Heteroatom‐Mediated Covalent Organic Framework Membranes With Nitrogen‐Enriched Nanochannels for Efficient Desalination

open access: yesAdvanced Science, EarlyView.
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

A Superstrong and Ultratough Stretchable Electronic Conductor With Ultradurable Strain‐Insensitive Electromechanical Performance

open access: yesAdvanced Science, EarlyView.
We report a superstrong, ultratough, and fatigue‐resistant stretchable electronic conductor (SEC) integrating a viscoplastic quasi‐solid LM‐Ag alloy with a supramolecular elastomer. Unlike conventional LM, the alloy exhibits thixotropic flow, reduced surface tension, and enhanced interfacial interactions with the elastomer.
