RISSynergistic effect of low and high intensity ultrasonic irradiation on the direct growth of ZnO nanostructures on the galvanized steel surface: investigation of the corrosion behavior
has advantages compared to the pure Zn foil (used in other researches). In addition, in the present work, the effective pretreatment of the base substrate surface by applying the chemical etching under the low intensity ultrasonic irradiation...
Investigation of the uncommon basic properties of [Ln(W5O18)2]9– (Ln = La, Ce, Nd, Gd, Tb) by changing central lanthanoids in the syntheses of pyrazolopyranopyrimidines
of pyrazolopyranopyrimidines via a four-component reaction, involving ethyl acetoacetate, hydrazine hydrate, benzaldehydes, and barbituric acid under ultrasonic irradiation. The catalytic activity of these catalysts with different Ln were compared under the same optimized...
Photocatalytic Degradation and Mineralization of Reactive Textile Azo Dye Using Zinc Sulfide Nanoparticles Prepared by Ultrasound
successfully prepared under different conditions by choosing different ultrasonic irradiation time (0, 5, 30 min). The stability and reusability of the catalysts were examined. The results showed that the sample prepared by 30 min ultrasound irradiation can...
Photocatalytic degradation of reactive black 5 azo dye by zinc sulfide quantum dots prepared by a sonochemical method
Zinc sulfide (ZnS) nanoparticles (NPs) with an average particle size of 2 nm were
successfully synthesized under ultrasonic irradiation without any surfactant and high
temperature treatment. Prepared NPs were characterized by powder X...
Photostability and visible-light-driven photoactivity enhancement of hierarchical ZnS nanoparticles: The role of embedment of stable defect sites on the catalyst surface with the assistant of ultrasonic waves
Zinc sulfide is a UV-active photocatalyst and it undergoes photocorrosion under light irradiation.
In this work, the defect sites on ZnS nanoparticles (NPs) surfaces were induced with the help of powerful
ultra- ...
Graphene oxide nanosheets synthesized by ultrasound: Experiment versus MD simulation
to characterize the GO samples. According to XRD analysis, GO-U samples showed fewer layers than GO-C samples. The TG analysis indicated that the graphene oxide prepared with 20 min ultrasonic irradiation (GO-U20) has more oxygen-containing functional groups...
Effect of Ultrasonic Irradiation on the Properties and Performance of Biodiesel Produced from Date Seed Oil Used in the Diesel Engine
.9% yield and 91.9% ester). The ultrasonic irradiation also influenced on the physicochemical properties of DSO biodiesel and improved its combustion in the diesel engine. The analysis results related to the engine and gas emission confirmed...
A novel approach for the synthesis of superparamagnetic Mn3O4 nanocrystals by ultrasonic bath
. The chemical composition was obtained by EDS analysis and confirmed the presence of
Mn and O in the sample. According to the TEM and HRTEM results, both nanorods and nanoparticles of
Mn3O4 were obtained in the presence of ultrasonic irradiation...
