The Optical Measurement of CO2 Clathrate Hydrate Membrane Thickness

Journal of Thermal Science and Technology, 2007
The technology of the deep-ocean CO2 storage is expected to directly mitigate the source of the global warming. At deep-ocean condition above 4.45 MPa and below 283 K, the CO2 clathrate hydrate crystals are formed as membrane at the interface between the

Methane clathrate hydrate infrared spectrum [PDF]

Astronomy and Astrophysics, 2010
Context. Recently, we recorded the infrared spectrum of the methane clathrate hydrate stretching mode at low temperature, a caged compound of possible interest for solar system studies as well as interstellar ice mantles.Aims. We provide a practical infrared spectroscopic identification for methane clathrate hydrate to examine its astrophysical ...

Phonon-glass electron-crystal thermoelectric clathrates: Experiments and theory [PDF]

, 2014
Type-I clathrate compounds have attracted a great deal of interest in connection with the search for efficient thermoelectric materials. These compounds constitute networked cages consisting of nano-scale tetrakaidecahedrons (14 hedrons) and ...

Zero-point energy effects on the stability of water clusters: Implications on the uptake of hydrogen isotope substituted water on ice and clathrate hydrate phases

AIP Advances
To study the effect of hydrogen isotope substitution on the uptake of water during formation of clathrate hydrates, the harmonic intermolecular librational modes of selected water clusters (X2O)n with n = 2–6 and hydrogen isotopes X = H, D, and T are ...

Enhanced Selectivity of the Separation of CO2 from N2 during Crystallization of Semi-Clathrates from Quaternary Ammonium Solutions

Oil & Gas Science and Technology, 2014
CO2 mitigation is crucial environmental problem and a societal challenge for this century. CO2 capture and sequestration is a route to solve a part of the problem, especially for the industries in which the gases to be treated are well localized.

Lateral growth of xenon hydrate films on mica

AIMS Materials Science, 2021
In this paper, we report an in situ optical microscopy study of lateral growth of xenon (Xe) hydrate thin films on mica at sub-zero temperatures. The interactions between a solid surface and water molecules can strongly affect the alignment of water ...

Non-Fickian Diffusion Affects the Relation between the Salinity and Hydrate Capacity Profiles in Marine Sediments [PDF]

, 2012
On-site measurements of water salinity (which can be directly evaluated from the electrical conductivity) in deep-sea sediments is technically the primary source of indirect information on the capacity of the marine deposits of methane hydrates.

Early Mars volcanic sulfur storage in the cryosphere and formation of transient SO2-rich atmospheres during the Hesperian

, 2016
In a previous paper (Chassefi\`ere et al., Icarus 223, 878-891, 2013), we have shown that most volcanic sulfur released to early Mars atmosphere could have been trapped in the cryosphere under the form of CO2-SO2 clathrates. Huge amounts of sulfur, up to

Exploring the role of silver nanoparticles and surfactants in gas hydrate formation: a study on structural dynamics [PDF]

E3S Web of Conferences
This study explores how silver nanoparticles (5Å in diameter), SDS affect carbon dioxide hydrate formation, particularly their role in speeding up the creation of clathrate hydrates. The research highlights the importance of nanoparticles and surfactants

Investigation on the Synergistic Effect of Tetra Butyl Phosphonium Bromide with Poly(N-isopropylacrylamide) Based Kinetic Hydrate Inhibitor

Chemical Engineering Transactions, 2020
The problem of clathrate hydrate plugging in flow pipes has been the most important issue in the off-shore exploitation since hydrates were found in transport facilities.
