Fig. 4: Helium permeation through edge-activated graphene nanopores.
From: Edge-activated graphene nanopores for thermally robust hydrogen membrane separations
a projected permeable pore size distribution of graphene nanopores decorated with different edge functional groups as a function of temperature. Different nanopores are named as pore size (number of carbon atoms removed from graphene lattice), followed by the type of functional group and location of the functional group. b helium permeance through graphene nanopores with different edge functional groups. The error bars represent 95% confidence interval for the helium traverse rate across a graphene nanopore. Source data are provided as a Source Data file.
