Kansas NSF EPSCoR Director's discovery featured in the Department of Energy's Office of Science Highlights

Dr. Kristin Bowman-James
   The Department of Energy has featured Dr. Kristin Bowman-James' scientific research on their May 2, 2007 highlights page. Dr. Bowman-James is a Distinguished Professor of Chemistry at the University of Kansas and the Director of Kansas NSF EPSCoR.  She and her colleagues: Dr. Jonathan L. Sessler, Chemistry Department, University of Texas, Austin; Dr. Bruce A. Moyer, Oak Ridge National Laboratory; and Dr. Amar H. Flood, Chemistry Department, Indiana University, Bloomington, have designed molecules, called chelators, that positively impact energy production by selectively removing unwanted ions from complex solutions.These strategically designed chelators, generated in this research will selectively separate ions on demand allowing more efficient processing and safe disposal of radioactive waste.  Specifics related to the highlight can be found on the DOE Office of Science Basic Energy Sciences highlight page titled Casting a Wide Net and on the In Depth tab of Newswise.

The image above illustrates the idea that specific ions can be captured using designed molecular chelators ranging from foldamers for chloride, tetraurea chelates for sulfate, strapped calizpyrroles for lithium nitrate, and calixcrowns for cesium.

Funding for these projects was provided by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, Division of Chemical Sciences, Geosciences, and Biosciences: Jonathan Sessler (Grant No. DE-FG02-01ER15186), Bruce Moyer (Grant No. ERKCC08), Kristin Bowman-James (Grant No. DE-SC0010555), Amar Flood (Grant No. DE-FG02-09ER16068). Bruce Moyer acknowledges additional support for applied research from the U.S. Department of Energy, Office of Environmental Management.
