  • Patent number: 10533992
    Abstract: Unlike a conventional method for evaluating a degree of ultraviolet protection through visual evaluation, the disclosed method for measuring a sunlight protection function can accurately and objectively measure and determine a degree of sunlight protection by measuring a change due to a material to be measured with respect to an expression amount of skin tissue antimicrobial peptides (AMPs) in skin cells, which decrease from exposure to sunlight, and/or a generation amount of S-nitrosylated protein. Additionally, the disclosed measurement method can determine whether blue/violet light of wavelengths of 400-500 nm, which induces the most skin damage among visible rays, is blocked and provide a more specified sunlight protection effect evaluation result. Moreover, by using the disclosed measurement method, a degree of sunlight protection can be indexed, and a sunlight protection composition for protecting normal skin from the blue/violet light can be provided.

  • Publication number: 20190237750
    Abstract: A method of manufacturing a negative electrode for a secondary battery includes a first step of preparing a lithium metal sheet coated with a lithium metal or to which the lithium metal is adhered in a form of a thin film on a release film and wound into a roll, a second step of laminating the lithium metal sheet to allow the lithium metal to be adjacent to a negative electrode material mixture, to thereby manufacture a negative electrode in which lithium metal is laminated and a third step of applying pressure to the negative electrode. The release film is coated with silicon. The negative electrode manufacturing method uniformly laminates or bonds lithium metal which is difficult to handle on the negative electrode material mixture of the secondary battery and advantageously enhances the speed of the pre-lithiation by using the patterned lithium metal.
