Wonders of Harbor and Grey Seal Whiskers: Morphology, Natural Frequencies, and 3D Modeling

open access: yesAdvanced Science, EarlyView.
Seals detect prey by sensing vortices using whiskers. How whisker morphologies and locations respond to hydrodynamic signals across various frequencies remains unclear. This study measures whiskers’ natural frequencies and morphologies and maps them to whisker locations on the muzzle, providing insights into how seals interpret hydrodynamic signals ...

Superior Sodium Metal Anodes Enabled by 3D Hierarchical Metallic Scaffolds with Enhanced Sodiophilicity

open access: yesAdvanced Science, EarlyView.
This work develops a 3D conductive scaffold consisting of vertical crystalline TiO2 nanotube arrays embedded with ultrafine silver nanoparticles (denoted as Ag@TiO2 NTAs) with an ultrasonication‐assisted in situ deposition method for high‐performance Na metal batteries.

Reinforcing Stromal Cell Spheroid Through Red‐Light Preconditioning for Advanced Vascularization

open access: yesAdvanced Science, EarlyView.
This study presents a novel approach to enhance stromal cell therapy for myocardial infarction by combining OLED‐based photobiomodulation (OPBM) preconditioning with 3D spheroid culture of hADSCs. The engineered spheroids improve angiogenesis, arterialization, and cardiac function in vivo, offering a next‐generation therapeutic strategy to overcome ...

Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

open access: yesAdvanced Science, EarlyView.
Due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since the meta‐hologram is difficult to be refreshed, zoom meta‐holography has not been reported to date. This study proposes a multi‐wavelength achromatic 3D meta‐holography with a zoom function, breaking through both the chromatic ...
