In situ composite materials based upon refractory metal - silicide eutectics are being considered for high temperature structural applications. These materials derive their high...

With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron ? cm size range, where relative velocities...

Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is...

Our group has been working partially oxidized cellulose nanofibrils which form gels in aqueous formulations. Recently we have observed that these fibrils also gel when dialysed...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

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...

Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important...

Antimicrobial peptides (AMPs), also called host defense peptides, are part of the innate immune system of essentially all species, from bacteria themselves to mammals to protect...

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...

In the proposed experiment ammonia borane (NH_3BH_3) will be investigated through incoherent inelastic neutron scattering on TOSCA at low temperature. Since it is well known...

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...

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...

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...

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...

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

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...

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...

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