This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Interference Pattern Caused by Bilateral Bone Conduction Stimulation Impairs Sound Localization
This work explores how crosstalk‐induced wave interference affects bone conduction (BC) sound localization. Using a theoretical model, cadaveric vibrometry, and psychoacoustic tests, atypical BC lateralization patterns are revealed that contradict air conduction (AC) principles.

Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...
