Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

Co‐Treatment With rhBMP‐2 and Rapamycin Modulates Osteogenesis–Adipogenesis Balance to Enhance Aged Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Pearl‐Like Bioinspired Coating Enables Regulation of Mg Degradation for Osteoporotic Bone Repair

open access: yesAdvanced Science, EarlyView.
In this study, inspired by pearl architecture, we developed a layered Ca–P “brick” and Fn‐mimetic peptide “mortar” coating on Mg alloys. The Ca–P layer moderates corrosion and offers mineral cues, while the peptide enhances adhesion and regulates immune‐vascular responses.

CGRP Enhances the Regeneration of Bone Defects by Regulating Bone Marrow Mesenchymal Stem Cells Through Promoting ANGPTL4 Secretion by Bone Blood Vessels

open access: yesAdvanced Science, EarlyView.
ABSTRACT Bone angiogenesis is important for bone formation and regeneration after bone injury. Endothelial‐derived angiogenic factors are key signal transducers in the bone microenvironment and maintain vascular–osteogenic coupling during bone regeneration.

Integrating Cooperative Dual Active Sites Onto a Plasmonic Photocatalyst for Synergistic Promotion of the Reduction and Oxidation Half‐Reactions in Ammonia Synthesis

open access: yesAdvanced Science, EarlyView.
An efficient N2 fixation photocatalyst, Ru‐WO3−x/CoOx, is prepared by integrating respective reduction and oxidation sites onto a plasmonic semiconductor. Owing to optimized reaction kinetics and promoted charge carrier separation by the synergistic effect between the two types of active sites, the involved reduction and oxidation half‐reactions are ...
