  • Patent number: 11215592
    Abstract: There is provided a separation method in which a target component in a solution can be separated simply but safely and efficiently without contamination from the environment. This method includes: providing a solution containing a target component, and a reaction reagent; while continuously feeding the solution and the reaction reagent to a flow path, intermittently injecting bubbles into the flow path to produce a gas-liquid slug flow in which a mixed liquid containing the solution and the reaction reagent is segmented into a plurality of droplets by the bubbles; continuing the feed of the gas-liquid slug flow in the flow path, thereby facilitating the mixing of the solution and the reaction reagent, and the gasification of the target component by the mixing, in each droplet, and the movement of a target component-derived gas produced by the gasification to the bubbles; and recovering the target component-derived gas with an absorbing liquid.
    Type: Grant
    Filed: November 27, 2019
    Date of Patent: January 4, 2022
    Assignees: MITSUI MINING & SMELTING CO., LTD., BL TEC K.K.
    Inventors: Makoto Nagaoka, Fumihiro Yoshinaga, Atsumi Koyanagi, Shunichi Hatamoto, Yozo Ishihara, Makiko Kumagai, Takashi Nishimura

  • Patent number: 10751370
    Abstract: The present invention relates to pharmaceutical compositions comprising mesenchymal cells (MSCs) and additional agents for blocking co-stimulation of the immune system. The compositions may optionally further comprise a therapeutic cell, a therapeutic tissue, and/or a therapeutic organ implant. Additionally, the instant invention pertains to medical uses of such compositions in immune-mediated diseases and disorders, in essentially all inflammatory and/or autoimmune diseases and conditions, and also in transplantation-related conditions.
