Of Wholes and Parts: Local History and the American Experience

The relationships between the wholes and parts of American history are vital to our understanding of ourselves as a nation and a people. Many of the central paradoxes and ambiguities of our national existence cannot be adequately understood without exploring the interplay between localism and nationalism that runs like a lietmotiv throughout American history. The influence of the westward movement in our nation’s past, the give and take of federal-state relations, the internecine sectionalism of the nineteenth century, and the more benign regionalism of the twentieth century raise important questions about the relationship between local history and national heritage, and why they sometimes seem antithetical

Recovery of High Specific Activity Molybdenum-99 From Accelerator-Induced Fission on Low-Enriched Uranium for Technetium-99m Generators

A new process was developed to recover high specific activity (no carrier added) 99Mo from electron-accelerator irradiated U3O8 or uranyl sulfate targets. The process leverages a novel solvent extraction scheme to recover Mo using di(2-ethylhexyl) phosphoric acid following uranium and transuranics removal with tri-n-butyl phosphate. An anion-exchange concentration column step provides a final purification, generating pure 99Mo intended for making 99Mo/99mTc generators. The process was demonstrated with irradiated uranium targets resulting in more than 95% 99Mo recovery and without presence of fission products or actinides in the product
