Abstract: Abstract In this study, a flat-sheet polyamide thin film composite (TFC) membrane with different surface charges has been designed as a forward osmosis (FO) membrane while a positively-charged organic chitooligosaccharide (COS) applied as a draw… read more here.

Abstract: We theoretically demonstrate the possibility of inversion of solvent migration in charged membranes, opposing osmosis. Inversion of solvent migration is ascribed to the finite volume of ions in the solution permeating the membrane, a quantity… read more here.

Abstract: Proton relay between interfacial water molecules allows rapid two-dimensional diffusion. An energy barrier, ΔGr‡, opposes proton-surface-to-bulk release. The ΔGr‡-regulating mechanism thus far has remained unknown. Here, we explored the effect interfacial charges have on ΔGr‡’s… read more here.

DOI: 10.3390/ijms24010034
Abstract: Artificial ion-exchange and other charged membranes, such as biomembranes, are self-organizing nanomaterials built from macromolecules. The interactions of fragments of macromolecules results in phase separation and the formation of ion-conducting channels. The properties conditioned by… read more here.
