  • Interpenetrating Radiation Shield
    Publication number: 20150213909
    Abstract: An interpenetrating radiation shield is presented. The shield comprises an active shield and at least one passive shield. The active shield generates a directional active shield field. The passive shield has an areal density ranging from about 1 g/cm2 to about 1000 g/cm2 and is positioned within the active shield field in a relationship to the active shield wherein a radiation particle having kinetic energy and traversing a path at a rate of speed is deflected by the active shield field as the radiation particle enters the passive shield. The path of the radiation particle is lengthened within the passive shield and the kinetic energy and speed of the radiation particle are decreased within the passive shield.

  • Erosion-resistant silicone coatings
    Publication number: 20040225079
    Abstract: Novel erosion-resistant silicone coatings can include an acetoxylated silane, an alkoxylated silane, and a silanol fluid. These erosion-resistant silicone coatings can be formed from coating compositions. The preparation of coating compositions, application of coating compositions to substrates, and uses of these coatings are also described.
