Crown Ethers Flatten in Graphene for Strong, Specific Binding
December 18, 2014 — Ethers—simple organic molecules in which an oxygen atom bridges two carbon atoms—are the chemical building blocks of commonplace products including many solvents, propellants, cosmetics and pharmaceuticals.
December 11, 2014 — At Wednesday’s Eugene P. Wigner Distinguished Lecture, internationally recognized leader in atmospheric science Susan Solomon talked about how the intersection of science, technology, policy, communication, consumer habits and industry set a stage for success in combating ozone depletion (video).
Procter & Gamble and Temple University scientists model skin’s makeup
November 17, 2014 — Skin is the body’s largest organ. It is a protective barrier, keeping microbes out and moisture in. It also regulates temperature, enables sensation, and makes vitamin D. But researchers don’t fully understand at the molecular level how our skin performs its functions.
Spiraling Back in Time
November 17, 2014 — If you took a photograph of the Milky Way galaxy today from a distance, the photo would show a spiral galaxy with a bright, central bar (sometimes called a bulge) of dense star populations. The Sun—very difficult to see in your photo—would be located outside this bar near one of the spiral arms composed of stars and interstellar dust.
National Guard and Reserve Boss Lift program gives ORNL manager up-close view of military training
November 11, 2014 — For several years, the Department of Energy’s Oak Ridge National Laboratory has supported the National Guard and Reserve’s Boss Lift Program, which gives employers a chance to visit military installations to see first-hand what reservists do.
In August, Cindy Mayfield of the lab’s Human Resources Directorate was invited to Fort Benning, Ga.
Lasers, fish ears and environmental change
November 04, 2014 — East Tennessee is among the country’s most biodiverse regions for freshwater fish. In an abundance of shapes and colors, they swim in mountain streams and lowland lakes, sometimes ending up next to a side of garlic-mashed potatoes as a result.
Your own energy “island”? ORNL microgrid could standardize small, self-sustaining electric grids
November 04, 2014 — When Department of Energy and Oak Ridge National Laboratory researcher Yan Xu talks about “islanding,” or isolating, from the grid, she’s discussing a fundamental benefit of microgrids—small systems powered by renewables and energy storage devices. The benefit is that microgrids can disconnect from larger utility grids and continue to provide power locally.
Iron-based Superconductor Simulations Spin Out New Possibilities on Titan
October 31, 2014 — Researchers studying iron-based superconductors are combining novel electronic structure algorithms with the high-performance computing power of the Department of Energy’s Titan supercomputer at Oak Ridge National Laboratory to predict spin dynamics, or the ways electrons orient and correlate their spins in a material.
ORNL videos a gold mine for students, teachers
October 24, 2014 — A series of short videos featuring Oak Ridge National Laboratory scientists and engineers explaining their work offers a glimpse inside the world of “Big Science” for students, educators and anyone interested in the process of discovery.
Atomic trigger shatters mystery of how glass deforms
October 17, 2014 — 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.
