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.
