  2. Magnetic nanoparticles - Wikipedia

    en.wikipedia.org/wiki/Magnetic_nanoparticles

    Magnetic nanobeads or nanoparticle clusters composed of FDA-approved oxide superparamagnetic nanoparticles (e.g. maghemite, magnetite) hold much potential for waste water treatment since they express excellent biocompatibility which concerning the environmental impacts of the material is an advantage compared to metallic nanoparticles.

  3. Nanofluid - Wikipedia

    en.wikipedia.org/wiki/Nanofluid

    A 2013 study considered the effect of an external magnetic field on the convective heat transfer coefficient of water-based magnetite nanofluid experimentally under laminar flow regime. It obtained up to 300% enhancement at Re=745 and magnetic field gradient of 32.5 mT/mm. The effect of the magnetic field on pressure was not as significant. [42]

    Droplet formation using a flow focusing device. [17] Diagram of flow focusing droplet formation device commonly used in microfluidic devices. Liquid flowing in from the left is pinched off into droplets by an oil flowing in from the top and bottom. [10] Two stream reagent addition using a flow focusing approach with a planar chip format.

  5. Iron oxide nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide_nanoparticle

    Water-in-oil is more popular for synthesizing many kinds of nanoparticles. The water and oil are mixed with an amphiphillic surfactant. The surfactant lowers the surface tension between water and oil, making the solution transparent. The water nanodroplets act as nanoreactors for synthesizing nanoparticles. The shape of the water pool is spherical.

  6. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    The magnetic attraction of tiny nanoparticles is weak enough that the surfactant's Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually do not retain magnetization in the absence of an externally applied field and thus are often classified as " superparamagnets " rather than ferromagnets.

  8. Magnetite - Wikipedia

    en.wikipedia.org/wiki/Magnetite

    One use is in water purification: in high gradient magnetic separation, magnetite nanoparticles introduced into contaminated water will bind to the suspended particles (solids, bacteria, or plankton, for example) and settle to the bottom of the fluid, allowing the contaminants to be removed and the magnetite particles to be recycled and reused ...
