Precision‐Engineered Silver Single‐Atom Carbon Dot Nanozymes for Theranostic Management of Acute Kidney Injury

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, Volume 16, Issue 9, 4 March 2026.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Overdischarge of Spent Lithium Ion Batteries Induced Copper Deposition Onto Cathode for Better Upcycling

Battery Energy, Volume 5, Issue 2, March 2026.
Deep discharging spent lithium‐ion batteries drives copper migration from the anode to the cathode, where it forms beneficial doping and surface coatings during the upcycling process that enhance the performance of regenerated cathode materials. ABSTRACT An efficient recycling strategy is of importance for reducing the environmental impact of spent ...
