Ellen Smith, who served on Oak Ridge City Council from 2007 to 2012, has announced that she is a candidate for City Council in the November 4 election.

Smith is a 33-year resident of Oak Ridge who describes herself as “an Oak Ridger by choice.” As newcomers to East Tennessee in 1981, she and her husband Rich Norby looked around the area and then chose to buy in Oak Ridge and make this city their home, a press release said.

Both have made their careers at the Oak Ridge National Laboratory, where Ellen is a research staff scientist in the Environmental Sciences Division and Rich is a corporate fellow in the Environmental Sciences Division and Climate Change Science Institute. Their adult son Karl was born here and attended school at Linden Elementary School, Robertsville Middle School, and Oak Ridge High School.

Smith said she decided to run for City Council this year after many citizens from diverse sectors of the city urged her to do so, the press release said. People tell her they value her knowledge of Oak Ridge, its history, and city government; her thoughtful analysis of issues and proposed solutions; and her responsiveness to citizens who contacted her with concerns, the release said. Smith said she is committed to working for the community and all of its citizens. [Read more…]

Robertsville Middle School

Robertsville Middle School in Oak Ridge is one of three additional schools in East Tennessee that have opened STEM Scouts labs.

Robertsville Middle School in Oak Ridge is one of three other schools in East Tennessee that have opened STEM Scouts Labs. The other two new participants are Karns Middle School and Stanford Eisenberg Knoxville Jewish Day School.

That brings the total number of STEM Scouts Labs in the area to seven, a press release said. Oak Ridge High School and Clayton-­Bradley STEM Academy already have STEM Scouts Labs.

STEM Scouts is a co-­ed after-­school program by the Boy Scouts of America that uses hands-­on learning to show youth from elementary through high school how to apply STEM (science, technology, engineering, math) in their everyday lives and encourages them to develop those experiences into a future career, the press release said. The program uses the Scout Oath and Scout Law as its cornerstone.

“We are very happy to see STEM Scouts growing, “ said April McMillan, national co-director of STEM programs for the Boy Scouts of America. “We are the first in the nation to test this program, so we are pleased to see it taking off like this. We’ve had very positive feedback from students, teachers, and parents. We hope to open several more labs before the end of the year.” [Read more…]

KNOXVILLE—The only “car” that most people associate with printers is a “car-tridge” of ink, but that may soon change thanks in part to several students at the University of Tennessee in Knoxville.

UT, Oak Ridge National Laboratory, Local Motors, Cincinnati Incorporated, and Oak Ridge Associated Universities teamed up to print a working, drivable car over the weekend at the International Manufacturing Technology Show in Chicago.

The Strati 3D, officially produced by Local Motors, which has an office on Market Square in Knoxville, highlighted the show and placed what sounds like a product of science fiction firmly in the realm of reality.

“This brand-new process disrupts the manufacturing status quo,” said John B. Rogers Jr., chief executive officer of Local Motors. “It changes the consumer experience and proves that a car can be born in an entirely different way.” [Read more…]

KNOXVILLE—An international research team led by an assistant professor at the University of Tennessee in Knoxville has received a grant to help with work involving a key component of nuclear reactors.

The U.S. Department of Energy grant is worth $800,000 over three years, and it has been awarded to UT Assistant Professor Haixuan Xu. It’s part of the Nuclear Energy University Programs funding and will be used to work on a pair of particular steel alloys, a press release said.

“Getting support on this will allow us to investigate and understand the defect evolution in these materials,” said Xu, of the UT Department of Materials Science and Engineering. “What we hope to gain is fundamental insight into the effects of radiation on the alloys so that we can better predict and detect how they will break down over time and adjust the materials accordingly.”

The alloys in question would be used in sodium-cooled reactors. Xu’s research is important because little is known about how the materials stand up to high levels of radiation over time. [Read more…]

The High Flux Isotope Reactor, or HFIR, now in its 48th year of providing neutrons for research and isotope production at Oak Ridge National Laboratory, has been designated a Nuclear Historic Landmark by the American Nuclear Society.

