Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

In Situ Bioorthogonal Synthesis of PROTACs via Dual‐Responsive Cleavage for Synergistic Photo‐Immunotherapy

Advanced Science, EarlyView.
A bioactive self‐delivering SNAP‐TAC platform responds to tumor‐associated cathepsin B and glutathione, enabling in situ bioorthogonal synthesis of a BRD4‐degrading proteolysis‐targeting chimera within the tumor microenvironment. The resulting BRD4 degradation and PD‐L1 downregulation synergize with photodynamic therapy‐induced immunogenic cell death ...

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.
