A Universally Applicable Strategy for Construction of Anti‐Biofouling Adsorbents for Enhanced Uranium Recovery from Seawater

Advancement of science, 2019
The ocean reserves 4.5 billion tons of uranium and amounts to a nearly inexhaustible uranium supply. Biofouling in the ocean is one of the most severe factors that hazard uranium extraction and even cause the failure of uranium extraction.

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

, 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

Enhanced Photocatalytic Removal of Uranium(VI) from Aqueous Solution by Magnetic TiO2/Fe3O4 and Its Graphene Composite.

Environmental Science and Technology, 2017
The separation and recovery of uranium from radioactive wastewater is important from the standpoints of environmental protection and uranium reuse. In the present work, magnetically collectable TiO2/Fe3O4 and its graphene composites were fabricated and ...

Stabilization of Tungsten-Uranium Dioxide Composites Under Thermal Cycling Conditions [PDF]

Uranium losses during thermal cycling of tungsten - uranium dioxide composites to 2500 C in flowing purified hydrogen for specimens initially containing 35 volume percent uranium dioxide were reduced by the use of thorium dioxide, calcium oxide, or ...

Joint and Rapid Determination of 210Pb-210Bi-210Po in Rock, Soil and Sediment Samples by Constant Temperature Spontaneous Deposition on Cu-foil with Gross α and Gross β Counting

Yankuang ceshi, 2013
Measurement techniques of uranium series nuclides 210Pb, 210Bi and 210Po are relatively independent at present for most cases, and there are still some technical issues that need to be overcome.

Ab initio density functional theory study of uranium solubility in Gd2Zr2O7 pyrochlore [PDF]

arXiv, 2015
In this study, an ab initio calculation is performed to investigate the uranium solubility in different sites of Gd2Zr2O7 pyrochlore. The Gd2Zr2O7 maintains its pyrochlore structure at low uranium dopant levels, and the lattice constants of Gd2(Zr2-yUy)O7 and (Gd2-yUy)Zr2O7 are generally expressed as being linearly related to the uranium content y ...
