White House Women's Leadership Summit on Climate and Energy recognizes Argonne scientists

The White House Women’s Leadership Summit on Climate and Energy is recognizing today a select group of women experts from the public, private, academic and philanthropic sectors who are working to address climate change. Three Argonne researchers – Robin Graham, Leah Guzowski and Ann Schlenker – are part of this select group.

The superpower behind iron oxyfluoride battery electrodes

A team of scientists utilized high-energy X-rays from the U.S. Department of Energy’s Advanced Photon Source at Argonne National Laboratory to investigate the fundamental basis for the performance advantage offered by mixed-anion iron oxyfluoride conversion electrodes over electrodes made of simple oxide or fluoride phases.

In roaming radical reactions, one bond in a molecule becomes greatly extended and, before the nascent radicals completely separate, they reorient and react, leading to unexpected products.
Dynamic separability of multiple reaction pathways

Paper shows that tight and roaming pathways may be treated as separable to a good approximation. Authors identify features of the potential energy landscape that serve as mechanism dividers.

Study shows that 'brown carbon' contributes more to climate change than previously believed

Scientists at the U.S. Department of Energy’s Argonne National Laboratory have recently shown that brown carbon contributes approximately three-fourths as much of a warming effect as black carbon, despite not typically being seen as a principal contributor to climate change.

“Single crystals are ideal materials to obtain a fundamental insight into the processes that are controlling reaction rate,” said Argonne physical chemist and materials scientist Vojislav Stamenkovic.
Looking at electrocatalysis at mesoscale

In the quest to develop technologies that can efficiently convert and store energy from electrochemical systems, scientists at the U.S. Department of Energy’s Argonne National Laboratory have designed new materials that can substantially improve the performance of the current state-of-the-art electrocatalysts.
