Icephobicity of Functionalized Graphene Surfaces

The rational nanostructuring of surfaces for extraordinary icephobicity

1. Thermodynamic Relations and Poisson Statistics The thermodynamically guided tailoring of surface morphologies aims at depressing the heterogeneous ice nucleation rate by unfavorable thermodynamic conditions stemming from the surface/droplet interaction. The theoretical framework for this surface morphology tailoring can be established by invoking the use of the classical heterogeneous nuclea...

Functionalized Graphene Nanocomposites

Spectroscopy of covalently functionalized graphene.

In order to engineer a band gap into graphene, covalent bond-forming reactions can be used to change the hybridization of the graphitic atoms from sp(2) to sp(3), thereby modifying the conjugation length of the delocalized carbon lattice; similar side-wall chemistry has been shown to introduce a band gap into metallic single-walled carbon nanotubes. Here we demonstrate that the application of s...

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 ...
