Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Advanced Functional Materials, EarlyView.A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.
