 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... -
Structural investigation of perovskite-based ferroelectric materials through ...
The aim of this proposal is a comprehensive structural investigation of a technologically-important perovskite-based ferroelectric material xBiScO3-(1-x)PbTiO3 through studying... -
A Study of the Reduced interfacial Magnetisation in a Heusler/Insualator Tunn...
For many Heusler compounds a spin polarisation close to 100% was predicted by band structure calculations. Thus if those materials are incorporated in magnetic tunnel junctions,... -
Off-specular reflectivity from conjugated polymer heterojunctions
Using conjugated polymers as the active materials in electronic and optoelectronic devices opens up the possibility of fabricating all-polymer devices, such as active matrix... -
Structure and magnetic properties of materials derived from Apuanite and Vers...
We aim to determine fully the variation in charge order of synthetic Versiliaite and Apuanite samples by monitoring structural and magnetic order as a function of temperature,... -
Investigation of the multiferroic materials Ba3Dy2GaNb9O30 and Ba3.5Dy2Ga1.5N...
We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic... -
High-pressure studies of energetic materials
This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and... -
Diffusive behavior in battery materials under electric field
Lithium diffusion in magnetic materials is found to be well detected by muon-spin spectroscopy. However, such a diffusive behavior has been measured without potential gradient,... -
A µSR study of the charge density wave superconductor CuxTiSe2.
Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and... -
Identifying the mechanism behind spin relaxation in organic materials
We wish to measure the low-field ALCs of a series of related functionalised acenes to identify which mechanism (spin orbit or hyperfine) is responsible for spin relaxation in... -
In-situ conductivity study of double perovskites for use as potential anode m...
It is a challenge to develop materials for use in fuel cell applications. Presently we are preparing new perovskite and double perovskite structured compounds being potential... -
