Nanostructured actinide compounds

In Situ Generation of Organic Peroxide to Create a Nanotubular Uranyl Peroxide Phosphate

“…The chair conformation of hexameric uranyl peroxide phosphate macrocycles promotes their stacking through cation–oxo interactions between the hydrated sodium framework and uranyl oxo groups, which results in a one‐dimensional nanotube‐like topology for the extended crystal structure of NUPP . Despite reports of several inorganic uranyl nanotubular structures within the selenite and sulfate systems, NUPP is the first example of one‐dimensional uranyl peroxide structure that has ever been reported in the literature up to date.…”

Further Insight into Uranium and Thorium Metaphosphate Chemistry and the Effect of Nd3+ Incorporation into Uranium(IV) Metaphosphate

“…The chemistry and crystal chemistry of the actinides attracts great interest not only because of their important role in nuclear fuel reprocessing and waste management but also because actinide compounds are most interesting objects for fundamental studies, as they demonstrate great structural diversity and complexity [1][2][3] and even have potentially beneficial properties. [4][5][6][7][8][9] One of the most common uranium minerals, autunite Ca(UO 2 ) 2 (PO 4 ) 2 ·11H 2 O, [10] occurs in the contaminated soils of Fernald Site in Ohio, USA, a former uranium reprocessing plant at which tributyl phosphate was used as an extraction reagent.…”

Carbon nanotubes adsorb U atoms differently in their inner and outer surfaces

“…While, the active chemical properties and distinctive electronic structures of actinide elements have been used to advance nuclear energy and fuel efforts, 1,2 the issue of radioactive waste management still remains a major challenge. 3 Recent advances in nanoscience and nanotechnology related to carbon-based nanomaterials 4,5 have led to promising applications of carbon nanotubes (CNTs) and graphene for waste treatment and extraction of actinide materials.…”
