In this proposal we investigate the adsorption of the key dispersant additive, sodium polyacrylate, used in colloidal systems using neutron reflection on aluminium oxide, with...

The aim of this proposal is to determine the thickness of a water layer surrounding colloidal particles dispersed in oil with changes in ionic strength. Recent work by our group...

Here we aim to structurally characterise the formation of adsorbed monolayers of heparin on calcite to address how these species influence biomineralisation and the inhibition...

The interface of CaCO3 (calcite) and water or oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery and scale deposition in...

In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself...

Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K...

This is part of a larger experiment which will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to...

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...

We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated...

The lubrication of surfaces by oils is a key aspect of many academic and industrial problems with significant financial implications. In this experiment we would like to extend...

We propose to use HRPD to determine the detailed structures of a series of cobalt oxysulfides containing Co in square planar coordination. Two compositions Sr2CoO2Cu2-deltaS2...

This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to correlate the magnetic structure and the crystal structure of...

The interface of CaCO3 (calcite) and oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery. Neutron reflection has proved to be...

This proposal presents to directly measure ¿bridging¿ of anionic surfactants on an anionic surface through multivalent ions from water under well-controlled conditions (pHs and...

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...

We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to...

Mica is an exceptionally important mineral in surface science, which until now has been inaccessible by neutron reflection. Here we propose a novel attachment method unlocking...

This proposal aims to exploit the high resolution of HRPD and OSIRIS to probe the structures of the solid solution Ba2CoO2Cu2(Te1-xSex)2. The compound Ba2CoO2Cu2Te2 shows...
