Crystal and electronic structures of neptunium nitrides synthesized using a fluoride route.
A low-temperature fluoride route was utilized to synthesize neptunium mononitride, NpN. Through the development of this process, two new neptunium nitride species, NpN(2) and Np(2)N(3), were identified. The NpN(2) and Np(2)N(3) have crystal structures isomorphous to those of UN(2) and U(2)N(3), respectively. NpN(2) crystallizes in a face-centered cubic CaF(2)-type structure with a space group o...
متن کاملCa3N2 and Mg3N2: unpredicted high-pressure behavior of binary nitrides.
High-pressure synthesis allows both fundamental and materials science research to gain unprecedented insight into the inner nature of materials properties at extreme environment conditions. Here, we report on the high-pressure synthesis and characterization of γ-Ca(3)N(2) and the high-pressure behavior of Mg(3)N(2). Investigation of M(3)N(2) (M = Ca, Mg) at high-pressure has been quite challeng...
متن کاملMicroscopic Characterization of Uranium Nitrides Synthesized by Oxidative Ammonolysis of Uranium Tetrafluoride
The oxidative ammonolysis route was used to synthesize three uranium nitrides, UN2, U2N3, and UN, using UF4 as the starting material. Powder XRD analysis showed the UN2 and U2N3 products to contain less than 1.0 wt % uranium oxides. UO2 level was identified to be 5.0 (0) wt % in the UN product as it is made, but this level increases upon exposure to air. The morphology of these nitrides was stu...
متن کاملIon Exchange Behavior of Zeolites A and P Synthesized Using Natural Clinoptilolite
The main goal of this study is to investigate the capability of zeolites A and P synthesized from Iranian natural clinoptilolite for uranium uptak. The removal of uranium(VI) from aqueous solution via ion exchange by zeolites in a single component system with various contact times, temperatures and initial concentrations of uranium(VI) was investigated. The experimental results we...
متن کاملBehavior of a Synthesized Bone Cement in Simulated Body Fluid
In this research, effect of soaking time of a new synthesized hydroxyapatite-based bone cement in simulated body fluid (SBF) on the final phase and strength has been studied. The powder section of the cement has been synthesized by using tricalcium phosphate, calcium carbonate and anhydrous dicalcium phosphate. The liquid phase of the cement consists of different concentrations of NaH2PO4.2H2O....
