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...

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...

Quantum critical points (QCPs) have attracted continuous scientific interest due to the emergent phenomena observed in their vicinity, including unconventional superconductivity...

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...

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...

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...

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 recent high pressure experiments (S. Klotz et al., Nature Materials, DOI 10.1038/ NMAT2422, 23.4.2009) we discovered a salt hydrate based on a high-pressure ice form, i.e....

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...

It is proposed to use small-angle neutron scattering (SANS) to investigate in detail the binary phase diagram between 1-ethyl-3-methylimidazolium...

Gram negative bacteria cause a wide range of diseases including meningitis, bubonic plague, gonorrhoea, diarrhoea, Legionnaires' disease and cholera. Their outer membrane...

Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the...

We have recently developed a new system of refractive-index matched nanoparticles. This system has advantages over a extensively used one of polymer latexes; ours 1) can be...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...

Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...

The objective of the proposed experiment is to develop an understanding of the Li/Ni/Mn ordering in a commercially relevant lithium ion battery positive electrode,...

We propose to investigate the excitation spectrum of azurite in both zero field and applied fields up to 7T. Using inelastic neutrons on OSIRIS we hope to clearly resolve the...

This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of...

Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from...

Here the use of the IGAN system for in-situ TGA and neutron diffraction is proposed in order to study the de-hydration of four proton conducting materials. The selected...
