The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also...

This proposal seeks 2 days on POLARIS in order to study hydrothermal chemical syntheses of yttrium aluminium garnet, Y3Al5O12 (YAG) in supercritical water using the...

This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum magnets. A canonical model is the spin-1/2 triangular antiferromagnet...

Ultrasound is a very attractive and patient-friendly imaging technique, as it is easy to use, fast and non-invasive. Nevertheless, its use is severely limited by the low...

The Earth's climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important effects. Common...

Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

We request 3 days’ beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or...

Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride...

We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and...

We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data...

Glass Ionomer Cements (GICs) have found numerous applications as bone fillers, replacements and adhesives, particularly in dentistry due to their tooth like appearance and...

Using ISIS facilities, our team has discovered three new phases of ice: ices XIII, XIV and XV. These phases form in the presence of small amounts of hydrochloric acid. Yet, the...

Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8. This...

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

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...

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,...

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 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...
