In this study, we used 0.2C-1.7Si-1.9Mn wt% cold-rolled sheet as the experimental material to prepare Q&P sample with blocky microstructures and QQ&P lath-shaped through processes, respectively. The partitioning behavior of carbon manganese in two samples after intercritical annealing were studied. During annealing, occurred, resulting contents being significantly higher than those ferr...

Combination of the surfactant-free nonaqueous sol–gel approach with the microwave technique makes it possible to synthesize Fe3O4, CoFe2O4, MnFe2O4, and NiFe2O4 nanoparticles of about 5–6 nm and with high crystallinity and good morphological uniformity. The synthesis involves the reaction of metal acetates or acetylacetonates as precursors with benzyl alcohol at 170 C under microwave irradiatio...

Crystalline and nanostructured cobalt (CoFe2O4), nickel (NiFe2O4), zinc (ZnFe2O4) and manganese (MnFe2O4) spinel ferrites are synthesized with high yields, crystallinity and purity through an easy, quick, reproducible and low‐temperature hydrothermal assisted route starting from an aqueous suspension of coprecipitated metal oxalates. The use of water as a reaction medium is a further adva...

Manganese zinc ferrite nanoparticles (MZF NPs) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. To improve the colloidal stability of MZF NPs for biomedical applications, NPs were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (TPP) as crosslinker. The synthesized NPs were characterized by X ray diffraction (XRD) analy...

The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of amylase and protease on to manganese ferrite (MnFe2O4). The metal ferrite was synthesized via a sol – gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnet...
