Abstract:
The disclosure provides a process for preparing a self-dispersing pigment having an isoelectric point of at least about 8 comprising: (a) adding a dual functional compound with an acidic aluminum salt to form an aqueous solution, wherein the dual functional compound comprises an anchoring group that attaches the dual-functional compound to the pigment surface, and a basic amine group comprising a primary, secondary or tertiary amine; (b) adding a base to the mixture from step (a) whereby the pH is raised to about 4 to about 9 to form a turbid solution; and (c) adding the mixture from step (b) to a slurry of inorganic particles whereby a hydrous alumina and the dual functional compound are deposited on the pigment surface. The self-dispersing pigments prepared by this process are useful in making décor paper that may be used in paper laminates.
Abstract:
Disclosed herein are curable compositions comprising a free radical curable fluoroelastomer, a free radical generating compound and an unsaturated metal compound coagent. Such compositions cure well, exhibit good (i.e. low) compression set resistance and process well (i.e. have reduced polymer viscosity compared to similar compositions not containing the unsaturated metal compound coagent).
Abstract:

Abstract:
A tissue adhesive formed by reacting an aminodextran containing primary amine groups with an oxidized dextran containing aldehyde groups is described. The dextran-based polymer tissue adhesive is particularly useful in medical applications where low swell and slow degradation are needed, for example sealing the dura, ophthalmic procedures, tissue repair, antiadhesive applications, drug delivery, and as a plug to seal a fistula or the punctum.
Abstract:
An OLED electronic device contains a fullerene chemically bonded to a hole transport layer. The bonding of the fullerene to the hole transport layer improves device lifetime and prevents migration of the fullerene to adjacent layers where deleterious effects may result.
Abstract:
A process for patterning thick film electrically functional patterns using a photosensitive polymer layer. A tacky photosensitive layer is applied onto a substrate surface. The photosensitive layer is imaged with a pattern using actinic radiation, the exposed areas of the photosensitive layer become hardened and non-tacky. A subsequent application of a thick film composition sheet will cause the thick film to adhere to the remaining tacky areas. Upon peeling the sheet, a thick film print pattern will be produced. This step is followed by a processing profile prescribed by the thick film composition used which results in a pattern having electrically functional properties. The invention also extends to a process wherein a thick film composition is recovered from a used sheet.
Abstract:
An E. coli host strain was engineered wherein genes adhE, IdhA, frdB, and pfIB were disrupted and novel butanol dehydrogenase gene, sadB, from Achromobacter xylosoxidans, was added to produce the isobutanol production host.
Abstract:
This invention relates to polynucleotide sequences encoding a gene that can confer resistance to at least one herbicide. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to at least one herbicide, and methods of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently select the best lines for breeding strategies by avoiding sensitive lines.
Abstract:
The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a root-preferred promoter for the gene encoding Cyclo1. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequences disclosed herein is provided. The method comprises stabling incorporating into the genome of a plant cell a nucleotide sequence operably linked to the root-preferred promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence. The present invention also relates to isolated nucleic acids encoding plant cyclotides. The invention relates to the construction of a chimeric gene encoding all or a portion of the plant cyclotides, in sense or antisense orientation, wherein expression of the chimeric gene results in the production of altered levels of plant cyclotides in a transformed host cell.
