Abstract: Disclosed herein is a method of manufacturing a dehydrogenation catalyst, the method includes: forming a functional oxide coating layer on a surface of a support with a first atomic layer deposition; and depositing metal particles on the surface of the support on which the functional oxide coating layer is formed, with a second atomic layer deposition.

Abstract: A tank assembly and a bidet including the same are disclosed. The tank assembly according to one aspect of the present disclosure may include a tank member that is connected to an outside, constitutes an inlet flow path through which a fluid is introduced, and has one side in a height direction open; a cover portion that is connected to an outside, constitutes an outlet flow path of the fluid introduced into an inside, covers the one side of the tank member, and is coupled to the tank member; and an outlet buffer portion that is coupled to the cover portion to constitute the outlet flow path of the fluid together with the cover portion, and is accommodated in the tank member to be located at the one side of the tank member, wherein the outlet buffer portion may include: an outlet buffer space communicated with a cover space formed inside the cover portion; and an outlet buffer communication hole communicating the outlet buffer space with a tank space formed inside the tank member.

Abstract: The present disclosure relates to semiconductor memory devices. An example semiconductor memory device comprises a substrate, a structure including word lines and interlayer insulating films alternately stacked on the substrate, a channel region disposed between two adjacent word lines in a vertical direction, a first source/drain region disposed on a first side of the channel region, a second source/drain region disposed on a second side of the channel region, a bit line which extends in the vertical direction on the substrate and is connected to the first source/drain region, a capping insulating film disposed between the bit line and the word lines, and a data storage connected to the second source/drain region. At least a part of the first source/drain region protrudes from a sidewall of the capping insulating film toward the bit line.

Abstract: The present invention relates to a porous silicon-carbon composite having a core-shell structure, a preparing method therefor, and an anode active material comprising same, wherein the core comprises silicon particles and the shell comprises two or more carbon layers including a first carbon layer and a second carbon layer, so that the application of the composite as an anode active material for a secondary battery can enhance the discharge capacity, initial efficiency, and capacity retention rate of the secondary battery. In addition, the preparing method for the porous silicon-carbon composite having the core-shell structure enables the mass production through a continuous process with minimized steps.

Abstract: Disclosed is the beverage product made of rice and the method for making the same. The method comprises A method of producing a beverage, comprising the steps of roasting the polished and unpolished rice; dividing the rice into particles of reduced size; mixing the rice with refined water; treating the rice with bacteria alpha-amylase whereby gaining a first reaction product; treating the first reaction product with glucoamylase, protease, and pectinase whereby gaining a second reaction product; deactivating the second reaction product; refining the second reaction product; and treating the second reaction product with sucrose fatty acid ester and refined water under uniform pressure of between 130 and 150 bar whereby being emulsified and homogenized.
