Abstract

Understanding water transport through nanochannels is central to biology, separations and clean water. Here, the authors show transport of water vapor through Angstrom-scale pores (~2.8–6.6 Å in diameter) in atomically thin graphene membranes is orders of magnitude faster than liquid water, due to permeation occurring in different flow regimes.
