Adhesive Double‐Network Granular Organogel E‐Skin
Advanced Materials Technologies, EarlyView.We introduce a double‐network granular organogel adhesive for electronic skin, overcoming adhesion and strength trade‐offs. It provides reversible, robust bonding and ionic conductivity, enabling wearable and soft robotic e‐skin. Thanks to the e‐skin adhesive, a soft robotic trunk can recognize touch, temperature, humidity, and acidity.

Advanced Theory and Simulations, EarlyView.Six functionalized TpPa‐based covalent organic frameworks (COFs) are characterized using nonequilibrium molecular dynamics simulations to assess water permeance and salt rejection. The TpPa‐SO3H COF membrane achieves the highest sodium sulfate rejection (>98%) while maintaining relatively high water permeance compared to commercial nanofiltration ...
