Karren L. More, a researcher at Oak Ridge National Laboratory, has received the 2013 DOE Hydrogen and Fuel Cells Program R&D Award in recognition of her leadership of ORNL’s project on microstructural characterization of fuel cell materials and for her role as a subcontractor on multiple DOE-funded fuel cell research and development projects.

More’s experience with a variety of electron microscopy techniques has enabled unprecedented levels of characterization of a variety of materials used in catalysts, supports, ionomers, gas diffusion layers, and membranes. She has collaborated on numerous fuel cell durability and aging studies with other DOE national laboratories and leading manufacturers such as 3M, General Motors, Ballard, AFCC, Nissan, Nuvera, and UTC.

The Oak Ridge National Laboratory has begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.

“It might explain why we’re here at all,” said David Radford, who oversees specific ORNL activities in the Majorana Demonstrator research effort. “It could help explain why the matter that we are made of exists.”

Radford, a researcher in ORNL’s Physics Division and an expert in germanium detectors, has been delivering germanium-76 to Sanford Underground Research Laboratory in Lead, S.D., for the project. After navigating a Valentine’s Day blizzard on the first two-day drive from Oak Ridge, Radford made a second delivery in March. [Read more…]

A federal cleanup contractor in Oak Ridge is removing exterior panels known as transite panels from the last part of the K-25 Building that is still standing.

K-25 was built to enrich uranium for atomic bombs during World War II and was once the world’s largest building under one roof. It’s been unused for decades and is being torn down.

Most of the mile-long former gaseous diffusion building, located at East Tennessee Technology Park, has been demolished. About two million square feet of the U-shaped building have been removed, according to a Thursday press release from UCOR, the cleanup contractor for the U.S. Department of Energy in Oak Ridge.

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…]

ORNL analysis predicts extreme weather losses could double by 2050

By Katie Elyce Freeman

U.S. economic losses from extreme weather could at least double by 2050, according to an Oak Ridge National Laboratory analysis published this month in the online edition of the journal Global Environmental Change.

“A side effect of America’s growth has been the tendency to put more people, infrastructure and assets in harm’s way, and when a storm comes through, that increased exposure drives up economic losses,” said author Benjamin Preston, deputy director of ORNL’s Climate Change Science Institute, who studied historical data from more than 3,000 U.S. counties and used predictive modeling in the assessment. Preston works in impacts, adaptation, and vulnerability science, a field devoted to analyzing the effects of climate change on people, governments and industries. [Read more…]

Information from WYSH Radio

Students, teachers, and school administrators gathered to dedicate a new, so-called “net zero” classroom on the campus of Clinton High School on Tuesday.

The 1,150-square-foot building is powered by solar panels and is independent of the electric grid. The classroom, believed to be the first of its kind in the state, was funded by the school system as well as grants from Tennessee Valley Authority and Oak Ridge National Laboratory as well as other sponsors.
