The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the...

We ask for 4 days on NIMROD to study the atomic- and intermediate-range order of ammonia-borane (AB) intercalated into mesoporous MCM-41. Ammonia borane is one of the leading...

It is proposed that the lattice parameter change at high temperature is measured for a mix of 316L and SA508 grade 3 steel powders, by means of neutron diffraction in High...

Nimrod is a unique instrument that bridges atomic resolution solution scattering with small angle scattering. The opportunity therefore exists to probe both the microscopic...

Tetragonal R(Fe,M)12 compounds (R=rare earth, M transition metal or Si), with the ThMn12 structure, are good candidates as permanent magnet materials with reduced R content....

Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic...

Group 1 amides of general formula MNH2 are some of the most promising materials for hydrogen storage applications due to their relatively low temperatures of hydrogen evolution...

The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an...

The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are...

Catastrophic failures of lithium batteries is a major safety concern, however our understanding and control over the mechanisms of these failures is still lacking. Lithium is...

Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common...

Vanadium based compounds have attracted considerable interest as positive electrode materials for Li ion batteries. This is due to vanadium’s ability to display a range of...

Thermogravimetric analysis on alkaline earth hydrides in St Andrews has revealed a remarkably fast exchange of deuterium and hydrogen by alkaline earth hydrides at relatively...

The recent discovery of skyrmions and skyrmion lattices in materials with no inversion symmetry and their corresponding potential applications of Skyrmions in magnetic...

Supercritical CO2 is an interesting medium for supercritical fluid extraction of aromatic molecules, due to the low temperatures and pressures needed to the process. Methanol is...

In our recent beamtime (RB 1820043 TOSCA and RB 1820044 MAPS), we prepared a series of ZSM5 samples that had undergone the ethanol-to-gasoline (ETG) reaction for different times...

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose...

Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid...

One of the main challenges in spintronics research is to provide a link between magnetic elements and conventional electronic circuits. A novel approach to this old problem is...

Hybrid perovskites, composed of an organic cation, inside a post transition metal halide framework, have emerged as simple, low cost solar cell materials, with power conversion...
