  • Publication number: 20100156780
    Abstract: A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.

  • Publication number: 20100160960
    Abstract: A hydrogel tissue adhesive having increased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide with a water-dispersible, multi-arm amine in the presence of a polyol additive, which retards the degradation of the hydrogel. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, including but not limited to, ophthalmic applications such as sealing wounds resulting from trauma such as corneal lacerations, or from surgical procedures such as vitrectomy procedures, cataract surgery, LASIK surgery, glaucoma surgery, and corneal transplants; neurosurgery applications, such as sealing the dura; as a plug to seal a fistula or the punctum; adhesion prevention to prevent undesired tissue to tissue adhesions resulting from trauma or surgery; and as a hemostat sealant.

  • Publication number: 20100162436
    Abstract: A targeting method is described that allows precise cassette replacement at a previously characterized genetic locus. A target DNA construct containing a pair of incompatible FRT sites flanking a target cassette was introduced into soybean by regular biolistic transformation. Transgenic events containing a single complete copy of the target site were then selected and retransformed with a donor DNA construct containing the identical pair of incompatible FRT sites flanking a donor cassette. Precise DNA cassette exchange happened between the target cassette and the donor cassette via recombinase mediated cassette exchange (RMCE) so that the donor cassette was introduced at the exact genomic site previously occupied by the target cassette. Through repeated RMCE using additional incompatible FRT sites, multiple groups of transgenes can be stacked at the same genomic locus.

  • Patent number: 7740911
    Abstract: This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a layer of primer coating composition, a layer of base coat composition, and a layer of clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer surfacer comprises a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about (a) 40 to 95% by weight of a caprolactone-modified highly branched acrylic polymer having a hydroxyl and/or carboxyl monomer content, all or part of which has been reacted with caprolactone, of about 1 to 65% by weight and a weight average molecular weight of about 10,000 to 150,000; and (b) 5 to 60% by weight of an aminoplast resin crosslinking agent. The composition is essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both.

  • Patent number: 7741083
    Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.
