Synergistic Sunlight‐Activated Photodynamic and Near‐Infrared‐Induced Mild Photothermal Therapy for Infected Wound Healing Using Functionalized Nano‐Bi2WO6 Composites

Advanced Science, EarlyView.
This work proposes a multifunctional Bi2WO6:Yb,Er@CuS@CS nanocomposite that integrates photodynamic therapy (PDT), near‐infrared‐triggered photothermal therapy (PTT), and Cu2+ release for infected wound repair. The nanocomposite demonstrates enhanced antibacterial efficacy via combined PDT, PTT, and Cu2+ release, effective immunomodulatory by mild ...

Role of Epoxide Functionalization of Amines for Development of Direct Air Capture Sorbents with High Cyclic Working Capacity at Low Desorption Temperatures

Advanced Science, EarlyView.
Appropriate butylene oxide (BO) functionalization of amines (polyethyleneimine (PEI1200 and PEI300) and tris(2‐aminoethyl)amine (TREN)) enables excellent cyclic working capacities (WCcyclic) at low desorption temperatures (40−70°C). Notably, 0.30BO‐PEI300‐SY and 0.54BO‐TREN‐SY show the highest WCcyclic at 45 and 40°C, respectively.
