With a 3-D printed twist on an automotive icon, the U.S. Department of Energy’s Oak Ridge National Laboratory is showcasing additive manufacturing research at the 2015 North American International Auto Show in Detroit.

ORNL’s newest 3-D printed vehicle pays homage to the classic Shelby Cobra in celebration of the racing car’s 50th anniversary. The 3-D printed Shelby will be on display January 12-15 as part of the show’s inaugural Technology Showcase.

Researchers printed the Shelby car at DOE’s Manufacturing Demonstration Facility at ORNL using the Big Area Additive Manufacturing, or BAAM, machine, which can manufacture strong, lightweight composite parts in sizes greater than one cubic meter. The approximately 1,400-pound vehicle contains 500 pounds of printed parts made of 20 percent carbon fiber. [Read more…]

New methods are improving connections between private businesses and technology from the Oak Ridge National Laboratory, with 101 licenses and options executed during the last three years.

Mike Paulus, director of Technology Transfer, attributes the growth in large part to the Technology Innovation Program, Bridging the Gap, and SPARK! These programs helped the lab double the number of licenses for the fiscal years 2012-2014 compared to 2009-2011, and Paulus expects a new initiative, the Invention to Innovation Webinar Series, to help maintain the upward trend.

“We have a talented staff that has worked very hard to identify, develop, and market high-potential technologies that provide the best opportunities to licensees,” Paulus said. “Our two-pronged approach focuses on increasing the overall deal volume while at the same time concentrating on our most promising technologies.” [Read more…]

About 30 students ages nine through 14 are gearing up for the 2014-15 FIRST LEGO League competition with weekly training sessions at the National Transportation Research Center in West Knoxville. NTRC is part of the U.S. Department of Energy’s Oak Ridge National Laboratory, and ORNL operating contractor UT-Battelle co-sponsors the LEGO League tournament.

“This year’s theme is ‘World Class Learning Unleashed,’” said Claus Daniel, an ORNL researcher who’s coaching one of three teams meeting at the NTRC. “Part of what the students are doing is defining a question, research, how people learn about the question nowadays and then original ideas to improve the learning process.” [Read more…]

The High Flux Isotope Reactor, or HFIR, now in its 48th year of providing neutrons for research and isotope production at Oak Ridge National Laboratory, has been designated a Nuclear Historic Landmark by the American Nuclear Society.

“This designation from the ANS recognizes HFIR’s role in the history of the nuclear age, but it also speaks to the excellence of its design and operation,” ORNL Director Thom Mason said. “HFIR remains one of the world’s most capable reactor-based neutron science, radioisotope production, and materials irradiation facilities, and we expect that to continue for many years.”

The designation was proposed by the ANS honors and awards committee and approved on initial ballot by the board of directors.

“The ANS Nuclear Historic Landmark signifies that a nuclear facility has played an important role in nuclear science and engineering,” ANS President Michaele C. Brady Raap said. “HFIR, with its preeminent role in isotope production and neutron science, certainly meets that criteria.”

The reactor was conceived in the late 1950s as a production reactor to meet anticipated demand for transuranic isotopes (“heavy” elements such as plutonium and curium). HFIR today is a U.S. Department of Energy Office of Science User Facility and one of the world’s sole sources of the radioisotope californium-252, used in industry and medicine. ORNL is a DOE lab.

Renowned mammalian geneticist Liane Russell returned Thursday to Oak Ridge National Laboratory to congratulate the first recipients of a new fellowship named in her honor.

ORNL created the Liane Russell Distinguished Early Career Fellowship to attract a diverse and promising work force of early career scientists and engineers whose interests align with DOE missions.

“It is gratifying to see these opportunities being made available to a diverse group of talented young people because, sadly, in the scientific fields this has not always been the case,” Russell said. “For this reason I am particularly honored to have my name attached to the fellowships.”

The competitive, three-year fellowship is aimed toward establishing long-term research careers at ORNL. It is available to outstanding scientists and engineers who have received their doctorate degrees within the past seven years, with emphasis given to attracting women and minority candidates.

The first three Russell fellows, recognized at Thursday’s reception, are: [Read more…]

Recycled Tire Battery Schematics

Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at Oak Ridge National Laboratory.

By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries. An anode is a negatively charged electrode used as a host for storing lithium during charging.

The method, outlined in a paper published in the journal RSC Advances, has numerous advantages over conventional approaches to making anodes for lithium-ion batteries.

“Using waste tires for products such as energy storage is very attractive not only from the carbon materials recovery perspective but also for controlling environmental hazards caused by waste tire stock piles,” Paranthaman said.

The ORNL technique uses a proprietary pretreatment to recover pyrolytic carbon black material, which is similar to graphite but man-made. When used in anodes of lithium-ion batteries, researchers produced a small, laboratory-scale battery with a reversible capacity that is higher than what is possible with commercial graphite materials.

ORNL scientists uncover clues to role of magnetism in iron-based superconductors

Magnetism of Iron-based Superconductors

New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at Oak Ridge National Laboratory and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism.

The study published in Advanced Materials provides experimental evidence that local magnetic fluctuations can influence the performance of iron-based superconductors, which transmit electric current without resistance at relatively high temperatures.

“In the past, everyone thought that magnetism and superconductivity could not coexist,” said ORNL’s Claudia Cantoni, the study’s first author. “The whole idea of superconductors is that they expel magnetic fields. But in reality things are more complicated.”

Superconductivity is strongly suppressed by the presence of long-range magnetism—where atoms align their magnetic moments over large volumes—but the ORNL study suggests that rapid fluctuations of local magnetic moments have a different effect. Not only does localized magnetism exist, but it is also correlated with a high critical temperature, the point at which the material becomes superconducting. [Read more…]
