...England's Cambridge University, provided the theoretical underpinnings of modern solid-state physics in the 1920s. His later work with amorphous materials led to development of the "Mott model," a theoretical framework for understanding the properties of semiconductors made from amorphous materials such as sulfur, selenium and tellurium, all of which are far more economical to produce than crystalline components...
...shot" that stirred up millions of tons of quick-settling coral dust. First radioactive material from the May 21 explosion was brought home by the tuna boat Stiruga Maru. Analyzed by Dr. Kenjiro Kimura of Tokyo University, it proved to contain a familiar array of fission products-ruthenium, rhodium, tellurium, iodine, cerium, neodymium, etc.-as well as uranium 237 and neptunium 239. This combination of elements indicated that the explosion was the "fission-fusion-fission" type, which gets much of its energy from the fission of normally inactive uranium...
Telltale U-237. About 27% of the radiation came from U-237, a short-lived uranium isotope (half-life: 6.75 days) which does not exist in nature. Nearly all the rest came from elements with middle weight atoms, such as tellurium, zirconium and cerium. The content of the sample was roughly the same as that of dust that came from the great U.S. bomb exploded at Bikini on March...
...production hit a new peak with nickel deliveries of 290 million Ibs., while the company also delivered 263 million Ibs. of copper (worth $100 million), 1.637,000 Ibs. of cobalt (worth $4 million), 445,000 oz. of platinum (worth $20 million), plus smaller amounts of gold, silver, selenium and tellurium...
Since the first explosion reverberated through the world's laboratories, the fission of thorium, as well as uranium, has been demonstrated. Atom-wranglers at Columbia University have shown that, under various conditions, the fission of uranium yields krypton, strontium, iodine, xenon, tellurium as disintegration products. The flood of reports made it appear that atomic physicists are off on the biggest big-game hunt since the discovery of artificial radioactivity was announced...
