  • Patent number: 10131874
    Abstract: A cell culture support comprising a substrate, and a dual stimuli responsive block copolymer immobilized on the substrate, wherein the dual stimuli responsive block copolymer is both thermoresponsive and pH responsive. A method of culturing cells comprising the cell culture support having a dual stimuli responsive copolymer immobilized on a substrate, wherein the dual stimuli responsive copolymer is thermoresponsive and pH responsive; and growing the cells on the cell culture support. By lowering the temperature, cells are released from the cell culture support.
    Type: Grant
    Filed: September 12, 2016
    Date of Patent: November 20, 2018
    Assignee: GENERAL ELECTRIC COMPANY
    Inventors: Reginald Donovan Smith, Prameela Susarla, Slawomir Rubinsztajn, Brian David Polizzotti, Anton Beletskii
  • Patent number: 9709549
    Abstract: Method and systems, for processing biological material, that contain a biological material in a vessel; add an aggregating agent to the material in the vessel and allow the material to separate into two or more distinct submaterials; extract one or more of the submaterials from the vessel; automatically transport one or more of the submaterials remaining in the vessel to a filtration device; and collect a resulting target retentate into a target retentate receptacle.

  • Publication number: 20070045189
    Abstract: Acid mine demineralization methods wherein the acid mine drainage is neutralized, clarified, and forwarded to a microfiltration unit. The so filtered drainage water is then forwarded to a reverse osmosis unit. The permeate from the reverse osmosis unit is characterized by reduced sulfate, silica, calcium, aluminum, iron, magnesium, and manganese levels. Additionally, improvement in reduction of total dissolved solids is noted.
