Atomistic modeling of structure II gas hydrate mechanics: Compressibility and equations of state
AIP Advances, 2016 This work uses density functional theory (DFT) to investigate the poorly characterized structure II gas hydrates, for various guests (empty, propane, butane, ethane-methane, propane-methane), at the atomistic scale to determine key structure and ...

Freshwater lake to salt-water sea causing widespread hydrate dissociation in the Black Sea
Nature Communications, 2018 Gas hydrates are maintained via a balance of temperature and pressure, if this changes then destabilization may occur. Here, the authors show instead that due to recent changes in the salinity of the sea water of the Black Sea, gas hydrates may become ...

Experimental Measurement of Methane and Ethane Mole Fractions during Gas Hydrate Formation [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2017 The super-saturation condition has to be provided to form gas hydrates. Consequently, the prediction of the guest molecule fraction in the aqueous phase is crucial in the study of the gas hydrate kinetics.

Methane hydrate formation and decomposition
Electronic Journal of Differential Equations, 2009 Methane hydrates, in arctic permafrost and deep ocean sediments, store vast amounts of methane, which is the primary constituent of natural gas and a potent greenhouse gas.

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors
Journal of Applied Polymer Science, Volume 143, Issue 35, September 15, 2026.A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.
