a projected permeable pore size distribution of graphene nanopores due to thermal fluctuation at temperature of 300 K as a function of number of carbon atoms removed from graphene lattice. b helium permeance of graphene nanopores with varying sizes as a function temperature. The error bars represent the 95% confidence interval for the helium traverse rate across a graphene nanopore (see details in Methods). c permeable pore size distribution of graphene nanopores, namely Pore_10, Pore_14, and Pore_20 at 300 K, 400 K, and 500 K. The number at the top left of (b) indicates the multiplication factor (e.g., 1e-6) applied to the y-axis values. Source data are provided as a Source Data file.
