Realization of complex curved waveguide based on local resonant 3D metamaterial
To overcome the negative impact of diffraction effect on the transmission wave front at the bend and to improve the transmission efficiency of acoustic wave in the bend waveguide, the finite element method by COMSOL was used to simulate the propagation ...

Hybrid Liquid Metal Cathode Enables High‐Performance Intrinsically Stretchable OLEDs
We report a hybrid liquid metal (Hyb‐LM) cathode engineered via selective rupture of liquid metal particles (LMPs), forming a bilayer architecture with a surface liquid metal (LM) layer and underlying LMP layer, which has benefits of both LM and LMPs.

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Solid-driven mechanism and experimental study based on surface acoustic wave microfluidic
This study proposes a method to drive a solid by liquid–solid coupling and designs and manufactures a surface acoustic wave actuator to drive a wetted solid ball. The solid ball moves under surface acoustic wave microfluidic acoustic streaming.

Ductility Tuning via Cluster Network Characteristics of Porous Components
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by
