  • Publication number: 20250108071
    Abstract: 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.

  • Publication number: 20250042812
    Abstract: A method for producing carbon negative supplementary cementitious materials utilizing a carbon mineralization-based direct air capture process. One version of the method comprises pre-treating a mineral feedstock with an alkaline solution, resulting in a pre-treated feedstock and an alkaline solution comprising dissolved alumina or silica. The pre-treated feedstock has enhanced carbonation reactivity in the subsequent carbon mineralization-based direct air capture process. Another version of the method comprises post-treating precipitates yielded from carbon mineralization-based direct air capture process of a mineral feedstock with an alkaline solution, resulting in a residue and an alkaline solution comprising dissolved alumina or silica. The alkaline solutions resulted from the pre- and post-treatments can be directly used as supplementary cementitious materials, or as a sorbent solution for carbon capture.

  • Publication number: 20250042811
    Abstract: A method for producing carbon negative cementitious materials utilizing a carbon mineralization-based direct-air capture process. The method comprises a mineralization step wherein a mineral feedstock is contacted with an aqueous carbonate solution at a high initial pH to form a carbonated feedstock containing reactive silica, along with an alkaline solution containing dissolved aluminum. The resulting alkaline solution is then contacted with gaseous carbon dioxide to form a carbonate solution that can be recycled for use in the mineralization step. The dissolved aluminum in the alkaline solution precipitates during carbon dioxide capture and is subsequently redissolved in a hydroxide solution to form alumina. The alumina can be combined with the carbonated feedstock to create geopolymer concrete.

  • Patent number: 11559767
    Abstract: 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.
