Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity

open access: yesAdvanced Science, EarlyView.
This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Enhanced Broadband Acoustic Absorption in Commercial Foam via Multiwall Carbon Nanotube‐Induced Pore Reconstruction

open access: yesAdvanced Science, EarlyView.
A simple to multiscale structure transition happens when a commercial porous foam is filled with multiwall carbon nanotubes with high aspect ratio. For an acoustic absorber with a porous material, the loading of multiwall carbon nanotubes can significantly improve its specific surface area while preserving its thickness and high porosity, thus enables ...
