From: Air separation with graphene mediated by nanowindow-rim concerted motion

Nanowindows NW-2.97 and NW-2.73 effectively separate air. Temperature dependence for the various parameters in a NW-2.97 and b NW-2.73. Optimum rates occur at a temperature with both high kinetic energy and high adsorption amounts. For calculation of GPU (10−6 cm3 (STP) cm−2 s−1 cm Hg−1), the ideal gas pressure was estimated from the density of the gas far from the surface where it behaves as bulk
