Methane Hydration‐Shell Structure and Fragility

Angewandte Chemie, 2018
AbstractThe influence of oily molecules on the structure of liquid water is a question of importance to biology and geology and many other fields. Previous experimental, theoretical, and simulation studies of methane in liquid water have reached widely conflicting conclusions regarding the structure of hydrophobic hydration‐shells.

Effects of Submarine Methane-Rich Fluids on Gas Hydrate Production During Depressurization

Journal of Marine Science and Engineering
Submarine methane-rich fluids migrating through geological conduits significantly influence gas hydrate production during depressurization. However, the coupled effects of methane, water, and heat delivered by these fluids on hydrate dissociation and ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Slow Transit Constipation: Pathophysiological Perspectives and Management Updates

Journal of Digestive Diseases, EarlyView.
Slow transit constipation (STC) is a complex neuromuscular disorder driven by interstitial cells of Cajal (ICCs) loss and enteric neuropathy. Diagnosis relies on objective transit testing while excluding pelvic floor dysfunction. Management follows a stepwise, phenotype‐driven approach, progressing from conventional laxatives to emerging targeted ...

Magnetic Mineral Diagenesis in a Newly Discovered Active Cold Seep Site in the Bay of Bengal

Frontiers in Earth Science, 2020
Diagenetically formed magnetic minerals at marine methane seep sites are potential archive of past fluid flow and could provide important constraints on the evolution of past methane seepage dynamics and gas hydrate formation over geologic time.

Experimental Study of Methane Hydrates in Coal

E3S Web of Conferences, 2017
The possibility of gas hydrate formation in porous space of coal has been studied. The experiments conducted have proven the possibility of methane gas hydrate formation in moist coal. It has been demonstrated that the decomposition points of methane gas

Role of tectonic stress in seepage evolution along the gas hydrate‐charged Vestnesa Ridge, Fram Strait [PDF]

, 2015
Methane expulsion from the world ocean floor is a broadly observed phenomenon known to be episodic. Yet the processes that modulate seepage remain elusive.
