Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites

Advanced Materials, EarlyView.
Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

Advanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...
