Graphene, a single-layer sheet of graphite, has potential as a remarkable material, particularly for electronics and composite applications. However, working with the material leaves molecular-scale rough edges, which spoil its properties. Theory-based computer simulations performed by researchers a...
Information sharing technologies at the heart of Web 2.0 are being integrated into an Oak Ridge National Laboratory freight tracking system that could revolutionize the industry. Most importantly, IntelligentFreight will add a level of communication and safety beyond what is in place today, accordin...
Construction and installation has been completed recently on the newest instrument at the Department of Energy's Spallation Neutron Source at Oak Ridge National Laboratory. The Single-Crystal Diffractometer, also known as TOPAZ, will greatly expand the range of materials explored in chemistry, earth...
Thin-layer chromatography, a lab technique for separating mixtures, produces high-resolution separations faster and at lower costs than other methods. But TLC doesn't work well with mass spectrometry, which uses other separation methods such as higher performance liquid chromatography to identify or...
Oak Ridge National Laboratory is partnering with SBE Inc., a Barre, Vt., power and electronics firm, to help test and improve electric vehicle capacitors. The Power Electronics and Electric Machinery Research Center, part of ORNL's Energy and Transportation Science Division, will assess and evaluate...
Even the smallest detail has been included in an Oak Ridge National Laboratory study that examines the consumption and release of carbon by humans. The study provides calculations for carbon intake, expiration and excretions of people, and includes a geographical map that paints a clear picture of w...
Specialized cameras at weigh stations in Kentucky are helping ensure that operators of commercial vehicles are abiding by all state and federal laws with the payoff expected to be safer highways and more money in the coffers of the Bluegrass State. The system takes advantage of a technology develope...
A first-ever systematic study of the effectiveness of reverse 911 calls shows it worked like a charm and saved lives when fires consumed 368,340 acres and 1,600 structures in San Diego County in 2007. A team led by John Sorensen and Barbara Vogt of Oak Ridge National Laboratory concluded that its fi...
Researchers at the Department of Energy's Spallation Neutron Source at Oak Ridge National Laboratory set a new world record at the end of the most recent run by creating 155 trillion protons in a single pulse and delivering that pulse to the SNS mercury target. The test exceeds the SNS design intens...
People producing child pornography and using the Internet to share their material could be living dangerously because of a technology developed at Oak Ridge National Laboratory and the Y-12 National Security Complex. The system employs software agents to rapidly and thoroughly scan confiscated hard ...
