Molecular Simulations of Methane Hydrate Nucleation

ChemPhysChem, 2010
Gas hydrates have been known for 200 years or more and the nature of these interesting solids remained hidden until crystallographic studies some 140 years later revealed that they were crystalline guest–host materials classified as clathrates. [1] The discovery of vast quantities of natural gas hydrate in sediment offshore on the continental margins ...

Mechanistic insights into a hydrate contribution to the Paleocene-Eocene carbon cycle perturbation from coupled thermohydraulic simulations [PDF]

, 2016
During the Paleocene-Eocene Thermal Maximum (PETM), the carbon isotopic signature (δ13C) of surface carbon-bearing phases decreased abruptly by at least 2.5 to 3.0‰.

Mechanisms of Methane Hydrate Formation in Geological Systems

Reviews of Geophysics, 2019
Natural gas hydrate is ice‐like mixture of gas (mostly methane) and water that is widely found in sediments along the world's continental margins and within and beneath permafrost and glaciers in a near‐surface depth interval where the pressure is ...

Insights into the Controlled Formation of Zr‐Based Metal–Organic Gels: Linking Macroscopic Properties with Molecular Information from Solution State NMR

Angewandte Chemie, EarlyView.
Real time STD/SDTD NMR unveils water structuring during UiO‐66 gelation under mild, acid‐free conditions compatible with biomolecule encapsulation. This approach bridges molecular‐scale solvent ordering with macroscopic gel properties, unlocking mechanistic insight for the rational design of MOF gels.

Transport- reaction modeling of marine gas hydrate deposits- global results [PDF]

, 2011
We have developed a multi-1D numerical model of gas hydrate formation and dissolution processes in anoxic marine sediments and, by this model, we have estimated the new global gas hydrate inventory (BURWICZ E. B. et al., 2011).
