This work reports on the effect of the 1,2-hexadecanediol content on the structural and magnetic properties of CoFe2O4 nanoparticles synthesized by thermal decomposition of metal-organic precursors in 1-octadecene. Although pseudo-spherical particles having an average size of about 8 nm and similar stoichiometry have been observed in all studied samples, a high level of variability in the cryst...

In this research work cobalt-ferrite (CoFe2O4) nanoparticles were synthesized by a simple, general sol-gel auto-combustion method. For this study, electromagnetic (EM) wave absorbing coatings with different weight fractions of nano-carbon and CoFe2O4 (which, arises from both dielectric and magnetic contributions) and polymeric epoxy resin were prepared and their characteristics were fully inves...

Single phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation followed mechanochemical treatment, microemulsion and microwave hydrothermal synthesis. The CoFe2O4 samples have been studied using a variety characterization techniques: X-ray diffraction (XRD), Raman spectr...

Phosphorylation plays pivotal roles in cellular processes and dysregulated phosphorylation is considered as an underlying mechanism in many human diseases. Top-down mass spectrometry (MS) analyzes intact proteins and provides a comprehensive analysis of protein phosphorylation. However, top-down MSbased phosphoproteomics is challenging due to the difficulty in enriching low abundance intact pho...

in this work, we investigated synthesis, magnetic properties of silica coated metal ferrite, (cofe2o4)/sio2 and manganese doped cobalt ferrite nanoparticles (mnxco1-xfe2o4 with x= 0.02, 0.04 and 0.06)/sio2 for possible biomedical application. all the ferrites nanoparticles were prepared by co-precipitation method using fecl3.6h2o, cocl2.6h2o and mncl2.2h2o as precursors, and were silica coated ...

Transition metal ferrites such as CoFe2O4, possessing a large magnetostriction coefficient and high Curie temperature (Tc > 600 K), are excellent candidates for creating magnetic order at the nanoscale and provide a pathway to the fabrication of uniform particle-matrix films with optimized potential for magnetoelectric coupling. Here, a series of 0-3 type nanocomposite thin films composed of fe...

We synthesized CoFe2O4 nanoparticles using heating in various times by simple microwave method at power about 600W. Water, ethylene glycol and their combination were used as solvent. X-ray diffraction pattern(XRD) analysis was performed for evaluation of structural characterization of samples. We also used scanning electron microscopy (SEM) to evaluate the effects of various parameters of heati...
