Water–charge and water–water interactions. (A and B) The interaction energies of a water molecule at z with the imposed charge, PWC (A), and with the neighbored water molecules, PWW (B), for different radial distance δ. (C) Values of PWC and PWW/2 at z = 0, denoted by PWCC and PWWC, with respect to δ. (D) Decreasing of the average value of flow and the net flux with respect of PWWC − PWCC. Exponential laws can fit the data very well in the interval of 0.25 Å ≤ δ ≤ 0.75 Å.
