    Abstract: Phosphoranimide-metal catalysts and their role in hydrodesulfurization and hydrogenation are disclosed. The catalysts comprise of first row transition metals such as nickel, cobalt and iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1 and have no inactive bulk phase and no dative ancillary ligands. In one embodiment, the catalysts comprise discrete mixed-valent precatalyst clusters, the electronic state of which can be adjusted to optimize catalytic activity. The catalysts catalyze the hydrodesulfurization of a range of sulfur-containing organic compounds under lower temperature and pressure conditions than those conditions commonly used in industrial hydrodesulfurization. The catalysts also catalyze the hydrogenation of substrates comprising at least one carbon-carbon double bond which is not present in an aromatic moiety, although the substrate itself may include an aromatic moiety.

  • Publication number: 20140316117
    Abstract: The invention is directed to a method for preparing a polymer derived from an animal protein, such as in a feedstock derived from animal by-products. The method involves hydrolyzing proteins present in a feedstock to obtain hydrolyzed proteins, wherein hydrolysis is conducted under conditions sufficient to digest the proteins and destroy pathogens; extracting a protein fraction from the hydrolyzed proteins; and treating the protein fraction with a crosslinking reagent to form the polymer. The crosslinking reagents may include epoxies. The polymer may be further processed to form a thermoset plastic. The polymer may be used as an adhesive, or in the preparation of a natural fiber composite material.

  • Publication number: 20140249051
    Abstract: The present application discloses a system and method for ABO antibody detection and characterization that can provide an alternative means for assessment and management of ABO-incompatible and ABO-compatible transplants. The method and system comprises determining an anti-ABO blood group antigen subtype antibody profile of a subject using a biological sample from the subject. The method and system can be used to evaluate the suitability of a donor blood or tissue product for a recipient subject by comparing the determined anti-ABO antigen subtype antibody profile of the recipient subject with the ABO histo-blood group or ABO histo-blood subgroup of a donor blood or tissue product. In order to define the subject's ABO histo-blood subgroup, the determined antibody profile is compared to known ABO histo-blood group antigen subtype profiles and/or known anti-ABO antigen subtype antibody profiles for ABO histo-blood subgroups to identify the ABO histo-blood subgroup of the subject.

  • Publication number: 20140231379
    Abstract: A nanotip, is fabricated by modifying a precursor nanotip having an apex and a shank by applying an electric field in the presence of a reactive gas to perform field-assisted etching wherein atoms are preferentially removed from the shank by chemical interaction with the reactive gas, and controlling the reactive gas pressure and/or tip voltage to vary the electric field so as to promote field evaporation of apex atoms during fabrication of the nanotip and thereby control the overall profile of the resulting nano-tip. The method permits shaping of the overall tip profile.
