Six East Tennessee companies doing business with Oak Ridge National Laboratory received 2014 ORNL Small Business Impact Awards from the laboratory Friday morning at a meeting of the East Tennessee Economic Council.

“This is the first time the awards have gone exclusively to regional companies,” ORNL Deputy Director for Operations Jeff Smith said. “Recognizing these firms at ETEC highlights their importance to the economic development of the region, as well as their contribution to our laboratory operations.”

The companies were recognized by ORNL’s Small Business Programs Office in categories emphasizing their specific capabilities and contributions. [Read more…]

John Holdren, assistant to the president for science and technology and director of the White House Office of Science and Technology Policy, delivered the fourth talk of the Eugene P. Wigner Distinguished Lecture Series in Science, Technology, and Policy on Thursday at Oak Ridge National Laboratory.

The lecture series started in November at in the Iran Thomas Auditorium at ORNL’s Spallation Neutron Source. Other speakers have included former Energy Secretary Steven Chu.

Oak Ridge Reservation’s emergency sectors to change

TEMA realigns boundaries to improve response

The Tennessee Emergency Management Agency will issue revised emergency sectors for the U.S. Department of Energy’s Oak Ridge Reservation on Wednesday. These sectors, labeled A-Y, determine which areas should take action if an event occurs at one of DOE’s sites locally. The new sector boundaries have improved correlation with roads, waterways, and recognizable landmarks.

“Knowing their emergency sectors will help residents better understand what to do when directed to take action by state or local emergency officials. Instructions pertaining to their safety will be issued by sector,” said Jim Bassham, TEMA director. “Periodic updates to emergency plans, like these changes, are part of TEMA’s normal review process.”

DOE and TEMA have been partners in a public information campaign aimed at the more than 50,000 people that live or work within a five-mile radius of Oak Ridge’s three main sites: the Y-12 National Security Complex, Oak Ridge National Laboratory, and East Tennessee Technology Park. An updated version of a joint publication, “What to do if an emergency occurs on the Oak Ridge Reservation,” will be available on March 12. The booklet will be on DOE’s website for area residents to read and reference at http://science.energy.gov/isc/emergency-information/. [Read more…]

SEATTLE—University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics, thanks in part to a breakthrough by researchers at Oak Ridge National Laboratory and University of Tennessee in Knoxville.

The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

Most consumer electronics use three-dimensional LEDs, but they are up to 20 times thicker than the LEDs being developed. [Read more…]

The chief engineer for the U.S. ITER Project at Oak Ridge National Laboratory will give a project overview on Tuesday.

Brad Nelson is the chief engineer for the U.S. International Thermonuclear Experimental Reactor Project. His Tuesday talk will be the first in a series of three presentations on the U.S. ITER project to Friends of ORNL, with Hans Vogel speaking on April 8 and Graeme Murdoch speaking on May 13.

The New Yorker published a story on ITER in its March 3 edition titled “A Star in a Bottle” by Raffi Khatchadourian.

Nelson’s Tuesday presentation during a Friends of ORNL luncheon lecture starts at noon at the University of Tennessee Resource Center in Oak Ridge. [Read more…]

Vertimass LLC and ORNL Ethanol Fuel

Vertimass LLC has licensed an ORNL technology that converts ethanol into a hydrocarbon blend-stock for use in transportation fuels. ORNL inventors (from left) Chaitanya Narula, Brian Davison, and Martin Keller display the technology with Vertimass chairman William Shopoff.

Vertimass LLC, a California-based start-up company, has licensed an Oak Ridge National Laboratory technology that directly converts ethanol into a hydrocarbon blend-stock for use in transportation fuels.

The ORNL technology offers a new pathway to biomass-derived renewable fuels that can lower greenhouse gas emissions and decrease U.S. reliance on foreign sources of oil.

“Vertimass is very pleased to be partnering with ORNL to commercialize this revolutionary technology that can broaden the market for alternative fuels, ” said Vertimass chairman William Shopoff. “We have assembled a team of industry and technology leaders, including Dr. Charles Wyman, our president and CEO, who will take this novel catalyst from the lab to the marketplace. We see this technology as a significant step in moving the United States toward energy independence.”

The technology developed by ORNL’s Chaitanya Narula, Brian Davison and Associate Laboratory Director Martin Keller uses an inexpensive zeolite catalyst to transform ethanol into hydrocarbon blend-stock. The resulting liquid can be blended at various concentrations into gasoline, diesel, and jet fuels without negatively affecting engine performance. After mixing with petroleum-derived fuels, the blend-stock does not require modifications to the existing distribution infrastructure. [Read more…]

KNOXVILLE—The University of Tennessee in Knoxville will be part of a national effort, announced Tuesday by President Barack Obama, that could lead to more fuel-efficient cars and decreased costs for ships and aircraft.

Suresh Babu, UT-Oak Ridge National Laboratory Governor’s Chair for Advanced Manufacturing, and a team of faculty will help lead UT’s research effort in the $140 million Detroit-based institute, called the Lightweight and Modern Metals Manufacturing Innovation, or LM3I—one of two institutes announced Tuesday.

The U.S. Department of Defense-funded facility pairs together aluminum, titanium, and high-strength steel manufacturers with universities and laboratories pioneering new technology development and research for consumer products and defense capabilities. [Read more…]

UT hosts top nuclear engineering students, who meet Oak Ridge reps

KNOXVILLE—Some of the best and brightest undergraduate students from around the United States gathered at the University of Tennessee in Knoxville recently for the chance to meet top experts in the field of nuclear engineering, including representatives from federal sites in Oak Ridge.

“This area really is the birthplace of a lot of activities related to nuclear engineering,” said Wesley Hines, head of UT’s Department of Nuclear Engineering, which sponsors the annual event. “Some of these kids don’t realize all of the nuclear-related opportunities that exist here until they do this program. What we hope to achieve is to let people see all that is possible, all that is already in place when they come here.”

The sessions gave prospective graduate students a chance to mingle with some of the biggest names in nuclear research and energy, including from the Y-12 National Security Complex, Oak Ridge National Laboratory, the UCOR facilities at the East Tennessee Technology Park, and Tennessee Valley Authority, as well as with UT faculty and students.  [Read more…]

ORHS team will compete in National Science Bowl

High school students from across Tennessee competed on Saturday, Feb. 22, at Pellissippi State Community College’s Blount County Campus, in the U.S. Department of Energy’s Tennessee Science Bowl competition. Fifty-five high school teams comprised of four students, and one alternate student, answered challenging mathematical problems and tested their knowledge in broad disciplines including chemistry, biology, earth and space science, physics, and energy.

Training for months after school, the student competitors committed hours of study to expanding and honing their mathematics and science knowledge and competition skills. And, all their work showed. Many of the competition rounds came down to the last nail-biting seconds before a winner emerged. However, in the end, Oak Ridge High’s Team 1 edged out their competitors, placing first.

Oak Ridge High School received a $1,000 cash prize, a first-place trophy, and an all-expenses-paid trip to the DOE National Science Bowl in Washington, D.C., from April 24-28, when they will compete against other winning teams from around the nation. [Read more…]
