Chemistry in 1951 for "discoveries in the chemistry of transuranium elements". ❋ Unknown (2010)
In attempts to make transuranium elements, i.e., elements with a higher atomic number than 92 (uranium), by radiating uranium atoms with neutrons, Hahn discovered that one of the products was barium, a lighter element. ❋ Unknown (2010)
Ernest O. Lawrence (190158) invented the cyclotron, a device for accelerating atomic particles, which has become the fundamental research tool in high-energy physics and has made possible the creation of transuranium elements. ❋ Unknown (2001)
And then our memories will decay, like the heavier transuranium elements, and we will find ourselves divorced from other people and living in big houses with interlocking pavement stones, room deodorizers, and genuine ten-karat gold faucets. ❋ Coupland, Douglas (1992)
He was co-discoverer of plutonium and all further transuranium elements through element 102. ❋ Unknown (1964)
In addition to the discovery of transuranium elements, Dr. Seaborg and his colleagues are responsible for the identification of more than 100 isotopes of elements throughout the Periodic ❋ Unknown (1964)
The first transuranium element of which there was definite proof was produced by McMillan and Abelson in May 1940 at the University of ❋ Unknown (1964)
The Swedish Academy of Sciences is of the opinion that these discoveries in the realm of the chemistry of the transuranium elements, of which I have here tried to give a brief account, are of such importance that McMillan and Seaborg have together earned the 1951 Nobel Prize for Chemistry. ❋ Unknown (1964)
The Americans were able to investigate this thoroughly, and showed that it forms an isotope of element 93, that is to say, a transuranium element. ❋ Unknown (1964)
Hahn and Strassmann made, however, late in 1938, the epoch-making discovery that is was not really a question of transuranium elements at all here. ❋ Unknown (1964)
Bohr's prophesy that in the transuranium elements we are dealing with a group of substances of the same sort as the rare-earth metals, has thus been confirmed. ❋ Unknown (1964)
The two transuranium elements most recently discovered, berkelium and californium, correspond to terbium and dysprosium in the lanthanides. ❋ Unknown (1964)
Research into the reactions thus produced has, however, met with certain difficulties, and it took longer than was expected for the existence of the transuranium elements to be proved. ❋ Unknown (1964)
By analogy with the way in which names had been found for neptunium and uranium, this second transuranium element was called plutonium, after the planet Pluto, which has its orbit next outside that of Neptune. ❋ Unknown (1964)
Seaborg, as leader of a comprehensive group of able colleagues, completed the studies of the transuranium elements. ❋ Unknown (1964)
By irradiating different sorts of heavy atoms with neutrons, protons, deuterons, helium nuclei, or, most recently, carbon nuclei, a great number of isotopes have been produced from the six transuranium elements. ❋ Unknown (1964)
Not less than four more transuranium elements have been produced. ❋ Unknown (1964)
Otto Hahn and Lise Meitner believed they could confirm Fermi's statement that the transuranium elements are formed by irradiating the heaviest elements with neutrons. ❋ Unknown (1964)
In there the uranium will be ARV UNDER SUSPICION 115 bombarded with neutrons and changed into the various transuranium elements. ❋ Sklar, Richard (1954)
"This is one of the transuranium elements which has never been discovered!" he announced. ❋ Dougherty, William (1954)
