(a) Permeability of R-BAPB with respect to CH4, N2, O2, and He at T = 300 K. (b) Selectivity of R-BAPB for various gas pairs at T = 300 K, obtained in molecular dynamics simulations and in experiment. The results obtained in molecular dynamics simulations are shown by the shaded columns, and experimental data are given in the solid columns. Semi-logarithmic axes.
