1. Biology Having a latticelike structure or appearance: clathrate scales.
2. Chemistry Of or relating to inclusion complexes in which molecules of one substance are completely enclosed within the crystal structure of another.
n. Chemistry
A clathrate compound, such as methane hydrate.

[Latin clāthrātus, past participle of clāthrāre, to furnish with a lattice, from clāthrī, clātra, lattice, from Greek klēithra, pl. of klēithron, door bar, from kleiein, to close.]

[C17: from Latin clāthrāre to provide with a lattice, from Greek klēthra, from klaithron a bar]


(ˈklæθ reɪt)

1. Biol. resembling a lattice; divided or marked like latticework.
2. a substance in which a molecule of one compound fills a cavity within the crystal lattice of another compound.

For example, permafrost--thick subsurface layer of soil that remains frozen year-round--and frozen methane deposits in the seabed, known as methane hydrates or clathrates, are critically important parts of the cryosphere and hence the climate system.
The gas molecules (guests) become trapped in water cages (hosts), also known as clathrates, at high pressures and low temperatures.
The team found that, at the high pressures expected in the moon's ocean, icy materials called clathrates could form that imprison methane molecules within a crystal structure of water ice.
Different sources have been discussed for younger Phanerozoic events, including quick release of methane from dissociation of clathrates, rapid heating of organic matter by volcanic intrusions, or a combination of different factors (for references see Saltzman & Thomas 2012).
The aim of this work is the investigation of the mechanical conversions of natural gas aquatic clathrates, as well as the scale and ways of the chemical conversions of the hydrocarbons in the process of the mechanical activation of gas hydrates.
Three types of minerals are formed depending of the fluid's evolution: water ice, clathrates of carbon dioxide and very hydrated magnesium sulfates (epsomite, meridianiite).
Topics include bulk nanocomposites of thermoelectric materials, thermoelectric inverse clathrates, polymer thermoelectric materials, heat dissipaters, and medical applications.

Warming ocean water to a depth of 3000 meters, [up arrow] resulting in release of seabed methane-bearing temperature clathrates as amplifying feedback of climate [right arrow] change.
Studies measuring isotopes of carbon, conducted by an international team of scientists, including CSIRO, have shown that methane clathrates were not responsible for the large and rapid increase in methane when temperatures rose at the end of the last ice age (12 000 years ago).
As understanding and awareness of how current energy use affects local, regional and global environment and politics, the need for more renewable and sustainable energy supplies and greater energy-use efficiency becomes increasingly apparent, even though huge fossil resources remain -- especially as coal but also as oil sands, oil shales, methane clathrates and other unconventional sources (Rogner 1997).
