Publication number: 20170151595Abstract: The present invention relates to a method for manufacturing an ultrafine single-crystalline metal wire. The method continuously manufactures an ultrafine long single-crystalline wire by shaping a grown single-crystalline metal to have a circular or rectangular cross section and then by drawing the shape-processed single-crystalline metal using a drawing machine. Therefore, the method simplifies manufacturing procedures to reduce manufacturing costs and lowers electrical resistance of a produced metal wire to improve the quality of the produced metal wire. The method comprises: a first step of growing a single-crystalline metal ingot using a Czochralski or a Bridgman method; a second step of subjecting the single-crystalline metal ingot to a shaping process such that the single-crystalline metal ingot has a certain shape; and a third step of completing the manufacture of an ultrafine single-crystalline metal wire by drawing the shape-processed single-crystalline metal.Type: ApplicationFiled: March 23, 2015Publication date: June 1, 2017Inventors: Se-young Jeong, Sang-eon Park, Seung-hun Lee, Seung Jeong, Hoon-chul Yang

Publication number: 20150292113Abstract: The present invention relates to a metal single crystal in which a metal element is substituted, wherein a metal element A is doped with a metal element B different from the metal element A to form A1-XBX, and a mixed single crystal is formed therefrom by high temperature melting (wherein the metal element A is any one of silver, copper, platinum and gold; the metal element B is any one of silver, copper, platinum and gold; and 0.01?x?0.09). Therefore, a metal single crystal, which is a mixed crystal with more superior electrical properties than a conventional metal, is formed by doping a metal with excellent electrical properties with a metal element different from the metal, and growing the doped metal into a mixed crystal.Type: ApplicationFiled: September 17, 2013Publication date: October 15, 2015Inventors: Se-young Jeong, Ji-young Kim, Yong-chan Cho, Sang-eon Park, Chae-ryong Cho

Patent number: 8003815Abstract: The present invention provides a method of preparing a cross-condensed compound of an amino-acid derivative and (aminoalkyl)trialkoxysilane using microwave, including: irradiating and heating an amino-acid derivative and (aminoalkyl)trialkoxysilane in a microwave reactor to obtain a reaction product (step 1); and refining the reaction product obtained in the step 1 by removing an unreacted solid material from the reaction product and then leaving the reaction product at room temperature under vacuum to remove excess (aminoalkyl)trialkoxysilane therefrom (step 2). According to the method, since a cross-condensation reaction is performed using microwave, unlike a conventional condensation reaction, economic efficiency is increased due to no catalyst, short reaction time and no solvent. Further, the yield and selectivity of products is increased, and the condensation reaction can be environment-friendly performed because a solvent which can badly influence the environment may not be used.Type: GrantFiled: February 22, 2008Date of Patent: August 23, 2011Assignee: Inha-Industry Partnership InstituteInventors: Ik Mo Lee, Dong Hwan Lee, Ho Sub Kim, Sang Eon Park
