  • Patent number: 9567502
    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.

  • Patent number: 9529062
    Abstract: A liner for a bore of a waveguide is provided. The liner as an aperture passing through it and is formed of a metamaterial that has a relative electrical permittivity that is negative and near zero. When the liner is installed in the waveguide, it lowers the cutoff frequency of the waveguide while allowing the waveguide to remain hollow. This liner can be used in the bore of an MRI machine to lower the cutoff frequency of the bore of the MRI machine to allow the MRI machine to operate using waves having a lower frequency that if the liner was not used.

  • Publication number: 20160346436
    Abstract: The invention provides compositions for the inhibition of bacterial adhesion. The composition can include nanocrystalline cellulose (NCC) and a water-soluble polymer, which form an NCC hydrogel in water. The NCC hydrogel can be used to treat or coat devices such as a catheter, whereby the NCC hydrogel inhibits bacterial adhesion to the catheter surface to thereby inhibit biofilm formation and growth of bacteria on the catheter surface. The compositions and devices can thus be useful for inhibiting or preventing conditions such as urinary tract infections.

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.
