Artificial water channels (AWCs) have emerged as a promising framework for stable water permeation, with water transport rates comparable to aquaporins (3.4-40.3 × 10 HO/channel/s).

Article Synopsis
- - The study focuses on the separation of similar-charge ions and explores membranes made from zwitterionic amphiphilic copolymers (ZAC-X) that can selectively allow the passage of different anions, particularly comparing two structural arrangements, Motif A and Motif B.
- - Molecular dynamics simulations were used to analyze how the orientation of zwitterionic ligands affects the movement and selectivity of anions, revealing that Motif A shows less ion pairing while Motif B demonstrates stronger pairing for small anions.
- - Results indicate that the size of anions influences their partitioning and diffusivity, with Motif B showing higher selectivity for larger anions; ultimately, partitioning trends have a greater impact on
Recent experimental results have demonstrated that zwitterionic ionogel comprised of polyzwitterion (polyZI)-supported lithium salt-doped ionic liquid exhibits improved conductivities and lithium transference numbers than the salt-doped base ionic liquid electrolyte (ILE). However, the underlying mechanisms of such observations remain unresolved. In this work, we pursued a systematic investigation to understand the impact of the polyZI content and salt concentration on the structural and dynamic properties of the poly(MPC) ionogel of our model polyZI ionogel, poly(2-methacryloyloxyethyl phosphorylcholine) [poly(MPC)] supported LiTFSI/N-butyl-N-methylpyrrolidinium TFSI base ionic liquid electrolyte.
