Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

Advanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

Advanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,
