    Abstract: Disclosed are apparatus and method for preparing carbon black, in which the carbon black may be continuously formed and activated. In one embodiment, carbon black powders formed in a combustion reactor are converted into a slurry which in turn is refluxed to the combustion reactor in a repeated manner, thereby to allow successive activation treatments. In this way, a sufficient residence time for the activation of the carbon black may be secured.

    Abstract: A flow frame for a redox flow battery includes: a frame body having a plate-like shape and an electrode hole in its center where an electrode is to be disposed; four through holes disposed at corners of the frame body, respectively; a flow channel disposed at a front of the frame body above and below the electrode hole so that two of the through channels diagonal to each other as a pair are connected to each other via the electrode hole; through channels disposed at distal ends of the flow channel to cause electrolyte flows toward a rear of the frame body; and a distribution channel connecting the through channels with the electrode hole at the rear of the frame body. The flow channel has at least one branch point, and a change in cross sectional area of the flow channel before and after the branch point is 10% or less.

    Abstract: Disclosed are an electrode for electrolytic plating and an electrolytic plating apparatus including the same. A contact area between a surface of an object to be plated and an electrode can be minimized using an electrode for electrolytic plating having a non-conductive pattern partially formed thereon. Generation of a metal composite having multiple cores due to simultaneous contact between plural objects to be plated and the conductive region being not covered with non-conductive pattern can be prevented. Since the surface of the object to be plated can be coated with different kinds of metals before galvanic corrosion occurs, a metal composite having a core-shell structure can have improved reliability, quality and stability. Various different kinds of metals can be coated onto the surface of the object to be plated without limitation as the object to be plated.
