摘要： A reinforcement for increasing the strength and toughness and other properties in both transverse and in-piano directions for a composite material, and methods of manufacture therefor. The reinforcement has a layer of a nanoforest of vertical nanotubes or nanowires and a layer of horizontal nanotubes or nanowires. The reinforcement can be made by rolling a vertical nanoforest to produce a collapsed layer of horizontal nanofubes or nanowires, then growing a vertical nanoforest on the collapsed layer. The reinforcement can be grown directly on fibers which are used to reinforce the composite material, or alternatively Interleaved with layers of those fibers before the composite part is cured. The reinforcement and manufacturing method are compatible with almost any composite material in any shape, including epoxy, polymer, or ceramic matrix composites, or any manufacturing method, including prepreg, wet-layup and matrix film stacking. The present invention reduces scrap, rework, and repair hours for composites manufacturing.

摘要： A method is provided for inputting thermal energy into fluidic medium in a high-temperature material production process by at least one rotary apparatus comprising a casing with at least one inlet and at least one exit, a rotor comprising at least one row of rotor blades arranged over a circumference of a rotor hub mounted onto a rotor shaft, and a stator configured as an assembly of stationary vanes arranged at least upstream of the at least one row of rotor blades. In the method, an amount of thermal energy is imparted to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the exit by virtue of a series of energy transformations occurring when said stream of fluidic medium passes through the stationary vanes and the at least one row of rotor blades, respectively. The method further comprises: integration of said at least one rotary apparatus into a high-temperature material production facility configured to carry out high-temperature material production, such as the production of glass, glass wool, carbon fibers, carbon nanotubes, and clay-based materials at temperatures essentially equal to or exceeding 500 degrees Celsius (° C.), and conducting an amount of input energy into the at least one rotary apparatus integrated into the heat-consuming process facility, the input energy comprises electrical energy. A rotary apparatus and related uses are further provided.

摘要： A system and process for producing doped carbon nanomaterials is disclosed. A carbonate electrolyte including a doping component is provided during the electrolysis between an anode and a cathode immersed in carbonate electrolyte contained in a cell. The carbonate electrolyte is heated to a molten state. An electrical current is applied to the anode, and cathode, to the molten carbonate electrolyte disposed between the anode and cathode. A morphology element maximizes carbon nanotubes, versus graphene versus carbon nano-onion versus hollow carbon nano-sphere nanomaterial product. The resulting carbon nanomaterial growth is collected from the cathode of the cell.

摘要： Mineralization occurs during weathering of silicate materials/rocks rich in CA+ and Mg+, particularly peridotite which composes Earth's upper mantle. The carbon mineralization mantle peridotite is the base activated carbon for nanostructured-carbon-base-material. The nanostructured-carbon-base-material using mantle peridotite carbon mineralization based activated carbon nanotubes is a new catalyst for batteries and fuel-cell use that doesn't use precious metal such as platinum and that performs as effectively as many well-known, expensive precious-metal catalysts. The nanostructured-carbon-base-material using mantle peridotite carbon mineralization based activated carbon nanotubes makes possible the creation of economical lithium-air batteries that could power electric vehicles. The carbon nanotubes have useful qualities such as slim, strong, lightweight, high electronic conductivity, has metallic/semiconductive properties that are useful in (1) electronics i.e. wiring, transistor; (2) material that reinforced resin/metal; (3) energy source i.e. catalysis support, ion adsorption, capacitors; (4) nanotechnology i.e. nanostructure; and (5) biotechnology i.e. cell cultivating, drug delivery system, biosensor.

摘要： High-surface area carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls are claimed. Such carbon nanotubes can have little to no inner tube surface oxidation, or differing amounts and/or types of oxidation between the tubes' inner and outer surfaces. Additionally, such high-surface area carbon nanotubes may have greater lengths and diameters, creating useful mechanical, electrical, and thermal properties.

摘要： A CNT production apparatus 1 provided by the present invention includes a cylindrical chamber 10 and a control valve 60 provided to a gas discharge pipe 50. The chamber 10 includes a reaction zone provided in a partial range of the chamber 10 in the direction of the cylinder axis, a deposition zone 22 which is provided downstream of the reaction zone 20, and a deposition state detector 40 that detects a physical property value indicating a deposition state of carbon nanotubes in the deposition zone 22. The apparatus is configured to close the control valve 60 and deposit carbon nanotubes in the deposition zone 22 when the physical property value detected by the deposition state detector 40 is equal to or less than a predetermined threshold value, and configured to open the control valve 60 and recover the carbon nanotubes deposited in the deposition zone 22 when the physical property value exceeds the predetermined threshold value.
