ORNL drone and geospatial team becomes first to map the Coca River in the Amazon basin as erosion and sediment threaten Ecuador’s lands.
Electric vehicles can drive longer distances if their lithium-ion batteries deliver more energy in a lighter package. A prime weight-loss candidate is the current collector, a component that often adds 10% to the weight of a battery cell without contributing energy.
Jack Orebaugh, a forensic anthropology major at the University of Tennessee, Knoxville, has a big heart for families with missing loved ones. When someone disappears in an area of dense vegetation, search and recovery efforts can be difficult, especially when a missing person’s last location is unknown. Recognizing the agony of not knowing what happened to a family or friend, Orebaugh decided to use his internship at the Department of Energy’s Oak Ridge National Laboratory to find better ways to search for lost and deceased people using cameras and drones.
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.
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.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated an additive manufacturing method to control the structure and properties of metal components with precision unmatched by conventional manufacturing processes. Ryan D...
Complex oxides have long tantalized the materials science community for their promise in next-generation energy and information technologies. Complex oxide crystals combine oxygen atoms with assorted metals to produce unusual and very desirable properties.
Blowing bubbles may be fun for kids, but for engineers, bubbles can disrupt fluid flow and damage metal.
Keeping food fresh is no easy feat. Trials of transporting ice over long distances and the hazards of systems that rely on toxic gases riddle the pages of refrigeration history. And although cooling science has come a long way in the past two centuries, modern refrigeration has an environmental cost...
