  • Turbo-compounding system
    Patent number: 11781471
    Abstract: A turbo-compounding system according to an exemplary embodiment of the present invention includes: a turbocharger including a turbine which is rotated by using pressure of exhaust gas discharged from the engine and a compressor which is rotated by using rotation power of the turbine and compresses new external air and supplies the compressed air to the engine; a motor-generator configured to be rotated by using rotation power of the compressor of the turbocharger to generate power or add rotation power to the compressor of the turbocharger; and a control device configured to operate the motor-generator as a motor or a generator according to a current rotation speed of the engine and may collect power wasted from the engine.
    Type: Grant
    Filed: December 9, 2019
    Date of Patent: October 10, 2023
    Assignee: DOOSAN INFRACORE CO., LTD.

  • Fabrication of macroporous polymeric hydrogel microparticles
    Patent number: 11298678
    Abstract: A polymeric hydrogel microparticle that contains polyacrylamide and chitosan, the chitosan uniformly incorporated in a polyacrylamide matrix. The microparticle, having a coefficient variation of 0 to 2% and containing macropores with an average size of 1 to 60 nm, is capable of transporting biomolecules conjugated to it. Also disclosed are a method of fabricating such a microparticle in a micromold via photo-induced radical polymerization and a one-pot method of conjugating biomolecules to polymeric hydrogel microparticles.
