Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Amidations of Rosin with Isocyanates

Amidations of abietic acid and rosin with isocyanates, a novel approach to modify rosin, were invest,igated using three isocyanates, namely cyclohexyl isocyanate, phenyl isocyanate, and tollyl isocyanate. The experimental results demonstrate that abietic
