unsubstituted phthalocyanines of co, fe and mn supported on zinc oxide nanoparticles were prepared and were well characterized with x-ray diffraction (xrd) and scanning electron microscopy (sem). the oxidation of alcohols with tert-butylhydroperoxide (tbhp), in the presence of metallophthalocyanines (mpc) supported on zinc oxide nanoparticles was investigated. these mpc/zno nanocomposites were ...
A novel nanopackaging film was synthesized by incorporating ZnO nanoparticles into a poly-lactic acid (PLA) matrix, and its effect on the quality of fresh-cut apple during the period of preservation was investigated at 4 ± 1 °C for 14 days. Six wt % cinnamaldehyde was added into the nano-blend film. Scanning electron microscope (SEM) analysis showed a rougher cross-section of the nano-blend fil...
In this work, several nano/microscale structures of ZnO including nanospindles, microbundles, microrods, and nanoflowers have been prepared via a facile template and surfactant-free hydrothermal method mediated with ammonium molybdate. It is found that the morphology of ZnO could be readily tailored by simple variation of the concentration of ammonium molybdate. The effects of the concentration...
Zinc oxide [ZnO] thin films are deposited using a radiofrequency magnetron sputtering method under room temperature. Its crystalline quality, surface morphology, and composition purity are characterized by X-ray diffraction [XRD], atomic force microscopy [AFM], field-emission scanning electron microscopy [FE-SEM], and energy-dispersive X-ray spectroscopy [EDS]. XRD pattern of the ZnO thin film ...
Pure ZnO and Sr doped ZnO nanoparticles are synthesized via Co-precipitation method using Zinc acetate dehydrate Zn (CH3COO)2. 2H2O, Strontium acetate Sr (CH3COO)2, as source materials. The influence of Sr dopants contents on the morphology, absorption, emission, and photocatalytic activity of ZnO synthesized nanoparticles was investigated systematically. The photocatalytic activity of pure and...
The degradation of methyl tert-butyl ether (MTBE) was investigated in the aqueous solution of coated ZnO onto magnetite nanoparticale based on an advanced photocatalytic oxidation process. The photocatalysts were synthesized by coating of ZnO onto magnetite using precipitation method. The sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibration samp...
ruthenium dioxide nanoparticles (ruo2 ) with an average particle size of 50 nm are readily synthesized from rucl3.xh2o via the precipitation process in the presence of in-situ sodium octanoate as anionic surfactant. the phase composition, morphology, lattice parameters and size of nanoparticles in these products are characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffrac...
The present study aims at study on combined effect of zinc oxide nanoparticles (ZnO) with common agricultural fungicides. Nanoparticles were synthesized using chemical reduction process and characterized by UV-Visible spectroscopy, X-ray diffraction (XRD), Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM). Synthesized nanoparticles were observed to be in size range of 12...
Nano particles have received increased attention regarding their potential utility in biomedicine. In this study, we have investigated the antibacterial activity of ZnO nano particles with various particle sizes. ZnO nano particles were synthesized by conventional precipitation method using zinc sulphate and sodium hydroxide as precursors followed by the calcinations of precipitates at 350 °C f...
Objective: In this study we would like to report the synthesis of pure and group I element doping of ZnO nanoparticles (ZnO-NPs) prepared using gelatin. The use of natural polymers for the preparation of the pure and doped nanoparticles can result in achieving low cost and eco-friendly advantages.Materials and Method: Pure and doped ZnO-NPs were obtained at 500 °C and The cytotoxicity of nanopa...
