Oleg Pestovsky, (left), Andreja Bakac (seated) and Hajem Bataineh
(right), researchers at the US Department of Energy's Ames
Laboratory, have proved the widely used Fenton reaction can take
different paths and form different reaction intermediates depending on
the pH of the reaction environment. Pestovsky and Bakac are both
scientists at Ames Laboratory. Bataineh is a graduate student at Iowa
State University's Department of Chemistry.
