Entangled Multistable Origami with Reprogrammable Stiffness Amplification and Damping
Advanced Functional Materials, EarlyView.This study introduces a class of origami‐inspired metamaterials that overcome the limitations of existing multistable metamaterials by eliminating the need for rigid lateral confinements. Panel entanglement, snap‐through interactions, and instabilities synergy enable them to achieve extensive shape‐shifting, enhanced stiffness, and remarkable energy ...

Advanced Functional Materials, EarlyView.The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
