This proposal focuses on a new approach to the formation of rod-like micelles in supercritical CO2 (scCO2). Recent successful high-pressure SANS (HP-SANS) results have shown for...

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...

This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of...

The Li?N?H hydrogen storage system is one of the most promising candidates for hydrogen storage in vehicular applications and the addition of halide ions significantly increases...

We request 3 days beam time on POLARIS for the in-situ study of the crystalline phase composition of iron, manganese and ruthenium catalysts for ammonia decomposition. These...

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...

The magnetism of spin-crossover (SCO) materials containing Fe(II) can be switched by changing conditions. The low-spin state existing at low temperature or high pressure can be...

Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earth’s inner core just before...

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

New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have...

This is a continuation proposal to the previous study (RB. 1720418) of NaCoO2. Even if the data analysis is still under process, the result could indicate that the transition...

This proposal seeks 2 days on POLARIS in order to fully complete the commissioning of a large volume in-situ reaction cell for studying hydrothermal chemical syntheses in...

We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have...

Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating...

This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently...

The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we...

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...

The proposal aims to explore water-in-CO2 (w/c) microemulsions with very promising hybridCO2-philic surfactants. The surfactants have been systematically synthesised...
