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.

Using a better modeling framework, with data collected from Mississippi Delta marshes, scientists are able to improve the predictions of methane and other greenhouse gas emissions. Credit: Matthew Berens/ORNL, U.S Dept. of Energy

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.

  Scientists applied a simple approach for growing hBN films on the surface of ubiquitous steels and other metal alloys to “armor” them and thus increase their capabilities. Credit: Adam Malin/ORNL, U.S. Dept. of Energy

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.

A clever signal noise reduction strategy developed by a team that includes Oak Ridge National Laboratory’s Ben Lawrie could dramatically improve brain imaging. By using quantum correlated beams of light, researchers reduced noise by 42 percent while doubling the signal in an optical magnetometer. ...

By analyzing a computer model output with four times the resolution of previous models, a team of researchers has perhaps explained what has been considered a serious inconsistency in the 2007 Intergovernmental Panel on Climate Change report. The findings, reported by a team that includes scientis...

With the demonstration of a 5-volt thin-film battery that can be charged and discharged 10,000 times, Oak Ridge National Laboratory’s Juchuan Li and Nancy Dudney are entering new territory. Consumers could be the big beneficiaries because these batteries boast higher energy for the same weight, lo...
