Clathrate hydrates in nature.
Scientific knowledge of natural clathrate hydrates has grown enormously over the past decade, with spectacular new findings of large exposures of complex hydrates on the sea floor, the development of new tools for examining the solid phase in situ, significant progress in modeling natural hydrate systems, and the discovery of exotic hydrates associated with sea floor venting of liquid CO2. Majo...
متن کاملPolymorphism in Br2 clathrate hydrates.
The structure and composition of bromine clathrate hydrate has been controversial for more than 170 years due to the large variation of its observed stoichiometries. Several different crystal structures were proposed before 1997 when Udachin et al. (Udachin, K. A.; Enright, G. D.; Ratcliffe, C. I.; Ripmeester, J. A. J. Am. Chem. Soc. 1997, 119, 11481) concluded that Br2 forms only the tetragona...
متن کاملClathrate Hydrates: Some New Structural Information
INTRODUCTION The accurate prediction of conditions for hydrate formation depends strongly on the availability of good structural information’. For clathrate hydrates, a complete description of structure involves not only the unit cell parameters and average atomic positions, but also the cage occupancies. In order to provide this kind of information, it is necessary to use techniques such as di...
متن کاملRaman spectroscopic studies of hydrogen clathrate hydrates.
Raman spectroscopic measurements of simple hydrogen and tetrahydrofuran+hydrogen sII clathrate hydrates have been performed. Both the roton and vibron bands illuminate interesting quantum dynamics of enclathrated H(2) molecules. The complex vibron region of the Raman spectrum has been interpreted by observing the change in population of these bands with temperature, measuring the absolute H(2) ...
متن کاملObservation of Sintering of Clathrate Hydrates
Clathrate hydrates have recently received attention as novel storage and transportation materials for natural gases or hydrogen. These hydrates are treated as powders or particles, and moderate storage temperatures (around 253 K) are set for economic reasons. Thus, it is necessary to consider the sintering of hydrate particles for their easy handling because the hydrates have a framework simila...
