Spiral-tip motion combined with image reconstruction techniques is an approach that can help scientists better understand the behavior of an electric charge at the microscopic level, vital for improving batteries and electronic devices. Credit: Stephen Jesse/ORNL, U.S. Dept. of Energy

Research led by ORNL’s Marti Checa and Liam Collins has pioneered a groundbreaking approach described in the journal Nature Communications that enables visualizing charge motion at the nanometer level, or one billionth of a meter, but at speeds thousands of times faster than conventional methods.

ORNL climate modeling expertise contributed to a project that assessed global emissions of ammonia from croplands now and in a warmer future, while also identifying solutions tuned to local growing conditions.

An encapsulation system developed by ORNL researchers prevents salt hydrates, which are environmentally friendly thermal energy storage materials, from leaking and advances their use in heating and cooling applications. Credit: Andy Sproles/ORNL, U.S. Dept. of Energy

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.
