Doping of Nano Zinc  Ferrites by Chromium: Structural and Magnetic Properties Studies
A SERIES OF CHROMIUM-SUBSTITUTED ZINC FERRITES (CRXZN FE2-XO4 WITH = 0.00, 0.10, 0.20, 0.30, 0.40) WERE SYNTHESIZED VIA HYDROTHERMAL METHOD. THE STRUCTURAL CHARACTERIZATIONS OF ALL THE PREPARED SAMPLES WERE DONE USING XRD, FTIR AND EDAX, TEM, HR-TEM AND TGA MEASUREMENTS . THESE STUDIES CONFIRMED THE FORMATION OF SINGLE-PHASE INVERSE SPINEL STRUCTURE IN ALL THE COMPOSITIONS. FROM HR-TEM MEASURMENTS, CRYSTALLINITY ARE ... إقراء المزيد

A Robust Synthesis of Magnetite Nanoparticles of Desired Size and the Functionalization Thereof
The synthesis of magnetite nanoparticles is an area of permanent interest in view of their high technological applications including Biomedicine and Biosensing. These nanoparticles are used as enhanced magnetic resonance imaging (MRI) agents, for biological separation and magnetic drug delivery systems, and magnetic hyperthermia treatment [1]. Magnetite nanoparticles of about 20 nm in diameter and low polydispersity were prepared heating ... إقراء المزيد
