Advanced Functional Materials, EarlyView.A novel stratum corneum‐inspired zwitterionic hydrogel is developed for intelligent, flexible sensors, featuring intrinsic water retention and anti‐freezing properties. The quasi‐gel, composed of hygroscopic polymers and bound water, maintains its softness across a wide range of humidity.

Phase field predictions of microscopic fracture and R-curve behaviour of fibre-reinforced composites [PDF]
Composites Science and Technology (2021), 2020 We present a computational framework to explore the effect of microstructure and constituent properties upon the fracture toughness of fibre-reinforced polymer composites. To capture microscopic matrix cracking and fibre-matrix debonding, the framework couples the phase field fracture method and a cohesive zone model in the context of the finite ...

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu
Advanced Functional Materials, EarlyView.Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention
