Scientists at the Department of Energy’s Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic “building blocks” from which stable structures formed. The findings, reported in Nature Communications, provide insights that ...
For decades, biologists have believed a key enzyme in plants had one function—produce amino acids, which are vital to plant survival and also essential to human diets. But for Wellington Muchero, Meng Xie and their colleagues, this enzyme does more than advertised. They had run a series of experiments on poplar plants that consistently revealed mutations in a structure of the life-sustaining enzyme that was not previously known to exist.
A new process to identify certain microbes in women could be used to diagnose endometriosis without invasive surgery, even before symptoms start. A collaborative research team including Oak Ridge National Laboratory analyzed bacteria from a small sample of premenopausal women undergoing laparoscopic surgery for suspected endometriosis.
Dr. Michael Simpson, Oak Ridge National Laboratory Corporate Fellow and Group Leader of the Nanofabrication Research Laboratory Group in the Center for Nanophase Materials Sciences (CNMS) at ORNL, has been appointed the next director of the UT-ORNL Joint Institute for Biological Sciences (JIBS). This appointment is in addition to his role at CNMS.
Throw a rock through a window made of silica glass, and the brittle, insulating oxide pane shatters. But whack a golf ball with a club made of metallic glass—a resilient conductor that looks like metal—and the glass not only stays intact but also may drive the ball farther than conventional clubs. In light of this contrast, the nature of glass seems anything but clear.
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.
Treating cadmium-telluride (CdTe) solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why.
Vertimass LLC, a California-based start-up company, has licensed an Oak Ridge National Laboratory technology that directly converts ethanol into a hydrocarbon blend-stock for use in transportation fuels.
