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 ...
