Trapped Fluorine Enables Thermally Stable Broadband Photodetection in Graphene/Fluorinated Graphene Heterostructure

Advanced Materials Technologies, EarlyView.
Fluorinated graphene has opened new opportunities for real‐world applications; however, its working and thermal stability are key issues for practical use. This study successfully demonstrates the stability of a fluorinated graphene‐based photodetector, achieved through a graphene, fluorinated graphene heterostructure (Gr/F‐Gr HS).

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

Advanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,
