    Assignee: University of Nebraska—Lincoln
    Inventors: David B. Berkowitz, Sylvain Broussy
  • Patent number: 7767388
    Abstract: A method for monitoring the stereoselectivity of at least one organic chemical reaction and the relative rate of at least one organic chemical reaction, wherein the reaction produces a product that can exist as at least two stereoisomers, is provided herein. Also disclosed are methods for identifying and preparing catalysts for the above reactions.
    Type: Grant

  • Patent number: 6974665
    Abstract: A biphasic process for rapid screening of organic reactions comprising monitoring relative rates of parallel organic reactions. The screening process is suitable to determine the efficacy of different reactants, process conditions, and process enhancers such as catalysts or promoters. The biphasic process also allows multiple samples to be analyzed/monitored simultaneously. In addition because enzymes are used to monitor the reaction product in this invention, when that product is chiral and an enantio-discriminating enzyme is used to monitor the product, in addition to the relative rates, enantioselectivities of a set of parallel organic reactions can also be determined.
    Type: Grant

    Date of Patent: December 13, 2005
    Assignee: University of Nebraska

  • Patent number: 5392400
    Abstract: A collaborative computing method and system are described. Output data from and input data for an application program are shared among all of the computers connected in a network using the X protocol. The output from the application program is intercepted and then replicated on each of the computers' displays. Input data for the application program can be read from any of the computers participating in the session. The identifying data associated with the output and input is modified so that each computer can operate as if it were the only computer controlling the application. The session is controlled by displaying on each computer's display a control window which allows the users to invoke a shared application and to use tools such a pointer, marker, to manage a collaboration session. Each user has equal collaborative capabilities in a session. This collaborative method provides a symmetric sharing among all users. A scratch pad window may be created on each computer's display.
