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 کاملStructure-Enhanced Yield Stress of Magnetorheological Fluids
The yield stress of magnetorheological ͑MR͒ fluids depends on the induced solid structure. Since thick columns have a yield stress much higher than a single-chain structure, we improve the yield stress of MR fluids by changing the fluid microstructure. Immediately after a magnetic field is applied, we compress the MR fluid along the field direction. Scanning electron microscopy images show that p...
متن کاملInverse magnetorheological fluids.
We report a new kind of field-responsive fluid consisting of suspensions of diamagnetic (DM) and ferromagnetic (FM) microparticles in ferrofluids. We designate them as inverse magnetorheological (IMR) fluids for analogy with inverse ferrofluids (IFFs). Observations on the particle self-assembly in IMR fluids upon magnetic field application showed that DM and FM microparticles were assembled int...
متن کاملFerrofluids and Magnetorheological Fluids
Composition, synthesis and structural properties of ferrofluids and magnetorheological fluids are reviewed and compared. The similarities and main differences between the two types of magnetically controllable fluids are outlined and exemplified in the paper. Chemical synthesis and structural characterization of magnetizable fluids for engineering and biomedical applications are thoroughly disc...
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 ...
