  • Patent number: 11333300
    Abstract: A high pressure tank is provided. The high pressure tank provides improved strength and stiffness by optimizing a laminating pattern and a structure of a fiber reinforced plastic that forms a dome portion of the high pressure tank used in a fuel tank of a fuel cell vehicle. The fiber reinforced plastic having relatively high strength is mixed and used for a weak portion of a dome portion of a support layer of a high pressure tank where stress caused by internal pressure of the high pressure tank is concentrated. In particular, bursting strength and stiffness is increased. The usage amount of the fiber reinforced plastic, the number of windings and a thickness by directly reinforcing a weak point of the dome portion are reduced. Accordingly, manufacturing costs of the high pressure tank are reduced.

  • Patent number: 11324706
    Abstract: Disclosed are a composition and a perfume composition for inhibiting growth of breast cancer stem cells containing phenylacetaldehyde or a pharmaceutically acceptable salt thereof as an active (effective) ingredient, and a pharmaceutical composition, a food composition or the like for inhibiting metastasis of breast cancer, or treating or preventing breast cancer, including the composition. The phenylacetaldehyde inhibits growth of breast cancer cells and formation of breast cancer stem cells. In addition, the phenylacetaldehyde inhibits expression of self-renewal genes such as Nanog, Sox2, Oct4, and CD44 known to be specifically expressed in breast cancer stem cells, inhibits production of IL-6 known to be involved in formation of mammospheres of breast cancer stem cells, and inhibits STATS signaling pathways. Accordingly, the compound inhibits growth of breast cancer stem cells and is useful for the treatment of breast cancer.
