Abstract: The present invention relates to a human induced pluripotent stem cell line transformed with fluorescent protein-tagged CYP1A1 and an AHR modulator screening method using the same. Specifically, a human-induced pluripotent stem cell line (hiPSC line) in which a gene was edited to express a cytochrome P450 1A1 (CYP1A1) protein in a state of fusion with a fluorescent protein without inhibiting its unique function was prepared, and it was confirmed that an AHR modulator could be screened by screening cells in a living state using the cell line-derived liver cells better than in the case of using existing human primary hepatocytes (hPH) or HepG2 cells. Therefore, the CYP1A1-mCherry hiPSC cell line of the present invention can be effectively used for screening AHR modulating compounds.

Abstract: The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.

Abstract: Disclosed are a holographic writing method and apparatus capable of re-writing (updating) holographic information and quickly writing the holographic information with high efficiency. In an embodiment, a holographic writing method for writing holographic information by emitting a beam at a holographic recording medium containing a photo-responsable polymer material having photoisomerization characteristics that change a molecular structure thereof by absorbing light energy, writes the holographic information by using a writing wavelength different from a maximum absorption wavelength in a light absorption spectrum of photoisomer molecule structures of the holographic recording medium. The maximum absorption wavelength is a wavelength at which light absorption rate is maximum in the light absorption spectrum. A difference between the light absorption rates of the photoisomer molecule structures at the writing wavelength is less than a difference between the light absorption rates of the photoisomer molecule structures at the maximum absorption wavelength.

Abstract: Proposed is a high-yield simultaneous conversion method for a hydrogen source and a carbon dioxide source. The method significantly increases a yield of a formate through conversion of carbon dioxide. To this end, a carbon dioxide source and a hydrocarbon containing one or more hydroxy groups undergo a simultaneous conversion reaction in the presence of a solvent containing one or more alcohols and having a pH of 10 to 14.
