Raman Spectroscopic Study on a CO2-CH4-N2 Mixed-Gas Hydrate System

Frontiers in Energy Research, 2021
Accurate determination of the characteristics of coal mine gas separation products is the key for gas separation applications based on hydrate technology. Gas hydrates are synthesized from gases with two types of compositions (CO2-CH4-N2). The separation

Graphane: a two-dimensional hydrocarbon [PDF]

, 2006
We predict the stability of an extended two-dimensional hydrocarbon on the basis of first-principles total-energy calculations. The compound that we call graphane is a fully saturated hydrocarbon derived from a single graphene sheet with formula CH.
