Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

Journal of Polymer Science, EarlyView.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

A Folding Magnetic Soft Sheet Robot With Real‐Time Reconfigurable Magnetization for Targeted Drug Delivery

SmartBot, EarlyView.
Magnetic robots have the characteristics of small size, non‐cable drive and motion agility, but multi‐angle folding and real‐time reconfigurable magnetization are difficult to be integrated into small‐sized soft structures. Here, the authors propose a magnetic soft sheet robot based on the dynamic magnetization characteristics of magnetorheological ...
