First known as element 61 in the periodic table ... of californium-252 and plutonium-238 separated from curium and neptunium targets, respectively, that were exposed to intense neutron radiation ...

Heavy element researchers have been keen to lock ... protactinocene from protactinium, neptunocene from neptunium, and plutonocene from plutonium. And in recent years, chemists have even achieved ...

Unlike natural uranium, the reprocessed uranium contained anthropogenic (man-made) radionuclides including the uranium isotope U-236, small amounts of transuranics (elements heavier than uranium, such ...

The radioactive elements in used fuel can be generally ... separations strategies that will extract higher actinides such as neptunium, curium and americium. A robust theory of the electronic ...

Heavy element researchers have been keen to lock down the 15 radioactive ... protactinocene from protactinium, neptunocene from neptunium, and plutonocene from plutonium. And in recent years, chemists ...

These rules help in identifying and writing chemical symbols consistently across all elements. The symbol serves as a shorthand notation for each element's name in formulas and equations ...

Uranium materials with well-defined micro-scale morphologies have diverse applications in the nuclear industry. A key example is their use in high-temperature gas-cooled reactors (HTGRs), where ...

Impact from these research contributions crosses over areas including ‘big science questions’ such as understanding the nature of nuclear matter and nucleosynthesis of the elements formed in stellar ...
