Tetrahydrofuran Clathrate Hydrate Formation [PDF]

open access: yesPhysical Review Letters, 2009
We report on the formation of tetrahydrofuran clathrate hydrate studied by x-ray Raman scattering measurements at the oxygen K edge. A comparison of x-ray Raman spectra measured from water-tetrahydrofuran mixtures and tetrahydrofuran hydrate at different temperatures supports stochastic hydrate formation models rather than models assuming hydrate ...

Structural Flexibility of Water Frameworks: A Single Large Guest‐Inducing Structure‐H and Structure‐II Hydrate Structures

open access: yesSmall Structures
A unique clathrate hydrate system in which a single guest molecule, thiane, induces the formation of both structure‐II (sII) and structure‐H (sH) hydrates under different thermodynamic conditions is reported.

Encapsulation kinetics and dynamics of carbon monoxide in clathrate hydrate. [PDF]

open access: yesNat Commun, 2014
Carbon monoxide clathrate hydrate is a potentially important constituent in the solar system. In contrast to the well-established relation between the size of gaseous molecule and hydrate structure, previous work showed that carbon monoxide molecules ...

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Semi-clathrate hydrate phase stability conditions for methane + TetraButylAmmonium Bromide (TBAB)/TetraButylAmmonium Acetate (TBAA) + water system: Experimental measurements and thermodynamic modeling

open access: yesOil & Gas Science and Technology, 2021
One of the promising applications of clathrate/gas hydrates is the transport and storage of natural gas. Semi-clathrate hydrates have received more attention due to milder pressure/temperature stability conditions compared to ordinary clathrate hydrates.

Hydrogen Hydrate Promoters for Gas Storage—A Review

open access: yesEnergies, 2023
Clathrate and semi-clathrate hydrates have recently been gaining major interest as hydrogen storage material. The benefits of hydrates, such as reversible formation and dissociation, their environmentally friendly nature, economical costs, and lower fire

Enabling hydrate-based methane storage under mild operating conditions by periodic mesoporous organosilica nanotubes

open access: yesHeliyon, 2023
Biomethane is a renewable natural gas substitute produced from biogas. Storage of this sustainable energy vector in confined clathrate hydrates, encapsulated in the pores of a host material, is a highly promising avenue to improve storage capacity and ...

Exploring High-Pressure Transformations in Low-Z (H2, Ne) Hydrates at Low Temperatures

open access: yesCrystals, 2021
The high pressure structural behavior of H2 and Ne clathrate hydrates with approximate composition H2/Ne·~4H2O and featuring cubic structure II (CS-II) was investigated by neutron powder diffraction using the deuterated analogues at ~95 K. CS-II hydrogen
