Surface‐Exposed Pd Nanocluster Confined within a Ring‐Shaped Polyoxometalate for Selective Hydrogenation

open access: yesAdvanced Science, EarlyView.
A small Pd nanocluster is successfully prepared within a ring‐shaped polyoxometalate via a mild solid‐state reduction process. The resulting surface‐exposed Pd nanocluster functions as a robust heterogeneous reusable catalyst, enabling highly chemoselective hydrogenation of substrates containing multiple reducible functional groups via selective ...

Large‐Sized Poly (Triazine Imide) Crystals with Minimized Defects for High‐Efficiency Overall Water Splitting

open access: yesAdvanced Science, EarlyView.
Large‐sized PTI single crystals with significantly reduced defects and an extended π‐conjugated network are successfully constructed by using melon as a precursor. The optimized PTI achieves a high apparent quantum efficiency of 13.1% @365 nm for overall water splitting. This work highlights the critical role of precursor architectural compatibility in

Synergy between Defects and Lattice Distortion Drives Self‐Powered Elastico‐Near‐Infrared Mechanoluminescence in Cr3+‐Doped Spinel Oxides

open access: yesAdvanced Science, EarlyView.
This work demonstrates crystal lattice tailoring and defect modulation to engineer a Cr3+‐activated cubic spinel oxide, where strategic introduction of Cr3+ into octahedral Al3+/Li+ sites drives efficient NIR‐ML through a non‐trap‐based mechanism. Abstract Elastico‐mechanoluminescence (ML) enables unique force‐to‐light transduction for applications in ...

Accelerated Development of Vapor Deposition Technology for Efficient Perovskite Solar Cells via Accurate and Practical Machine Learning Tools

open access: yesAdvanced Science, EarlyView.
Based on rational feature selection, an integrated‐feature dataset is constructed encompassing macro‐ and micro‐feature parameters. Screening and optimization across ten algorithmic models enhanced predictive accuracy and robustness for power conversion efficiency (PCE), yielding an R2 of 0.9464 and RMSE of 1.27%.
