Doctoral student Rachel Seibert works with ORNL mentor Kurt Terrani as part of the lab’s Nuclear Engineering Science Laboratory Synthesis (NESLS) program.

Internship program helps foster development of future nuclear scientists

For a second straight summer, Rachel Seibert spent her days at the Department of Energy’s Oak Ridge National Laboratory (ORNL) researching advanced nuclear reactors. The Ph.D. candidate may not have had such an opportunity more than a decade ago, but thanks to a unique internship ...
ORNL researcher Peter Thornton "in the field" for the Next Generation Ecosystem Experiment - Arctic.

Peter Thornton: Bridging Titan and the tundra with hands-on fieldwork

The summertime temperatures in the North Slope and Seward Peninsula of Alaska rarely reach higher than 50 degrees F and the perpetually dark winters fall below minus 20 F. It is a brutal environment for any researcher studying the Arctic ecosystem, much less a supercomputer modele...
A team from ORNL, Indiana University and Max Planck Institute in Germany has implemented a technique with Wollaston prisms to expand the capabilities currently available at ORNL’s High Flux Isotope Reactor instrument HB-1.

Addition of seventh HFIR cycle provides more research time for the user community

For the first time since 2011, scientific users of Oak Ridge National Laboratory’s High Flux Isotope Reactor were able to take advantage of a seventh cycle, allowing for 25 extra days of neutron production and available time for new experiments on HFIR’s 12 beam lines in fiscal ye...

Unraveling the Science behind Biomass Breakdown

Lignocellulosic biomass—plant matter such as cornstalks, straw, and woody plants—is a sustainable source for production of bio-based fuels and chemicals.
The theories that led to physicists Thouless, Haldane, and Kosterlitz being awarded the Nobel Prize in physics, are guiding today’s quantum physicists at ORNL in their search for materials of the future. (Image credit: ORNL/Jill Hemman)

Physics Nobel Prize winners’ work laid foundation for researchers at ORNL

The theories recognized with this year’s Nobel Prize in Physics underpin research ongoing at the Department of Energy’s Oak Ridge National Laboratory, where scientists are using neutrons as a probe to seek new materials with extraordinary properties for applications such as next-generation electronics, superconductors, and quantum computing.

Simulations Show How to Turn Graphene’s Defects into Assets

Researchers at Penn State, the Department of Energy’s Oak Ridge National Laboratory and Lockheed Martin Space Systems Company have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy...
The SNS LINAC is the most powerful proton-pulsed accelerator in the world.

SNS accelerator celebrates 10 years of leading the way

The first of its kind superconducting linear particle accelerator (LINAC) built for the Spallation Neutron Source (SNS) at the Department of Energy’s Oak Ridge National Laboratory is now celebrating 10 years of successful operations. The world-leading machine, which took 7 years...
ORNL researcher Xiaobing Liu works in the laboratory’s Building Technologies Research and Integration Center.

Xiaobing Liu: Making geothermal heat pump technology a household name

As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...

The first-ever 3D printed excavator will include a cab designed by a University of Illinois at Urbana-Champaign student engineering team and printed at DOE’s Manufacturing Demonstration Facility at ORNL using carbon fiber-reinforced ABS plastic.

First-ever 3D printed excavator project advances large-scale additive manufacturing R&D

Heavy construction machinery is the focus of Oak Ridge National Laboratory’s latest advance in additive manufacturing research. With industry partners and university students, ORNL researchers are designing and producing the world’s first 3D printed excavator, a prototype that w...

Melissa Allen’s work at Oak Ridge National Laboratory is focused on urban infrastructure and atmospheric transport, creating models to determine the effects of temperature and climate changes on human activity.

Melissa Allen: The atmosphere’s the limit

Melissa Allen, a researcher at the Department of Energy's Oak Ridge National Laboratory, is guided by her curiosity and is inspired to pursue what she loves – music, flying and climate science. And she credits her family and many mentors who have helped her along the way. Gro...
