Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

open access: yesAdvanced Science, EarlyView.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...

Interconnected Hierarchically Porous Graphene‐Based Membrane Electrode for High‐Power and Long‐Cycle Lithium–Oxygen Battery

open access: yesAdvanced Science, EarlyView.
Lithium–oxygen batteries face an energy‐power trade‐off due to sluggish O2 transport and pore clogging by Li2O2. Simulations show that reducing tortuosity via interconnected macropores enhances oxygen mobility. A freestanding graphene electrode having interconnected macropores with low tortuosity delivers >2500 mAh g−1, stable lean‐electrolyte cycling,

An All‐Soft Wearable Electrochemiluminescence Chip for Sweat Metabolite Detection

open access: yesAdvanced Science, EarlyView.
A wearable electrochemiluminescence chip for sweat metabolite monitoring is pioneered, integrating “all‐soft” components: a flexible closed bipolar electrode (c‐BPE) array based on laser‐induced graphene (LIG), a laser‐cut microfluidic layer for sweat collection, and deep eutectic solvents (DES)‐based conductive ionogels for ECL emission.
