Dual‐Chamber One‐Step Molding Actuator with Straight‐Curved Crease Prismatic Design for Large‐Range Motions and Structural Stability

open access: yesAdvanced Science, EarlyView.
A dual‐chamber origami prismatic actuator is designed by integrating straight‐curved creases with folded partitions, enabling large‐range, multidirectional motions and enhanced structural stability. The actuator exhibits anisotropic stiffness and multiple actuation modes, and is fabricated via single‐material, one‐step molding.

Optically Driven Formation of Tailored Phonon Cavities

open access: yesAdvanced Science, EarlyView.
It is demonstrated that a structured optical field creates nanoscale “phonon cavities” in van der Waals materials, where atomic vibrations are confined and controlled in space and time. This approach enables programmable control of cavity geometry, symmetry, and frequency, and provides a platform for ultrafast studies of nonequilibrium interactions and
