TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The heating block comprises cement. The flux is a carbon vapor and the deposited material is graphene. Preferred Method: The steps of depositing the flux and collecting the deposited material are performed simultaneously. The method further comprises rotating the heated substrate during depositing and collecting.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The flux stream comprises a carbon vapor and the deposited on the substrate material comprises graphene. The device further comprises: heating element (52) embedded in a heating block, where the heating element imparts heat to the heating block, and the heating block disperse the heat from the heating element throughout the heating block to the substrate; and anode (10) electrode and a cathode electrode, where the anode electrode and cathode electrode are configured to provide the flux stream. The heating block is cylindrical and the substrate is a tube coaxially arranged about the cylindrical heating block. The substrate includes a conical top connected to the rotation device. The substrate and the heating block each has a cylindrical shape and the cylindrical heating block is concentrically arranged inside the cylindrical substrate, where an inside diameter of the cylindrical substrate is greater than an outer diameter of the cylindrical heating block. The substrate is a tube with at least one open end, and the heating block received in the open end of the substrate. The collection device comprises a brush. The flux stream is deposited on the rotating substrate at a first side of the substrate simultaneously with the collection device removing the deposited material from a second side of the rotating substrate, where the first side is different from the second side. The first side comprises a top portion of the substrate and the second side comprises a bottom portion of the substrate. The substrate is cylindrical and has a longitudinal axis that is substantially horizontal.
