KNOXVILLE—For more than seven decades, the University of Tennessee in Knoxville and Oak Ridge National Laboratory have forged special connections in a number of key areas, perhaps none stronger than the personnel that the two share.

That particular bond was on display recently when members of UT’s Office of Professional Practice office visited the facilities at ORNL, meeting more than 60 engineering students involved in summer internships at the lab.

Todd Reeves, director of the office, addressed the College of Engineering students and shared his thoughts about the importance of the work they are doing for ORNL and on leaving a good impression of themselves and their attitude.

“We talked about how special it is for them to be working in such a high-profile facility, and that it was key for them to do their best every day,” Reeves said. “More than that, we encouraged them to be enthusiastic and positive as they went about their work because it shapes the impression their managers have on them.” [Read more…]

A Chinese supercomputer kept its No. 1 spot, and Titan at Oak Ridge National Laboratory stayed at No. 2 in the latest semiannual ranking of the world’s most powerful supercomputers.

The Chinese supercomputer, Tianhe-2, was developed by China’s National University of Defense Technology, and it’s been in the top spot three times in a row on the Top500 List. Tianhe-2 bumped Titan from the top spot in June 2013.

The Chinese supercomputer performed at 33.86 petaflops—that’s 33.86 quadrillion calculations per second—on a test known as the Linpack benchmark, the press release said. Titan performed at 17.59 petaflops.

There was little change among the ranking of the world’s Top 10 supercomputers in the latest edition of the closely watched list, a press release said. The only new entry was at number 10—a 3.14-petaflop Cray XC30 installed at an undisclosed U.S. government site.

The Top500 list was announced Monday morning. The list is compiled by Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee in Knoxville, and Martin Meuer of Prometeus, Germany. [Read more…]

Oak Ridge National Laboratory will be home to two Energy Frontier Research Centers announced this week by U.S. Energy Secretary Ernest Moniz. The Department of Energy awarded a total of $100 million to 32 EFRC projects to accelerate the scientific breakthroughs needed to build the 21st-century energy economy. 

“Today, we are mobilizing some of our most talented scientists to join forces and pursue the discoveries and breakthroughs that will lay the foundation for our nation’s energy future,” Secretary Moniz said. “The funding we’re announcing today will help fuel scientific and technological innovation.”

The two ORNL EFRCs are a renewal of the Fluid Interface Reactions, Structures, and Transport (FIRST) Center, which is led by David Wesolowski, and a new award to the Energy Dissipation to Defect Evolution (EDDE) Center, led by Yanwen Zhang.

ORNL scientists also partnered on successful proposals to lay the groundwork for fundamental advances in solar energy, electrical energy storage, carbon capture and sequestration, materials and chemistry by design, biosciences, and extreme environments. Those proposals include three new projects (led by the Georgia Institute of Technology, the State University of New York–Stony Brook, and Pennsylvania State University) and three renewals (led by Washington University in St. Louis, Lawrence Berkeley National Laboratory, and the Massachusetts Institute of Technology).

KNOXVILLE—For some, getting on the Internet can be a blast.

Now, thanks to the Bandwidth for Leadership in Advancing Science and Technology project—known as BLAST—it can also be faster for computer users at the University of Tennessee in Knoxville.

A lot faster.

“This is quite an accomplishment, for both UT and for the researchers who use the network,” said Victor Hazlewood, chief operating officer at the Joint Institute for Computational Sciences and the National Science Foundation’s principal investigator on BLAST. “This really positions UT well to continue to be at the forefront of innovation.”

The upgrade, completed May 25, is a combined effort between JICS and UT’s Office of Information Technology and makes it possible for UT users to make use of Internet speeds up to 100 gigabits per second. JICS is an institute of UT and Oak Ridge National Laboratory. [Read more…]

DOE’s ARPA-E announces 13 new projects at New York Energy Week

New York, N.Y.—ARPA-E Acting Director Cheryl Martin has announced $33 million in funding for 13 new projects aimed at developing transformational fuel cell technologies for low-cost distributed power generation.

The funding was announced Thursday at New York Energy Week. ARPA-E is Advanced Research Projects Agency-Energy in the U.S. Department of Energy.

The projects, which are funded through ARPA-E’s new Reliable Electricity Based on Electrochemical Systems, or REBELS, program, are focused on improving grid stability, balancing intermittent renewable technologies, and reducing CO2 emissions using electrochemical distributed power generation systems, a press release said.

Oak Ridge National Laboratory received $2.75 million for a project titled “Nanocomposite Electrodes for a Solid Acid Fuel Cell Stack.” [Read more…]

Tim and Teresa Myrick Home Build

Habitat for Humanity of Anderson County is building a new home on Valley View Lane in Heiskell in honor of longtime volunteers Tim and Teresa Myrick, pictured at right. A family of five will live in the four-bedroom, 1,200-square-foot home. From left, they are Alexia, Amanda Cook, Edward Brown (back), Eddie (front), and Ethan.

 

HEISKELL—He’s worked on all 58 homes built by Habitat for Humanity of Anderson County during the past two decades. If his health allows, he’ll work on No. 59.

Tim Myrick, 60, is known for his community involvement, charitable contributions, and key role in the renovation of the Oak Ridge High School and modernization work at Oak Ridge National Laboratory. But now he’s battling prostate cancer. His doctor said it’s the fastest-growing he’s seen. Myrick said it spread to his bones and elsewhere within three months. In December, he was given a year to live.

“I told them that’s not going to happen,” Myrick said during a Habitat for Humanity groundbreaking ceremony this month. “I told them I have too much work to do.”

Habitat is honoring Myrick and his wife Teresa by building a home in their honor on about 1.5 acres on Valley View Lane near East Wolf Valley Road in Heiskell.

“We can’t think of anyone who has worked harder for us for a longer period of time,” said Pat Fain, HFHAC board president. [Read more…]

KNOXVILLE—Researchers at the University of Tennessee and Oak Ridge National Laboratory are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere.

Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes—called bioscavengers—so they work more efficiently against chemical weapons. The work is a joint effort between scientists at UT, ORNL, and a French national laboratory in Grenoble. Their study was published recently in the Journal of Physical Chemistry.

Nerve agents, such as sarin, are among the most highly toxic chemical weapons. The study focuses on engineering enzymes that catalyze the hydrolysis of nerve agents as a prophylactic approach to diminishing their toxic effects. [Read more…]

The Smithsonian Institution and Oak Ridge National Laboratory have announced a new partnership to support collaborative research programs and science education efforts. This is the first partnership between Oak Ridge National Laboratory and the Smithsonian, which was formalized during the signing of a memorandum of understanding, or MOU, on Thursday, June 12.

The Smithsonian and Oak Ridge National Laboratory both examine many of the world’s most complex and time-sensitive scientific problems and support many research programs that complement and reinforce each other. They also support science education to impact students and teachers from elementary school through post-doctoral studies. The MOU, signed by Smithsonian Secretary Wayne Clough and ORNL Director Thom Mason, creates a framework for future collaboration between the two organizations that leverages the strengths of each.

“The Smithsonian is proud to partner with another organization that realizes that basic research is vital to the future of the nation, and that knowledge about the natural world is inherently valuable to society,” Clough said. “This agreement will help us each maximize our strengths and achieve our common goals across a broad spectrum of scientific endeavor.” [Read more…]
