Progress and Prospects in Permeation [PDF]

The Journal of General Physiology, 1999
Many laboratories study the movement of ions through single channel molecules every day using the dazzling techniques of molecular and membrane biology. Atomic details of a channel are changed and the correlations of structure and function are observed routinely, but the correlations have ...

Pilot scale study of chlorination-induced transport property changes of a seawater reverse osmosis membrane [PDF]

, 2013
A pilot-scale study was performed to assess variations of reverse osmosis (RO) membrane water permeance (A) and salt retention (Robs) induced by chlorination and to compare them with those observed at the lab-scale. A chlorination protocol was adapted to

Intermittent permeation of cylindrical nanopores by water

, 2002
Molecular Dynamics simulations of water molecules in nanometre sized cylindrical channels connecting two reservoirs show that the permeation of water is very sensitive to the channel radius and to electric polarization of the embedding material.
