Vortical structure in the wake of a transverse jet [PDF]

, 1994
Structural features resulting from the interaction of a turbulent jet issuing transversely into a uniform stream are described with the help of flow visualization and hot-wire anemometry. Jet-to-crossflow velocity ratios from 2 to 10 were investigated at

Thickness Dependence of Linear and Nonlinear Optical Properties of Multilayer 3R‐MoS2

Advanced Optical Materials, EarlyView.
Thickness as a key design parameter for optimizing the nonlinear optical response of layered transition metal dichalcogenides (TMDs) materials is established. The demonstrated correlation between thickness, linear spectra, and harmonic generation efficiency provides a powerful framework for tailoring nonlinear performance.

Computation‐Guided Dual‐Site Electrocatalysts for Record‐Performance Nitrite‐to‐Ammonia Conversion

Advanced Science, EarlyView.
Designing Cu doped ZnO catalysts for NO2RR via first principles calculation and boosting electrocatalytic nitrite reduction through Cu‐ZnO synergistic deoxygenation, hydrogenation, and NH3 desorption. Cu doping elevates the d‐band center of Zn, strengthening *NO2 binding and deoxygenation, while ZnO sites regulate water adsorption and dissociation ...

Tailoring Intermediate Adsorption Through d‐band Mismatch Strategy of Heterojunction to Achieve Industrial Overall Water Splitting

Advanced Science, EarlyView.
This paper demonstrates the fabrication of a Ni3Mo/Ni3N junction to investigate d‐band engineering and elucidate the specific roles of Ni3Mo and Ni3N active sites in improving catalytic activity. Through integrated spectroscopic characterization and first‐principles modeling, for the first time, a d‐band mismatch mechanism has been proposed to ...

Intramolecular Synergy of CO2 Activation and H Spillover on Heteronuclear Dual‐Metal Phthalocyanine Assemblies for Selective CO2 Photoreduction

Advanced Science, EarlyView.
The CuNiPc/BiVO4 heterojunction is designed and synthesized for selective CO2 photoreduction. The cascade interfacial Z‐scheme charge transfer and the intramolecular synergy of Cu–Ni dual sites on CO2 activation and H spillover contribute to the high photocatalytic performance and selectivity. ABSTRACT Solar‐driven CO2 conversion holds great promise in
