(KR20160129759) The present invention relates to an apparatus for producing artificial skin and a method for producing artificial skin using the apparatus. When using the apparatus for producing artificial skin according to the present invention, artificial skin can be easily produced by simple mechanical stimulation without any other chemical or electrical stimulation. In addition, the artificial skin produced by using the apparatus for producing artificial skin of the present invention has a high penetration level, and thus can be helpfully used in the fields of skin-related cosmetics and development test models for new drugs.

(KR20160129754) The present invention relates to a preparation method of 4-hydroxy-benzoic acid long-chain ester. The preparation method of 4-hydroxy-benzoic acid long-chain ester comprises a step of making 4-hydroxy-benzoic acid short-chain ester react with aliphatic alcohol. Also, the present invention relates to a purification method of 4-hydroxy-benzoic acid long-chain ester comprising the following steps of: adding an aqueous acid solution to a crude composition including 4-hydroxy-benzoic acid long-chain ester; separating the crude composition into an organic phase and an aqueous phase; and extracting the organic phase.

(WO2016181864) Provided is a glass sheet having a predetermined composition. In a sample A collected from the central portion of the glass sheet cut in the direction perpendicular to a first main surface such that the dimensions of the sample are 50 mm vertically × 50 mm horizontally × a thickness θ and the arithmetic average roughness Ra of the two main surfaces and first and second cut surfaces facing each other is 0.1 µm or less, αave1 is 0.009 or less and the ratio of αave2/αave1 is 1.3 or less, where αave1 is the average extinction coefficient of the first main surface at a wavelength of 400-700 nm, as measured in the normal direction of the first main surface, and αave2 is the average extinction coefficient of the first cut surface at a wavelength of 400-700 nm, as measured in the direction perpendicular to the normal direction.
(WO2016181636) The present invention provides a dispersion of inorganic particles which combines excellent dispersion stability with a high viscosity and can be burned at relatively low temperatures. The dispersion of inorganic particles is characterized by including: inorganic particles, at least some of the surface thereof having a C6 or lower short-chain amine; a polymeric dispersant comprising a polymer of a comb-shaped structure that has one or more pigment-philic groups in the main chain and/or a plurality of side chains thereof and has a plurality of side chains each constituting a salvation moiety, or a polymer that has, in the main chain, a plurality of pigment-philic moieties each constituted of a pigment-philic group, or a linear polymer that has, at one terminal of the main chain, a pigment-philic moiety constituted of a pigment-philic group; and a dispersion medium. The dispersion is further characterized in that the dispersion medium contains a protective dispersant having an acid value, the acid value of the protective dispersant being 1-200 and the addition amount of the protective dispersant being 0.1-10 wt% based on the inorganic particles on a solid basis.
