Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

open access: yesAdvanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...

Wireless Acousto‐Piezoelectric Conduit with Aligned Nanofibers for Neural Regeneration

open access: yesAdvanced Materials, EarlyView.
An ultrasound‐driven, highly aligned piezoelectric nanofiber‐based nerve guidance conduit (APNF‐NGC) designed for effective peripheral nerve repair has been demonstrated in this study. Featuring aligned topology, cell‐adhesive surfaces, and an axial electric field, the APNF‐NGC collectively promotes significant nerve regeneration.

Skeletal High‐Strength Nanoporous Copper and Metamaterials: The Hakka Tulou Design Heritage

open access: yesAdvanced Materials, EarlyView.
Inspired by the Hakka Tulou walls, skeletal nanoporous copper is fabricated via a two‐phase MnCu precursor and controlled dealloying. This strategy achieves high strength (200 MPa) and large specific surface area (27.6 m2/g), and extends to lattice metamaterials with hierarchical porosity, offering new design pathways for multifunctional metal ...

Programmable Continuous Electrowetting of Liquid Metal for Reconfigurable Electronics

open access: yesAdvanced Materials, EarlyView.
This work introduces a programmable continuous electrowetting (CEW) approach for the dynamic manipulation of liquid metal (LM), enabling directional control via electrochemical modulation. By leveraging laser‐induced graphene (LIG) substrates, a wide range of utilities is demonstrated, including fluidic “valves,” logic gates, and reconfigurable ...
