Broadband Conductance Matching Effect in Conductive Metamirrors

open access: yesAdvanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Metalens‐Enabled Twisted Chromatic Dispersion

open access: yesAdvanced Physics Research, EarlyView.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles

open access: yesBMEMat, EarlyView.
Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

Coupling of 0D/1D Grain Boundaries Inducing Extreme Charge Rearrangement/Magnetic Resonance for Ultrabroadband Electromagnetic Wave Absorption

open access: yesCarbon Energy, EarlyView.
The 0D/1D grain boundary coupling between Fe₃O₄ quantum dots and CNTs induces extreme charge redistribution and short‐range magnetic resonance, enabling complete electromagnetic wave absorption across the entire X and Ku bands. ABSTRACT Ferrite–carbon composites effectively absorb electromagnetic (EM) waves via coupled mechanisms.

Unveiling S‐Scheme Bi2WO6@Black‐TiO2 Heterostructure for Superior Photoelectrocatalytic Water Remediation

open access: yesCleanMat, EarlyView.
Bi2WO6@Black‐TiO2 hierarchical heterogeneous architectures are prepared via a simple hydrothermal/solvothermal strategy. An S‐Scheme carrier transfer mechanism with a solid ability to induce long‐lived electrons and holes with strong redox properties was identified via in situ x‐ray photoelectron spectroscopy and time‐resolved photoluminescence ...
