Five-year contract could be worth $135 million

Information International Associates, or IIa, has been awarded a major 100-person, multi-year contract with the U.S. Patent and Trademark Office to provide a wide range of information technology support, a press release said.

The USPTO is headquartered in Alexandria, Virginia, and it is an agency within the U.S. Department of Commerce. Its mission is “to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writing and discoveries” and to support the federal registration of trademarks.

“IIa continues to grow and to be recognized as a leader in IT services,” said IIa owner and Chief Executive Officer Bonnie C. Carroll. “In the past year alone, we have been awarded multiple new IT contracts in addition to our ongoing support to the U.S. Department of Energy Office of Scientific and Technical Information operations in Oak Ridge and at DOE Headquarters in Washington, D.C., and our contracts for IT infrastructure at the Nuclear Regulatory Commission in Maryland.”

In September 2013, II was awarded a U.S. Department of Defense contract to operate the DoD Homeland Defense and Security Information Analysis Center. In January 2014, IIa won a major, basic ordering agreement with Oak Ridge National Laboratory to provide a wide range of IT support to the laboratory during the next five years. [Read more…]

Dragon Boats Close Race

 

To the Editor:

What happens when three Rotary clubs in an East Tennessee city work together? In Oak Ridge, a three-club collaboration over the past year culminated in a highly successful inaugural Oak Ridge Dragon Boat Race Festival. The exciting event was launched on Saturday, May 31, at the Oak Ridge Marina off Melton Lake Drive—one of the three best rowing venues in the United States.

The leadership of the event started with Mark Watson, Oak Ridge city manager and president of the Rotary Club of Oak Ridge. He met frequently with the presidents of the Oak Ridge Breakfast Rotary and Oak Ridge Sunset Rotary clubs, and they persuaded their club members to serve on the organizing committee and as volunteers at the festival. Key Rotarians who made the event successful were Leslie England, Keith Kahl, Jim Sumner, and Oak Ridge City Councilman Chuck Hope (who was in charge of logistics and served as a liaison between the Rotary clubs and the city of Oak Ridge).

By the third week in May, 30 teams, including one from Chattanooga and three from Kentucky and North Carolina, had registered. Three teams came from the Oak Ridge School System and three from Oak Ridge National Laboratory (ORNL). [Read more…]

NNSA marks 10th anniversary of Global Threat Reduction Initiative

WASHINGTON, D.C.—The National Nuclear Security Administration on Thursday marked the 10th anniversary of the Global Threat Reduction Initiative, GTRI. Since the Sept. 11 attacks, reducing the threat of terrorist acquisition of nuclear or radiological material has been a core mission of NNSA, and it is a mission that will continue into the future.

“The Global Threat Reduction Initiative’s history demonstrates how seriously we take this mission and our commitment to fulfilling President Obama’s nuclear security agenda,” said U.S. Department of Energy Under Secretary for Nuclear Security and NNSA Administrator Frank G. Klotz. “However, the threat to national and global security from state or terrorist acquisition of nuclear and radiological materials is far from gone, and our focus now is on addressing the substantial threats that remain.”

GTRI, an NNSA nuclear nonproliferation program, works with partners around the world to reduce and consolidate global stockpiles of highly enriched uranium, or HEU, and plutonium, and to secure dangerous radiological sources both at home and abroad. GTRI and its predecessor programs have removed and secured more than enough material for 980 nuclear weapons and tens of thousands of radiological dirty bombs by converting HEU research reactors and isotope production facilities to the use of low enriched uranium, or LEU; removing or confirming disposition of HEU and plutonium; and securing nuclear and radiological sites around the world.

A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research, and harvesting water from fog.

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have developed a method to create air-stable water droplet networks known as droplet interface bilayers. These interconnected water droplets have many roles in biological research because their interfaces simulate cell membranes. Cumbersome fabrication methods, however, have limited their use.

“The way they’ve been made since their inception is that two water droplets are formed in an oil bath then brought together while they’re submerged in oil,” said ORNL’s Pat Collier, who led the team’s study published in the Proceedings of the National Academy of Sciences. “Otherwise they would just pop like soap bubbles.”

Instead of injecting water droplets into an oil bath, the ORNL research team experimented with placing the droplets on a superhydrophobic surface infused with a coating of oil. The droplets aligned side by side without merging. [Read more…]

KNOXVILLE—Two students were the first to earn a new doctoral degree this month from the Energy Science and Engineering program founded by former Gov. Phil Bredesen in partnership with the University of Tennessee in Knoxville and Oak Ridge National Laboratory.

