Improving wildfire predictions with Earth-scale climate models

DOE/Oak Ridge National Laboratory

Wildfires have shaped the environment for millennia, but they are increasing in frequency, range and intensity in response to a hotter climate. The phenomenon is being incorporated into high-resolution simulations of the Earth’s climate by scientists at the Department of Energy’s Oak Ridge National Laboratory, with a mission to better understand and predict environmental change.

UT-Battelle, LLC, has appointed Stephen K. Streiffer to be the next director of Oak Ridge National Laboratory. He currently serves as interim director at SLAC National Accelerator Laboratory and will join ORNL in October.

Geoscientists aim to improve human security through planet-scale POI modeling

DOE/Oak Ridge National Laboratory

Through an intelligent combination of geotagged social media, global location and natural language data, ORNL’s Junchuan Fan and Gautam Thakur developed MapSpace, a publicly available, scalable land-use modeling framework. By providing data characteristics broader and deeper than satellite imagery alone, MapSpace can generate population analytics invaluable for urban planning and disaster response. The researchers’ findings were published in the International Journal of Digital Earth.

Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Early experiments at the Department of Energy’s Oak Ridge National Laboratory have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.

At ORNL, 18 nuclear analytical chemistry methods get international stamp of approval

DOE/Oak Ridge National Laboratory

The International Standards Organization has put its stamp of approval on 18 nuclear analytical chemistry methods at the Department of Energy’s Oak Ridge National Laboratory. These testing and calibration methods have received ISO 17025 accreditation. “Accreditation serves DOE missions in environmental stewardship, isotope production and nuclear security,” said Joe Giaquinto, head of ORNL’s Nuclear Analytical Chemistry section.

Scientists use ORNL’s Summit supercomputer to learn how cicada wings kill bacteria

DOE/Oak Ridge National Laboratory

Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to products with inherently antibacterial surfaces that are more effective than current chemical treatments.
