background: this study was undertaken to examine the reversibility of renal injury in the male new zealand white rabbits sub­se­quent to a 90-days exposure to uranyl nitrate (un) in drinking water. animals were exposed for 90 days to uranyl ni­trate in their drinking water (24 or 500mg/l). control group were given municipal tap water. methods: the indicators of kidney function measured in this ...

The complex chemistry of uranyl nitrate with mono and bi-functional neutral extractants shows, that it forms 1:2 and 1:1 complexes respectively. The structures of the isolated complexes show, that the water molecules from the primary coordination sphere of [UO2(NO3)2.2H2O] are replaced by the extractants completely and adopt a hexagonal bi-pyramidal geometry. However, the structural chemistry o...

Uranyl triflate forms with three imidazo[4,5-f]-1,10-phenanthroline ligands a propeller-like complex that exhibits a hexagonal columnar phase. The ligand is not liquid-crystalline, but a mesophase is induced upon complex formation with the uranyl salt. The thermal behavior has been investigated by polarizing optical microscopy and by high-temperature X-ray diffraction. A model of the stacking o...

The photooxidation of cellulose acetate by uranyl nitrate in acetone solutions has been investigated. Studies of the effect of the polymer on the uranyl luminescence showed an initial increase in intensity, followed by quenching. This is interpreted in terms of competition between complexation of uranyl ions by the polymer and dynamic quenching. In the quenching region, Stern-Volmer kinetics ar...

Uranyl nitrate inhibited root growth of Allium cepa at > or = 25 microM concentration. Fluorimetric analysis of metal uptake indicated the entry and accumulation of uranium into the root cell. Uranyl nitrate was neither clastogenic nor aneugenic as it failed to induce micronuclei significantly, but between 25 and 100 microM concentration, it increased significantly the frequency of sister chrom...

Near real time process monitoring of the uranium content in an aqueous fuel recycling plant is a desired component of an advanced safeguards suite; Ultraviolet– Visible spectroscopy and Time Resolved Laser induced Fluorescence Spectroscopy can contribute to this technology gap. This work presents the observation of the spectroscopic parameters (molar absorptivities, fluorescent response) of the...

Uranyl nitrate inhibited the transport of several amino acids, a vitamin, and a disaccharide into yeast.
