The manganese ferrite spinel was synthesized by co-precipitation. The nano sized manganese ferrite characterized by X-ray diffraction (XRD), Scanning electron micrograph (SEM), tunneling electron micrograph (TEM) and Energy dispersive X-ray (EDX) techniques. The adsorption ability of malachite green (MG) from the aqueous solution by manganese ferrite was investigated. It was found that pH value...

The atomic level structure of a series of monodisperse single crystalline nanoparticles with a magnetic core of manganese ferrite was studied using X-ray absorption fine structure (EXAFS) and X-ray absorption near edge structure (XANES) techniques at both the Fe and Mn K-edges, and conventional and high resolution transmission electron microscopy (TEM and HRTEM). In particular, insights on the ...

Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4-C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4-C2H6O2 (Nickel zinc ferrite-ethylene glycol), Fe2O4-C2H6O2 (magnetite ferrite-ethylene glycol), NiZnFe2O4-H2O (Nickel zinc ferrite-water), MnZnFe2O4-H2O (manganese zinc ferrite-water), and Fe2O4-H2O (magnetite fe...

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomateri...

Manganese ferrite nanoparticles were produced by applying the combustion technique using the manganese acetate and ferric nitrate as the starting material. Analytical techniques like FESEM and TEM were utilized to characterize the synthesized materials. The typical size was observed in the range of 12 to 14 nm with a cubic structure. The synthesized material was used as an electrochemical senso...

The microstructural evolution of Fe–0.2C–5Mn steel during intercritical annealing with holding time for up to 144 hours was examined by TEM and STEM. It was demonstrated by TEM that the martensite lath structure gradually transformed into a lamellar ferrite and austenite duplex structure. The partitioning of manganese from ferrite to austenite was found by STEM. Typical Kurdjumov-Sachs orientat...

These days, environmental pollution, notably water has increasingly caused severe human health problems. The major pollutants are heavy metals. MnFe2O4/GO nanocomposite was prepared in the current work via situ method and tested to remove lead ion Pb2+ neutral red (NR) dye from water. characterized using different techniques, including X-ray diffraction, transmission electron microscopy, Fourie...

There is an increased interest in the development of high performance microwave shielding materials against electromagnetic pollution in recent years. Barium ferrite decorated reduced graphene oxide (BaFe12O19@RGO) nanocomposite was synthesized by a high energy ball milling technique and its electromagnetic properties were investigated in the frequency range of 12.4-18 GHz (Ku band). The result...

Magnetic properties of nanocomposite materials obtained by dispersing barium ferrite nanoparticles within polystyrene-butadiene-styrene block copolymer, in the temperature range, 300 to 500 K are reported. The temperature dependence of the magnetization at saturation, averaged uniaxial magnetocrystalline anisotropy, and coercive field of thick films are analyzed. A "matrix effect" was noticed w...
