A Pilot Plant for the Reduction of Uranium Hexafluoride to Uranium Tetrafluoride with Trichloroethylene

, 1956
Pilot plant experiments are described in which trichloroethylene was used for the reduction of uranium hexafluoride to uranium tetrafluoride. After unsatisfactory preliminary results with liquid phase reduction, satisfactory results were obtained with a ...

Nationalism and Education in the Arctic: A Study of Greenland in the Context of the Kingdom of Denmark

Nations and Nationalism, EarlyView.
ABSTRACT This article analyses the coconstitution of nationalism and education in Greenland (Kalaallit Nunaat) within the Kingdom of Denmark. Drawing on Ernest Gellner, Benedict Anderson, Michael Billig and Siniša Malešević, it argues that schooling standardises language, history and civic repertoires, thereby fabricating the modern national subject ...

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Growth and characterisation of uranium multilayers. [PDF]

, 2008
This thesis investigates the extents of the 5f-3d and 5f-4f electronic interactions in U/Fe, U/Co and U/Gd thin films, where electronic hybridisation effects are expected to influence the magnetism of the U 5f states.

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Performance and Mechanism of MoS2/Octahedral Fe3O4 Composite Interface Catalytic Electrochemical Seawater Extraction of Uranium

He huaxue yu fangshe huaxue
Extracting uranium from seawater is an effective strategy for sustainable nuclear fuel supplementation. Uranium in seawater mainly exists in the form of hexavalent uranyl(U(Ⅵ)), although the total amount is large, the mass fraction of U(Ⅵ) is only 3.3×10−

Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

Terra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...
