Novel ionic transporting phenomena emerge as nanostructures approach the molecular scale.At the sub-2 nm scale,widely used continuum equations,such as the Nernst-Planck equation,break down.Here,we extend the Nernst-Planck equation by adding a partial dehydration effect.Our model agrees with the reported ion fluxes through graphene oxide laminates with sub-2 nm interlayer spacing,outperforming previous models.We also predict that the selectivity sequences of alkali metal ions depend on the geometries of the nanostructures.Our model opens a new avenue for the investigation of the underlying mechanisms in nanofluidics at the sub-2 nm scale. 展开更多
