Abstract: Disclosed is a method for producing hydrogen, carbon, and ethylene from a methane-containing feedstock even without recycling of unreacted methane by providing a single process or system in which a methane-containing feedstock is subjected to two methane conversion steps. The method includes a first conversion step of producing hydrogen and carbonaceous materials and a second conversion step of producing acetylene from unreacted methane and hydrogen discharged from the first conversion step while maintaining a good methane conversion and suppressing coke formation, followed by separating and recovering ethylene and hydrogen produced through selective hydrogenation of acetylene.

Abstract: The method includes forming a first dielectric layer on a substrate, forming a via in the first dielectric layer, sequentially forming a first metal pattern, a first metal oxide pattern, a second metal pattern, and an antireflective pattern on the first dielectric layer, and performing an annealing process to react the first metal oxide pattern and the second metal pattern with each other to form a second metal oxide pattern. The forming the second metal oxide pattern includes forming the second metal oxide pattern by a reaction between a metal element of the second metal pattern and an oxygen element of the first metal oxide pattern.

Abstract: The present application relates to a novel strain of the genus Schizochytrium (Schizochytrium sp.) and a method of producing polyunsaturated fatty acids by using the same. According to one aspect, novel microalgae of the genus Schizochytrium have a high content of fat in biomass, and particularly, a high content of polyunsaturated fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and therefore, the microalgae, and biomass or bio-oil prepared therefrom, may be useful as a feed source or the like.
