Synergistic Ni Single Atoms/Nanoparticles on CeO2 for High‐Performance and Durable SOFC Hydrogen Electrodes

open access: yesAdvanced Science, EarlyView.
Combination of UiO‐66(Ce) metal organic framework‐templated synthesis and in‐situ exsolution creates porous CeO2‐based anode decorated with Ni single atoms/nanoparticles, synergy of which leads to enhanced electronic/ionic transport, accelerated H2 oxidation, improved stability, and finally outstanding peak power density among oxide‐based SOFC anodes ...

Thermally Driven Supramolecular Chirality Evolution in Low‐Bandgap Fused‐Ring Conjugated Molecules for High‐Performance NIR Circularly Polarized Light Detection

open access: yesAdvanced Science, EarlyView.
A supramolecular chirality evolution strategy in chiral low‐bandgap fused‐ring conjugated molecules enables high‐performance near‐infrared (NIR) circularly polarized light photodetection. Halogen substitution and thermal annealing induce chiral amplification and hierarchical ordering. Integrated into Schottky barrier vertical transistors, the optimized

Halide Perovskite: A Rich Source of Thermal Insulator

open access: yesAdvanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Efficient Hot Carrier Management in Lead Halide Perovskite Micro‐Disks Revealed by Super‐Diffusive Migration

open access: yesAdvanced Science, EarlyView.
Hot‐carrier transport in metal halide perovskites is investigated using spatiotemporally‐resolved photoluminescence microscopy. Mesa‐shaped MAPbBr3 microdisks exhibit anomalous super‐diffusive carrier propagation on nanosecond timescales, driven by hot‐carrier stabilization and strong carrier–phonon coupling.
