Interactions between a polymer brush grown from a macro-initiator-modified sa...
We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator... -
Nanoemulsions for dermatological drug delivery
Nanoemulsions have considerable potential for dermatological drug delivery. Small angle neutron scattering in combination with contrast variation will be used to characterize... -
Evolving structures of oxysulfide battery materials
This proposal aims to investigate the evolution of the structures of layered oxysulfide materials which show promise as lithium ion battery electrodes. The lithiation of... -
Effect of grain size on stress partitioning within plastically deforming two ...
We request 4 days of beamtime on ENGIN-X to measure the influence of relative grain size on stress partitioning between the constituent phases in two phase polycrystalline... -
Dynamics of Polymer Rings
This proposal is part of our research efforts aimed at the understanding of the static and dynamic properties of cyclic polymers and their comparison to linear chains. Previous... -
High Pressure Thermoelastic Properties of Thermoelectric PbSe
We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Light induced structural changes in hybrid lead-halide perovskites CH3NH3Pb(I...
A controlled investigation of light-induced changes in hybrid perovskites is required to achieve stable operation of tandem solar cells and colour-tuneable light-emitting... -
Diffraction Resistance Measurements of a Chalcopyrite
During the course of a PhD project funded by CCLRC's CMPC, we have developed a cell that allows electrical transport property measurements to be made simultaneously with the... -
Inelastic neutron scattering study of spin gap formation in two forms of BaRuO3
Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through... -
Investigation of short range magnetic correlations in CeIr3Si2 using SR
CeIr3Si2 reveals highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall crystal electric field (CEF) splitting of the J=5/2... -
Investigating the Dissolution Mechanism of Cellulose in Ionic Liquids
Cellulose is one of the most abundant renewable natural resources on Earth, and it has been estimated that in the order of 400,000 tonnes/year of paper and additional 100,000... -
The competition between two polymers for adsorption onto one surface
The behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We... -
Investigation of the intermolecular dynamics of polycrystalline C60
Recent work by the proposers on modelling the coherent inelastic neutron scattering spectrum for polycrystalline samples of the two phases of this material has shown that all of... -

Neutron powder diffraction studies of layered rock salts LiCo0.1Mn0.1Ni0.8O2 and LiCo0.1Mn0.1Ni0.8O2-d -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy... -
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... -
Muon Spin Resonance investigations on two quantum critical points in CeFeAs1-...
Recently, it has been reported that CeFeAsO belongs to orthorhombic structure where both Fe and Ce moments order antiferromagnetically around 140K and 4K, respectively, whereas... -
SANS Investigation on Packing Structure of Proteasome Activator 28
Proteasome plays an important role in the processing of antigenenic proteins for presentation by the MHC class I pathway. PA28 is an activator of the 20S proteasome, a large... -
Tuning B-B exchange in the R2MnMn(Mn4-xTix)O12 quadruple perovskite manganites
For the RMn3O6 manganites, we have shown that tuning A-B exchange, by choice of A-site cation or by doping magnetic impurities, gives rise to dramatically different magnetic...
