Molecular beam study of photoionization of uranium and uranium oxide

Optics Communications, 1983
Abstract Crossed laser molecular beam configuration was used to study the photoionization of U and UO by the UV-lines of an argon ion laser. Photoionization efficiencies of both U and UO were found to be line sensitive. Photoionization by the 3638 A line was observed for the first time.

Marinobacter sp. Stable Hydrous Titanium Oxide Functionalized Bovine Serum Albumin Nanospheres for Uranium Capture from Spiked Seawater.

ACS Applied Materials and Interfaces, 2019
A novel nano-spherical hydrous titanium oxide adsorbent (HTO-BSA-NSs) was prepared by immobilizing HTOs with a manipulated molecular mass and number of active sites for uranium on the surface of BSA-NSs.

The oxidation of uranium dioxides

Journal of Biochemical Toxicology, 1965
AbstractThe oxidation of three types of uranium dioxide (UO2) material has been investigated in the 120—360° range.In UO2 powders, of surface area greater than about 2 m.2/g., oxidation was diffusion‐controlled up to U3O7 which oxidised to U3O8 above about 240°.

Electrolytic Production of Uranium Metal from Uranium Oxides

Industrial & Engineering Chemistry Process Design and Development, 1962
Massive uranium metal which exceeds AEC specifications for purity was produced with nearly 100% recovery from uranium oxides. Electrolysis at 1150 deg C in a fused fluoride electrolyte produces molten metal. Oxides are excluded from the metal product to obtain well coalesced metal, by incorporating the oxide to be reduced in a consumable uranium oxide--

Metal-organic frameworks (MIL-68) decorated graphene oxide for highly efficient enrichment of uranium

Journal of the Taiwan Institute of Chemical Engineers / Elsevier, 2019
A novel adsorbent, metal organic framework (MIL-68) decorated graphene oxide (MIL-68/GO) composites were prepared in this study. The synthesized sorbent was well-characterized by Transmission Electron Microscope (TEM), X-ray Diffraction (XRD) and Fourier

Chemical reactivity of oxide materials with uranium and uranium trichloride

Korean Journal of Chemical Engineering, 2010
A graphite crucible is used for the manufacturing of uranium ingots in the uranium casting equipment of the electrorefining process. Uranium and uranium alloys are typically induction melted in graphite crucibles under a vacuum condition; however, due to the chemical reactivity of uranium and most alloying elements with carbon, a protective ceramic ...

Corrosion Properties of Oxidized Metallic Uranium and Uranium Carbide

ECS Meeting Abstracts
The long-term strategy for nuclear waste disposal involves the isolation and containment of spent fuel in a deep geological repository (DGR). CANDU fuel pellets are made from uranium dioxide, which exhibits exceptional wasteform properties due to its remarkably low solubility under the neutral or slightly alkaline conditions expected in a DGR ...
