Magnetic NiFe2O4 nanoparticle (NFNPs) were synthesized by the microwave-assisted method using Tamarindus indica seeds as a green reducing agent’ for better readability. The identification of NFNPs was carried out X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) with energy dispersive analysis (EDX), transmission microscopy (TEM),...

SiO2-coated Cobalt Ferrite (CoFe2O4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of CoFe2O4 nanoparticles in co-precipitation. The effects of SiO2coating on the magnetic properties of CoFe2O4 nanoparticles were investigated. The structural, morphological and magne...

For spintronic devices excited by a sudden magnetic or optical perturbation, the torque acting on the magnetization plays a key role in its precession and damping. However, the torque itself can be a dynamical quantity via the time-dependent anisotropies of the system. A challenging problem for applications is then to disentangle the relative importance of various sources of anisotropies in the...

Stabilization efficiencies of spinel-based construction ceramics incorporating simulated nickel-laden waste sludge were evaluated and the leaching behavior of products investigated. To simulate the process of immobilization, nickel oxide was mixed alternatively with gamma-alumina, kaolinite, and hematite. These tailoring precursors are commonly used to prepare construction ceramics in the build...

Nano-sized crystallites of iron oxide were synthesized by cost effective co-precipitation method. X-ray diffraction pattern indicated that the magnetic nanoparticles were pure Fe3O4 with a spinel structure. The nanoparticles were characterized by X-ray diffraction (XRD), Fourier-Transform Infrared (FT-IR) spectra, Transmission electron microscope (TEM) and magnetization measurement of the nanop...

Nanofluids are composed of nano-sized particles dispersed in a carrier liquid. The present investigation’s aim is to examine theoretically the magneto-thermomechanical coupling phenomena heated nanofluid on stretched surface presence magnetic dipole impact. Fourier’s law heat conduction used evaluate transmission rate fluids ethylene glycol and water along with suspended nanoparticles cobalt–ch...

Studies show that the size of magnetic nanoparticles has an important impact on their properties. So, the possibility of an optimal size for their use in medical applications has been reported. Therefore, in this study, cobalt ferrite nanoparticles were prepared using co-precipitation method  at 80°C; then the powder was annealed  in a furnace at 150, 200, 300, 400, 500 and 600°C to obtain nano...
