Introduction. Fe 3 O 4 nanoparticles (Fe 3 O 4 NPs) can play an important role in cancer therapy. Fabrication of Fe 3 O 4 NPs can be carried out by different procedures such as co-precipitation, thermal decomposition, and green synthesis. 1-3 Co-precipitation is a conventional method withthe capability to produce large-scale of Fe 3 O 4 NPs. 4-6 This method still requires improvement. Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite Magnetic nanoparticles grafted with chiral polymer brushes offer an effective way to bridge the gap between heterogeneous and homogeneous catalysis. Herein, we synthesized a series of chiral catalysts immobilized on magnetic Fe3O4 nanoparticles (MNPs) with a controlled shell structure by an efficient method. This involves the synthesis of living Fe3O4 nanoparticles with surface-bound. Synthesis and characterization of Fe 3 O 4 magnetic nanofluid. Javier A. Lopez 1*, Ferney González 2, Flavio A.

Fe 3 O 4 nanoparticles were prepared by the high-temperature thermal decomposition method. Based on the Rietveld refinement, the crystal structure was determin What Are the Uses of Magnetite? Magnetite increases the density of most mixtures in which it is present. This property allows magnetite to be used in the manufacture of heavy concrete, water filtration, coal mining, landscaping and production of certain iron-based chemicals. When magnetite is added to a concrete mix, it produces heavy concrete.
