    摘要： Electrostatographic carrier materials having low bulk densities and high magnetic permeabilities are obtained by impregnating low density imbibitive polymer particles with magnetic or magnetically attractable metal or metal oxide. The low density magnetic composite carrier particles are prepared by the solution phase thermal decomposition of transition metal carbonyls in the presence of the polymer particles with a suitable suspending medium. Air and moisture are excluded from the reaction vessel and the contents are heated with stirring so that the carbonyl boils and the mixture is refluxed until the temperature rises to that of the suspending medium whereupon the polymer particles are impregnated within their pores with elemental metal. The mixture is cooled, the beads washed, air dried, and recovered. When mixed with toner particles and employed in electrostatographic development of electrostatic latent images, the aforementioned carrier materials provide significantly reduced toner impaction levels and longer useful life.

    摘要： Transparent colored materials having low bulk densities and high magnetic permeabilities are obtained by encasing silicaceous particles in a sheath of magnetic or magnetically-attractable metal, which are then heat-treated. The magnetic composite particles are prepared by the solution phase thermal decomposition of transition metal carbonyls in the presence of the silicaceous particles with a suitable suspending medium. Air and moisture are excluded from the reaction vessel and the contents are heated with agitation so that the carbonyl boils and the mixture is refluxed until the temperature rises to that of the suspending medium whereupon coating of the silicaceous particles with elemental metal is complete. The mixture is cooled, the beads washed, air-dried, and recovered. The metal coated particles are then heated in an ambient atmosphere for between about 2 to about 120 minutes at a temperature of from between about 50.degree. C. and 700.degree. C. Particles having transparency, color, and magnetism in the same body are obtained.

    摘要： A method of forming polymeric microspheres for biomedical applications includes forming polymeric microspheres by an emulsion/aggregation process from a precursor monomer species, and treating the polymeric microspheres to attach a biomedical functional material to the polymeric microspheres, where the polymeric microspheres have an average particle diameter of from about 1 to about 15 microns with a narrow particle geometric size distribution. The biomedical functional material may be, for example, a radioactive material, a radioactive precursor material, a bioactive agent, or a ligand.

    摘要： A device for applying an electrical charge to a charge retentive surface by transporting ions in a fluid media and transferring the ions to the member to be charged across the fluid media/charge retentive surface interface. The fluid media is positioned in contact with a charge retentive surface for depositing ions onto the charge retentive surface. In one specific embodiment, the fluid media is a ferrofluid material wherein a magnet is utilized to control the position of the fluid media, which, in turn, can be utilized to selectively control the activation of the charging process.
