CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle; it also occurs as a major phase at lower pressures and temperatures in subduction zones, where,...

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...

Microwave dielectric ceramics are used in communications devices. Such materials need high relative permittivity, high dielectric quality factor and be temperature stable....

We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and...

Freezing of fluids confined at the nanoscale is of great importance for the understanding of their behaviour due to the confinement effects arising from the finite pore size and...

The physical properties of the perovskite family remain an enduring topic in solid state research. In this proposal we aim to study the solid state structural phase transitions...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...

Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...

Supported ionic liquid membranes offer potentially lower-energy alternatives to cryogenic distillation for the separation and isolation of light gas olefins (ethene and propene)...

Sr2IrO4 is an important material in the field of condensed matter physics, being a proposed J_eff=1/2 Mott insulator. Recent publications have shown that the reported low- and...

Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal...

We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium...

Metal organic frameworks (MOFs) are a particularly interesting class of three dimensional crystalline networks formed by the self-assembly of metal ions with organic ligands....

The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and...

We propose to perform neutron diffraction experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic...

We request 1 day of beam-time on POLARIS to collect Neutron Diffraction (ND) data on the Sillenite Bi12SiO20 (gamma-Bi2O3) that we have recently discovered to exhibit a...

It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =...

The aims of the experiment are (1) to obtain structural data for the model hydrogen storage intermetallic LaNi5 under a deuterium pressure of 3000 bar at cryogenic temperatures,...

Porous materials impregnated with metal nanoparticles are extremely useful in catalysis, an industry that had a global turnover in 2010 of over three trillion dollars....

There are great energy costs associated with the separation of the light olefins (ethylene and propylene) from mixed hydrocarbon gas feeds. These olefins (obtained from natural...
