Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

open access: yesAdvanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...

Phase Smoothing for Mutual Coupling Mitigation in Multifunctional Metasurfaces Designed with Diffractive Neural Networks

open access: yesAdvanced Optical Materials, EarlyView.
A diffractive neural networkdesigned metasurface operating at 86 GHz generates multiple holographic patterns by controlling the phase of subwavelength unit cells. A phase‐smoothing regularization mitigates mutual coupling, enabling accurate multifunctional wavefront shaping.

Metalens Array for Complex‐Valued Optical Discrete Fourier Transform

open access: yesAdvanced Optical Materials, EarlyView.
A single‐layer metalens‐array device performs complex‐to‐complex discrete Fourier transforms (DFTs) optically with O(N) digital time complexity. Integrated interferometric phase retrieval and error mitigation scheme enables accurate, compact, and low‐power optical computing. The approach provides a versatile framework for implementing arbitrary complex‐
