    摘要： Methods for preparing uniformly sized microparticles, with an optional polymeric coating generally include: 1) providing nanoparticles, preferably having a size of between 1 nm and 100 nm; 2) adding a hydrophobic surface layer to the nanoparticles; 3) making a suspension of the hydrophobic nanoparticles and a polymerization initiator in an hydrophobic solvent; 4) dissolving a monomer in the hydrophobic solvent; 5) making an emulsion by dispersing droplets of the hydrophobic solvent in a continuous aqueous phase with an emulsifier; 6) sizing the first emulsion to provide a second emulsion of the same basic components but in which the droplets are substantially uniform and between 2 and 20 μm in size; 7) evaporating at least a substantial portion of the dispersed hydrophobic droplets to assemble nanoparticles to form microparticles suspended now in the aqueous phase; 8) optionally replacing the first surfactant with a second surfactant, which is preferably a polymerizable surfactant; 9) optionally adding a polymerizable monomer to the aqueous phase and allowing it to adsorb into the microparticle; 10) polymerizing the monomer(s) to provide a polymer layer on the microparticles; and 11) functionalizing the polymer surface layer of the microparticles with one or more polymer, nanoparticle or biological macromolecular layers. In a related method the nanoparticles are provided with a hydrophilic surface layer, and the emulsion is made by dispersing the aqueous nanoparticles in a continuous hydrophobic phase. The microparticles have a polymeric coating and a magnetic core that comprises in excess of 50% of the particle's mass. The polymeric shell may contain one or more functional groups capable of forming chemical bonds useful in managing a variety of separations.

    摘要： A PMA (Permanent Magnet Assisted) synRM and a method for imposing a magnetic force thereon. Magnets are inserted into outer flux barriers of a plurality of flux barriers formed along the radius of a rotor, and bridges or slim portions are formed on inner flux barriers at positions corresponding to the positions of the magnets so that the magnetic force is imposed on the magnets through coils. Since the number of the flux barriers is sufficiently increased while the amount of the magnets consumed is decreased, the PMA synRM has increased efficiency and reduced production costs.
