Spatially Separated Molecular Activation Over Dual Sites in Sn‐Doped ZnGa2O4/SnO2 Photocatalysts Toward Complete VOCs Mineralization

open access: yesAdvanced Science, EarlyView.
The graphical abstract illustrates the photocatalytic mechanism of Sn‐doped ZnGa2O4 with in situ loaded SnO2 (SZGO), highlighting directional electron migration and selective adsorption/activation. ZnGa2O4 domains facilitate H2O activation to generate ·OH radicals, while SnO2 domains enriched with electrons promote O2 activation to form ·O2− and 1O2 ...

Tunable Ni‐Based Alloys as Electrons Donor in Dielectric Isolated Islands to Achieve Broad Frequency Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Tunable electronic sources using Ni‐based alloy in Nitrogen ‐ doped carbon (NC) microdomain are designed to balance the skin effect and the dielectric loss ability. These Ni‐based alloy NPs in dielectric isolated islands can serve as electronic sources to provide abundant mobile electrons to NC nanolayers, thus improving dielectric loss capability 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%.
