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

open access: yesAdvanced 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

Scalable Multilayer PTFE‐Reinforced Membranes for Durable, High‐Current‐Density Hydroxide Exchange Membrane Water Electrolysis in Dilute Alkali

open access: yesAdvanced Science, EarlyView.
Low‐Tg HEMs are designed to improve membrane‐electrode adhesion by promoting intimate contact with catalyst layers. After hydration, the membrane develops a hydrogel‐like network that supports water uptake and ion transport while retaining mechanical robustness.

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

open access: yesAdvanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Correlated Polymer‐Proton Hopping Enables Water‐Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes

open access: yesAdvanced Science, EarlyView.
A polymer chain in motion: backbone, ring, and counterion dynamics interlock across timescales to relay protons through poly(ionic liquid) membranes. ABSTRACT Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell ...

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

open access: yesAdvanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional
