아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시 10분부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 제목: Nanomaterials Work at NASA-Johnson Space Center 연사: Sivaram Arepalli 교수(에너지과학과) 일시: 2009년 5월 29일(금) 오후4:30 장소: 물리학과 세미나실(31355호실) 초록: Nanomaterials activities at NASA-Johnson Space Center focus on single wall carbon nanotube production, characterization and their potential applications for human space exploration. Nanotubes are produced by arc and laser methods and the growth process is monitored by in-situ diagnostics using time resolved passive emission and laser induced fluorescence of the active species. Parametric study of both these processes are conducted to monitor the effect of production parameters including temperature, buffer gas, flow rate, pressure, laser fluence and arc current [1]. Characterization of the nanotube material is performed using the NASA-JSC protocol developed by combining analytical techniques of SEM, TEM, UV-VIS-NIR absorption, Raman, and TGA [2]. Efforts at JSC over the past five years in composites have centered on structural polymer/nanotube systems. Recent activities broadened this focus to multifunctional materials, supercapacitors, fuel cells, regenerable CO2 absorbers, electromagnetic shielding, radiation dosimetry and thermal management systems of interest for human space flight [3]. Preliminary tests indicate improvement of performance in most of these applications because of the large surface area as well as high conductivity exhibited by single wall carbon nanotubes. 자료를 다운 받으시려면 아래의 링크을 클릭해주세요. http://physics.skku.ac.kr/ppt/090529.pdf
