Very rapid quenching of liquids to form a glass, from which crystalline phases are subsequently obtained by devitrification, is a powerful technique for obtaining novel...

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...

Studies on the structure and dynamics of nano-confined water are relevant and up-to-date not only for the understanding of the physics of water bu also for their implications in...

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...

It is a well established fact that several molecular liquids experiences a series of thermal anomalies as measured by microscopic and macroscopic techniques. A remarkable case...

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...

An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5...

We have a long-standing interest in the temperature- and magnetic field-evolution of magnetic and crystal structure in CoMnSi. This is driven by an interest in the...

Bismuth ferrite is the most widely studied multiferroic material primarily due to the observation of both room temperature magnetic and electric ordering. Despite extensive...

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...

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...

Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:...

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...

This proposal aims to investigate the dynamics of ortho-/meta-/para- xylene, mesitylene and 1,3,5- Trihydroxybenzene. Improved understanding of their dynamics is relevant to...

We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data...

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

This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the...
