Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

Advanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...

A Universal and Versatile Zwitterionic Coating for Blood‐Contacting Catheters with Long Lengths and Complex Geometries

Advanced Science, EarlyView.
A universal and versatile zwitterion coating strategy is developed for blood‐contacting catheters with long lengths and complex geometries. The coating exhibits near‐zero fouling, superior anticoagulation, and selective biocapturing properties while maintaining excellent stability under dynamic blood flow.

Superelastic and Ultra‐Soft MXene/CNF Aerogel@PDMS‐Based Dual‐Modal Pressure Sensor for Complex Stimuli Monitoring

Advanced Science, EarlyView.
A triboelectric‐piezoresistive dual‐modal pressure sensor based on superelastic and ultrasoft MXene/cellulose nanofiber (CNF) aerogel@PDMS is fabricated. The sensor exhibits high sensitivity and stable sensing performance via a dual mechanism. Through the effective combination of these two mechanisms, comprehensive monitoring of complex stimuli can be ...
