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...

Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration  levels. X-ray diffraction (XRD) was used  to  investigate  the  films  crystal  structures. The  results  indicate that  if  the  Co  concentration  is  less  that  the  Fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the C...

In this study, we investigate the trajectory of magnetic nanoparticle flowing through a microvessel in presence cylindrical magnet. By using equation motion particle and fluidic forces, is calculated. Our numerical results show that probability trapping particles straight function intensity field, radius, magnetization, diameter vessel. effect magnet saturation magnetization vessel radius on Th...

In this work, we study the magnetization of two types particles a composite consisting polystyrene and multilayer graphene chemically bonded to it, obtained by magnetic separation initial composite. For needle-shaped particles, ferromagnetic type was observed for first time, with values saturation that are large graphene. flat, macroscopic composite, superposition several contributions observed...

Magnetic nanoparticles (MNPs) are very important systems with potential use in drug delivery systems, ferrofluids, and effluent treatment. In many situations, such as in biomedical applications, it is necessary to cover inorganic magnetic particles with an organic material, such as polymers. A superparamagnetic nanocomposite Fe3O4/poly(maleic anhydride-co-acrylic acid) P(MAH-co-AA) with a core/...
