The oxidation of uranium tetrachloride
Journal of Inorganic and Nuclear Chemistry, 1966 Abstract The oxidation of uranium tetrachloride was investigated by thermo-analytical and X-ray diffraction methods. It proceeds in the presence of oxygen at atmospheric pressure via uranyl chloride (UO2Cl2) as an intermediate product: UCl 4 + O 2 → UO 2 2 Cl 2 + CL 2 3 UO 2 Cl 2 + O 2

Testing the protective efficiency of personal respiratory protection devices in radiologically contaminated environments [PDF]
Nuclear Technology and Radiation Protection, 2013 The use of ammunition primed with depleted uranium is one of the hallmarks of modern combat operations, resulting in environmental contamination by particles of depleted uranium and uranium oxide, scattered around in the form of submicron-scale ...

In situ XPS data for the uranyl-modified oxides under visible light
Data in Brief, 2018 The silica, alumina, ceria, and titania supports were modified with uranyl ions (5 wt%) and investigated using X-ray photoelectron spectroscopy. The data show the U4f photoelectron spectra and charge state of uranium for uranyl ions deposited on ...

Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles
Angewandte Chemie, EarlyView.We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.

Angewandte Chemie, EarlyView.Masked divalent yttrium and gadolinium dinitrogen complexes mediate the fragmentation of white phosphorus, converting P4 into discrete dimetallic complexes of [P4]2– and [P2]2– ligands, and an unprecedented monatomic P2– radical ligand. Structural, spectroscopic, magnetic, and DFT studies reveal insight into the bonding between these unusual Pn units ...

The Journal of Physical Chemistry, 1957 The results of kinetic, x-ray, and density studies of the UO/sub 2/ oxidation products indicate that UO/sub 2/ oxiddzes by the immediate formation of a surface gamma -tetragonal U/sub 3/O/sub 7/ phase. This process is controlled by the diffusion of oxygen through the second phase.

Thermal transport study in actinide oxides with point defects
Nuclear Engineering and Technology, 2019 We use a molecular dynamics simulation to explore thermal transport in oxide nuclear fuels with point defects. The effect of vacancy and substitutional defects on the thermal conductivity of plutonium dioxide and uranium dioxide is investigated.
