On the volatile enrichments and composition of Jupiter [PDF]

, 2005
Using the clathrate hydrates trapping theory, we discuss the enrichments in volatiles in the atmosphere of Jupiter measured by the \textit{Galileo} probe in the framework of new extended core-accretion planet formation models including migration and disk

Crystallographic analyses of clathrate hydrates included in Vostok ice cores

Antarctic Record, 1992
Purpose and methods of crystallographic analyses of clathrate hydrates included in ice cores recovered at Vostok, Antarctica are briefly reviewed. The clathrate hydrate is a crystal composed of a cage structure formed by water molecules, and includes ...

Promoting the Insertion of Molecular Hydrogen in Tetrahydrofuran Hydrate With the Help of Acidic Additives

Frontiers in Chemistry, 2020
Among hydrogen storage materials, hydrogen hydrates have received a particular attention over the last decades. The pure hydrogen hydrate is generated only at extremely high-pressure (few thousands of bars) and the formation conditions are known to be ...

Structural Identification of Binary Tetrahydrofuran + O2 and 3-Hydroxytetrahydrofuran + O2 Clathrate Hydrates by Rietveld Analysis with Direct Space Method

Crystals, 2018
The structural determination of clathrate hydrates, nonstoichiometric crystalline host-guest materials, is challenging because of the dynamical disorder and partial cage occupancies of the guest molecules.
