Self‐Oscillating Helix Showing Amplified Winding and Unwinding Motions

Advanced Materials, EarlyView.
The hydrogel helix exhibits autonomous oscillation synchronized with the Ru(bpy)32+/3+ redox cycle in the Belousov–Zhabotinsky reaction. Periodic winding–unwinding accompanies magnified motion along one direction within the gel phase. ABSTRACT Helical architectures in nature amplify motion via winding–unwinding.

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

Advanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

Advanced Materials, EarlyView.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

High‐Density Topological Defect Array by Two‐Step Interference Photoalignment

Advanced Materials, EarlyView.
High density arrays of topological defects in nematic liquid crystal are realized by two‐step interference photoalignment, with a minimal distance of 1.25 micrometer and disclination lines connecting defects on opposing substrates. Such layers can be used as reconfigurable templates for photonic devices to achieve large angle diffraction, beam shaping ...
