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 ...

Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.

Edge‐Delocalized Electron Effect on Self‐Expediating Desolvation Kinetics for Low‐Temperature Li─S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The self‐transformed Schottky heterojunction on MXene is developed to facilitate the dissociation of Li (solvent)x+ to achieve fast Li+ desolvation to promote rapid sulfur conversion kinetics by decreasing the related barriers, contributing to high‐performance Li─S batteries under low‐temperatures.

Pericyte‐Assisted Vascular Lumen Organization in a Novel Dynamic Human Blood‐Brain Barrier‐on‐Chip Model

open access: yesAdvanced Healthcare Materials, EarlyView.
Organ‐on‐Chip (OoC) technology enables the precise modeling of the blood‐brain barrier (BBB). This study presents a microfluidic device that mimics brain microvessels, integrating co‐culture with pericytes and astrocytes under pulsatile flow. Results show that perivascular cells modulate endothelial morphology, promoting lumen formation and barrier ...
