In this study, multilayer perception neural network (MLPNN) was employed to predict thermal conductivity of PVP electrospun nanocomposite fibers with multiwalled carbon nanotubes (MWCNTs) and Nickel Zinc ferrites [(Ni0.6Zn0.4) Fe2O4]. This is the second attempt on the application of MLPNN with prey predator algorithm for the prediction of thermal conductivity of PVP electrospun nanocomposite fi...

For the manufacture of high permeability Mn-Zn ferrite cores, the zinc loss from the surface of sintering cores causes poor yield rate of final products. This experiment uses the atmospherical protection to reduce the evaporation of zinc. The control of the oxygen partial pressure and flow rate precisely can reduce the zinc loss about 20% to 35%, but it is not enough to get a good distribution ...

Crystalline and nanostructured cobalt (CoFe2O4), nickel (NiFe2O4), zinc (ZnFe2O4) and manganese (MnFe2O4) spinel ferrites are synthesized with high yields, crystallinity and purity through an easy, quick, reproducible and low‐temperature hydrothermal assisted route starting from an aqueous suspension of coprecipitated metal oxalates. The use of water as a reaction medium is a further adva...

The aim of this study was to the structure, morphology, magnetic, and magnetorheological properties cobalt cobalt-zinc ferrite powders be used as a functional component fluids. Ferrites CoFe2O4 Co0.65Zn0.35Fe2O4 were obtained by combined hydrolysis inorganic metal salt in aqueous solutions followed thermal treatment precipitates. ferrites studied means X-ray phase analysis, scanning electron mi...

in order to examine the effects of silver, zinc, nickel, zinc- copper nanoparticles on germination, seedling establishment, and enzyme activity of alfalfa seeds, a factorial experimental was conducted in a randomized complete design with three replications in the seed laboratory, college of agriculture and natural resources, university of tehran in karaj. the objective of this study was to dete...

Ultra-violet protection and self-cleaning action of nano zinc oxide (ZnO) and titanium di-oxide (TiO2) with acrylic binder has been assessed on the cotton fabric using pad-dry-cure method. Different precursors, such as zinc acetate and titanium tetrachloride have been used to synthesize nanoparticles. Zinc acetate is synthesized into nanoparticle by wet chemical technique and titanium tetrachlo...

Background and Objective: Nanoparticles have been introduced as novel antimicrobial agents because of their properties that are different from their bulk properties. Present study was aimed to investigate antimicrobial activity of silver nitrate and zinc oxide nanoparticles against three main bacteria responsible for nosocomial infections, S. aureus, P. aeruginosa and A. baumannii. Materials a...

Abstract Ferrite nanoparticles are magnetic. They also show photocatalytic and antibacterial activities. These unique properties make them extremely useful for various applications e.g., they can potentially be used electronic equipment, telecommunication systems, radar, sensing material, catalytic applications, several biomedical applications. Several methods have been developed to synthesise ...

in this research zinc oxide (zno) nano-crystalline powders were prepared by sol-gel method using zinc acetate. the zno nanoparticles were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), ultraviolet-visible (uv-vis), fourier transform infra-red (ft-ir) and energy dispersive x-ray (edx) spectroscopy. the structure of nanoparticles was studied using xrd pattern. the c...
