Cobalt Zinc Ferrite Nanoparticles as a Potential Magnetic Resonance Imaging Agent: An In vitro Study
BACKGROUND Magnetic Nanoparticles (MNP) have been used for contrast enhancement in Magnetic Resonance Imaging (MRI). In recent years, research on the use of ferrite nanoparticles in T2 contrast agents has shown a great potential application in MR imaging. In this work, Co0.5Zn0.5Fe2O4 and Co0.5Zn0.5Fe2O4-DMSA magnetic nanoparticles, CZF-MNPs and CZF-MNPs-DMSA, were investigated as MR imaging co...
Ultrahigh efficient and effective electromagnetic-interference (EMI) shielding composites have been fabricated with the combination of Polyaniline zinc-cobalt ferrites (Co1-xZnxFe2O4, 0.1 ? x 0.4). Ferrite nanoparticles synthesized via sol-gel method were functionalized to polyaniline in situ polymerization. Average crystallite sizes estimated using Debye–Scherrer Rietveld found be between 20-3...
The gel to carbonate precipitate route has been used for the synthesis of Ni1-xZnxFe2O4 (x = 0, 0.25, 0.5 and 0.75) bulk inverse spinel ferrite powder samples. The optimal zinc (50%) substitution has shown the maximum saturation magnetic moment and resulted into the maximum magnetic loss tangent (tanδm) > -1.2 over the entire 2-10 GHz frequency range with an optimum value ~-1.75 at 6 GHz. Ni0.5...
A steel has recently been designed to benefit from the deformation induced transformation of retained austenite present in association with bainitic ferrite. It has as its major microstructural component, dendrites of d-ferrite introduced during solidification. The d-ferrite replaces the allotriomorphic ferrite present in conventional alloys of this kind. The authors examine here the stability ...
The ferrite plating a method synthesizing ferrite films from an aqueous solution -has developed lately as follows; (1) Applying power ultrasound to aqueous solution improves the qualities of ferrite coating on polymer microspheres much, (2) similarity is found between mechanisms of the ferrite plating and bacterial FesO4 ( magnetsome) synthesis, (3) using highly alkaline (pH=13) solution contai...
Bone Tumor Suppression Magnetic bone cement incorporating magnetically soft zinc ferrite nanoparticles and aligned in a direct current magnetic field realized exceptionally high heating power live animals under clinically safe parameters for hyperthermia. of osteosarcoma rabbits by hyperthermia substantially enhances survival rate. More details can be found article number 2104626 Shuli He, Qing...
Nanocomposite zinc ferrites were synthesized using glycine-nitrates by sol–gel auto-combustion technique. The influence of calcination temperatures varying from 400 to 900°C on structural and magnetic properties of spinel ZnFe2O4 powders have been investigated. The characterization measurements including X-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetomet...
Biosynthesis of Zinc Ferrite Nanoparticles Using Polyphenol-rich extract of Citrus aurantium flowers
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...
Magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. The most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (MRI) and heating mediators for cancer therapy. In...
Abstract—Miniaturized ferrite ring patch antennas (RPAs) were designed and fabricated for multiple-input multiple-out (MIMO) applications. Design parameters of higher-order mode ferrite RPAs, 1-RPA and 2-RPA, were optimized, and antenna performance of the ferrite 1-RPA was evaluated. The Z-type hexaferrite and 2%-weight borosilicate glass composite was used for the ferrite antenna disk. The mea...
