• Separation of FeO and Fe O Nanoparticles Using an Inverted

    Precise and efficient separation and purification methods are therefore necessary for proper implementation of nanoparticles. In this thesis, we study the novel use of an arrangement of magnets to separate out two types of nanoparticles from a suspension, one composed of magnetic Fe 3O 4, and the other composed of nearly non-magnetic FeO.
