  • Patent number: 6887517
    Abstract: A new class of surface modified particles and a multi-step Michael-type addition surface modification process for the preparation of the same is provided. The multi-step Michael-type addition surface modification process involves two or more reactions to compatibilize particles with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through reactive organic linking groups. Specifically, these reactive groups are activated carbon—carbon pi bonds and carbon and non-carbon nucleophiles that react via Michael or Michael-type additions.

  • Patent number: 6878446
    Abstract: A method for coating particles and the coated particles obtained thereby are disclosed. The particles are first placed in a solution of a first monomer that forms a self-assembling monolayer on the particles thereby forming coated particles. The coated particles are then suspended in a second solution that includes a chemical species and an initiator for oxidative polymerization. The chemical species has a higher oxidation potential than the monomers. In addition, the chemical species form a homopolymer in the presence of the initiator that is covalently bound to the first monomers. Particles of semiconductors such as TiO2, SiO2, SnO2, Al2O3 can be coated with polymers that alter the bandgap energy of the semiconducting particles and/or provide other useful surface chemistries.

    Abstract: The present invention is for particulate compositions and methods for producing them that can absorb or scatter electromagnetic radiation. The particles are homogeneous in size and are comprised of a nonconducting inner layer that is surrounded by an electrically conducting material. The ratio of the thickness of the nonconducting layer to the thickness of the outer conducting shell is determinative of the wavelength of maximum absorbance or scattering of the particle. Unique solution phase methods for synthesizing the particles involve linking clusters of the conducting atoms, ions, or molecules to the nonconducting inner layer by linear molecules. This step can be followed by growth of the metal onto the clusters to form a coherent conducting shell that encapsulates the core.

  • Patent number: 6542283
    Abstract: A sheet material for use in a gyricon display in which a rotatable element, which has a portion which is capable of being permanently magnetized may be oriented to experience either an attractive force or a repelling force between itself and another magnetized element. The attractive force between the element and the pad serve to latch the element in place and prevent unwanted display changes from taking place while the repellant force serves to trap the element in place for the same reasons. The element may be constructed to be either cylindrically or spherically shaped. Further, the sheet material may also contain soft magnetic material pads which may be arranged to provide multiple latching states as desired.

  • Patent number: 6537611
    Abstract: A machine system and process for producing attrition resistant, controlled release fertilizer is described. In the process, a prewet solution is used to initially coat the plant nutrient to be coated followed by the separate application of the individual components used in the coating. The machine system provides an improved means for uniformly applying a single layer or multiple layers of polymer coatings to the plant nutrient.

  • Patent number: 6517166
    Abstract: A wheel rim includes a transparent adhesive layer provided on the surface of the wheel rim, a light-reflective particle layer which is substantially free of any superimposed or overlapping particles and which is formed by spreading solely and uniformly dry light-reflective particles on the transparent adhesive layer and contacting directly the particles with the transparent adhesive layer, the particles having dimensions larger than the thickness of the transparent adhesive layer so that some of the dry light-reflective particles which do not contact the transparent adhesive layer can be allowed to fall off the transparent adhesive layer by gravity, and a transparent protective layer provided on the light-reflective particle layer.

  • Patent number: 6486099
    Abstract: A microcapsule (or microencapsulated product) having a uniform and smooth coating film and also an excellent performance of gradually liberating the content material is produced at a good particle size distribution while suppressing the occurrence of isolated or aggregated film material, aggregated microcapsules and isolated core material. The production process includes: a first coating step of mixing a water-soluble cationic amino resin and an anionic surfactant in the presence of a hydrophobic core material dispersed in an aqueous medium to coat the dispersed core material with a coacervate of the cationic amino resin and the anionic surfactant; and a second coating step of adding an amino resin prepolymer into an aqueous dispersion liquid containing the coated dispersed core material and polycondensating the amino resin prepolymer to further coat the coated dispersed core material with a polycondensate of the amino resin prepolymer.
