Structural characterization of U(VI) in apatite by X-ray absorption spectroscopy.
TLDR
Results indicate that significant amounts of U(VI) can be accommodated in the apatite structure but with an unexpected coordination, which may bear on the ultimate development of apatites-hosted nuclear-waste forms.
Solubilization of plutonium hydrous oxide by iron-reducing bacteria.
TLDR
Observations suggest a potentially attractive, environmentally benign strategy for the remediation of Pu-contaminated soils: iron-reducing bacteria may also reduce and solubilize plutonium.
MULTINUCLEAR NMR, RAMAN, EXAFS, AND X-RAY-DIFFRACTION STUDIES OF URANYL CARBONATE COMPLEXES IN NEAR-NEUTRAL AQUEOUS-SOLUTION - X-RAY STRUCTURE OF C(NH2)(3) (6) (UO2)(3)(CO3)(6) CENTER-DOT-6.5H(2)O
C-13 and O-17 NMR and Raman spectroscopies were used to monitor the fractions of UO2(CO3)(3)(4-) (1) and (UO2)(3)(CO3)(6)(6-) (2) in aqueous carbonate solutions as a function of pH, ionic strength,
A Raman spectroscopic study of arsenite and thioarsenite species in aqueous solution at 25°C
The Raman spectra of thioarsenite and arsenite species in aqueous solution were obtained at room temperature. Solutions at constant ΣAs + ΣS of 0.1 and 0.5 mol kg-1 were prepared with various ΣS/ΣAs
Speciation of Uranium in Fernald Soils by Molecular Spectroscopic Methods: Characterization of Untreated Soils
A combination of X-ray absorption, optical luminescence, and Raman vibrational spectroscopies along with ancillarytechniques such as energy dispersive scanning electron microscopy and powder X-ray
Neptunium and Plutonium Solubilities in a Yucca Mountain Groundwater
Solubilities of neptunium and plutonium were studied in J-13 groundwater (ionic strength of about 3.7 mmol; total dissolved carbonate of 2.8 mmol) from the proposed Yucca Mountain Nuclear Waste
