Methane 72-79 transcription elongation factor A1 Homo sapiens 67-71 32441519-6 2020 CO2 and N2 were not complementary but competitive in replacing CH4 in the small (512) cages, which contributed to maintenance of the cage stability of the initial sII hydrate and, thus, resulted in a lower extent of replacement. Methane 63-66 transcription elongation factor A1 Homo sapiens 163-166 32441519-1 2020 This study investigated structural transformation, guest distributions, and the extent of replacement for CH4+C3H8 - flue gas replacement occurring in sII hydrates via gas chromatography, NMR spectroscopy, and powder X-ray diffraction (PXRD).

Methane 183-190 transcription elongation factor A1 Homo sapiens 216-220 24619231-4 2014 With two exemplary cores we demonstrate that the dissolution of particulate Fe and Mn is coupled to the anaerobic oxidation of CH4 (AOM) either via the reduction of sulphate (SO4(2-)) and the subsequent generation of Fe(II) by S(-II) oxidation, or directly coupled to Fe reduction. Methane 127-130 transcription elongation factor A1 Homo sapiens 227-232 27782458-3 2016 In particular, molecular dynamics simulations with accurate water potentials are used to study the energetics of the formation of structure I (sI) and II (sII) clathrate hydrates of methane, ethane, and propane. Methane 182-189 transcription elongation factor A1 Homo sapiens 155-158 27782458-5 2016 The encapsulation energies of methane, ethane, and propane guests stabilize the small and large sI and sII hydrate cages, with the larger molecules giving larger encapsulation energies. Methane 30-37 transcription elongation factor A1 Homo sapiens 103-106 26156457-2 2015 Here, we present potential mechanisms for the interconversions between sI and sH and sII and sH, as observed within molecular simulations of the cross-nucleation of different methane hydrate phases.

Binary mixed-gas hydrates including methane and other guest gases demonstrate a structural transition between the sI and sII phases. Methane 130-137 transcription elongation factor A1 Homo sapiens 215-218 22627268-1 2012 Under increasing pressure pure methane hydrate exhibits a phase transition first from sI to sII and then to sH. Methane 31-38 transcription elongation factor A1 Homo sapiens 92-95 22627268-3 2012 Recently, molecular dynamics simulations of methane hydrates suggest there may exist uncommon 15-hedral cages (51263), linking the sI and sII cages. Methane 44-51 transcription elongation factor A1 Homo sapiens 138-141 20646941-1 2010 Clathrate hydrates formed from binary gas mixtures of methane and other small lipophilic molecules change from the sI phase to sII and back depending on the concentration of methane in the mixtures.

Methane 174-181 transcription elongation factor A1 Homo sapiens 127-130 20646941-2 2010 In contrast, pure methane hydrate under increasing pressure transforms first from sI to sII and then finally to sH. Methane 18-25 transcription elongation factor A1 Homo sapiens 88-91 19209919-3 2009 The observed faster structural conversion rate in the higher methane concentration atmosphere can be explained in terms of the differences in driving force (difference in chemical potential of water in sI and sII hydrates) and kinetics (mass transfer of gas and water rearrangement). Methane 61-68 transcription elongation factor A1 Homo sapiens 209-212 19209919-4 2009 The kinetic hydrate inhibitor increased the conversion rate at 65% methane in ethane (sI is thermodynamically stable) but retards the rate at 93% methane in ethane (sII is thermodynamically stable), implying there is a complex interaction between the polymer, water, and hydrate guests at crystal surfaces.
