Nanofiber membranes are described that include multiple layers of nanofiber structures, where each structure is a composite composition of multiwall carbon nanotubes and one or both of single wall and/or few walled carbon nanotubes. By selecting the relative proportions of multiwall and one or more of single/few wall carbon nanotubes in a nanofiber film, the membrane can be fabricated to withstand the heating that occurs during operation in an EUV lithography machine, while also having enough mechanical integrity to withstand pressure changes of between 1 atmosphere (atm) and 2 atm between operating cycles of an EUV lithography machine.

The present invention relates to a carbon nanotube having an La(100) of less than 7.0 nm when measured by XRD and a specific surface area of 100 m.sup.2/g to 196 m.sup.2/g, and an electrode and a secondary battery including the carbon nanotube.

The invention relates to a silicon-based anode material for a lithium-ion battery, a preparation method therefor, and a battery. The silicon-based negative electrode material is prepared by the compounding of 90 wt %-99.9 wt % of a silicon-based material and 0.1 wt %-10 wt % of carbon nanotubes and/or carbon nanofibers which grow on the surface of the silicon-based material in situ.

Carbon nanostructures are used to prepare electrode compositions for lithium ion batteries. In one example, carbon nanostructures, fragments of carbon nanostructures and/or fractured carbon nanotubes are provided in an aqueous dispersion that can be used in the manufacture of silicon-containing anodes. The aqueous dispersion can further include another conductive carbon additive such as carbon black.

It was found that HDT and storage Modulus for so produced reinforced blends were unexpectedly extremely high as compared to PEK/ABPBI blends without MWCNTs.

The present disclosure discloses a catalyst composition comprising: (a) at least one steamed biochar; and (b) at least one tri-metallic catalyst, comprising metals selected from the group consisting of nickel, copper, zinc, and combinations thereof, wherein nickel loading is in the range of 20-60 wt %, the copper loading is in the range of 0.5-5.0 wt %, and the zinc loading is in the range of 0.5-5.0 wt with respect to the at least one steamed biochar.

Methods for making porous nanotube fabrics are disclosed. Within the methods of the present disclosure, a porogen-loaded nanotube application solution is formed by combining a first volume of nanotube elements with a second volume of fuel material in a liquid medium to form a porogen-loaded nanotube application solution. In some aspects of the present disclosure, a third volume of oxidizer material is also combined into the liquid medium. A porogen-loaded nanotube fabric is formed by depositing the porogen-loaded nanotube application solution. In some aspects of the present disclosure, the fuel material within the porogen-loaded nanotube application solution will react with oxidizer material when heat is applied to a sufficient degree and volatize. The off-gassed fuel material will then leave behind voids in the nanotube fabric, rendering the fabric porous.

The present invention relates to a carbon nanotube-transition metal oxide composite and a method for making the composite. The composite comprises at least one carbon nanotube and a plurality of transition metal oxide nanoparticles. The plurality of transition metal oxide nanoparticles are chemically bonded to the at least one carbon nanotube through carbon-oxygen-metal (C—O-M) linkages, wherein the metal is a transition metal element. The method for making the composite comprising the following steps: step 1, providing at least one carbon nanotube obtained from a super-aligned carbon nanotube array; step 2, pre-oxidizing the at least one carbon nanotube; step 3, dispersing the at least one carbon nanotube in a solvent to form a first suspension; step 4, dispersing a material containing transition metal oxyacid radicals in the first suspension to form a second suspension; and step 5, removing the solvent from the second suspension and drying the second suspension.

The embodiments of the present disclosure relate to a method, system and composition producing a magnetic carbon nanomaterial product that may comprise carbon nanotubes (CNTs) at least some of which are magnetic CNTs (mCNTs). The method and apparatus employ carbon dioxide (CO.sub.2) as a reactant in an electrolysis reaction in order to make mCNTs.
