Separation of Plutonium Oxide Nanoparticles and Colloids

摘要

Current interest in the chemical and physical properties of nanoparticles and chemical nanostructures cannot be overstated. Significant research has been conducted on transition-metal and main-group based nanoparticles. Of interest are their properties and applications in materials synthesis, electronic devices, drug delivery and their role as either environmental contaminants or reagents for remediation. Less exploration has occurred within nanomaterials and colloid phases of the actinide elements, the most studied of which is plutonium. In the report on this subject by Neck et al. Pu~(IV) colloids were shown to play a central role in the thermodynamic modeling of aqueous Pu speciation and redox chemistry.
