Nanofibers yield stronger, tougher carbon fiber composites
In the hope of bringing criminals more swiftly to justice and giving greater closure to grieving families, the Department of Energy's Oak Ridge National Laboratory has licensed a new remote sensing technology to Agile Technologies of Knoxville. Agile Technologies developed a special suite of s...
Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries for controlling band gaps.
Molecular-level studies of tension wood formation in poplars could ultimately fuel the discovery of biomass crops with thicker cell walls, less lignin and more cellulose that can be converted into ethanol. While typical poplar woody biomass is composed of about 45 percent cellulose, tension wood cel...
Changing the behavior of a material isn't big magic? it's nanoscale chemistry. Alejandro Lopez-Bezanilla used the computing power of Oak Ridge National Laboratory's Jaguar supercomputer, America's fastest, to study the effects of adding oxygen, sulfur and hydrogen to nanoribbons made of boron nitri...
An upgrade is transforming Oak Ridge National Laboratory's Jaguar supercomputer, America's fastest, into Titan, a next-generation supercomputer that will employ the latest AMD Opteron central processing units as well as NVIDIA Tesla graphics processing units ? energy-efficient processors that accele...
A combination of advanced techniques at Oak Ridge National Laboratory helped researchers gain a better understanding of how some proteins attack bacteria. Colicins, a family of protein toxins, kill E. coli by crossing the bacterial membrane to exert their toxic effects. One family member, Colicin N,...
By selectively applying different coatings, scientists have discovered they can influence the toxicity of particles on mouse cell lines from the lung and immune system. These findings, published in Langmuir, build on previous work that showed surface coatings can influence toxicity to bacteria. "The...
Studies of bacteria first found in Yellowstone's hot springs are furthering efforts at the Department of Energy's BioEnergy Science Center toward commercially viable ethanol production from crops such as switchgrass.
Individual atoms can make or break electronic properties in one of the world's smallest known conductors—quantum nanowires.
Steven J. Zinkle, a senior materials researcher at the Department of Energy's Oak Ridge National Laboratory, has been elected to the National Academy of Engineering (NAE).
