H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

Advanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

Trace Ru‐Doped PtCuRu@PtRu Core‐Shell Electrocatalyst for CO‐Resilient Methanol Oxidation

Advanced Science, EarlyView.
We engineered a trace Ru‐doped PtCuRu@PtRu core‐shell nanostructure. This design exploits lattice mismatch‐induced compressive strain between the PtCuRu ternary core and trace Ru‐doped Pt‐rich shell, systematically downshifting the Pt d‐band center to weaken *CO adsorption energetics.

Mn‐Induced Support Stabilization and Ir Electronic Activation Enable Acid‐Stable, Low‐Loading IrO2 Water Oxidation

Advanced Science, EarlyView.
This study introduces a dual‐regulation strategy utilizing a Mn‐doped Co3O4 support to enhance the activity and stability of low‐loading IrO2 catalysts for acidic water oxidation. Mn induces strong Mn─O covalency to reinforce the spinel lattice and activates Ir sites via interfacial electron transfer.

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

Advanced Science, EarlyView.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

Mixed‐Coordination Electrolytes With Molecular Additives for Robust Interphases in High‐Voltage Rechargeable Magnesium Batteries

Advanced Science, EarlyView.
A mixed‐coordination electrolyte (MCE) combined with a molecular additive (MCE‐MA) promotes pseudo ion pair (pIP) formation within a solvent‐separated ion pair (SSIP)–rich environment, enabling a robust interphase that significantly improves the cycle performance of high‐voltage rechargeable magnesium batteries (RMBs).
