During the operation of nuclear plants, several fission products are released. Among them, radioiodine is considered one of the most important due to its tendency to form...

We have obtained the monolayer structure diffraction patterns from several iodoalkanes adsorbed on graphite, of interest in the study of non-covalent bonding. However, it is...

We have carried out detailed investigations on the ferromagnetic (FM) Kondo lattice CePdSb, in polycrystal as well as single crystal form (TC=17.5K) using magnetization, neutron...

Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic...

Ethanol is a compound that is ubiquitous: it is the key ingredient in alcoholic drinks, it is used in low temperature fuel cells and has even been observed in interstellar...

Vapour grown carbon fibres constitutes a promising material for hydrogen storage for transport applications. The reasons are its low cost, simple manufacturing process and...

Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have...

We have studied the absorption of nitrogen gas in MCM41 on NIMROD at a pressure of 1 bar and at temperatures to 87K (A K Soper and D T Bowron, Chem. Phys. Lett., DOI:...

Two days of beamtime on HRPD will be used to examine a family of double perovskites Sr2YbMO6 that are isostructural at room temperature. When M = Mo5+ the monoclinic perovskite...

High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In...

Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the...

In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual...

Layered perovskites are well known functional materials but, in the context of fluoride chemistry, have so far been restricted to purely inorganic examples: K2NiF4 is the...

The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based...

This proposal forms a very specific part of our project to investigate complex magnetic structures in rare earth intermetallics. In extensive bulk measurements on high purity...

We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

The physisorptive capability of graphite-based nanomaterials for hydrogen is strongly dependent on their surface areas and nanomorphologies. We have made electrospun graphite...

Antiferromagnetic interactions on geometrically frustrated lattices such as the fcc lattice can result in novel magnetic states and structures. Ba2CoMoO6 is an fcc...

Magnetically frustrated materials are unable to adopt the regular long-range ordered states observed in conventional insulating transition metal oxides. Instead they tend to...
