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...

Nd2Zr2O7 is a new candidate prominent to quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field...

Fullerenes often produce very dramatic improvements to polymer properties, but their limited miscibility with polymers is often a severe restriction to the general utility. We...

Recent published studies have identified a stable solid form of carbonic acid at high pressure. This proposal is for beamtime to collect the data to solve its crystal structure.

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 use of ionic liquids for electrochemical devices such as supercapacitors, dye sensitised solar cells and lithium ion batteries has led to significant advances in technology....

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...

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...

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,...

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...

Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the...

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...

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...
