A team of researchers at the Ames Laboratory has answered a key question concerning the widely-used Fenton reaction â€“ important in wastewater treatment to destroy hazardous organic chemicals and decontaminate bacterial pathogens and in industrial chemical production. The naturally occurring reaction was first discovered in 1894 by H.J.H. Fenton, a British chemist at Cambridge, and involves hydrogen peroxide (H2O2) and iron.

Pioneering mass spectrometry methods developed at the U.S. Department of Energyâ€™s (DOEâ€™s) Ames Laboratory are helping plant biologists get their first glimpses of never-before-seen plant tissue structures. The new method opens up new realms of study, ones that might have long-ranging implications for biofuels research and crop genetics.
By blending optical and atomic force microscope technologies, Iowa State University and Ames Laboratory researchers have found a way to complete 3-D measurements of single biological molecules with unprecedented accuracy and precision. Existing technologies allow researchers to measure single molecules on the x and y axes of a 2-D plane. The new technology allows researchers to make height measurements (the z axis) down to the nanometer â€“ just a billionth of a meter â€“ without custom optics or special surfaces for the samples.
Scientists at the U.S. Department of Energyâ€™s Ames Laboratory are using specialized techniques to help unravel the mysteries of a new type superconductor. The group was part of an international collaboration that found that magnetism may be helping or even responsible for superconductivity in iron-based superconductors. The results were published in the June 22 issue of Science.
Mufit Akinc, an Ames Laboratory associate and a faculty member at Iowa State University since 1981, has been named interim dean of the College of Engineering effective July 30. He succeeds Jonathan Wickert, who will assume the role of senior vice president and provost at Iowa State on the same date.
Akinc is a professor of materials science and engineering and has led the collegeâ€™s international engagement initiative since 2010. He also holds a courtesy appointment in chemical and biological engineering.
