bulk electrolyte, attributing this trend to the solvophobic nature of the graphene surfaces. Further work has observed more complex, non-monotonic trends in transport, in which the conductivity and ion diffusion coefficients can either be greater or less than that of the bulk electrolyte depending on the degree of confinement. It was suggested in this work that the ordered layering of water in confinement enhances ion transport, but that this effect can be counteracted in some slit heights by changes to ion solvation and pairing.
