Fifteen high school students and one college freshman recently got up close and personal with lab equipment worth nearly a half-million dollars at the ASM International Materials Camp. During the weeklong camp, students performed failure analyses on prosthetic implants including a hip prosthesis, pelvic clamps, a tibial nail, and tibial component. An area surgeon provided the sterilized implants, along with X-rays showing the implants before they were removed from patients.

The ASM Materials Camp is organized and sponsored by Y-12 National Security Complex, Oak Ridge National Laboratory, Tech 20/20, and the University of Tennessee in Knoxville. Steve Dekanich, an engineer in B&W Y-12’s Quality Assurance, is the camp co-chairman. [Read more…]

UT report: Economy shows signs of strength, finds ‘firm footing’

KNOXVILLE—Falling unemployment rates, an increase in vehicle sales, and a long-awaited rebound in the residential housing market are all indications that the national and state economies are making a comeback.

Despite sequestration of federal spending and a payroll tax increase that have slowed consumer spending, the economy is poised for strong growth in both 2014 and 2015, according to the spring 2013 Tennessee Business and Economic Outlook released Wednesday.

The study, prepared by the Center for Business and Economic Research, or CBER, at the University of Tennessee in Knoxville, predicts the trajectory of the state and national economies by examining many economic and fiscal factors and trends. [Read more…]

Theoretically twice as fast, Chinese supercomputer could bump Titan from No. 1 spot

A new Chinese supercomputer is theoretically twice as fast as the Titan supercomputer at Oak Ridge National Laboratory, and it could bump Titan from the No. 1 spot on the Top 500 list that will come out on June 17, one of the co-authors of the list said Wednesday.

Titan, which reached the No. 1 spot on the semiannual Top 500 list in November, has a theoretical peak of 27 petaflops, or roughly 27,000 trillion calculations per second.

The Chinese supercomputer, Tianhe-2, also known as TH-2 or Milkyway-2, has a theoretical peak of 54.9 petaflops. It also has about twice as much memory as the Titan system, said Jack Dongarra, a Top 500 co-author, University of Tennessee faculty member, and distinguished research staff member in ORNL’s Computer Science and Mathematics Division.

KNOXVILLE—Despite satellite images that show vast networks of channels, past Mars rover missions have shown limited evidence for flowing water on Mars.

Now, rocks analyzed by NASA’s Mars Curiosity Rover team, including Linda Kah, associate professor of earth and planetary sciences at the University of Tennessee in Knoxville, provide solid evidence that Mars had rivers or streams. This suggests that the environment was drastically different than today’s cold and dry conditions, with the potential to support life.

A paper on the team’s findings is published in this week’s edition of Science magazine. [Read more…]

UT, Y-12, Stanley Healthcare work to cut down on patient wait times

KNOXVILLE—Most people have experienced a long wait to see a doctor. Technology being developed through a new collaboration between the University of Tennessee in Knoxville, Y-12 National Security Complex, and Stanley Healthcare aims to cut down on wait times.

The three entities are developing an intelligent interactive dashboard that crunches data in real time to help managers determine how best to administer flow.

An official signing of a cooperative research and development agreement was signed during the Tennessee Valley Corridor’s National Technology Summit on Wednesday evening at the Y-12 National Security Complex’s New Hope Center in Oak Ridge. [Read more…]

Oak Ridge City Council member Trina Baughn has proposed that the city sell Centennial Golf Course, and terminate the lease agreement with the Chamber of Commerce and sell the property.

Those proposals would convert city-owned assets into taxable properties, Baughn said.

Baughn has also asked the seven-member Council to consider setting up a team that could negotiate voluntary payment-in-lieu-of-taxes agreements with tax-exempt organizations that “are most able to afford paying for city services that are currently paid for by the taxpayer.” Those organizations could include Methodist Medical Center of Oak Ridge, Oak Ridge Utility District, Tech 2020, Roane State Community College, and the University of Tennessee, Baughn said in a May 5 e-mail to Oak Ridge City Manager Mark Watson and City Clerk Diana Stanley.

Materials science and physics research led by early career Oak Ridge National Laboratory scientists received a boost this week from the U.S. Department of Energy’s Office of Science Early Career Research Program.

The program, now in its fourth year, is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during crucial early career years when many scientists do their most formative work. This year’s 61 awardees were selected from a pool of 770 university- and national laboratory-based applicants.

“This highly competitive program is a well-deserved recognition for early-career scientists who are launching their own research programs,” ORNL Director Thom Mason said. “We are delighted that four of this year’s awards are going to researchers associated with ORNL.” [Read more…]