The General Assembly approved the program in a special session on education in January 2010. The first class enrolled in the Bredesen Center for Interdisciplinary Research and Graduate Education in fall 2011, and it is now one of UT’s fastest-growing graduate programs.

Scott Curran and Vincent Kandagor earned their doctorates in energy science and engineering at UT’s graduate hooding on Thursday, May 8.

“We’re awfully proud of Scott and Vincent,” said Bredesen Center Director Lee Riedinger. “They both transferred into our program once we’d started and were able to really shine, to really do some positive things.” [Read more…]

ORNL paper examines clues for superconductivity in an iron-based material

For the first time, scientists have a clearer understanding of how to control the appearance of a superconducting phase in a material, adding crucial fundamental knowledge and perhaps setting the stage for advances in the field of superconductivity.

The paper, published in Physical Review Letters, focuses on a calcium-iron-arsenide single crystal, which has structural, thermodynamic, and transport properties that can be varied through carefully controlled synthesis, similar to the application of pressure. To make this discovery, researchers focused on how these changes alter the material’s Fermi surface, which maps the specific population and arrangement of electrons in materials.

“The Fermi surface is basically the ‘genetic code’ for causing a certain property, including superconductivity, in a material,” said Athena Safa-Sefat of the U.S. Department of Energy’s Oak Ridge National Laboratory, which led the research team. “We can make different phases of this material in single crystal forms and measure their structure and properties, but now we have Fermi surface signatures that explain why we can’t induce superconductivity in a certain structural phase of this material.” [Read more…]

Roane State Community College’s composite materials courses were just the challenge Dana Hudson wanted.

Hudson, of Knoxville, completed three introductory courses in composite materials through the college’s Advanced Composites Employment, or ACE, program. Hudson had taken college courses on and off for years. Her previous college work paid off because the number of college credits Hudson had completed qualified her to take the composite materials courses at no cost.

“It was a great experience, and it challenged me in some ways that I needed to be challenged,” Hudson said. “I learned a lot, and the courses added to my resume. The first night I was ready to quit, but I stuck with it and learned a lot, and I feel very proud of the achievement. Like I told my kids, you are never too old to learn.”

Roane State offers specialized composite materials courses as part of its Associate of Applied Science (A.A.S.) degree in General Technology. Composite materials, such as carbon fiber, are used to make automotive body parts, pontoon boats, wind turbine blades, and much more. [Read more…]

Hail, Double Rainbow!

“Notice that the colors in the rare secondary rainbow are reversed from those of the primary rainbow,” said Herb Krause, retired Oak Ridge National Laboratory physicist. “The primary rainbow is caused by a single reflection of sunlight in each raindrop, and the secondary rainbow is caused by a double reflection.”

KNOXVILLE—Researchers from the University of Tennessee in Knoxville recently garnered national attention for their part in a study that could lead to the development of tablets, televisions, and mobile devices the width of a piece of paper.

First published in Nature, the article details how researchers have been able to create wires only three atoms wide using an electron beam.

The lead researcher on the project was Vanderbilt Ph.D. student Junhao Lin, who was a visiting scientist at Oak Ridge National Laboratory at the time.

Through the ORNL connection, UT’s Stephen Pennycook, David Mandrus, and Jiaqiang Yan—all of the College of Engineering’s Department of Materials Science and Engineering—got involved. [Read more…]

But hundreds of jobs maintained in Ohio and Tennessee, USEC says

Babcock and Wilcox has terminated the employment of more than 100 workers who had been involved in the American Centrifuge project with USEC, and Monday was the last day of work for most of them, a spokesperson said.

“B&W’s involvement in the American Centrifuge Manufacturing LLC has transitioned fully to USEC, which will result in the termination of all 122 employees B&W had engaged in the effort,” said Aimee Mills, B&W media relations lead.

Mills said roughly 25 employees will be released during the next two months as the “final steps of demobilization take place” on the advanced uranium enrichment project, which has included centrifuge manufacturing in Oak Ridge and the American Centrifuge Plant in Piketon, Ohio.

“Some of those affected have been reassigned within B&W,” Mills said. “We have also provided assistance by way of job fairs and workshops to update resumes.”

Meanwhile, USEC has notified a small group of its Oak Ridge employees who worked on manufacturing activities that they would be laid off, Communications Manager Jeremy Derryberry said Tuesday. Several were transferred to other parts of the centrifuge program. [Read more…]
