Polyzwitterionic Organohydrogel and Soft Composite with Tunable Sol–Gel Properties Enabling On‐Demand Functionalization with Colloids

open access: yesAdvanced Science, EarlyView.
Poly[2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide‐based organohydrogels are formed via nonsolvent‐induced gelation, featuring tunable viscoelasticity. Functional fillers (MXene nanosheets, magnetic NdFeB microparticles) enable electrical, magnetic, and mechanical responsiveness for applications in mechano‐tunable electromagnetic ...

An Optically Transparent Water‐Based Metamaterial Absorber for Ultra‐Broadband EMI Shielding in Coal Mines

open access: yesAdvanced Science, EarlyView.
This study introduces a novel metamaterial absorber integrating water as a lossy medium with patterned indium tin oxide (ITO) films to achieve simultaneous optical transparency and ultra‐wideband electromagnetic absorption over 0.52‐40 GHz. It effectively overcomes the limitations of conventional opaque and bulky shielding materials, offering a ...

Tough and Temperature‐Resistant Material Based on Bombyx mori Silk Fibroin

open access: yesAdvanced Science, EarlyView.
We propose a biomimetic “Hydration‐Crystallization Locking” (HCL) strategy inspired by Bombyx mori spinning to enhance silk fibroin (SF) performance in extreme temperatures. A flexible fibroin membrane (FFM) shows high strength, toughness, and shape retention under −196°C and 70°C.
