  • Three-dimensional bioreactors
    Patent number: 11912971
    Abstract: Design, fabrication and applications of three-dimensional (3D) bioreactor for cell expansion and cell secreted substance production. The bioreactors have relatively low levels of potentially cytotoxic compounds, can be coated with substituted or unsubstituted poly(p-xylene) type coatings and can also be separately formed from liquid crystal photopolymerizable monomers.
    Type: Grant
    Filed: September 2, 2022
    Date of Patent: February 27, 2024
    Assignee: SOUTHWEST RESEARCH INSTITUTE

  • GRAFT COPOLYMERS OF DEXTRAN AND POLYACRYLAMIDE AND METHODS OF MAKING AND USING SAME
    Publication number: 20230399447
    Abstract: Disclosed herein are new graft copolymers of dextran and polyacrylamide. The graft copolymers can include dextran, where the dextran is a backbone polymer including about 15 wt % to about 50 wt % of the graft copolymer; and polyacrylamide, where the polyacrylamide is a side chain polymer including about 50 wt % to about 85 wt % of the graft copolymer, based on the total weight of the graft copolymer, where the graft copolymer has a weight-average molecular weight from about 1,000,000 g/mol to about 1,500,000 g/mol. The graft copolymers of dextran and polyacrylamide can be used as friction reducers for well treatment fluids.
