Water occupation number inside the nanopore for a–h 2D and i–l 3D membranes. The membrane–water interaction strengths are 0.25 \({\epsilon }_{0}\) for a, e, and i, 0.5 \({\epsilon }_{0}\) for b, f, and j, \({\epsilon }_{0}\) for c, g, and k, and 4 \({\epsilon }_{0}\) for d, h, and l. Average occupation numbers vary with the interaction strength (m)
