A company that manufactures high-purity metal powders and super alloys is moving its operations to Oak Ridge from Toronto, Canada, and investing $313 million here and creating 620 jobs, officials said Friday.

CVMR, which has operations in 18 countries, will use the former Theragenics building at Horizon Center in west Oak Ridge for its headquarters and research and development. The company closed on that building, which is on 21 acres, on Friday, but executives declined to disclose the sale price.

The first employee was hired Thursday, said Kamran Khozan, chairman and chief executive officer of CVMR (USA) Incorporated.

The company could expand that 65,000-square-foot building; infrastructure that is already in place allows it to be doubled. The company could put 218 people to work right away in its new headquarters and add 402 high-paying manufacturing jobs later, a state official said.

“I can promise you that this is the start of a wave,” said Randy Boyd, the new commissioner of Tennessee Economic and Community Development. [Read more…]

Friction Release

Researchers used electricity and water to control friction levels on ionic surfaces at the nanoscale. As water forms around the nanoscale electrode, it allows for further penetration into the sample surface, thereby increasing or decreasing friction. (Image courtesy ORNL)

Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.

The research, which demonstrates a new physical effect, was undertaken at the Center for Nanophase Materials Sciences, a DOE Office of Science User Facility at ORNL, and is published in the journal Scientific Reports.

“Our finding can have a significant technological impact on applications for both macroscopic and nanoscale devices,” said lead author Evgheni Strelcov. “Decreasing or increasing nanoscale friction at will and thus controlling mechanical energy losses and wear of a microelectromechanical system’s parts has enormous implications for applied energy research and opens a new vista for fundamental science studies.” [Read more…]

KNOXVILLE—One of the key holdups in the march toward more efficient sustainable energy could soon be answered, thanks in part to researchers at the University of Tennessee in Knoxville.

The College of Engineering’s Alexander Papandrew and Gerd Duscher are part of a broader Oak Ridge National Laboratory-led team that recently received a $2.75 million U.S. Department of Energy grant for work on improving fuel cells, $1.4 million of which went to their project.

The basic premise of their work is to find a far more efficient way to turn chemical energy—in this case natural gas—into electrical energy. [Read more…]

UT-Battelle, the contractor that operates Oak Ridge National Laboratory, has added another six months to an agreement being used to develop new uranium-enrichment technology through operations in Oak Ridge, Tennessee, and Piketon, Ohio.

The six-month extension was announced Friday by Centrus Energy Corporation, formerly known as USEC. UT-Battelle has exercised its option to extend the American Centrifuge Technology Demonstration and Operations Agreement, or ACTDO Agreement, by six months from March 31 to September 30, 2015, Centrus said.

ORNL had previously exercised an option to extend the agreement through March 31, 2015.

The six-month extension allows the continued demonstration and operation of the only uranium enrichment technology in the United States, Centrus said in a press release. [Read more…]

Researchers at Oak Ridge National Laboratory have developed a population distribution model that provides unprecedented county-level predictions of where people will live in the United States in the coming decades.

Initially developed to assist in the siting of new energy infrastructure, the team’s model has a broad range of implications from urban planning to climate change adaptation. The study is published in the journal Proceedings of the National Academy of Sciences.

“We do a census every 10 years because those data help us do long-term socioeconomic planning,” said Budhendra Bhaduri, who leads ORNL’s Geographic Information Science and Technology group. “Population projection numbers are important, but many pressing societal needs also require an understanding of where people are going to be. This has always been a challenge; we’ve never had a good method to make future projections spatially explicit.” [Read more…]

HARDIN VALLEY—It was a once-in-a lifetime opportunity for some, a chance to shake hands with the president of the United States of America or wave at his heavily guarded motorcade as it passed by on a local roadway.

For others, it was a chance to hear about a presidential proposal modeled after a Tennessee program that would make the first two years of community college free to students who maintain at least a 2.5 grade point average. That proposal, officially announced at Pellissippi State Community College in Hardin Valley on Friday, expands on the 20th century idea that all children in the United States are entitled to a public education. In the 21st century economy, the White House said, 12 years of school is no longer enough.

For a much-smaller group, Friday’s visit by President Barack Obama, Vice President Joe Biden, and his wife Jill Biden offered an opportunity to hear an in-person announcement of a new advanced manufacturing hub, the country’s fifth, that will be led by the University of Tennessee in Knoxville and have Oak Ridge National Laboratory as a founding partner. That announcement at Techmer PM in Clinton was highlighted by a 3-D printed carbon fiber replica of a Shelby Cobra that the president joked about receiving for his birthday. [Read more…]
