From the bluebird painting propped against her office wall and the deer she mentions seeing outside her office window, Linda Lewis might be mistaken for a wildlife biologist at first glance. But rather than trailing animal tracks, Lewis, a researcher at the Department of Energy’s Oak Ridge National Laboratory, is more interested in marks left behind by humans.
With more than 30 patents, James Klett is no stranger to success, but perhaps the Oak Ridge National Laboratory researcher’s most noteworthy achievement didn’t start out so hot – or so it seemed at the time.
Andrew Stack, a geochemist at the Department of Energy’s Oak Ridge National Laboratory, advances understanding of the dynamics of minerals underground.
Scientists who bridge disciplines often take research in new directions. Andrew Stack of the Department of Energy’s Oak Ridge National Laboratory calls on his expertise in geology, chemistry and computing to advance understanding of the dynamics of minerals underground. Working in the Geochemistry a...
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.
Scientific research may be the primary focus of the Department of Energy’s national laboratories, but for David Mandrus, the institutions play an equally important role in shaping the instruction and career paths of students.
When Orlando Rios first started analyzing samples of carbon fibers made from a woody plant polymer known as lignin, he noticed something unusual. The material’s microstructure -- a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix -- looked almost too good to be true.
A new concept in metallic alloy design – called “high-entropy alloys” - has yielded a multiple-element material that not only tests out as one of the toughest on record, but, unlike most materials, the toughness as well as the strength and ductility
Researchers at the Department of Energy’s Oak Ridge National Laboratory got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra “switch” that brings new functionalities to materials when “flipped” by external stimuli such as electric fields or mechanical strain. This makes polar materials useful for devices such as sensors and actuators.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered they can control chemical reactions in a new way by creating different shapes of cerium oxide, a rare-earth-based catalyst.
