Abstract: A process is provided to produce 2,3,5,6-tetraaminotoluene. Highly pure salts of 2,3,5,6-tetraaminotoluene are produced via reduction of 2,6-diamino-3,5-dinitrotoluene. The 2,3,5,6-tetraaminotoluene salt is precipitated as a clean (>99% purity) product. The salt is a precursor for monomers to make a polybenzimidazole for high performance fibers.
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.
Abstract: The present invention discloses a multi-layer fluoropolymeric film that is useful as a light capture front sheet in solar modules, and more broadly as an antireflection layer.

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.

Abstract: A process is provided for making a reaction product comprising 1-butanol by contacting a reactant comprising ethanol containing a significant amount of water with a decomposed hydrotalcite catalyst. The catalyst may be 1) hydrotalcites which have been thermally decomposed, either partially or fully, to form catalytically active species; 2) combinations of hydrotalcites (optionally containing transition metals) and metal carbonates; and 3) hydrotalcites (optionally containing transition metals) surface-impregnated with a transition metal nitrate, where catalysts 2) and 3) have also been thermally decomposed, either partially or fully, to form catalytically active species. The catalyst, at a selected reaction time, has greater activity when the ethanol contains water as compared to when the ethanol is anhydrous.
