Precise Control of Charge–Structure Coupling in Polyamide Membranes for Mono‐ and Divalent Ion Separation

Advanced Science, EarlyView.
A zwitterionic copolymer, Poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐2‐aminoethyl methacrylate hydrochloride) (P(MPC‐co‐AEMA)) copolymers, with tunable MPC/AEMA ratios, is grafted onto the polyamide (PA) selective layer via secondary interfacial polymerization. Balancing reactive anchoring segments (AEMA) and zwitterionic segments (MPC) regulated

Membrane‐aided simultaneous reaction–separation for liquid phase products

AIChE Journal, EarlyView.
Abstract Conventionally, reaction and separation are conducted as separate steps in liquid‐phase manufacturing, with products formed during reaction and subsequently separated from unreacted reagents, solvents, and byproducts. Integrating these steps into a simultaneous reaction–separation process can improve efficiency and reduce costs.

Hierarchische Membran zur photoelektrostatisch gesteuerten Trennung ein‐ und zweiwertiger Ionen

Angewandte Chemie, EarlyView.
Wir berichten über eine hierarchische, auf anodischem Aluminiumoxid getragene Poly(ionische Flüssigkeit)‐Kohlenstoffnitrid‐Membran zur effizienten Trennung ein‐ und zweiwertiger Ionen. Räumlich begrenzte Nanokanäle und gezielt eingestellte Ion‐Grenzflächen‐Wechselwirkungen ermöglichen außergewöhnlich hohe K+/Mg2+‐ (>500) und Li+/Mg2+‐Selektivitäten ...

Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation

Angewandte Chemie International Edition, EarlyView.
We report a hierarchical poly(ionic liquid)–carbon nitride membrane supported on anodic alumina for efficient monovalent/divalent ion separation. Confined nanochannels and tailored interfacial ion interactions enable exceptional K+/Mg2+ ( > 500) and Li+/Mg2+ ( > 200) selectivities, offering a promising strategy for advanced aqueous ion separations ...
