The influence of various cations ranging from alkali metals to transition metals according to the periodic table were discussed. The ferrites used were Ni ferrite, Mg ferrite and Zn ferrite having different cation distributions in the spinel lattice. Cations having appropriate ionic radii and valencies are soluble in ferrite. Several additives formed other phase in addition to the spinel phase....

Over the past decade, transition metal-based ferrite nanostructures, displaying MFe2O4 stoichiometry (M2+ cations, e.g., Mn, Co, Ni and Zn), have been devised examined primarily owing to their promising applications in cancer nanomedicine. Among these multi-functional spinel ferrites, manganese (MnFe2O4) deserves special attention because it unveils exciting magnetic properties, high chemical s...

Hybrid nanofluids are new and most fascinating types of fluids that involve superior thermal characteristics. These exhibit better heat-transfer performance as equated to conventional fluids. Our concern, in this paper, is numerically interpret the kerosene oil-based hybrid comprising dissimilar nanoparticles like silver (Ag) manganese zinc ferrite (MnZnFe 2 O 4 ). A numerical algorithm, which ...

HPMC Polymer composites were prepared by doping various concentrations of Zinc ferrite nanoparticles using solution casting method. These polymer composites were characterized using X-Ray Diffraction and conductivity measurements. The addition of nanoferrites in the polymer matrix do change the structural and the AC conductivity properties of the film, which is supported by the results obtained...

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...

The response of the structure of the M-type barium hexaferrite (BaFe12O19) to mechanical action through high-energy milling and its impact on the magnetic behaviour of the ferrite are investigated. Due to the ability of the (57)Fe Mössbauer spectroscopic technique to probe the environment of the Fe nuclei, a valuable insight on a local atomic scale into the mechanically induced changes in the h...

Recent advances in the synthesis of various magnetic nanoparticles using colloidal chemical approaches are reviewed. Typically, these approaches involve either rapid injection of reagents into hot surfactant solution followed by aging at high temperature, or the mixing of reagents at a low temperature and slow heating under controlled conditions. Spherical cobalt nanoparticles with various crys...

Researchers are in continuous search of better strategies to minimize, if not prevent, the anthropogenic release toxic heavy metals, such as Cu(II) and Pb(II), into drinking water resources natural environment. Herein, we report for first time low-temperature combustion synthesis magnetic chitosan-manganese ferrite absence cross-linking agents its removal Pb(II) from single-component metal solu...
