Reduction of TcO4- by sediment-associated biogenic Fe(II)
The potential for reduction of TcO4 (aq) to poorly soluble TcO2 · nH2O(s) by biogenic sediment-associated Fe(II) was investigated with three Fe(III)-oxide containing subsurface materials and the dissimilatory metal-reducing subsurface bacterium Shewanella putrefaciens CN32. Two of the subsurface materials from the U.S. Department of Energy’s Hanford and Oak Ridge sites contained significant amo...

متن کاملDrag Reduction by Surfactant Solutions in Gravity Driven Flow Systems
Efflux time measurements are carried out for gravity draining of a liquid from a large cylindrical tank (where the flow is essentially laminar) through single exit pipe in the absence and presence of Cetyl Pyridinium Chloride (CPC) surfactant solutions. The variables considered are initial height of liquid in the tank, dia. of tank, length of the exit pipe and concentration of surfactant. T...
متن کاملOne-electron Reduction of Pyrroloquinoline Quinone (pqq), in Aqueous Solutions: a Pulse Radiolysis Study
One electron reduction of Pyrroloquinoline quinone (PQQ) was studied using pulse radiolysis technique. Reactions of hydrated electron, H atom, radical and superoxide radicals produced very similar transient species. The radicals did not show decay in few milliseconds. The one-electron reduction potential of PQQ was determined at pH 7 using both methyl viologen and benzyl viologen couples and wa...
