Trace Sulfur‐Doping Boosts NiCo Heterostructured Catalyst for Selective Glycerol‐to‐Formic Acid Electroreforming

Advanced Functional Materials, EarlyView.
A sulfur‐doped Ni–Co heterostructured catalyst is rationally designed to regulate interfacial electronic and adsorption properties for selective glycerol electrooxidation. The synergistic Ni–Co active sites promote hydroxide activation and glycerol adsorption, enabling efficient formic acid production and durable hydrogen generation under continuous ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Anion‐Exchange‐Enabled Hydrogel Electrolytes With High Zn2+ Transference for Dendrite‐Free Flexible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A high‐Zn2+‐transference hydrogel electrolyte of ex‐PDADAM is developed via anion exchange at quaternary ammonium sites, achieving high Zn2+ transference number (0.86), ionic conductivity (8.10 mS cm−1), and toughness (51.25 MJ m−3). Symmetric cells are operated stably for over 2000 h, while flexible pouch cells retain 90.9% capacity after 300 cycles ...
