Cascade‐Responsive MXene@Cu‐MOF Heterostructure Integrates Antioxidant Activity, Infection Control, and Vascularization for Tracheal Repair

Advanced Science, EarlyView.
A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Vertically Aligned Ion Pathways for Fast Conduction and Uniform Lithium Deposition in Solid‐State Batteries

Carbon Energy, EarlyView.
Under an alternating electric field, the lithiated halloysite nanotubes (HNTs–SO₃Li) self‐assemble into a perpendicular orientation, creating continuous pathways with low tortuosity that markedly enhance room‐temperature ionic conductivity. The shortened diffusion path within this alignment enables rapid Li⁺ transport, while the establishment of a ...
