We propose to use OSIRIS to investigate the changes in magnetic ordering which occur when a series of layered oxysulfides with mixed-valent Mn ions in their oxide layers are...

All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make...

Poly(ethylene)s carrying multiple end-functional groups on a single chain end have been prepared from polybutadiene, saturated with either hydrogen or deuterium. These materials...

This experiment will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to correlate magnetic and...

In this proposal we investigate the adsorption of a key additive and functional group used in lubrication and wear applications using neutron reflection on a metal oxide...

This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to examine the differences between a sample of Sr2CoO2Cu1.85S2...

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...

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...

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...

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

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...

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...

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 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...

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...

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 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...

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...

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...
