The present study reports molecular dynamics simulations for biphasic systems comprising tributyl phosphate (TBP) in dodecane and uranyl nitrate in the aqueous phase, which are key chemical species in the well-known Pu-U extraction (PUREX) process. An attempt has been made to understand the nature of interface and mechanism of 'TBP associated uranyl' crossing under neutral and acidic conditions...

The results from this study illustrate the first time electrospray ionization-ion mobility spectrometry (ESI-IMS) has been used to separate inorganic cations in aqueous solutions. Using ESI-IMS nine inorganic cation solutions were analyzed. Counter ions affected both the sensitivity and the identity of the response ions. Aluminum sulfate, lanthanum chloride, strontium chloride, uranyl acetate, ...

Due to the ever-growing demand of energy nuclear reactor materials and the nuclear energy are now considered to be the most critical materials and source of energy for future era. Deposition of nuclear wastes in different industry, nuclear power sector are very much toxic in open environment which are hazardous to living being. There are different methods for extraction and reprocessing of thes...

Bioreduction of mobile uranyl(VI) (UO2 ) to sparingly soluble uraninite (U(IV)O2(s)) is a strategy that has been proposed for in situ remediation of uranium contaminated aquifers. That strategy faces the challenge of reoxidation of uraninite, with consequent release of soluble uranyl when the stimulation of U(VI) bioreduction is terminated. We tested the effects of supplemental organic carbon (...

A synthetic aza-cholestane amine was found to be rapidly lethal to Saccharomyces cerevisiae. Lethal action was prevented by pretreating cells with 10m uranyl nitrate. Sublethal concentrations of the steroid prevented the uptake of glucose and alanine. This demonstrated one means by which the steroid affected cell permeability, limiting the growth of the organism. Decreases in viability were rel...

Portions of this work were presented at the Annual Meeting of The American Federation for Clinical Research, Atlantic City, N. J., 5 May 1974. Received for publication 21 June 1974 and in revised form 18 November 1974. dose UN (0.047±0.013) and high dose (0.024±0.003 nVs/g kidney wt/mm Hg). Therefore UN decreases GFR by two mechanisms: (a) tubular damage leading to back-diffusion of solutes and...
