ZnO nanoparticles have been prepared by a simple method in a short period of time. In this synthetic method, the sample was obtained using Zn(CH3COO)2·2H2O and a new template of hexamine salt. Their crystalline structure and morphology were studied by XRD and SEM. The optical properties of the sample were studied by UV–visible spectroscopy. The absorption spectr...

This study was conducted to evaluate the effect of different concentrations of selenium and zinc nanoparticles on growth performance, survival and chemical composition of Whiteleg shrimp (Litopenaeus vannamei). For this purpose, shrimp with an average weight of 5.1±0.2 g were distributed in 12 fiberglass tanks with 25 shrimp density and were fed for 56 days with different concentrations of sele...

 The soft chemical method was adopted to prepare of cobalt-substituted nickel-zinc ferrites (Ni0.95-x Zn0.05COx Fe2O4 for x = 0.01, 0.02 and 0.03). We have recently studied their structural, morphological, magnetic properties, initial permeability, dielectric constant. They were found be with cubic ferromagnetic spinel structure, the morphology which is suitable high-density recording med...
