...those mined or produced by MINATOM. These include internationally restricted materials like boron 10, which is used in reactor control rods, and osmium 187, a nonradioactive isotope that can sell for more than $100,000 a gram. International trade in other, less exotic materials, such as zirconium, beryllium and hafnium, is controlled by nuclear nonproliferation agreements...
Isotopes and Hafnium. The work of the chemistry prizewinner, Hevesy, was related to the physicists' researches. He studied atoms by means of X rays and isotopes (slight variations in chemical elements which differ from each other only in radiactivity or atomic weight). By X-ray analysis, Hevesy discovered hafnium, No. 72 in the table of elements...
Professor de Hevesy is the discoverer of the element "hafnium" and introduced the application of isotopes as indicators in chemistry. He was formerly Lecturer in Budapest University and Professor of Physical Chemistry in Freiburg University. He has been at the Copenhagen University Institute since...
...soft silvery-white metal which will look and react much as do the alkali metals lithium, sodium, potassium, rubidium and cesium. When eka-cesium is isolated, then Messrs. Allison & Murphy will have the pleasant problem of naming it. The recent tendency for such names has been after places-hafnium (1922) for Hafnia (Copenhagen), masurium (1924) for the Masurian Lakes, rhenium (1924) for the Rhine, illinium (1926) for Illinois. Hence, for eka-cesium, alabamium is appropriate for the state in which the discoverers work...
...half-ounce morsel to which he had reduced his original 400 pounds of rare earth ores in his search. Scientists hailed him, particularly his countrymen. Though laboratories throughout the world are constantly searching for the remaining unknown elements, no other elemental discovery has been made since Hafnium, No. 72, in 1923, at Copenhagen, by Chemists Coster and Hevesy. And never before has a new element been first discovered in a U. S. laboratory. It may well mean for Dr. Hopkins, they said, the $40,000 Nobel chemistry prize in 1926, an honor won by no other U. S. chemist save...
