Thermodynamic stability of hydrogen clathrates.

The stability of the recently characterized type II hydrogen clathrate [Mao, W. L., Mao, H.-K., Goncharov, A. F., Struzhkin, V. V., Guo, Q., et al. (2002) Science 297, 2247-2249] with respect to hydrogen occupancy is examined with a statistical mechanical model in conjunction with first-principles quantum chemistry calculations. It is found that the stability of the clathrate is mainly caused b...

Methane storage in tea clathrates.

Methane can be stored in tea clathrates, that is kinetics of methane clathrate formation can be significantly accelerated (90% saturation uptake in 20 min) by ingredients (polyphenols and saponins) in tea infusions with a volumetric capacity of up to 172 v/v.

Thermoelectric Power Generation by Clathrates

Clathrate compounds combine aesthetic beauty of their crystal structures with promising thermoelectric properties that have made them one of the most explored family of compounds deemed as base for thermoelectric generators for midand hightemperature application. This chapter surveys crystal and electronic structure and structure-related transport properties of selected types of clathrates and ...

Methane clathrates in the solar system.

We review the reservoirs of methane clathrates that may exist in the different bodies of the Solar System. Methane was formed in the interstellar medium prior to having been embedded in the protosolar nebula gas phase. This molecule was subsequently trapped in clathrates that formed from crystalline water ice during the cooling of the disk and incorporated in this form into the building blocks ...

NMR AND COMPUTATIONAL STUDIES OF Ba8Ga16Sn30 CLATHRATES

We report a study of type-VIII and type-I Ba8Ga16Sn30. NMR lineshape measurements identify a broad first-order satellite resonance. Simulations for the type-I structure based on first principles calculations provided an excellent fit to the data, with the best agreement provided by configurations with 4 Ga-Ga bonds. However calculations indicate that preferred configurations should completely a...
