  • Patent number: 10337099
    Abstract: An apparatus and a method for coating an inner wall of a metal tube are provided. The apparatus for coating an inner wall of a metal tube includes mounting posts on which both end openings of a metal tube are mounted and configured to block the inside of the metal tube from the ambient air so that a pressure in the metal tube is adjustable by the vacuum exhaust and inflow of process gases, a sputtering target metal tube installed inside the metal tube coaxially with the metal tube, a pulse electromagnet installed around an outside perimeter of the metal tube coaxially with the metal tube to apply a pulse magnetic field in an axial direction of the metal tube, an electromagnetic pulse power supply unit configured to apply pulse power to the pulse electromagnet, and a sputtering pulse power supply unit configured to synchronize a negative high-voltage pulse with the pulse power applied to the pulse electromagnet and apply to the sputtering target metal tube.

  • Publication number: 20190060205
    Abstract: The present disclosure relates to a networked dispersion of biocellulose microfibrils in water wherein the biocellulose microfibrils have carboxylic groups substituted for alcohol groups, are 30-60 nm in number average diameter with a maximum diameter of 60-100 nm, and are dispersed in an aqueous phase while forming a network. The networked dispersion of biocellulose microfibrils in water according to the present disclosure exhibits excellent skin compatibility and has the effect of allowing the skin to increase in water absorption, elasticity and smoothness. In addition, not only does the networked dispersion of biocellulose microfibrils in water form micro-networks on the skin to prevent microdust from being brought into direct contact with the skin, but also negative charges of the networked dispersion repel those microdust to reduce microdust attachment, so that the present disclosure can be widely utilized in developing a variety of compositions for effectively blocking microdust.

  • Patent number: 9687560
    Abstract: The present invention relates to a skin-permeating peptide, and more particularly, the present invention relates to an isolated peptide capable of permeating the skin to deliver a drug to the skin, to an isolated polynucleotide coding the peptide, to a composition for transdermal delivery comprising the peptide, and to a peptide/cargo composite comprising the peptide and cargo.

  • Publication number: 20160137697
    Abstract: The present invention relates to a fusion protein comprising a skin-penetrating peptide, a polynucleotide encoding the fusion protein, an expression vector comprising the polynucleotide, a transformant comprising the expression vector, a method for preparing the fusion protein, a cosmetic composition for improving skin conditions, which comprises the fusion protein, and a pharmaceutical composition for external skin use, which comprises the fusion protein. The fusion protein of the invention comprises a skin-penetrating peptide bound to a physiologically active protein. The fusion protein significantly enhances the skin penetration and skin retention of the physiologically active protein while maintaining or enhancing the ability of the physiologically active protein to synthesize a material showing physiologically active effects. Thus, it can be widely used as an active ingredient in functional cosmetic compositions and pharmaceutical compositions for external skin use.
