High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

open access: yesAdvanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

open access: yesAdvanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Robust, Breathable and Stretchable Liquid Metal Composite Nanofibre for Physiological Electrical Signal Monitoring

open access: yesAdvanced Science, EarlyView.
A conductive TPU/liquid‐metal nanofibrous film is fabricated via ultrasonic dispersion, electrospinning, and mold imprinting. The film is breathable, stretchable, deformation‐stable, and provides electromagnetic shielding. n‐Butanol encapsulation mitigates liquid‐metal surface tension and improves biocompatibility. Stable ECG, EOG, EEG, and EMG signals

Synergistic Mechano‐Fluidic Self‐Fusion of Poly(Vinyl Alcohol)‐Modified Liquid‐Metal Particles for Post‐Treatment‐Free Soft Electronics

open access: yesAdvanced Science, EarlyView.
Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential
