Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature

Advanced Science, EarlyView.
Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...

Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

Bio‐Propelled Stomatocyte Nanomotors with Glutathione‐Responsiveness for Osteoarthritis Treatment

Angewandte Chemie, EarlyView.
Glutathione (GSH)‐responsive stomatocyte nanomotors with encapsulated MTX utilize oxygen to achieve autonomous motion and undergo GSH‐induced dissociation, enhancing cellular uptake, tissue penetration, and MTX release within the osteoarthritis (OA) region, thereby improving therapeutic efficacy.
