Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered they can control chemical reactions in a new way by creating different shapes of cerium oxide, a rare-earth-based catalyst.
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.
New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at the Department of Energy’s Oak Ridge National Laboratory and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism.
Five Department of Energy Oak Ridge National Laboratory physicists, including Deputy for Science and Technology Ramamoorthy Ramesh, have been named by Thomson Reuters as some of the best and brightest of our time.
A novel combination of microscopy and data processing has given researchers at the Department of Energy’s Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties.
The Department of Energy’s Oak Ridge National Laboratory has launched the Institute for Functional Imaging of Materials to accelerate discovery, design and deployment of new materials.
Oak Ridge National Laboratory will be home to two Energy Frontier Research Centers (EFRCs) announced this week by U.S. Energy Secretary Ernest Moniz.
Knoxville-based Fiveworx has licensed an Oak Ridge National Laboratory technology that will help consumers reduce their utility bills by analyzing their home energy usage.
