  • Patent number: 10818932
    Abstract: A gas diffusion layer for a metal-air battery may include a plurality of carbon nanotube thin films that are arranged to be stacked, and the carbon nanotube thin films may include a plurality of first carbon nanotubes arranged in a predetermined direction. The gas diffusion layer for the metal-air battery may include a plurality of carbon nanotube thin films in which a plurality of carbon nanotubes are arranged such that they cross each other by a floating catalyst chemical vapor deposition (“FCCVD”) method.

  • Patent number: 7511023
    Abstract: The present invention relates to an anticancer drug-chitosan complex forming self-aggregates and the preparation method thereof. More precisely, the present invention relates to the anticancer drug-chitosan complex forming self-aggregates in aqueous media composed of a hydrophobic anticancer agent and a hydrophilic chitosan, and the preparation method thereof. The anticancer drug-chitosan complex of the present invention not only works selectively against target tumor tissue but also continues to release the medicine over a long period of time. Besides, the anticancer drug-chitosan complex could have greater amount of drug by adding the anticancer drug into self-aggregates, which is generally limited by chemical bond. Therefore, the anticancer drug-chitosan complex of the present invention can be effectively used for the cancer chemotherapy.
