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...

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...

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...

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 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...

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...

In this experiment we will determine the detailed structure of the 6 K superconductor LiFeP and phases close in composition which are iron rich: Li1-xFe1+xP. This will enable...

The recent discovery of superconductivity in a series of iron pnictide materials has provided impetus to the field of new materials discovery. Like in the cuprate...

This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are...

We have recently shown that the addition of single walled carbon nanotubes produces a minimum in the diffusion coefficient with increasing nanoparticle concentration. Initially,...

We have recently prepared and studied the surface properties of some well-defined multi-end functional polyethylenes. Whilst most of our surface studies indicate that these...

Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to...

Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is...

We propose to use POLARIS to perform two related experiments. Firstly we will investigate the structures and compositions of derivatives of some layered Mn/Cu oxysulfides which...

We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions...

In this novel proposal we will investigate adsorption onto the non-equilibrium face of calcite the first time this has been attempted. This will compliment and extend our...

We propose to use POLARIS to obtain detailed structural information on a series of new lithium-containing layered oxychalcogenides and to investigate the ordering of lithium...

We have recently shown that the addition of single walled carbon nanotubes produces a minimum in the diffusion coefficient with increasing nanoparticle concentration. Initially,...

The recent discovery of superconductivity in a series of iron pnictide materials has provided impetus to the field of new materials discovery. Like in the cuprate...

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...
