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 ...

VOx‐Based Non‐Volatile Radio‐Frequency Switches for Reconfigurable Filter

open access: yesAdvanced Science, EarlyView.
Vanadium oxide‐based memristor devices achieve high performance for next‐generation non‐volatile memory and RF switches. These devices demonstrate a cutoff frequency of ≈4.5 THz, low insertion loss (<0.46 dB), and high isolation (>20 dB) from 0.1 to 20 GHz with stable operation extended to 67 GHz.

Mercaptophenylboronic Acid‐Mediated Nanozyme Immunochromatographic Assay for Simultaneous Detection of Respiratory Bacteria and Virus

open access: yesAdvanced Science, EarlyView.
This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...

Highly Stretchable, Self‐Healable, and Conductive Gelatin Methacryloyl Hydrogel for Long‐Lasting Wearable Tactile Sensors

open access: yesAdvanced Science, EarlyView.
Gelatin methacryloyl hydrogel, which possesses high stretchability, tensile strength, toughness, and autonomous self‐healing capability at room temperature, is developed through the introduction of interpenetrating networks, hierarchical hydrogen bonds (weak and strong H‐bonds), and borate ester bonds.
