Studies on the complexation of actinides
by mono-, di-, and hydroxycarboxylic acids also show a rising trend, mainly for two reasons.
That is because concentrating REEs means concentrating actinides
Microscopic description of octupole shape-phase transitions in light actinide
and rare-earth nuclei.
Table 1 shows my longest elemental words for the 18 groups, counting the lanthanides and actinides
as part of Group 3.
Covering first metal complexes then transition metal chemistry, they discuss such topics as the correct empirical formula of complexes, isomerism and stereochemistry, metal carbonyls and nitrosyls, the vanadium group, and the actinides
The metal actinides
provide radiolytic energy, catalysis for oligomer formation and provide a coordinating ion for metalloenzymes all important in abiogenesis .
For example, monosodium titanate (MST) (1) and sodium nonatitanate (SNT) (2) are amorphous or poorly crystalline materials that are effective ion-exchange materials for the removal of strontium and actinides
Thorium reactors burn waste actinides
, including plutonium generated in uranium reactors, increasing power generation, while at the same time reducing problem waste.
Actinium was the key element in giving the modern periodic table its shape, since Seaborg and his colleagues decided to cleave all the heavy elements known at the time--now called the actinides
, after their first brother--and cordon them off at the bottom of the table.
Giving details of the project, KS Parthasarthy, senior scientist at the Department of Atomic Energy said the AHWR300-LEU Advanced Heavy Water Reactor, produces much less plutonium and minor actinides
compared to Pressurized Water Reactors (PWR) which is the mainstay internationally.
Radioactivity and nuclear processes and properties are generally considered the reserve of physics, but there is a subspecialty of chemistry that incorporates such phenomena as factors in the chemistry of radioactive elements such as the actinides
, radium, and radon and of equipment such as nuclear reactors designed to perform nuclear processes.
plutonium and other actinides
(1) in the spent fuel pose a long-term
2 tonnes fission products and actinides
and 300 kilograms of plutonium, which can then be used to make 60 nuclear weapons
Modelling the binding of Europium and the actinides
by humic substances // Radiochim.
Synergistic solvent extraction of trivalent lanthanides and actinides
by mixtures of 1-phenyl-3-methyl4-benzoyl-5-pyrazolone and neutral oxodonors.
