Strain-induced stabilization of Al functionalization in graphene oxide nanosheet for enhanced NH3 storage

Application of Functionalized Graphene Oxide Nanosheet in Gas Separation

   Graphene oxide nanosheet (GONS) can be a suitable membrane for gas separation with high permeability and selectivity. Separation of N2/CO2 using functionalized GONS was investigated by molecular dynamics simulations. The simulated systems were comprised of two types of GONS with a pore in their center, N2 and CO2 molecules. The selectivity and ...
