Abstract: Disclosed herein is a power converter for integrated control of electric oil pumps, which includes a power conversion module configured to receive a direct current voltage to convert the same into an alternating current voltage and to output the converted alternating current voltage to a drive motor, and a control unit configured to control the power conversion module and to control actuation of an oil pump for generating hydraulic pressure in a transmission. The control unit includes a control board, a main controller installed in a partial region of the control board to supply power to the drive motor and to control the power conversion module, and an oil pump controller installed in a remaining region other than the partial region, connected to the main controller, and configured to supply power to a pump motor for actuating the oil pump and to control the oil pump.

Abstract: A synthesis method of a metal catalyst having carbon shell, includes: a) forming a metal-ligand complex without further chemical additives by mixing a ligand with a metal precursor; b) separating the metal-ligand complex and collecting the separated metal-ligand complex; c) supporting the collected metal-ligand complex to a support by mixing the collected metal-ligand complex with the support in a solvent; and d) treating a composite consisting of the metal-ligand complex and the support by heating.

Abstract: A micro reforming reactor includes a first substrate with a micro channel having a width of less than 1,000 ?m bonded to a second substrate to form a micro tunnel. An adhesive layer is formed on the internal walls of the micro tunnel using a flow coating method. A catalyst may then be optionally formed on the adhesive coated internal walls of the micro tunnel, also using a flow coating method.

Abstract: A device comprises a multi-layered thin film having excellent adhesion due to the method of fabricating the same. More particularly, the device includes a multi-layered thin film consisting of a tantalum nitride layer, a tantalum layer formed on the tantalum nitride layer, and a gold thin film formed on the tantalum layer.

Abstract: There is provided a reformer for a fuel cell system, the reformer comprising: a reforming unit having a reaction substrate in which a catalyst layer is formed in a plurality of flow channels for allowing fuel to flow and for generating hydrogen through a reformation reaction of the fuel using thermal energy. When viewing a cross-section perpendicular to the flow direction of the flow channels, the reaction substrate defines each flow channel by a bottom portion and a pair of wall portions extending from the sides of the bottom portion, and a joint between the bottom portion and the wall portion is formed in a rounded shape.
