Carlo Perrier (born July 7, 1886, in Turin, † May 22, 1948 in Genoa ) was an Italian mineralogist and chemist who did extensive research on the element technetium. With the discovery of technetium in 1937, he and Emilio Segrè accounted for the last gap in the periodic table.
…(1937) by the Italian mineralogist Carlo Perrier and the Italian-born American physicist Emilio Segrè in a sample of molybdenum that had been bombarded by deuterons in the Berkeley (California) cyclotron.
Feb 28, 2019 · The technetium (from τεχνητός in Greek - technetium in Latin, meaning artificial) is the first artificial chemical element to be isolated by man. This was first achieved by Emilio Segrè (1905-1989) and Carlo Perrier (1886-1948) at the Istituto di Fisica, now Department of Physics and Chemistry, at the University of Palermo ...
Jan 28, 2019 · Enlisting the help of his colleague Carlo Perrier, Segrè carried out a chemical analysis of the plate, extracting an unknown element by boiling a sample with sodium hydroxide and hydrogen...
He found the equipment there primitive and the library bereft of modern physics literature, but his colleagues at Palermo included the mathematicians Michele Cipolla and Michele De Franchis, the mineralogist Carlo Perrier and the botanist Luigi Montemartini . [17]
Segrè enlisted his experienced chemist colleague Carlo Perrier to attempt to prove through comparative chemistry that the molybdenum activity was indeed Z = 43, an element not existent in nature because of its instability against nuclear decay.
Later he was interested in radiochemistry and discovered together with Professor Perrier the element technetium, together with Corson and Mackenzie the element astatine, and together with Kennedy, Seaborg, and Wahl, plutonium-239 and its fission properties.
