Niδ+ Atoms Anchored In Situ on Ultrathin Ni‐Phyllosilicate Nanosheet Ensure High‐Efficient CO2 Reduction into CO at Moderate‐Low Temperature

Advanced Science, EarlyView.
A novel supported Ni‐based catalyst, consisting of abundant Niδ+ atoms with low electron density anchored in situ on ultrathin Ni‐phyllosilicate nanosheet (a‐Niδ+−PSNS, 0< δ ≤1), achieve simultaneous outstanding CO2 conversion and CO selectivity. Their ultrathin nanosheet enables abundant anchored Niδ+ atoms to fully expose and disperse, which can ...

Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

Advanced Science, EarlyView.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

Visualizing Strain‐Coupled Cryogenic Phase Transitions and Defect Dynamics in Perovskite Quantum Dots Using In Situ STEM

Advanced Science, EarlyView.
Cryogenic cooling induces an orthorhombic‐to‐monoclinic phase transition in CsPbBr3 quantum dots, accompanied by pronounced strain localization at surfaces and interfaces. Multimodal in situ STEM directly visualize reversible defect healing during moderate cryogenic treatment and irreversible degradation upon prolonged exposure, revealing the intrinsic

NIR Ratiometric Fluorescent Antibody‐Drug Conjugate for Metastatic Ovarian Cancer Theranostics and Treatment Response Monitoring

Advanced Science, EarlyView.
In vivo optical imaging enhances antibody‐drug conjugate (ADC) optimization by enabling real‐time monitoring of stimulus‐responsive drug behavior. We report n501‐CYMMAF, a ratiometric theranostic with strong target affinity and low‐dose efficacy for ovarian metastasis.

Ultrafast Nonlinear Dynamics of Indium Tin Oxide Nanocrystals Probed via Fieldoscopy

Advanced Science, EarlyView.
The ultrafast nonlinear dynamics of indium tin oxide nanocrystals excited with 1 MHz, 10 fs pulses, at their localized surface plasmon frequency, and near their epsilon‐near‐zero wavelength is probed via fieldoscopy. The study demonstrates fluence‐dependent switching behavior, advancing the understanding of high‐speed optical modulation in plasmonic ...
