    摘要： The present invention relates generally to reinforced carbon nanotubes, and more particularly to reinforced carbon nanotubes having a plurality of microparticulate carbide or oxide materials formed substantially on the surface of such reinforced carbon nanotubes composite materials. In particular, the present invention provides reinforced carbon nanotubes (CNTs) having a plurality of boron carbide nanolumps formed substantially on a surface of the reinforced CNTs to reinforce the CNTs, enabling their use as effective reinforcing fillers for matrix materials to give high-strength composites. The present invention also provides methods for producing carbide reinforced CNTs.

    摘要： An “outboard pontoon” semisubmersible floating platform for the use of offshore applications has a hull configuration including vertical deck support columns and a horizontally disposed pontoon structure. The vertical columns support the deck structure at upper ends and adjoin pontoon at their lower ends. Under the premise of ensuring platform stability, structural feasibility, and structural cost efficiency, the pontoon is horizontally extrapolated as far as possible radially outward from platform center in the horizontal plan while the elevation of the bottom of columns ranges anywhere from the pontoon bottom to the top surface of the pontoon. The vertical columns are adjoined to the pontoon from its inner periphery and the central vertical axis of each column resides a distance inward from the closest point of the center line of the pontoon. This arrangement makes part of pontoon become the “outboard pontoon” which is the important concept introduced by this invention. The “outboard pontoon” and the raised bottom elevation of the vertical columns will play an important role to reduce the vertical motion response of the platform to the sea waves, which has solid theoretical basis in hydrodynamics. Risers can be supported on the pontoon and columns, be extended to the deck, and the structure can be anchored by mooring lines extending along the outboard face of the outboard columns extending radially outward and downward from their lower ends.

    摘要： Methods and devices to synthesize vertically aligned carbon nanotube (VACNT) arrays directly on a catalytic conductive substrate without addition of an external metallic catalyst layer and without any pretreatment to the substrate surface using a plasma enhanced chemical vapor deposition (PECVD) method are provided. A method comprises providing a catalytic conductive substrate, that has not been pretreated through a plasma enhanced chemical vapor deposition (PECVD) method or other methods, to a PECVD device, etching the catalytic conductive substrate to form catalytically active nano-features on the surface of the catalytic conductive substrate, and growing vertically aligned carbon nanotubes on the surface of the catalytic conductive substrate, without an external metallic catalyst layer, by providing a carbon source gas to the catalytic conductive substrate.
