Nanoporous membranes based on two dimensional materials are predicted to provide highly selective gas transport in combination with extreme permeance. Here we investigate made from multilayer graphdiyne, a graphene-like crystal larger unit cell. Despite being nearly hundred of nanometers thick, the allow fast, Knudsen-type permeation light gases such as helium and hydrogen whereas heavy noble like xenon exhibit strongly suppressed flows. Using isotope cryogenic temperature measurements,...

Osmotic power extracts electricity from salinity gradients and provides a viable route toward clean energy. To improve the energy conversion efficiency, common strategies rely on fabricating precisely controlled nanopores to meet requirements of high ionic conductivity selectivity. We report ion transport through free-volume networks in stacked polymer nanospheres for osmotic harvesting. Such nanospheres, composed coiled poly(acrylic acid) molecules, are synthesized at an ice–liquid...

Fast ion permeation in nanofluidic channels has been intensively investigated the past few decades because of their potential uses separation technologies and osmotic energy harvesting. Mechanisms governing transport at this ultimately small spatial regime remain to be understood, which can only achieved nanochannels that are controllably fabricated. Here, we report fabrication two-dimensional with top bottom walls consisting atomically flat graphite mica crystals, respectively. The distinct...

In nature and technologies, many chemical reactions occur at interfaces with dimensions approaching that of a single reacting species in nano- angstrom-scale. Mechanisms governing this ultimately small spatial regime remain poorly explored because challenges to controllably fabricate required devices assess their performance experiment. Here we report how efficiency electrochemical evolves for electrodes range from just one atom thickness sizes comparable exceeding hydration diameters...

Abstract In nature and technologies, many chemical reactions occur at interfaces with dimensions approaching that of a single reacting species in nano‐ angstrom‐scale. Mechanisms governing this ultimately small spatial regime remain poorly explored because challenges to controllably fabricate required devices assess their performance experiment. Here we report how efficiency electrochemical evolves for electrodes range from just one atom thickness sizes comparable exceeding hydration...
