  • Publication number: 20240139718
    Abstract: The present invention is a perovskite metal oxide catalyst substituted with metal ions for reducing carbon deposition, a method for producing the same, and a process for performing a methane reforming reaction using this catalyst. The catalyst is produced in which Ni in ionic form is substituted at a portion of the Ti site of SrTiO3, MgTiO3, CaTiO3, or BaTiO3, which is a multi-component metal oxide having a perovskite structure. Then, various methane reforming reactions (steam-methane reforming, dry reforming of methane, catalytic partial oxidation of methane) may be efficiently and economically performed using this catalyst. The nickel-substituted perovskite metal oxide catalyst has a structure in which Ni2+ is substituted in the perovskite lattice structure. Thus, the metal oxide catalyst has advantages in that carbon deposition thereon does not occur, and thus, the catalyst has a high catalytic stability and may be used for a long time.

  • Patent number: 11946051
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating hypertrophic scars. The present inventors have found that the inhibition of expression of TXNDC5, PRRC1, S100A11, Galectin 1, Filamin A, eIF-5A, Annexin A2, and FABP5 can be a new target for improving and treating hypertrophic scars. In the present invention, TXNDC5-, PRRC1-, S100A11-, Galectin 1-, Filamin A-, eIF-5A-, Annexin A2-, and FABP5-specific siRNAs were constructed to determine the probability of treating the hypertrophic scars. As a result, the knockdown of the protein or a gene encoding the protein induces apoptosis in the hypertrophic scars and reduces collagen expression, which can be very useful in treating wounds.
