Stronger stainless steel castings are critical to the regeneration of ceramic honeycomb filters used to produce cleaner exhaust systems and upgraded turbocharger housings for diesel engines. Improvements to these castings could result from test projects now under way at Oak Ridge National Laboratory...
The Department of Energy's Spallation Neutron Source has completed installation of another eagerly awaited analytical tool. SEQUOIA will be a star performer in the SNS's bevy of instruments for materials research, providing unprecedented, high-resolution neutron scattering studies of the dynamics of...
Research at Oak Ridge National Laboratory is exploring how a system of nanotubes, magnets and electrically charged particles could lead to a quicker, cheaper way to conduct DNA sequencing. The project headed by Predrag S. Krstic of ORNL's Physics Division will use a nanoscale quadrupole Paul trap, a...
The Department of Energy has just released the 27th edition of the Transportation Energy Data Book. The book, available at http://cta.ornl.gov/data/index.shtml, is produced by Stacy Davis of Oak Ridge National Laboratory's Center for Transportation Analysis. New data in thi...
Specialized skills and instruments at Oak Ridge National Laboratory are helping the world's leading manufacturer of microturbines make products expected to set new standards for performance and reliability. Capstone Turbine Corp. of California credits ORNL and the High Temperature Materials Laborato...
Fragments of tektites, natural glass objects, discovered by a team of geologists and geochemists help support a theory that a meteorite may be responsible for the sudden climate change that devastated large mammals in North America 11,000 years ago. While critics of such an extraterrestrial event ha...
Ecological risk assessments are vital for ensuring product safety, managing contaminated sites, protecting natural resources and other applications. A recent study by the Ecological Processes and Effects Committee of the U.S. Environmental Protection Agency Science Advisory Board could make risk ass...
Utilities have a new tool that provides them with a clearer picture of the wide-area electricity transmission system and enables decision-makers to respond swiftly to major power disruptions. The technology, dubbed VERDE (Visualizing Energy Resources Dynamically on Earth), combines the display capab...
Oak Ridge National Laboratory is providing technical expertise and assistance in the installation of solar energy systems and related educational materials in nearby Knoxville, Tenn., which has been selected as one of 12 Solar America Cities designated by DOE. ORNL's Energy and Transportation Scien...
By examining natural variation among cottonwood trees in nature, scientists at Oak Ridge National Laboratory hope to develop a strategy to maximize production of ethanol from cellulosic biomass. Through a process known as association mapping, scientists will attempt to identify differences in cell w...
