  • Patent number: 10428186
    Abstract: Multi-component particles comprising inorganic nanoparticles distributed in an organic matrix and processes for making and using same. A flowing aerosol is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains a liquid vehicle and at least one precursor. At least a portion of the liquid vehicle is removed from the droplets of precursor medium under conditions effective to convert the precursor to the nanoparticles or the matrix and form the multi-component particles.
    Type: Grant

  • Patent number: 7116467
    Abstract: A structured fluid composition comprising: (a) a low refractive index liquid; (b) particles including light absorbing charged particles such as pigments, non-light absorbing uncharged particles such as teflon, silica, alumina and combinations thereof; and (c) at least one additive selected from the group consisting of a dispersant, a charging agent, a surfactant, a flocculating agent, a polymer, and combination thereof; for use in a TIR electronic display. The inventive composition improves the long-term stability, response time and visible appearance of image displays which electrophoretically frustrate total internal reflection (TIR).

  • Publication number: 20040262237
    Abstract: This invention relates to a process for separating particulates from a low dielectric fluid containing such particulates, the process comprising: contacting the particulates with an acidic organic compound, a metal salt of an acidic organic compound, a basic organic compound, or a mixture of two or more thereof; applying an electric field to the low dielectric fluid; forming a particulates-lean phase and a particulates-rich phase in the dielectric fluid; and separating the particulates-lean phase from the particulates-rich phase. This process is particularly suitable for separating particulates from the lubricating oil of an internal combustion during the operation of the engine.

  • Patent number: 6794428
    Abstract: A coupler is described for use in carbon black filled rubber compositions. The coupler includes an amine group and a thiol group or a polysulfidic linkage. The coupler improves the interaction of the carbon black with the rubber as measured by a decrease in the tan delta at 60° C. while substantially maintaining the tan delta at 0° C.
