要旨

We investigated the effect of the electric field on single-file reverse osmosis (RO) water flux using molecular dynamics simulations. The electric field is generated by introducing oppositely charged biomolecules to the salt solution and pure water chambers attached to the nanopore. Simulation results indicate that an electric field in the direction of RO enhances the water flux while in the direction opposite to RO it suppresses the water flux. When the RO water flux is enhanced, the single-file water dipoles are aligned in the direction of the electric field. The addition of an electric field in the direction of RO led to a flux of 3 water molecules ns−1 by constantly maintaining water dipole vectors in the direction of the electric field, and this water flux is superimposed on the pressure driven water flux.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
