McMillan and Glenn T. Seaborg shared the prize for their discoveries in the chemistry of elements that are heavier than uranium. McMillan discovered the first, neptunium, and developed the synchrotron, the type of particle accelerator used in the discovery of 19 others. Seaborg was co-discoverer of plutonium and nine other transuranium elements.
Name. The surname Glenn is derived from the Irish name gleann.In the 19th century, Glenn also became common as a given name in English speaking cultures. In Sweden, Glenn is relatively common first name in the western parts of the country but especially Gothenburg, originally due to a large and influential population of emigrated Scotsmen, especially in the city's early centuries.
History Discovery. In 1938, Emilio Segrè and Glenn T. Seaborg isolated for the first time the metastable isotope technetium-99m, after bombarding natural molybdenum with 8 MeV deuterons in the 37-inch (940 mm) cyclotron of Ernest Orlando Lawrence's Radiation laboratory.
Les prix Nobel sont des prix décernés chaque année, sauf exceptions, à des personnes, ou à des organismes (prix Nobel de la paix), sous l'autorité de la Fondation Nobel par l'Académie royale des sciences de Suède (physique et chimie), l'Académie suédoise (littérature), l'Institut Karolinska (physiologie ou médecine) et le comité Nobel norvégien du parlement (paix).
1940 plutonium (Glenn T. Seaborg, Arthur C. Wahl, Joseph W. Kennedy ja Segrè) 1944 curium ja amerikium (Seaborg) 1945 prometium (Jacob A. Marinsky) 1949 berkelium (Albert Ghiorso, Seaborg, Stanley G. Thompson ja Kenneth Street Jr.) 1950 kalifornium (Ghiorso, Seaborg, Thompson ja Street)
But Seaborg wanted to know what they were like chemically. To judge from where they seemed to sit in the periodic table, the elements after number 89, actinium, should behave like transition metals. But Seaborg found that they didn't really do that, and in 1945 he suggested that they formed an entirely new series which he called the actinides.
Texas A&M University Regents Professor of Chemistry and Cyclotron Institute Director Dr. Sherry J. Yennello was presented with the Glenn T. Seaborg Award for Nuclear Chemistry award, in conjunction with the ACS 2021 Meeting, on August 22 in Atlanta, Georgia.
