Defect-enabled fast gas hydrate kinetics for energy and decarbonisation applications

Journal of CO2 Utilization
Gas hydrates are gas-carrying water structures with proven relevance to the sustainability future. Nature showcases these gas-carrying water structures through multi-trillion tones of methane encapsulated in natural gas hydrates (NGHs) on Earth ...

Distinct expressions of the BSR using various frequencies offshore Uruguay and its correspondence with the gas hydrate stability zone [PDF]

, 2011
At the Uruguayan continental margin, seismic evidence for the occurrence of gas hydrate has been identified based on the presence of BSRs in densely spaced 2D reflection seismic sections from different surveys.

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

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 ...

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

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 ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

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.

Reactivity of the Iron Complexes with the Macrocyclic Ligand 5,5,7,12,12,14‐Hexamethyl‐1,4,8,11‐Tetraazacyclotetradecane (tet) Toward Dioxygen

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complex [(tet a)FeII(OTf)2] reacts with dioxygen first to a superoxido intermediate and in a consecutive reaction to the corresponding iron–oxido complex. The reactions of the iron complexes [(tet a)FeII(OTf)2] and [(tet b)FeII](OTf)2 (tet = 5,5,7,12,12,14‐hexamethyl‐1,4,8,11‐tetraazacyclotetradecane) with dioxygen were investigated.
