In a recent SURF experiment on the formation of silica films templated with cat-anionic/polymer complexes we found that the film growth and evolution occurs on a faster time...

Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high...

Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in...

The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen...

We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have...

In the last decades the production and consumption of reactive nitrogen increased exponentially due to the extensive utilisation of nitrogen containing compounds as fertilizers...

The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects cloud droplet size and optical properties, important climatic...

We will investigate the structure of 4-chloroimidazole a material, which undergoes extreme anisotropic thermal expansion,.as a function of pressure at a range of temperatures...

Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical...

In a previous proposal we started to study the micellar structures formed from biodegradable surfactants synthesised using amino acids as the headgroups. The aim of this work is...

Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice...

This proposal will explore the effect of elevated pressure on the behaviour of two important hydrogen peroxide solvates of the explosive CL-20. We will use neutron diffraction...

In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of...

A surfactant-free microemulsion is ternary system consisting of two completely miscible molecular liquids and a third one that is only highly soluble in or miscible with one of...

In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of...

Inexpensive light-metal amides are among the most highly active and effective ammonia decomposition catalysts at modest temperatures and are likely to surpass the performance of...

Bearings are essential components in many types of machinery, working to reduce energy losses. Over the last century improved analytical models were developed for predicting the...

The objectives of this proposal is to seek 2 days on POLARIS in order to test and complete a full commissioning of the latest design of our prototype in-situ reaction cell for...
