Preparation of Uranium Nitrides from Uranium Tetrafluoride [PDF]
Journal of Nuclear Science and Technology, 1968 A method has been developed for preparing UN by two-step reaction using UF4. As a result, the reaction of UF4 with Si and N2 has proved quite practical for obtaining U2N3. It was confirmed by chemical analysis and by X-ray diffraction analysis that single phase U2N3 was obtained at reaction temperatures above 1,200°C, and only 3% of the uranium was ...

The neurotoxicology of uranium [PDF]
Toxicology, 2015 The brain is a target of environmental toxic pollutants that impair cerebral functions. Uranium is present in the environment as a result of natural deposits and release by human applications. The first part of this review describes the passage of uranium into the brain, and its effects on neurological functions and cognitive abilities.

Uranium–nitride chemistry: uranium–uranium electronic communication mediated by nitride bridges
Dalton Transactions, 2022 Sequential reduction of a uranium-azide through all the nitride steps is revealed. Experimentally determined U–U coupling in the diuranium(iv)–dinitride is shown byab initiocalculations to stem from the nitride bridges, not U–U bonding.
