  • Patent number: 9018280
    Abstract: A molding composition formulation includes a thermoset cross-linkable 12 to 45 micron polymeric resin. Hollow glass microspheroids are present from 2 to 12 total weight percent. An article formed from such a composition is further strengthened by the addition of a surface activating agent bonded to the surface of the glass microspheroids. Conventional particulate fillers when added to an inventive formulation provide enhanced performance when the filler particle has a size sufficiently small to insert within adjacent microspheroid interstitial voids. An unsaturated polyester resin so formed is particularly well suited for the formation of sheet molding compound formulations.

  • Patent number: 8349453
    Abstract: A metal ion sensor is provided. The metal ion sensor includes a nanoparticle core doped with a first luminescent material and a shell enclosing the nanoparticle core. The shell includes a second luminescent material and binding sites of outer metal ions. The first luminescent material and the second luminescent material emit light with mutually different colors when excited by an excitation source. The luminescence intensity of the light emitted from the second luminescent material varies in accordance with the binding amount of the outer metal ions, such that the emission color of the combined luminescence of the first luminescent material and the second luminescent material is changed.
