Computation‐Less, Bias‐Free, and Ultra‐Broadband Photodetector for On‐Chip Edge Extraction

open access: yesAdvanced Materials, EarlyView.
A computation‐less, bias‐free, and ultra‐broadband photodetector directly converts local optical‐intensity gradients into signed photocurrents through a position‐dependent bi‐directional photoresponse. This intrinsic physical sensing mechanism enables single‐pixel edge extraction from the near‐infrared to the long‐wave infrared at room temperature ...

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

open access: yesAdvanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.

A Multifunctional Ionograsper Enabling Ion‐Redistribution Proximity Sensing and Structural‐Reconfiguration‐Driven Bidirectional Actuation

open access: yesAdvanced Materials, EarlyView.
A solid‐state ionic actuator integrates sensing, actuation, and memory within one material. A brief UV pulse induces long‐lasting deformation via coupled network rearrangement, dehydration, and rehydration, while ionic redistribution enables self‐powered sensing, supporting multifunctional, energy‐efficient soft robotic functions without continuous ...

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

open access: yesAdvanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.
