Disclosed is high conversion and high carbon yielding CARGEN catalyst and a method of preparing the same. The catalyst comprises transition metals that may be supported or unsupported. The preparation method involves mixing a metal material with or without a support in a standard ball milling apparatus to produce a fine and homogenous solid mixture of the transition metal oxide and support. The catalyst is used in the CARGEN system.

Provided is an electrode mixture containing a lithium-containing transition metal oxide; a conductive additive; a binder; and an organic solvent, wherein the conductive additive comprises at least one nanocarbon material selected from the group consisting of a multilayer carbon nanotube, a carbon nanohorn, a carbon nanofiber, a fullerene, and a graphene, the binder comprises a fluorine-containing copolymer comprising vinylidene fluoride unit and a fluorinated monomer unit, provided that vinylidene fluoride unit is excluded from the fluorinated monomer unit, and a content of vinylidene fluoride unit in the fluorine-containing copolymer is more than 50 mol % and 99 mol % or less with respect to all monomer units.

Disclosed are a multi-wall carbon nanotube (MWCNT) formed using arc discharge and a method for manufacturing the same. The carbon source of the anode and boron that is the doping source, are evaporated through arc discharge and then deposited on the surface of the cathode to form MWCNTs, and boron is evenly distributed in the multi-walls of the MWCNTs. Therefore, the outer diameter of the MWCNT is reduced, high thermal stability is secured, and the effect of improving the field emission characteristics can be obtained.

A carbon nanotube dispersion liquid contains a carbon nanotube-containing composition, a dispersant with a weight-average molecular weight of 1,000 to 400,000, a volatile salt, and an aqueous solvent. The carbon nanotube dispersion liquid can maintain a high dispersion of carbon nanotubes even with a smaller amount of dispersant than conventionally used.

The present invention relates to elastomer compositions comprising adducts between compounds of formula (I) preferably derived from natural sources such as mucic, pyromucic, glucaric, glycaric, galactaric, muconic acid and/or linear derivatives thereof containing ester or amide groups and/or cyclic derivatives thereof with heteroatoms in the ring, such as oxygen or nitrogen, and carbon allotropes in which the carbon is sp.sup.2 hybridized, such as for example carbon nanotubes, graphene or nanographites, carbon black.

Polymers suitable for forming carbon nanotube-functionalized reverse thermal gel compositions, compositions including the polymers, and methods of forming and using the polymers and compositions are disclosed. The compositions have reverse thermal gelling properties and transform from a liquid/solution to a gel—e.g., near or below body temperature. The polymers and compositions can be injected into or proximate an area in need of treatment.

A method of manufacturing a paste according to various embodiments of the present disclosure for resolving the above-described problems is disclosed. The method of manufacturing a paste may include an operation of adding a metal conductor and a multi-walled carbon nanotube (MWCNT) to chloroform (CHCl.sub.3) to produce a first mixture, an operation of adding polydimethylsiloxane (PDMS) to the first mixture to produce a second mixture, an operation of evaporating the chloroform in the second mixture to acquire a third mixture, and an operation of adding an additional additive to the third mixture to produce a paste.

A fabric of nanofibers that includes an adhesive is described. The nanofibers can be twisted or both twisted and coiled prior to formation into a fabric. The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

Provided is a catalyst for manufacturing multi-wall carbon nanotubes, the catalyst including metal components according to <Equation> Ma:Mb=x:y, and having a hollow structure with a thickness of 0.5-10 μm. In the above equation, Ma represents at least two metals selected from Fe, Ni, Co, Mn, Cr, Mo, V, W, Sn, and Cu; Mb represents at least one metal selected from Mg, Al, Si, and Zr; x and y each represent the molar ratio of Ma and Mb; and x+y=10, 2.0≤x≤7.5, and 2.5≤y≤8.0.

The device includes, for example, a module for depositing catalyst on a substrate, a module for forming CNTs, a module for separating CNTs from the substrate, a module for collecting the CNTs and a module for continuously and sequentially advancing the substrate through the above modules. The method includes, for example, the steps of depositing catalyst on a moving substrate, forming carbon nanotubes on the substrate, separating carbon nanotubes from the substrate and collecting the carbon nanotubes from the surface, where the substrate moves sequentially through the depositing, forming, separating and collecting steps.
