Site‐Specific Hydroxide Formation and Corrosion on Mg Nanocrystals

Advanced Science, EarlyView.
Using single‐crystalline Mg nanocrystals, this study uncovers the intrinsic corrosion initiation mechanism. The stability of the protective Mg(OH)2 film depends on its interfacial coherence with the Mg substrate. Corrosion initiates at exposed corners, where film coverage is incomplete.

In Situ Stress‐Dispersing Hydrogel Millispheres via Load Redistribution to Restore Nucleus Pulposus Metabolic Homeostasis

Advanced Science, EarlyView.
Local stress concentration disrupts metabolic homeostasis and induces inflammation in the nucleus pulposus (NP), thereby accelerating intervertebral disc degeneration (IDD). A biomimetic HA/ChS hydrogel millimeter sphere (ChS@HM) is developed to enable synergistic stress dispersion and sustained hydration lubrication.

Dual‐Network Protein Hydrogels Promote Rapid Hemostasis and Immune‐Regulated Scarless Tissue Regeneration

Advanced Science, EarlyView.
A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.

Self‐Powered Bearing Sensing and Real‐Time Fault Diagnosis Enabled by Non‐Invasive Triboelectric Sensors and Edge AI Acceleration

Advanced Science, EarlyView.
This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...

Integrated Hydrophilic Interdigitated Network for Silicone Rubber via a Gradient Polarity Modification Strategy

Advanced Science, EarlyView.
This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.
