  • Pollen tube stimulants from pistils
    Patent number: 8389728
    Abstract: This disclosure relates, inter alia, to stimulants of pollen tube germination and growth of pollen tubes, and methods of their use to stimulate in vitro and in vivo pollen germination and pollen tube growth.
    Type: Grant
    Filed: March 26, 2010
    Date of Patent: March 5, 2013
    Assignee: The Arizona Board of Regents
    Inventors: Yuan Qin, Ravishankar Palanivelu, Ronald J. Wysocki, Jr., Arpad Somogyi, Yelena Feinstein
  • PROCESS FOR PREPARATION OF CALCIUM THIOSULFATE LIQUID SOLUTION FROM LIME, SULFUR, AND SULFUR DIOXIDE
    Publication number: 20110262343
    Abstract: An efficient batch or semi-continuous method of production of relative high concentration, low byproduct-containing, calcium thiosulfate (CaS2O3) from lime, sulfur or calcium polysulfide, and sulfur dioxide under elevated reaction temperature conditions is described. The product is an emulsion of liquid calcium thiosulfate and solid byproducts. Under the conditions of the art, including the mole ratios of lime to sulfur, the temperature of the reaction process and the sulfur dioxide reaction conditions, including rate and duration, the byproducts are reduced to about 2% by weight.

  • Electrochromic devices
    Patent number: 6906842
    Abstract: The invention includes many applications for electrochromic devices that require neutral colors and patterned electrodes. It uses novel materials, ways of making the materials, device configurations and applications. In one aspect, the device also includes electrical leads (115,116), transparent conductor layers (135,136), patterned EC layers (143,144), an etch line (99) and a substrate (125).
