Advanced Science, EarlyView.Self‐healing separators are developed by grafting ureidopyrimidinone (UPy) quadruple hydrogen‐bonding motifs onto PE‐HEMA copolymers, blended with high‐MW PEO via solvent‐free hot‐pressing. The dynamic UPy network enables autonomous healing, restoring functionality after short circuits.

A Novel MCR of Isocyanates, Aldehydes, and Dienophiles
, 2016 A novel one-pot procedure for the three-component coupling reaction of isocyanates, aldehydes, and dienophiles (IAD reaction) has been developed. Condensation of isocyanates and aldehydes and subsequent Diels−Alder reactions with electron-deficient ...

Advanced Science, EarlyView.Tools for controlled selenol delivery are crucial for exploring Se‐related biology and medicine, but compound platforms for triggerable release of CH3SeH remain lacking. Herein, we report the first general triggered platform (TD‐MSe) for efficient cyclization release of CH3SeH in live cells.

Advanced Science, EarlyView.A bio‑based thermoresponsive controlled‑release fertilizer (TRBF) is fabricated by introducing F127 into a castor‑oil‑derived polyurethane coating. Distinct from conventional bio‑based coated fertilizer (BCF), TRBF achieves temperature‑regulated nitrogen release via F127 reversible phase transition, suppressing nutrient leakage at low temperature and ...
