    Abstract: An apparatus for manufacturing a carbon nanostructure and a method for manufacturing a carbon nanostructure that can achieve an increase in length and shape stabilization of the carbon nanostructure can be obtained. A manufacturing apparatus for a carbon nanostructure includes a catalyst member on which a carbon nanostructure is grown, a source gas supply unit and a source gas supply pipe, a coil, and a heater. The source gas supply unit and the source gas supply pipe supply the catalyst member with carbon for forming the carbon nanotube. The coil applies a gradient magnetic field (e.g., a cusped magnetic field indicated by magnetic flux line whose magnetic field strength gradually increases from one surface of the catalyst member to the other surface opposite to the one surface. The heater heats the catalyst member.

  • Publication number: 20130009089
    Abstract: The invention relates to a method for the carbon coating of metallic nanoparticles. The metallic nanoparticles, which are produced using the metal-salt hydrogen-reduction method, can be coated with carbon by adding a hydrocarbon (for example, ethylene, ethane, or acetylene) to the hydrogen using in the synthesis. The carbon layer protects the metallic particles from oxidation, which greatly facilitates the handling and further processing of the particles. By altering the concentration of the hydrocarbon, it is possible, in addition, to influence the size of the metallic particles created, because the coating takes place simultaneously with the creation of the particles, thus stopping the growth process. A carbon coating at most two graphene layers thick behaves like a semiconductor. As a thicker layer, the coating is a conductor. If the hydrocarbon concentration is further increased, a metal-CNT composite material is formed in the process.

    Abstract: This invention utilizes atomic layer deposition (ALD) to deposit a layer of a material (e.g., aluminum oxide) as a passivation and adhesion enhancement layer on a piezoelectric layer and an interdigitated transducer(s) (IDT(s)) of a surface acoustic wave (SAW) filter and also utilizes a photosensitive polymer layer (e.g., epoxy dry film) for photodefining a cavity for SAW filter fabrication. The ALD layer serves to protect the IDTs from possible corrosion caused by either the polymer layer and/or moisture and at same time provide for stable operation of the SAW filter without a signal shift occurring by protection of the piezoelectric layer. The cavity, having walls formed by the photosensitive polymer, provides for a SAW fabrication process that is simple and cost effective.

    Abstract: A plasma treatment has been used to modify the surface of BNNTs. In one example, the surface of the BNNT has been modified using ammonia plasma to include amine functional groups. Amine functionalization allows BNNTs to be soluble in chloroform, which had not been possible previously. Further functionalization of amine-functionalized BNNTs with thiol-terminated organic molecules has also been demonstrated. Gold nanoparticles have been self-assembled at the surface of both amine- and thiol-functionalized boron nitride Nanotubes (BNNTs) in solution. This approach constitutes a basis for the preparation of highly functionalized BNNTs and for their utilization as nanoscale templates for assembly and integration with other nanoscale materials.

  • Patent number: 8236251
    Abstract: Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.

  • Publication number: 20120192931
    Abstract: Disclosed is a carbonaceous nanocomposite including: a substrate; a graphene sheet formed on a top surface of the substrate in parallel with the substrate; and a carbonaceous nanomaterial provided on another surface of the graphene sheet, the nanomaterial having an aspect ratio of 2 to 75,000 to make a predetermined angle with the graphene sheet. The carbonaceous nanocomposite according to the present disclosure has excellent adhesivity to the substrate and can be attached to the substrate without undergoing a pasting process. Since a two-directional current flow is generated, the electrical resistance of the graphene and carbon nanotube is considerably reduced. In addition, the graphene allows the carbon nanotube to have a high current density and a high specific surface area, thereby accelerating a redox reaction. The excellent heat-radiating property of the graphene sheet allows fast transfer of heat generated in the carbon nanotube to outside, thereby avoiding degradation of the carbon nanotube.

  • Publication number: 20120148756
    Abstract: A method of producing compound nanorods and thin films under a controlled growth mode is described. The method involves ablating compound targets using an ultrafast pulsed laser and depositing the ablated materials onto a substrate. When producing compound nanorods, external catalysts such as pre-deposited metal nanoparticles are not involved. Instead, at the beginning of deposition, simply by varying the fluence at the focal spot on the target, a self-formed seed layer can be introduced for nanorods growth. This provides a simple method of producing high purity nanorods and controlling the growth mode. Three growth modes are covered by the present invention, including nanorod growth, thin film growth, and nano-porous film growth.
