Theoretical Study of the Structure and Reactions of Uranium Fluorides
Uranium is an actinide metal mostly known for its use as fuel at nuclear power plants. Once the amount of fissile isotope (U) in nature is not enough for a chain reaction, uranium must be enriched in order to achieve roughly 4% of the 235 isotope. Therefore, it is converted into UF6, a gaseous compound, which can be used in isotope separation techniques (being centrifugation the most used and l...
متن کاملOxidative ammonolysis of uranium(IV) fluorides to uranium(VI) nitride
Actinide nitrides, in particular UN, are being considered as fuel types for advanced reactor systems. Here, we demonstrate a low-temperature synthesis route on uranium that could be developed into a commercial fabrication process for UN and mixed actinide nitride fuels. UN was successfully synthesized from UO2 by first reacting with NH4HF2 in a ball mill at 20 C to form tetravalent ammonium ura...
متن کاملON THE REACTIONS IN ILMENITE, ALUMINUM AND GRAPHITE SYSTEM
Al2O3/TiC composites are used as cutting tools for machining gray cast iron and steels. The addition of iron improves the toughness of Al2O3/TiC composites. Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites. However, the formation mechanism and reaction sequences of this system are not clear enough. Therefore, the present research is designed to determ...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
متن کاملSelf-Propagating Domino-like Reactions in Oxidized Graphite
Graphite oxide (GO) has received extensive interest as a precursor for the bulk production of graphene-based materials. Here, the highly energetic nature of GO, noted from the self-propagating thermal deoxygenating reaction observed in solid state, is explored. Although the resulting graphene product is quite stable against combustion even in a natural gas fl ame, its thermal stability is signi...
