  • Patent number: 11214646
    Abstract: This disclosure is related to a class of metal-ion induced hydrophobic polymers and method of producing such class of compounds by a one-step solution immersion process. Specifically, a metal-ion Induced hydrophobic polymer or melamine sponge (MII-HMS) is disclosed. Such polymer or sponge is demonstrated to be highly hydrophobic and oleophilic and exhibits excellent oil absorption capabilities, being able to absorb a wide range of oils and organic solvents up to 71 to 157 times of its own weight.
    Type: Grant
    Filed: February 15, 2019
    Date of Patent: January 4, 2022
    Assignee: South Dakota Board of Regents
    Inventors: Zhengtao Zhu, Yichun Ding, Daniel Heglund
  • Publication number: 20210393639
    Abstract: The present disclosure relates to compositions and systems for improving tissue perfusion such that blood flow is increased, improving tissue healing time and reducing or eliminating tissue necrosis. In a preferred embodiment, the compositions comprise a phosphodiesterase inhibitor, a calcium channel blocker, a nitric oxide producer, and an ?-adrenergic antagonist. Methods of making the compositions and using the compositions are also disclosed.

  • Patent number: 10429400
    Abstract: The present invention relates to methods of testing medications to evaluate authenticity and identify counterfeits. The testing methods employ a reactive system comprising a solvent and an acid. Optionally, the reactive system can also comprise an organometallic agent. The testing methods can provide rapid results verifying the authenticity of an antimalarial medication. Further the test method can provide clear results that can be implemented and interpreted without special training, anywhere in the world. The test methods can offer quantitative and qualitative results. The test methods are based on reactions that yield different colors where the color can indicate the presence of an active ingredient, and the intensity of the color can indicate the concentration of the active ingredient.
