  • Publication number: 20210369875
    Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.

  • Publication number: 20210230005
    Abstract: A system and method for converting carbon dioxide are proposed. The system for converting carbon dioxide includes a carbon monoxide generator for generating carbon monoxide through a reverse water gas shift reaction and a hydrocarbon generator for producing a hydrocarbon through a Fischer-Tropsch synthesis reaction, whereby the carbon monoxide generator is packed both with a catalyst for the reverse water gas shift reaction and with a catalyst for the Fischer-Tropsch synthesis reaction, thus increasing the CO yield in the carbon monoxide generator even at a low temperature compared to when the catalyst for the reverse water gas shift reaction is used alone, ultimately increasing the hydrocarbon yield in the hydrocarbon generator. Moreover, the energy of the exothermic Fischer-Tropsch synthesis reaction can be used as the energy required for the endothermic reverse water gas shift reaction, thereby increasing energy efficiency and processing yield and thus reducing operation and maintenance costs.
