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

Decoding Interfacial Polymerization Through Steady Amine Delivery and Real‐Time QCM‐D Monitoring

Advanced Science, EarlyView.
We combine steady amine delivery with in situ quartz crystal microbalance with dissipation to track interfacial polymerization in real time. The platform resolves three kinetic regimes: pre‐gelation oligomerization, post‐gelation aggregation and network growth, and diffusion‐limited film evolution.

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.

Stripping‐based approach for the recovery of volatile fatty acids from anaerobic digestion digestate: preliminary experimental investigations and modelling

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Volatile fatty acids (VFAs) are widely used across industries: as intermediates in chemical production (e.g., solvents and polymers), in pharmaceuticals and cosmetics, and as preservatives and health‐promoting additives in food and animal feed. Emerging applications also include bioplastics, bioenergy, and biotechnology.
