Abstract: Disclosed is a composition for promoting hair growth and ameliorating, preventing or treating hair loss containing 2?-fucosyllactose (2?-FL) as an active ingredient, and a method for promoting hair growth or ameliorating, preventing or treating hair loss, the method comprising administering to a subject in need thereof 2?-fucosyllactose. Treatment with a combination of testosterone and 2?-fucosyllactose increases hair gloss, increases hair length, reduces a hair loss area, enhances hair cuticles, increases the number and size of hair follicles, and improves expression of proteins and genes related to hair proliferation and growth, compared to treatment with testosterone alone, thus being applicable as a substance for various food and pharmaceutical compositions based on effects of promoting hair growth, improving hair loss, and ameliorating, preventing or treating hair loss.

Abstract: A slurry composition may include an abrasive, a solvent, and polyol. The abrasive may include any one of metal oxide, metal nitride, metal oxynitride, and a combination thereof. The polyol may have about 0.01 mM to about 500 mM of a concentration. Thus, high polishing selectivities may be provided between a B—Si layer, a TiN layer and a SiN layer by controlling a polishing rate of the TIN layer.

Abstract: The present invention relates to an electric vehicle battery pack case, and the purpose of the present invention is to provide an electric vehicle battery pack case which comprises continuous fibers and discontinuous fibers, and thus is lightweight and yet has rigidity.

Abstract: A printed circuit board includes: a substrate layer in which a plurality of insulating layers and a plurality of wiring patterns are repeatedly layered, the substrate layer including a conductive via layer disposed in one of the plurality of insulating layers to connect wiring patterns, among the plurality of wiring patterns, disposed on upper and lower surfaces of the one insulating layer, respectively; an uppermost substrate layer including an outermost insulating layer disposed outermost within the substrate layer, and a first wiring pattern disposed in the outermost insulating layer; and a bump pad disposed on a portion of an upper surface of the first wiring pattern and having a length shorter than a length of the first wiring pattern.

Abstract: There is provided an apparatus for preparing a graphene-structured material. The apparatus includes a supply hopper configured to supply graphite oxide; a supply line of which an end is connected to a lower end of the supply hopper; a reducing atmosphere gas supply unit connected to a side of the supply line; a vertical fluidized bed furnace of which a lower part is connected to another end of the supply line and configured to reduce the supplied graphite oxide with thermal-expansion; a discharge line of which an end is connected to an upper part of the vertical fluidized bed furnace; a vibrating type vertical micro filter connected to an opening portion on a side of the discharge line; a vacuum pump connected to the vertical micro filter; and a collector positioned under the vertical micro filter and connected to another end of the discharge line.

Abstract: There is provided a method and an apparatus for preparing graphite oxide. In accordance with the present disclosure, when an oxidizer is added by stages into a sequencing batch oxidizer mixer connected in multiple stages at a constantly low temperature, the oxidizer is mixed therein while suppressing an oxidation reaction. During an oxidation reaction of graphite, in a risky range of overheating and explosion, a tube type reactor equipped within a heat exchanger is used to accurately control a local temperature and the oxidizer can permeate between layers of the graphite with increased efficiency under ultrasonication. In an additional reaction range out of the risky range, a continuous stirred tank reactor is used to mature the oxidation reaction, so that a risk of explosion during manufacturing of graphite oxide can be reduced and a great amount of graphite oxide can be mass-produced economically.
