Quantum Dots and Perovskites‐Based Physically Unclonable Functions for Binary and Ternary Keys via Optical‐to‐Electrical Conversion

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates optoelectronic PUFs that improve on traditional optical and electrical PUFs. The absorber materials are randomly coated through spray coating, ligand exchange, and dynamic spin coating. Incident light generates wavelength‐dependent binary multikey and enhances security ternary keys, approaching near‐ideal inter‐ and intra ...

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Unraveling Mixed‐Defect Transformations and Passivation Dynamics in Silicon Heterojunction Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Defects in materials coexist in multiple forms, undergo dynamic transformations, and influence the material properties. Here, the dynamic transformations of passivation‐related defects in silicon heterojunctions are revealed through the decomposition of dual‐phase capacitance transients.
