Magnesium-zinc reduction is effective in preparation of metals [PDF]

open access: yes, 1967
Uranium, thorium, and plutonium are effectively prepared by magnesium-zinc reduction, using uranium oxides, thorium dioxide, and plutonium dioxide as starting materials.

Low radon exposures and lung cancer risk: joint analysis of the Czech, French, and Beaverlodge cohorts of uranium miners. [PDF]

open access: yes, 2019
It is well established that high radon exposures increase the risk of lung cancer mortality. The effects of low occupational exposures and the factors that confound and modify this risk are not clear and are needed to inform current radiation protection ...

Enhanced Thermodynamic Stability of UO22+ Complex Through Structure Preorganization of N3O2‐Pentadentate Planar Ligand for Uranium Harvesting from Seawater

open access: yesAdvanced Science, EarlyView.
Thanks to the appropriate structure preorganization of an N3O2‐pentadentate planar ligand, 2,6‐bis(2‐hydroxyphenylmethylaminomethyl)pyridine (H2saldamp) exhibits the strongest coordination affinity to UO22+ (log βU = 33.60) compared to ligands developed for uranium harvesting from seawater to date, as well as good separability of UO22+ from other metal

Evaluation of uranium migration during the maturation of hydrocarbon source rocks

open access: yesScientific Reports
The source of uranium is an important research topic related to the exploration of sandstone-type uranium deposits, and potential uranium sources in deep basins are often overlooked.

Ab initio modeling of oxygen impurity atom incorporation into uranium mononitride surface and subsurface vacancies

open access: yes, 2012
The incorporation of oxygen atoms has been simulated into either nitrogen or uranium vacancy at the UN(001) surface, sub-surface or central layers. For calculations on the corresponding slab models both the relativistic pseudopotentials and the method of

Crystal plasticity finite element simulations of cast α-uranium [PDF]

open access: yes, 2019
α-uranium, the stable phase of uranium up to 670◦C, has a base-centred orthorombic crystal structure. This crystal structure gives rise to elastic and thermal anisotropy, meaning α-uranium exhibits complex deformation and fracture behaviour ...

Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

open access: yesAnalysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Study on Improving Condensing Capacity of 30B Container

open access: yesJournal of Isotopes
Aiming at the insufficient condensation capacity of the 30B vessel in the late stage of receiving in the current uranium enrichment plant,a copper triangular heat dissipation rib was designed,and the heat dissipation performance of the 30B vessel in the ...
