Uncovering Heavy Actinide Covalency: Implications for Minor Actinide Partitioning
Inorganic Chemistry, 2019Across the actinide period, the stability of the trivalent oxidation state predominates in the heavy actinides, making their chemical nature close to that of rare earth elements. The resemblance in their chemistry poses difficulties in separating heavy actinides from lanthanides, which is a vital separation in the minor actinide partitioning process ...

An advanced process has been developed on a laboratory scale at the Institute for Transuranium Elements (ITU) for the fabrication of transmutation fuels and targets. The process consists of the fabrication of highly porous beads using a sol–gel method, their infiltration by a nitrate solution of the relevant actinide, and calcination, compaction, and ...

On the aromaticity of actinide compounds
Nature Reviews ChemistryThe chemistry of actinides has flourished since the late 2010s with the synthesis of new actinide complexes and clusters. On the theoretical side, a range of tools is available for the characterization of these heavy element-containing compounds, but discrepancies in the assessment of aromaticity using different tools have led to controversies. In this

There are growing indications that life began in a radioactive beach environment. A geologic framework for the origin or support of life in a Hadean heavy mineral placer beach has been developed, based on the unique chemical properties of the lower-electronic actinides, which act as nuclear fissile and fertile fuels, radiolytic energy sources, oligomer

There exist only two actinides which have long lifetimes and that have been mined and refined in large amounts: thorium and uranium. This chapter discusses them, their uses, and the possibility of their recycling. Furthermore, this chapter examines the other actinides, some of which have uses in only very small quantities, such as americium.

ACTINIDE(VI) AND ACTINIDE (IV) EXTRACTION BY MALONAMIDES
2023This research work aims to study the extractive properties of malonamides for the extraction of uranium(VI) and plutonium(IV) from nitric aqueous phases, and their separation without the use of redox chemistry as in the case of current PUREX process. Malonamides have been widely studied for the separation of minor actinides, however, these molecules ...
