Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for...

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...

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...

The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,...

Neutron scattering is one of the few experimental techniques that can directly determine the state of confined H2 molecules in microporous solids. In this proposal, we seek to...

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...

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...

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...

Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these...

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...

The study of organic based materials is a popular topic and spans both chemistry and physics and presents some significant advantages. Of interest within this proposal is the...

Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering...

We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental...

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...

The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is...

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...

We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of...

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...

Whilst rechargeable batteries continue to take over the consumer electronics market, they are unsuitable to replace specific battery technologies, such as the thermal battery,...

In typical odontological studies water sorption in the restoration material is determined by weighing freshly mixed cement at regular intervals. In the case of resin-modified...
