Quantum precision reached in modeling molten salt behavior
ORNL researchers have developed a novel way to encapsulate salt hydrate phase-change materials within polymer fibers through a coaxial pulling process. The discovery could lead to the widespread use of the low-carbon materials as a source of insulation for a building’s envelope.
Scientists at the Department of Energy’s Oak Ridge National Laboratory are using a new modeling framework in conjunction with data collected from marshes in the Mississippi Delta to improve predictions of climate-warming methane and nitrous oxide.
Researchers demonstrated that stainless steel and other metal alloys coated with hexagonal boron nitride, or hBN, exhibit non-stick or low-friction qualities along with improved long-term protection against harsh corrosion and high-temperature.
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.
Combined heat and power (CHP) technologies, which capture and reuse waste heat from electric or mechanical power, account for about 9 percent of annual U.S. power generation. Roughly doubling that capacity could cut projected U.S. carbon dioxide emissions by 60 percent by 2030 the equivalent to tak...
Californium-252 and actinium-225 generated half of the $5 million in sales for the Department of Energy's National Isotope Data Center at ORNL in fiscal year 2008. That amount represents a $1 million increase from 2007. Californium-252 used as a start-up source in nuclear reactors, in analyzers fo...
Mathematics and sensors come together in some new ways to form a powerful tool for combating terrorism, piracy and the transport of drugs. In a project that combines resources at ORNL and Clemson University, researchers and students are using something called Level 3 sensor fusion to identify and pr...
Data from NASA's Orbiting Carbon Observatory combined with computational power and tools provided by ORNL researchers will result in unprecedented levels of information about atmospheric carbon dioxide. The satellite, scheduled for launch in mid-January, will collect precise global measurements of C...
Maps showing possible regional impacts of climate change in the Dominican Republic could play a role in setting policy there and beyond. The maps, generated by a group of researchers at Oak Ridge National Laboratory, will be used for climate change policy discussions and published in a future issue ...
Extending Daylight Saving Time by four weeks last year reduced U.S. energy consumption by 17 trillion British thermal units, or the equivalent of enough energy to power 100,000 households for a year. That's according to a report to Congress from the U.S. Department of Energy by researchers at Oak Ri...
