  • Patent number: 10081805
    Abstract: Bio-regulators from a group of quaternary ammonium moieties modify a gene expression in a plant to induce enhanced growth and robustness. Such bio-regulator may be applied to seeds through coating or encapsulating, to plants through root drenching, spraying and dusting. Bio-regulators may be duel-acting; causing beneficial modification to gene expressions in desirable plants while modifying gene expression in undesirable plants, making them more susceptible to herbicides. Bio-regulators are Ester Compounds, BMIA Compounds or related salts, BMIA Compounds or related salts of those compounds.
    Type: Grant

  • Patent number: 8999890
    Abstract: Bio-regulators from a group of quaternary ammonium moieties modify a gene expression in undesirable plants to inhibit growth and robustness and enhance the effectiveness of herbicides. Such bio-regulator may be applied to plants through seed treatments, root drenching, spraying and dusting, or to soil were desirable crops are planted or will be planted. Bio-regulators may be duel-acting; causing beneficial modification to gene expressions in desirable plants while modifying gene expression in undesirable plants, making them more susceptible to herbicides. Bio-regulators are Ester Compounds, BMIA Compounds or related salts of those compounds.

  • Publication number: 20070251388
    Abstract: Thin layers of a mixed composition are deposited on a porous substrate by chemical vapor deposition in an inert atmosphere at high temperature. The resulting membrane has excellent stability to water vapor at high temperatures. An exemplary membrane comprises an amorphous mixed-element surface layer comprising silica and at least one oxide of additional element, an optional porous substrate on which said surface layer is deposited, and a porous support on which said substrate or mixed-element surface layer is deposited, wherein the permeance of the membrane is higher than 1×10?7 mol m?2 s?1 Pa?1 and the selectivity of H2 over CO, CO2, and CH4 is larger than 100, and wherein the H2 permeance of the membrane after exposure to a stream containing 60 mol % water vapor at 673 K for 120 h is at least 50% of its initial H2 permeance.

  • Patent number: 6527833
    Abstract: A new type of silica-modified membrane has been developed by the high-temperature, atmospheric-pressure CVD of Vycor glass. The new membrane, Nanosil, showed unprecedented selectivity to hydrogen (100%), without loss of permeability compared to the porous Vycor precursor. The membrane also showed high stability under hydrothermal conditions over prolonged time. The suitability of a Rh/Al2O3 catalyst for the methane reforming with carbon dioxide was also demonstrated. The limitations imposed by thermodynamics on methane conversion have been circumvented by the use of membranes to preferentially remove hydrogen during reaction. The shortcoming of the Knudsen mode of diffusion was overcome by the development of the modified porous glass membrane.
