Facile synthesis of high magnetization long term stable bimetallic FeCo nanoparticles
In this study, we reported a facile synthesis of bimetallic FeCo nanoparticles (Fe-Co NPs) by FeSO4.7H2O and Co(Ac)2.4H2O in the presence of sodium borohydride and 2-thiotic acid. The structure and morphology of the nanoparticles were characterized by X-Ray Diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), and Transmission Electron Micros...
متن کاملSynthesis and stabilization of FeCo nanoparticles.
FeCo alloys are an important soft magnetic material because of their unique magnetic properties including large permeability and very high saturation magnetization. FeCo nanoparticles are ideal building blocks for nanostructured thin film or bulk magnetic materials1-3 and are also suitable for biomedical applications.4 However, synthesis of monodisperse FeCo nanoparticles remains a challenging ...
متن کاملNanocarbon synthesis by high-temperature oxidation of nanoparticles.
High-temperature oxidation of silicon-carbide nanoparticles (nSiC) underlies a wide range of technologies from high-power electronic switches for efficient electrical grid and thermal protection of space vehicles to self-healing ceramic nanocomposites. Here, multimillion-atom reactive molecular dynamics simulations validated by ab initio quantum molecular dynamics simulations predict unexpected...

متن کاملChemical Synthesis of High-Stable Amorphous FeCo Nanoalloys with Good Magnetic Properties
It is difficult to fabricate high-purity amorphous FeCo alloys by traditional physical methods due to their weak glass forming ability. In this work, the fully amorphous FeCo nanoalloys with high purity and good stability have been prepared by a direct chemical reduction of Fe2+ and Co2+ ions with NaBH₄ as the reducing agent and polyvinylpyrrolidone (PVP) as the surfactant. The morphologies, su...
