Modeling the Jovian subnebula: II - Composition of regular satellites ices
, 2005 We use the evolutionary turbulent model of Jupiter's subnebula described by Alibert et al. (2005a) to constrain the composition of ices incorporated in its regular icy satellites.

Investigation of the influence of polyelectrolytes hydrodynamic properties on the hydrate formation process [PDF]
, 2018 One of the most perspective non-traditional sources of hydrocarbon raw materials and energy is gas hydrates (GH), which stimulates their large-scale study in many laboratories and scientific centers around the world.

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate
Advanced Science, EarlyView.We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Raman spectroscopic studies of hydrogen clathrate hydrates [PDF]
The Journal of Chemical Physics, 2009 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 H2 molecules. The complex vibron region of the Raman spectrum has been interpreted by observing the change in population of these bands with ...

The Ice Cap Zone: A Unique Habitable Zone for Ocean Worlds
, 2018 Traditional definitions of the habitable zone assume that habitable planets contain a carbonate-silicate cycle that regulates CO2 between the atmosphere, surface, and the interior.

Polymorphism in Br2 Clathrate Hydrates [PDF]
The Journal of Physical Chemistry A, 2008 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.

Planetesimal Compositions in Exoplanet Systems [PDF]
, 2012 We have used recent surveys of the composition of exoplanet host stars to investigate the expected composition of condensed material in planetesimals formed beyond the snow line in the circumstellar nebulae of these systems.

BaIr2Si9: A Hybrid Structure Bridging Sodalite, Clathrate, and Skutterudite Patterns
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.BaIr2Si9 is a p‐type semiconductor combining structural features of the solalithe, clathrate, and skutterudite type of structure. The cage compound BaIr2Si9 adopts the BaRh2Si9 structure type with space group C2/c (Pearson symbol mC48, a = 6.230(1) Å, b = 21.409(3) Å, c = 6.232(1) Å, β = 90.30(1)°).

The Dual Origin Of The Nitrogen Deficiency In Comets: Selective Volatile Trapping In The Nebula And Postaccretion Radiogenic Heating [PDF]
, 2012 We propose a scenario that explains the apparent nitrogen deficiency in comets in away that is consistent with the fact that the surfaces of Pluto and Triton are dominated by nitrogen-rich ice.
