[ 1 ] - Application of Image Analysis in the Characterization of Electrospun Nanofibers
In this work, CoFe2O4 nanoparticles have been prepared by co-precipitation technique. The synthesized CoFe2O4 nanoparticles were applied in the preparation of CoFe2O4/Polyacrylonitrile fiber nanocomposites by the electrospinning process. The prepared nanoparticles and nanofibers were characterized using the Scanning Electron ...
[ 2 ] - Hybrid Nanocomposite Based on CoFe2O4 Magnetic Nanoparticles and Polyaniline
CoFe2O4 Magnetic Nano Particles (MNPs) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. Then, a hybrid nanocomposite of polyaniline (PANI)-CoFe2O4 MNPs has been electrodeposited directly on a stainless steel wire by the potentiostatic method. Microscopic images of electrodeposited PANI and PANI-C...
[ 3 ] - A Simple Electrochemical Method for the Rapid Estimation of Antioxidant Potentials of Some Selected Medicinal Plants
Clinical and Epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. These beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. Therefore screening for antioxidant properties of plant extracts has been one of the inte...

[ 5 ] - Morphological and Crystallographic Characterization of Nanoparticles by Granulometry Image Analysis and Rietveld Refinement Methods
The particle size distribution of the resultant cobalt ferrite samples was determined from Scanning Electron Microscopy (SEM) images using the granulometry image analysis method. Results showed the nanosized particles of the samples. The X-Ray Diffraction (XRD) patterns of samples were also analyzed by Rietveld refinement method. The results indicated that the precipitated sample at 95 <sup...
[ 6 ] - سنتز، ارزیابی مورفولوژیکی و خواص نوری نانوذرات فریت‌های روی، منگنز-روی و کبالت-روی
فریت‌های روی ZnFe2O4، منگنز-روی Mn0.5Zn0.5Fe2O4 و کبالت- روی Co0.5Zn0.5Fe2O4 از انواع فریت‌ها با ساختار اسپینل و از جمله مواد نرم مغناطیس هستند. در این پژوهش، هر سه نوع فریت مورد نظر به روش هم‌رسوبی از نمک‌های روی، منگنز، کبالت و آهن در محیط آبی و بدون دخالت حلال‌های ارگانیک سنتز شد. سا...
