THE STRUCTURAL, IMPEDANCE AND DIELECTRIC A FERRITE CORE OF IRON MANGANITE ITS COMPOSITE. Samples with single-phase MnFeO3 and multiphase MnFeO3/ZnFe2O4 (30/70), MnFeO3/ZnFe2O4/LaMnO3 (30/40/30) have been successfully prepared as ferrite cores by the solid-state reaction method using high energy milling. Crystal structure, surface morphology, impedance, AC-conductivity dielectric quantities, suc...

A sol–gel technique was successfully employed in creating pure and W-substituted zinc ferrite, with nominal compositions of ZnFe2−2xWxO4 (0.0 ≤ x 0.15). For the purposes investigating physical chemical properties generated powders, several analytical techniques were used. In TEM images all compositions, mixed-shaped particles (cubic, spherical, hexagonal) observed. The crystallite size decrease...

Abstract We fabricated nanoparticles of Zn ferrite the chemical formula ZnFe2O4 using auto-combustion technique, and investigated their magnetic spin distribution frequency response to optical excitation. Optical absorption characterization were carried out in UV–Vis IR range, extended on low side down THz domain. The also characterized by X-ray diffraction force microscopy. dielectric constant...

The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of digestives enzymes; amylase, protease and lipase on to Zn-ferrite (ZnFe2O4). The metal ferrite was synthesized via a sol-gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnetic reso...
