  • Patent number: 12161985
    Abstract: An organogel including a base fluid, cetyl alcohol, and a gelling agent provided in an amount to cause the fluid to change from a liquid state to a gelled state at temperatures below at least 25° C. A nanofluid including an organogel and a nanoparticle component which permits the nanofluid to change from a liquid state to a gelled state at temperatures below at least 25° C., the gelled state helping to maintain the nanoparticle component suspended throughout the base fluid; and a method for preparing a gelled nanofluid.

  • Patent number: 11672822
    Abstract: Methods and compositions are provided for preventing and/or treating infection by disrupting interactions at or near the surface of mannosylated pathogens or other pathogens exhibiting carbohydrate-carbohydrate self-interaction, thus enhancing the immune system's ability to recognize and destroy such pathogens. In some forms, carrier molecules are provided to delivering polymers or other molecules capable of disrupting intra-cellular interaction and/or self-interaction of surface markers on cells.

  • Publication number: 20210272656
    Abstract: A method, computer program, and computer system is provided for analyzing chemical mixtures. Data corresponding to a mixture comprising one or more component species is obtained. A parameter corresponding to a species having a largest parameter value within the mixture is determined from among the component species. The parameter associated with the species having the largest parameter value is subtracted from the data. One or more remaining species associated with the mixture are detected.
