A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects

Advanced Science, EarlyView.
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Bio‐Inspired Internal Stress Engineering for Microscale Surface Cracking in Sensitive Strain Sensors

Advanced Science, EarlyView.
This study presents a bio‐inspired internal stress engineering strategy to fabricate highly sensitive crack‐based strain sensors. By harnessing the internal expansion energy of microspheres and the thickness‐dependent brittle‐to‐ductile transition of ultrathin gold films, tunable microscale cracks are generated.

Overcoming Out‐of‐Plane Conduction by Changing Nanosheet Morphology

Advanced Science, EarlyView.
HTaWO6 membrane made of stacked nanotubes exhibits high out‐of‐plane proton conductivity of 1.7 mS/cm. High current density (1.26 A cm−2) and power density (294 mW cm−2) indicate the potential as a fuel‐cell electrolyte. The morphology‐driven strategy establishes topology engineering as a new design principle for efficient ion transport in two ...

Self‐Responsive Plastron Maintenance on a Superhydrophobic Mesh via Locally Integrated Electrolysis

Advanced Science, EarlyView.
This work presents a self‐switchable SHM‐E surface that enables rapid, autonomous plastron self‐repair and long‐term stability. Plastron loss triggers circuit closure and localized electrolysis, while capillary spreading rapidly restores a continuous plastron and self‐terminates the current.

Stretchable h‐BN/TPU Fibers for Passive‐Active Dual‐Mode Thermal Management and Wearable Haptic Interfaces

Advanced Science, EarlyView.
Optimized 30 wt.% h‐BN/TPU fibers create a thermal conductivity of 2.08 W·m−1·K−1 while retaining mechanical compliance (422% elongation at break). Woven fabrics reduce surface temperature by 5.7°C under simulated solar irradiation. Glove integration enables localized fingertip heating at 29.55°C·s−1 with a thermal relaxation time of approximately 20 s.

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...
