  • Magnetic nanoparticle cellulose material
    Patent number: 8785623
    Abstract: The present invention relates to ferromagnetic materials based on nano-sized bacterial cellulose templates. More specifically, the present invention provides an agglomerate free magnetic nanoparticle cellulose material and a method of forming such magnetic nanoparticle cellulose material. Further, the magnetic nonoparticles are physically attached on the cellulose material and evenly distribute.

  • Adherent silicones
    Patent number: 6652975
    Abstract: A process for forming a composition includes providing a liquid mixture that includes silicone oligomers and silsesquioxane oligomers and curing the liquid mixture to form a composition of first and second polymers. The first polymer includes the silsesquioxane oligomers cross-linked by siloxane bonds. The second polymer includes a cross-linked network formed in part of the silicone oligomers.

  • Formation of gratings in optical fibers coated with UV-curable polymer
    Patent number: 6396983
    Abstract: This invention is predicated upon applicants' discovery that UV-induced gratings can be formed through polymer coatings that include conjugated double bonds and aromatic moieties. Coatings with low concentrations of aromatic-containing free-radical photoinitiators provide both reasonable curing speeds and sufficient transparency that gratings can be written through them. Moreover some of these aromatic-containing free-radical photoinitiators act synergistically with non-aromatic ketone photoinitiators. Advantageous aromatic-containing free-radical photoinitiator concentrations are in the range 0.01%-0.1% and preferably in the range 0.02% to 0.05%. Advantageous polymer coatings are acrylate-based coatings.
