TL;DR: In the last decade scientists have dramatically increased their understanding of the chemistry of actinide elements with a potent emphasis on relevance to the environment as discussed by the authors, and this flourishing chemistry of the 5f elements was stimulated by many factors, including inorganic chemists' interest in structural diversity, new synthetic methods, new chemical separations, and a need to understand the fate and transport properties of the actinides in natural aquifer systems.

TL;DR: It is demonstrated that Cr accumulation in unsaturated biofilms occurs with enzymatic reduction of Cr, cellular lysis, cellular association, and extracellular DNA binding of Cr(III), which altogether can facilitate localized biotic stabilization of Cr in contaminated vadose zones.

TL;DR: In this article, C-13 and O-17 NMR and Raman spectroscopies were used to monitor the fractions of UO2(CO3)(3)(4-) + 3H(+) reversible arrow in aqueous carbonate solutions as a function of pH, ionic strength, carbonate concentration, and temperature.

TL;DR: The DFT calculations for the model systems correlate well with experimentally determined metrical parameters, and indicate that the enhanced covalency in the M-E bond as group 16 is descended arises mostly from increased metal d-orbital participation.

TL;DR: In this article, a new chemistry of selenium analogues of dithiophosphinate actinide extractants is reported, which are synthesized, structurally and spectroscopically characterized, and quantum calculations performed on model compounds in which the phenyl rings have been replaced by methyl groups.
