Achieving High‐Performance Transcranial Ultrasound Transmission Through Mie and Fano Resonance in Flexible Metamaterials

Advanced Science, EarlyView.
Transcranial ultrasound holds great potential in medical applications. However, effective transcranial ultrasound transmission remains challenging. To address these, this work introduces an innovative Mie‐resonance flexible metamaterial (MRFM), which consists of periodically arranged low‐speed micropillars embedded within a high‐speed flexible ...

Selective Sorting of Semiconducting C70@Single‐Walled Carbon Nanotube Heterostructures with Narrow Diameter Distribution

Advanced Science, EarlyView.
A precise synthesis of C70 fullerene‐filled SWCNTs (C70@SWCNTs) is achieved through vapor‐phase filling followed by polymer sorting. As the SWCNT diameter increases, C70 molecules first stack in a single chain, and then form unusual configurations, including staggered double chains and double helices.
