  • Publication number: 20160248113
    Abstract: An anion transport membrane is provided, which is based on a linear polymer electrolyte with anion-exchange groups that mechanically reinforced by a covalently cross-linked network. The linear polymer electrolyte is partially or fully miscible with the second covalently cross-linked network. In another example, an anion transport membrane is provided, which is based on a linear quaternary ammonium polysulfone membrane backbone mechanically reinforced by a chemically-crosslinked network of poly(styrene-co-divinylbenzene), whereby the reinforcing network has covalent divinylbenzene cross-links.

  • Patent number: 9233345
    Abstract: An anion transport membrane is provided enabling efficient anion exchange across the membrane, which could be used in applications like fuel cells, water electrolyzers, or water filtration systems. The structural membrane morphology is based on a hydrophobic polysulfone membrane backbone and co-grafted thereon hydrophilic poly(ethylene glycol) grafts and anion conducting quaternary ammonium species. This structure defines a bi-continuous morphology with locally phase-separated hydrophobic-hydrophilic domains, and a co-localization of the anion conducting quaternary ammonium species with respect to the hydrophilic poly(ethylene glycol) grafts enabling efficient and continuous ion transport channels for facilitating anion transport.

  • Publication number: 20130074205
    Abstract: This invention provides transgenic plant cells with recombinant DNA for expression of proteins that are useful for imparting enhanced agronomic trait(s) to transgenic crop plants. This invention also provides transgenic plants and progeny seed comprising the transgenic plant cells where the plants are selected for having an enhanced trait selected from the group of traits consisting of enhanced water use efficiency, enhanced cold tolerance, increased yield, enhanced nitrogen use efficiency, enhanced seed protein and enhanced seed oil. Also disclosed are methods for manufacturing transgenic seed and plants with enhanced traits.
