Bismuth Silicate Catalyst for Efficient Electrocatalytic CO2 Reduction and Electrolyte‐Free Formic Acid Production

open access: yesAdvanced Science, EarlyView.
Layered Bi2SiO5 is designed that electrochemically reconstructs into a highly active Bi@Bi2O2CO3 catalyst for CO2‐to‐formate conversion. The system operates efficiently over a wide operating range. Coupling with solid‐state electrolyte system enables continuous production of electrolyte‐free formic acid, simplifying separation and reducing energy ...

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

open access: yesAdvanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

Oral Exposure to Food‐Grade Nanoparticles Poses a Risk of Alzheimer's Disease‐Like Symptoms by Triggering Autophagy Defects in Neurons

open access: yesAdvanced Science, EarlyView.
Three food‐grade nanomaterials induce dysregulated RyR‐Ca2+ signaling through epigenetic modifications. This dysregulation impairs the autophagic clearance process, ultimately leading to abnormal Aβ deposition and increase phosphorylated tau levels.

Virulence‐Selective Trap–Capture–Kill Antibacterial Nanostructures With Immune–Metabolic Regulation for Treating Implant‐Associated Infections

open access: yesAdvanced Science, EarlyView.
A virulence‐selective antibacterial system based on fascaplysin derivative 14‐modified TiO2 nanostructure (F‐14‐TNA) is developed for treating implant‐associated infections. F‐14‐TNA selectively traps hyperpathogenic bacteria via chemotaxis, captures them electrostatically, and kills them via reactive oxygen species‐mediated pathways.
