Magnetic nanocrystals with a narrow size distribution hold promise for many applications in different areas ranging from biomedicine to electronics and energy storage. Herein, the microwave-assisted sol-gel synthesis and thorough characterization of size-monodisperse zinc ferrite nanoparticles of spherical shape is reported. X-ray diffraction, 57Fe Mössbauer spectroscopy and X-ray photoelectron...

The CoFe2O4 nanoparticles have been synthesized by using a stable ferric salt of FeCl3 with a micellar microemulsion method. The normal micelles are formed by sodium dodecyl sulfate (NaDS) in aqueous solutions. The mean size of the nanoparticles can be controlled from less than 4 nm to about 10 nm through controlling the concentrations of the reagents. The neutron diffraction in combination wit...

Characterization of a tunable & switchable microstrip rectangular patch antenna printed on synthesized LiTi ferrite substrate with a normal magnetic bias field is presented. In this paper the concept of switching and tuning has been described by magnetostatic and spin waves phenomenon. The DC magnetic biasing generate these both type of waves which response a number of novel magnetic and electr...

This study was conducted to examine the synthesis of ZnFe2O4 nanoparticles, using the hydroethanolic extract of Citrus aurantium flowers, through the application of FeCl2.4H2O, FeCl3.6H2O, and Zinc Acetate. The present piece of work is regarded important especially when ascertaining the potential of a widely distributed underused mangrove associated plant, C. aurantium, as used in the folk medi...

Abstract Zinc substituted nickel ferrite (Zn x Ni 1 − Fe 2 O 4 ) is investigated under density functional theory (DFT) within the DFT + U approximation for ≤ 0.50, with particular interest in understanding effect of Zn on net magnetization. Using as a reference ZnFe , localization d band proved to have large impact preference occupy either tetrahedral A or octahedral B coordination sites, which...

Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis. In this work, the effect of nickel and magnesium on zinc electrodep...

The cobalt substituted Nickel-Zinc ferrites with the composition Ni0.95-xZn0.05CoxFe2O4, for x= 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 were synthesized by soft chemical route method found to have cubic system of ferrimagnetic spinel using XRD. grain sizes decreases significantly content (x) are 1.62-1.36nm x = 0.01 which small enough produce appropriate high density recording media. particle siz...
