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: Disclosed is an aerosol-deposition-coating method for plasma-resistant coating, in which the inside of a processing device can be protected from plasma during a plasma-etching process, the roughness of a coating layer on a metal substrate can be decreased to thereby reduce the generation of particles, and adhesion between the coating layer and the metal substrate can be enhanced.

Abstract: A memory system, a memory controller and an operating method are disclosed. When a target command which instructs an operation of writing target data to a memory device is received from a host, the target data is divided into data units, and a first data unit among the data units is controlled such that the entire first data unit is written to the memory device or none of the first data unit is written to the memory device. As a consequence, it is possible to write data in specific units in a memory system using a multi-core.
