Permeation of nanopores by water: the effects of channel polarization

Molecular dynamics simulations are used to characterize the permeation by water of cylindrical nanopores, modelling ion channels, as a function of channel radius R and dielectric permittivity is an element of. Intermittent permeation is found in a narrow range around the threshold values of R and is an element of. While channel permeation is highly sensitive to channel polarization effects, no effect on structural properties of the confined water is found on varying is an element of.
