Inelastic neutron scattering from H_2 in binary clathrate hydrates
The proposing team is interested in exploring the rotational and translational dynamics of molecular hydrogen trapped in water-based cages (clathrate hydrates). These systems... -
Structure of a clathrate hydrate inhibitor in water
Gas hydrates (crystalline inclusion compounds of water and small hydrocarbons) present a very real challenge to the petrochemical industry. In uninhibited systems gas hydrates... -
Phase behaviour of methane clathrate under conditions relevant to Titan's int...
Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is... -
Helium quantum rattling in clathrate hydrate cages studied through neutron Co...
The proposing team is interested in exploring the low-temperature quantum "rattling" dynamics of helium atom(s) trapped in water-based cages (namely the so-called "clathrate... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
Crystallization of clathrate hydrates from amorphous THF-water solutions
Understanding clathrate hydrate formation and stability is an urgent issue due to their environmental importance. However, a fundamental understanding of the molecular processes... -
Structural investigations of type-I clathrate compounds
This proposal concerns structural investigations on thermoelectric type-I clathrate compounds Ba8Ge43 and Cs8Sn44. Both compounds possess vacancies in their crystal structure... -
Phase behaviour of methane clathrate under conditions relevant to Titan's int...
Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is... -
Diffusion of molecular hydrogen into pre-formed THF clathrate hydrate
The proposing team has a well established experience in the use of neutron scattering on samples containing molecular hydrogen, and has recently studied some aspects of the...
