Adaptive one-dimensional wires operating at 1 volt could eventually pave the way for oxide electronics, such as electronic devices that mimic human brain function. Using the piezoresponse force microscopy technique, researchers at Oak Ridge National Laboratory artificially arranged ferroelectric pol...
Carefully combining materials that shrink when heated with materials that expand creates a material unaffected by extreme temperature. Researchers can apply this concept to satellites that experience drastic temperature changes as they orbit the Earth but must also maintain precise data. Researchers...
Computer hackers could lose a huge advantage because of a system being developed by a team led by Justin Beaver of Oak Ridge National Laboratory. "As we have seen in recent months, attackers who breach a system's defense have a distinct advantage because their presence is difficult to detect, they h...
Something odd happens when you expose the element gadolinium to a strong magnetic field: Its temperature jumps up. Remove the field and the temperature drops below the starting point. This behavior, known as the magnetocaloric effect, is usually found in ferromagnets, materials that lose their magne...
A recent study of diesel particulate filter performance has revealed positive news for manufacturers and industry, indicating longer service lifetime expectations than ever before. Critical to vehicle emissions control, the filter removes soot and particulates from diesel exhaust. Under excessive s...
Oak Ridge National Laboratory has received three Sustainability Awards from the Department of Energy for its achievements in energy efficiency and waste reduction.Deputy Secretary of Energy and Senior Sustainability Officer Daniel Poneman recognized the award winners today at a ceremony in Washingt...
Taking a cue from Mother Nature, researchers at the Department of Energy's BioEnergy Science Center have undertaken a first-of-its-kind study of a naturally occurring phenomenon in trees to spur the development of more efficient bioenergy crops.
A method of monitoring roots rarely used in wetlands will help Oak Ridge National Laboratory researchers effectively study the response of a high-carbon ecosystem to elevated temperatures and levels of carbon dioxide.
The Department of Energy's Oak Ridge National Laboratory has awarded a contract to Cray Inc. to increase the Jaguar supercomputer's science impact and energy efficiency. The upgrade, which will provide advanced capabilities in modeling and simulation, will transform the DOE Office of Science-suppor...
