Abstract: Provided is a CNT film coated substrate in which CNT is fixed to a substrate using a click reaction, so that a CNT film is uniformly formed with a high density and adhesive strength between the CNT film and the substrate is excellent to have high stability to water or an organic solvent. In the case of the conventional CNT film which was manufactured by spin coating, most of CNT was peeled off in a washing process, but in the case of the CNT film coated substrate according to the present invention, a high-density uniform CNT film coated substrate may be manufactured even after washing, and reproducibility between substrates may be secured.

Abstract: The present disclosure relates to a method of preparing an anisotropic pitch for carbon fiber, and more particularly, to a method of preparing an anisotropic pitch of preparing a pitch having a low softening point by thermally polymerizing heavy oil or residue oil generated in an oil refining process, extracting only a mesogen component, and then heat-treating at a high temperature for a short time. The anisotropic pitch prepared in the present disclosure has advantages of exhibiting the anisotropic content of 100% and controlling the anisotropic content only a simple temperature control as desired and may be used as a precursor of a high value-added carbon material such as carbon fiber and an anode material for a lithium secondary battery.

Abstract: The present invention relates to an organic-inorganic hybrid nanoporous material, maintaining a nanoporous skeleton structure formed by coordination of an organic ligand containing an aromatic compound to a trivalent central metal ion, and further having an intramolecular acid anhydride functional group modified on the aromatic compound of the nanoporous skeleton structure, and thereby exhibits selectivity for olefins, and an adsorbent comprising the same. Specifically, the organic-inorganic hybrid nanoporous material of the present invention exhibits an excellent olefin-selective adsorption capacity through differences in adsorption equilibrium and adsorption rate, and thus can be usefully employed in the separation of C2-C4 hydrocarbons. Further, the olefins adsorbed to the organic-inorganic hybrid nanoporous material can be desorbed by purging of an inert gas which is not liquefied by way of mild vacuum conditions or compression, and thus, the organic-inorganic hybrid nanoporous material can be used to prepare olefins by separating C2-C4 hydrocarbon mixtures.

Abstract: The present disclosure relates to a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen. The bifunctional catalyst includes a carbon composite including cobalt (Co) and nitrogen (N) atoms forming a coordinate bond with the cobalt, and metal particles which exhibit a catalytic activity for a Fischer-Tropsch synthesis reaction and which are dispersed on the inner pore surface and/or the outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction.

Abstract: A stereotactic device for primate brains indicates a brain coordinate reference point of a primate using a simulator for indicating a brain coordinate reference point, thereby providing an initial setting to a zero point corresponding to the brain coordinate reference point. The brain coordinate reference point is conveniently and accurately indicated without relatively expensive equipment, such as a magnetic resonance imaging (MRI) scanner, to determine brain coordinates of the primate, so that a targeting procedure can be conducted on the brain.