“This designation from the ANS recognizes HFIR’s role in the history of the nuclear age, but it also speaks to the excellence of its design and operation,” ORNL Director Thom Mason said. “HFIR remains one of the world’s most capable reactor-based neutron science, radioisotope production, and materials irradiation facilities, and we expect that to continue for many years.”

The designation was proposed by the ANS honors and awards committee and approved on initial ballot by the board of directors.

“The ANS Nuclear Historic Landmark signifies that a nuclear facility has played an important role in nuclear science and engineering,” ANS President Michaele C. Brady Raap said. “HFIR, with its preeminent role in isotope production and neutron science, certainly meets that criteria.”

The reactor was conceived in the late 1950s as a production reactor to meet anticipated demand for transuranic isotopes (“heavy” elements such as plutonium and curium). HFIR today is a U.S. Department of Energy Office of Science User Facility and one of the world’s sole sources of the radioisotope californium-252, used in industry and medicine. ORNL is a DOE lab.

Recycled Tire Battery Schematics

Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at Oak Ridge National Laboratory.

By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries. An anode is a negatively charged electrode used as a host for storing lithium during charging.

The method, outlined in a paper published in the journal RSC Advances, has numerous advantages over conventional approaches to making anodes for lithium-ion batteries.

“Using waste tires for products such as energy storage is very attractive not only from the carbon materials recovery perspective but also for controlling environmental hazards caused by waste tire stock piles,” Paranthaman said.

The ORNL technique uses a proprietary pretreatment to recover pyrolytic carbon black material, which is similar to graphite but man-made. When used in anodes of lithium-ion batteries, researchers produced a small, laboratory-scale battery with a reversible capacity that is higher than what is possible with commercial graphite materials.

ORNL scientists uncover clues to role of magnetism in iron-based superconductors

Magnetism of Iron-based Superconductors

New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at Oak Ridge National Laboratory and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism.

The study published in Advanced Materials provides experimental evidence that local magnetic fluctuations can influence the performance of iron-based superconductors, which transmit electric current without resistance at relatively high temperatures.

“In the past, everyone thought that magnetism and superconductivity could not coexist,” said ORNL’s Claudia Cantoni, the study’s first author. “The whole idea of superconductors is that they expel magnetic fields. But in reality things are more complicated.”

Superconductivity is strongly suppressed by the presence of long-range magnetism—where atoms align their magnetic moments over large volumes—but the ORNL study suggests that rapid fluctuations of local magnetic moments have a different effect. Not only does localized magnetism exist, but it is also correlated with a high critical temperature, the point at which the material becomes superconducting. [Read more…]

Many projects are happening in Oak Ridge at the present time. Our city does not slow down and is affected by issues at the state, federal, and local levels.

As your city manager, I am concentrating on matters such as the implementation of EPA sewer requirements on a tight timeframe, creation of a national park, development of a new mall, and installation of a new dispatch center.

Among its many other decisions, Oak Ridge will be facing a pair of major initiatives which particularly important for our community. The American Museum of Science and Energy (AMSE), owned by the U.S. Department of Energy (DOE) and managed by Oak Ridge National Laboratory contractor UT-Battelle, is under new leadership as veteran museum director David Moore takes the helm. With this change, the DOE knows that the long-term viability of a museum is dependent upon local and regional involvement.

Recently, the AMSE Foundation and the City of Oak Ridge have been co-hosting a series of community meetings about AMSE to discuss options for developing a new operating model for the museum. Two of four public discussions have been held about this topic.

Last week, we heard from the directors of the MUSE in Knoxville, the Titanic Museum in Pigeon Forge, and the new Birthplace of Country Music Museum in Bristol to hear how today’s museums remain current and relevant to their visitors. Turnout for the first two meetings has been very encouraging; the next public meeting is scheduled for Thursday, September 25, from 6-8 p.m., when heritage tourism will be discussed. [Read more…]
