Wireless Acousto‐Piezoelectric Conduit with Aligned Nanofibers for Neural Regeneration
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.

Standalone Integrated Magnonic Devices
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

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

The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...
