아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시 20분부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 제목: Manmade Elements 연사: Vijay.K.Manchanda 교수 (성균관대학교 에너지과학과) 일시: 2009년 11월 13일(금) 오후4:30 장소: 물리학과 세미나실(31355호실) 초록: About one fifth of known elements are manmade. Journey of manmade elements started during the second world war and it was the device of a manmade element which was used to clinch the victory for the allies. In Berkeley, California, a young chemist named Glenn Seaborg synthesized and isolated a new element, Plutonium ,which was instrumental to bring an end to the World War II. Glenn Seaborg went on to discover ten new elements, more than any scientist in history, and synthesized hundreds of radioactive isotopes, with applications in everything from the treatment of cancer, to the common household smoke detector and a major power source for mankind on earth as well as for space / ocean exploration. IUPAC in it’s meeting in China in July, 2009 has accepted Copernicium as the nomenclature for the element 112 which corresponds to the last member of the 6d transition series. “Atom at a time Chemistry” techniques and alpha-alpha correlations with the known daughters have helped in the identification of the new elements , some of which have the half lives of the order of milliseconds. Quest for the synthesis of new elements has reached the inert gas configuration Z=118 and is likely to continue to unravel the fascinating world of nucleus. 자료를 다운 받으시려면 아래의 링크을 클릭해주세요. http://physics.skku.ac.kr/ppt/20091113_Physics Seminar -Manmade elements.pdf
