Abstract: The present invention relates to: a paste composition including ceramic particles surface-functionalized with an amine group and a maleic anhydride-grafted elastomer; and a preparation method therefor and, to: a paste composition enabling ceramic particles to have a high content and be highly dispersed, thereby enabling the composition to have a high generation capacity when a device is manufactured; and a preparation method therefor.

Abstract: An ink composition for photonic sintering and a method or producing the ink composition, the ink composition includes: metal nanoparticles comprising a first metal satisfying interaction formula 1; an organic non-aqueous binder; and a non-aqueous solvent. Interaction formula 1 is A1/A2?0.2, where A1/A2 is a ratio, in the x-ray photoelectron spectrum on the surface of the first metal, in which first metal 2p3/2 peak area of the oxide of the first metal (A1) is divided by first metal 2p3/2 peak area of the first metal (A2).

Abstract: Metal nanoparticles according to the present invention have at least a bimodal size distribution in which the ratio obtained by dividing the area of a first peak, which has the smallest median size on the basis of the median size of peaks in the size distribution of the metal nanoparticles, by the total area of all peaks constituting the size distribution meets 0.4-0.8, and are capped with a capping layer containing an organic acid.

Abstract: This invention relates to a method to induce growth of carbon nanotubes using a liquid phased-hydrocarbon based material under a critical range of equilibrating between liquid and gas phases, thereby easily manipulating a required carbon source. This invention also relates to a method to facilitate easy generation of a carbon backbone of the carbon nanotube because the reaction is performed in the presence of a metal nanoparticle or a metal compound capable of spontaneously generating a seed catalyst which stimulates the growth of carbon nanotubes as well as secures safety enough for the industrial application by using a mild reaction condition within the critical range. Accordingly, this invention can produce the carbon nanotube with high transition efficiency under a mild condition with a relatively lower temperature and pressure than those in conventional gas phased-methods without using a costly equipment, thereby cost-effectively producing the carbon nanotube in large quantities.

Abstract: The present invention relates to novel tin amino-alkoxide complexes and a method for preparing the same, precisely novel tin amino-alkoxide complexes represented by formula 1 and useful as a precursor for tin and tin oxide thin films and a precursor for the production of nano-sized tin and tin oxide particles and a method for preparing the same. In formula 1, A is linear or branched (C2-C10) alkylene substituted or not substituted with halogen; R1 and R2 are independently linear or branched (C1-C7) alkyl substituted or not substituted with halogen.

Abstract: The present invention relates to a carbon nanotube transistor biosensor with aptamers and a method for detecting a target material using the same, more particularly to a carbon nanotube transistor biosensor recognizing the target material, i.e., a specific molecule (such as a protein, a peptide, an amino acid, and an organic/inorganic compound) by using DNA aptamers and a method for screening a target material using the same. In the biosensor of the present invention, the aptamers binding specifically to a particular protein are adsorbed on a carbon nanotube constituting the channel domain of carbon nanotube transistor to easily detect/identify a particular protein via the electric conductivity of carbon nanotube that varies if the particular protein is exposed to corresponding aptamers.
