Electrically Tunable Graphene‐Metal Hybrid Metasurfaces for High‐Efficiency, Broadband Mid‐Infrared Transmission Modulation

open access: yesAdvanced Science, EarlyView.
A graphene‐metal hybrid transmissive metasurface enables electrically tunable mid‐infrared transmission modulation through ionic gel top gating. By combining graphene with a metallic slit metasurface, high modulation efficiency and broadband operation are achieved simultaneously, demonstrating efficient electrical control of mid‐infrared transmission ...

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

open access: yesAdvanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

open access: yesAdvanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Crystallized Domain Walls in HfO2 Enable Chessboard‐Type Ultra‐High‐Dense Ferroelectric Memory

open access: yesAdvanced Science, EarlyView.
In general, DWs in ferroelectrics stabilize within a widely spread transition region between two oppositely polarized domains, which severely limits the achievable memory density. Here, the reported DWs in HfO2 constitute perfect crystalline structures along arbitrary crystallographic directions, enabling the formation of the narrowest square‐shaped ...

Mechanophore‐Based Multichannel Colorimetric Force Sensors: Ultrasound‐Driven Stress and Strain Quantification

open access: yesAdvanced Science, EarlyView.
ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
