In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming.
If such a designation existed, Nazanin Bassiri-Gharb would be on the fast track to becoming an Oak Ridge National Laboratory “super user.” Her research on nanoscale materials has taken her all across the ORNL campus, from scanning probe and electron microscopes at the Center for Nanophase Materials Sciences to neutron reflectometry at the Spallation Neutron Source and radiation equipment in the Materials Science and Technology Division.
Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries revealing that this noble metal, when structured into nanometer-sized particles, can speed up chemical reactions important in mitigating environmental pollutants and producing hard-to-make specialty chemicals.
Photovoltaic spray paint could coat the windows and walls of the future if scientists are successful in developing low-cost, flexible solar cells based on organic polymers. Scientists at the Department of Energy’s Oak Ridge National Laboratory recently discovered an unanticipated factor in the performance of polymer-based solar devices that gives new insight on how these materials form and function.
University of Tennessee (UT)-Oak Ridge National Laboratory Governor's Chair for Advanced Manufacturing Suresh Babu will lead the University of Tennessee's effort as part of a Detroit-based Lightweight and Modern Metals Manufacturing Innovation institute announced by President Obama on Feb. 25.
