The archaea are actinide
dependent and use cholesterol as an energy substrate.
X-ray Absorption Fine Structure (XAFS) spectroscopy revealed that strontium and the actinides
are bound to the titanate octahedra via inner sphere coordination through the oxygen atoms of the titanate.
Separations chemistry for actinide
elements: recent developments and historical perspective.
Another option is that of partitioning and the transmutation of the long-lived actinides
, americium, curium and neptunium.
The workshop concluded that the potential of current fusion technology to utilize the actinides
for generating energy and destroying long-lived fission products calls for a greater international effort in the area of fusion driven sub-critical systems
The mechanical seal allows minimal internal contamination during adsorption/retardation flow experiments using heavy metals, lanthanides, and actinides
The Integral Fast Reactor's fuel cycle is the first one capable of taking actinides
such as neptunium, americium, and plutonium and automatically putting them back--integrating them quickly and automatically--into the nuclear fuel stream.
The Laboratory of Analytical isotopic and elemental nuclear development (LANIE) wants to be equipped with a thermal ionization mass spectrometer (TIMS) nuclearisable to analyze radioactive samples and especially of actinides
and porphyrins modulate RNA folding and catalyse its ribozymal action.
The areas covered are actinides
and nuclear energy; actinide
physics and metallurgy; experimental instruments for actinide
science; structural materials; ion-solid interactions and swift heavy ions; surfaces, interfaces, and nanomaterials,; nuclear cells; radiation effects; and theory, modeling, and simulation.
Even complete fissioning of all actinides
- an unrealistic proposition - will leave behind large amounts of very long-lived fission and activation products like iodine-129, cesium-135, and chlorine-36 that will pose risks far into the future -- much beyond the 24,100-year half-life of plutonium-239.
Topics include extracting radioactive elements by calixarenes, the simultaneous removal of radionuclides by extractant mixtures, the radiolysis of solvents used in nuclear fuel reprocessing, automating extraction chromagraphic and ion-exchange separations for radiochemical analysis and monitoring, and neoteric solvents as the basis for alternative approaches to separating actinides
and fission products.
