In the area of air conditioning, the tetra-n-butyl-ammonium bromide (TBAB) clathrate hydrate slurry (CHS) is a promising high-density latent-heat carrying medium.
All of the cages are not necessarily dependent on the temperature and the pressure of the guest compound in equilibrium with clathrate hydrate.
The fruits of these efforts are disseminated through the NIST Sandard Reference Data Program [1] as the Clathrate Hydrate Physical Property Database (SRD #156).
The book's four chapters cover clathrate hydrate crystallization for clean energies, mitigating corrosion in tropical climates, the application of D-statistics based tests of randomness and trend to electrochemical observations, and the preparation of multiblock copolymers with self-assembly assisted polypolymerization (SAAP).
This third edition contains information on clathrate hydrate compounds discovered in the past 10 years, and offers new material on structure, kinetics, and prediction methods, new phase equilibrium data and kinetic models, and new computer programs used in the field.
In other words, clathrate hydrates are clathrate compounds in which the host molecule is water and the guest molecule is typically a gas or liquid.
Among the topics are pressure-driven liquid-liquid transformations and corresponding bizarre viscosity behavior, the water proton environment as a possible new water anomaly at the atomic scale, water and biological macromolecules, water-like thermodynamics and dynamic anomalies and the evidence for polymorphism in computer simulations of liquid silica, and a statistical mechanical approach to the thermodynamic stability of clathrate hydrates.
Clathrate hydrates form when water molecules crystallize into a cage-like structure that can contain one or more molecules of natural gas or other hydrocarbons.
Clathrate hydrates are not chemical compounds, as the sequestered molecules are never bonded to the lattice.
Clathrate hydrates (or gas hydrates) are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside 'cages' of hydrogen bonded water molecules.
The 89th edition continues the format of the past, with new tables added for atomic radii, composition and properties of common oils and fats, global warming potential of greenhouse gases, weather-related scales, energy content of fuels, properties of gas clathrate hydrates, melting curve of mercury, enthalpy of hydration of gases, and electrical resistivity of graphite materials.
Clathrate hydrates are ice-like inclusion complexes between small, usually gaseous guests and crystalline water hosts.
