clathrate (kla·thrātˑ),

n a lattice at the molecular level. The phenomenon of having the molecules interwoven within the lattice of another component may explain the method of passing on the active aspects of the source material during potentization of a homeopathic remedy.

For thousands of years--and, in some cases, about 1,000,000 years--huge caches of methane have lain frozen and isolated from the atmosphere, both in the northern latitude permafrost and in the frozen seafloor methane clathrate deposits, in which gas is trapped in a crystal lattice cage of frozen water.
Thus a longer process of synthesis of natural gas hydrates leads to the consistent increase of the ethane concentration, n-butane, propane and i-butane in the clathrate phase.
Ripmeester and Walker, along with student Huang Zeng, MCIC, and post-doctoral worker Lee Wilson, MCIC, were able to conclusively demonstrate that AFPs strongly inhibit the formation of clathrates of THF.
If this is so, methane might be released from its clathrate cages during the eruptions of proposed 'cryovolcanoes' of water-ammonia slurry, or more simply could slowly seep out through fractures in the crust.
If a significant amount of clathrates are disturbed and destabilised it could further increase global warming; he said.
Clathrates have also captured the attention of climate scientists because they may contain ancient samples of oxygen and other gases, says glaciologist Todd A.
The objective of this project is to investigate how silicon clathrates can be used to improve the performance of lithium batteries," said Chan, who will serve as project manager for the four-year effort.
Without the support of the trapped molecules, the lattice structure of hydrate clathrates would collapse into conventional ice crystal structure or liquid water.
Susan Kieffer, a planetary scientist from the University of Illinois at Urbana-Champaign, takes into account clathrates, which are molecular-sized cages of a compound that can contain many other molecules.
Hydrates also go by the name of clathrates, a term derived from the Latin word for lattice.
