Patent number: 11559767Abstract: A method of sequestering gaseous carbon dioxide in which an oxide is carbonated by contacting it with a first aqueous carbonate solution to convert a portion of the oxide into a carbonate, which precipitates from solution. By converting the oxide to a solid carbonate, the CO2 from the first carbonate solution is sequestered into the precipitate. At the same time, an aqueous hydroxide solution is formed. The aqueous hydroxide solution is contacted with gaseous carbon dioxide which sequesters the gaseous CO2 into a second aqueous carbonate solution. The second solution so generated is then recycled back into the process and used to convert the oxide into the precipitated carbonate.Type: GrantFiled: May 12, 2021Date of Patent: January 24, 2023Assignee: Wisconsin Alumni Research FoundationInventors: Bu Wang, Raghavendra Ragipani

Publication number: 20190111082Abstract: The present invention provides methods for inducing tolerance and/or suppressing an immune response to an antigen by passing a cell suspension containing an anucleate cell through a constriction, wherein the constriction deforms the cell thereby causing a perturbation of the cell such that an antigen and/or tolerogenic factor enters the cell. In some embodiments, the anucleate cell is delivered to an individual and the antigen is delivered to and processed in a tolerogenic environment to induce tolerance and/or suppress an immune response to the antigen.Type: ApplicationFiled: May 3, 2017Publication date: April 18, 2019Inventors: Jonathan B.
