Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

Angewandte Chemie, EarlyView.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.

Nanostructured Deep Eutectic Systems in Healthcare: From Bioactive Solvents to Intelligent Biointerfaces, Wearables, and AI‐Driven Design

Advanced NanoBiomed Research, EarlyView.
Beyond the green solvent paradigm, this review redefines Deep Eutectic Systems (DES) as programmable supramolecular nanoassemblies. We survey their biomedical convergence: stabilizing thermolabile mRNA to enable cold chain‐free logistics, reshaping transdermal microneedle delivery, enabling long‐term wearables via eutectogels, and utilizing Generative ...

Carbon‐Confined Fe3C/Fe3N Janus Interfaces for Selective Nitric Oxide‐to‐Ammonia Electroreduction

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A defect‐rich, graphitic‐carbon‐confined Fe3C/Fe3N Janus catalyst integrates NO transport, adsorption/activation, and interfacial H supply for efficient nitric oxide electroreduction to ammonia. Built from earth‐abundant elements, this architecture enables high‐yield and high‐efficiency NH3 synthesis while valorizing industrial NO emissions.
