Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

open access: yesAdvanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

Boosting Sensory Nerve‐to‐Bone Interactions Enhances Hedgehog Mediated Calvarial Bone Repair

open access: yesAdvanced Science, EarlyView.
Boosting sensory nerve activity via TrkA agonism strongly accelerates calvarial bone repair in adult mice. Furthermore, single‐cell RNA sequencing and neuron–bone interactome analyses identify these sensory neurons as a direct neural source of Hedgehog pathway ligands. Consequently, these ligands drive osteoblast differentiation of skeletal progenitors,

Spatially Separated Redox Centers in One‐Dimensional Sp2‐Carbon Covalent Organic Frameworks Enable Synergistic Photocatalytic Palladium Recovery and Bisphenol A Mineralization

open access: yesAdvanced Science, EarlyView.
A one‐dimensional sp2‐carbon covalent organic framework with spatially segregated redox centers integrates a dual photosensitizing system and a cationic interface for synergistic photocatalysis. The material achieves exceptional palladium recovery (1749 mg g−1) and bisphenol A mineralization (0.1710 min−1) without sacrificial agents, demonstrating ...

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

open access: yesAdvanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.
