Sodium Ascorbate‐Accelerated Gelling Hydrogels With Rapid Self‐Mineralized Capacity for Chronic Wounds

Advanced Science, EarlyView.
An immunoregulatory hydrogel based on sodium ascorbate (SA)‐accelerated gelation and in situ self‐mineralization is prepared here. Such a hydrogel is constructed by mixing benzaldehyde‐ and cyanoacetate‐functionalized dextran with silver nitrate (AgNO3) and SA, enabling the ultrafast solidification and in situ self‐mineralization of silver ...

Metal‐Support Interaction Triggered Electronic Reconstruction in Pd/CoN‐Co4N Catalysts for Optimizing MEK Oxidation and Poisoning Resistance

Advanced Science, EarlyView.
The strengthened EMSI in Pd/CoN‐Co4N induces electronic rearrangement, generating abundant Pd0 species in situ, modulating the Pd d‐band center to enhance O2 adsorption and MEK activation. Concurrently, it creates numerous Lewis acid sites that preferentially adsorb poisons and shield the active sites.

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

Advanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Atomic‐Level CuOx‐CoOx‐Pd Interfacial Engineering Enables Hierarchical Synergy for High‐Efficiency ORR Pathways and Boosted Power Output in Alkaline Fuel Cells

Advanced Science, EarlyView.
Atomically dispersed CuOx (CPCu‐1) forms isolated Cu–Ov sites that enable defect‐mediated O2 activation and fast electron/proton transfer via interfacial synergy. In contrast, thick CuOx clusters (CPCu‐10) promote a surface‐adsorption‐controlled pathway with intermediate accumulation, highlighting a mechanism switch from interfacial activation to ...

Interfacial Proton‐Relay Microenvironment Enables Self‐Driven Singlet Oxygen Generation under Neutral Conditions

Advanced Science, EarlyView.
An interfacial proton‐relay microenvironment at MoS2‐CuCl heterostructures enables selective O2 activation to 1O2 under neutral conditions. Electron‐deficient sulfur sites mediate proton transfer to Cu‐bound O2, accelerating *OOH hydrogenation while suppressing O─O bond cleavage, achieving stable, efficient pollutant removal.

Standardless LA-ICP-MS fission-track dating in apatite: comparison with uranium thin film and LA-ICP-MS ζ-calibration

Abstract Over the past two decades, the fission-track community has sought to calibrate the ages with LA-ICP-MS. This technique has not only made thermochronology faster but also enabled the determination of U-Pb ages and the measurements of trace elements which support geological interpretation.
