Abstract: The present invention relates to an insulating gas used for electrical insulation or arc extinguishing of an electrical device, and an electrical device for insulating electricity using the same. The insulating gas of the present invention, which may replace SF6 gas, consists of a mixed gas of trifluoromethyl trifluorovinyl ether (CF3OCFCF2) and a carrier gas. The insulating gas of the present invention has the characteristics of a low boiling point, high dielectric strength, low toxicity, and a low global warming potential (GWP=1 or less), and thus may replace SF6, and the low global warming potential with no loss of high insulating capacity and arc extinguishing capability may reduce greenhouse gases.

Abstract: One embodiment of the present invention provides a method of manufacturing an electronic device using a cyclic doping process including i) an operation of forming a unit transfer thin film including a two-dimensional material on a transfer substrate, ii) an operation of doping the unit transfer thin film in a low-damage doping process, iii) an operation of transferring the unit transfer thin film doped according to the operation ii) on a transfer target substrate, and iv) an operation of repeatedly performing the operations i) to iii) several times to reach a target thickness.

Abstract: Disclosed is a inlaid type floor sheet having polyvinyl chloride chip and a method of manufacturing thereof. The in-laid type floor sheet having polyvinyl chloride (PVC) chip, includes an inlaid chip layer in which polyvinyl chloride is formed into chips; a UV paint layer which is coated on the inlaid chip layer; and a dimensionally reinforcing layer which is formed of a fabric and pressed on a lower surface of the inlaid chip layer at high temperature. According to the present invention, since the plain weave type dimensionally reinforcing layer is provided at the lower side of the inlaid type floor sheet having polyvinyl chloride chip, it is possible to improve the durability, realize the dimensional stability and balance of the product and increase the adhesive force with the construction floor.
