Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

Advanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Chiral Nanohoops as an Efficient Spin Polarization System

Advanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...
