Sampson's theory for hydrodynamic resistance across a zero-length orifice was developed over a century ago. Although a powerful theory for entrance/exit resistance in nanopores, it lacks accuracy for relatively small-radius pores since it does not account for the molecular interface chemistry. Here, Sampson's theory is revisited for the finite slippage and interfacial viscosity variation near the pore wall. The corrected Sampson's theory can accurately predict the hydrodynamic resistance from molecular dynamics simulations of ultrathin nanopores.6 MoreReceived 19 February 2020Accepted 1 October 2020DOI:https://doi.org/10.1103/PhysRevResearch.2.043153Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
