Oak Ridge National Laboratory announced this fall that Samsung Electronics has exclusively licensed a technology that can improve the performance of glass displays on smart phones, tablets, and other electronic devices.

ORNL has developed a transparent coating that repels water, carrying away dust and dirt; reduces light reflection; and resists fingerprints and smudges. The optically clear superhydrophobic film technology was the result of about three years of superhydrophobic research on glass-based coatings, ORNL said in a press release.

“The thin nanostructured layer of porous glass film enables these combined properties, making it suitable for commercial applications,” said ORNL’s Tolga Aytug, co-inventor of the technology.

To be superhydrophobic, a surface must achieve a water droplet contact angle exceeding 150 degrees. ORNL’s coating has a contact angle of between 155 and 165 degrees, so water literally bounces off, taking away dust particles, the press release said. [Read more…]

The Great Smoky Mountains, which are normally wet and hazy, had been in a particularly prolonged drought when a fire started near a popular lookout several miles from the resort town of Gatlinburg, Tennessee, just before Thanksgiving. Park officials warily watched the slowly spreading blaze, which was in nearly vertical and mostly unreachable terrain.

At the close of the holiday weekend, a weather system moved in, whipping up gale-force winds hours ahead of the rain. The wind supercharged the fire, driving eerie, thick smoke down the basin toward the town. By Monday night, the homes, resorts, and businesses surrounding Gatlinburg were in the middle of a firestorm as flames destroyed structure after structure. Downed power lines sparked separate fires.

On the evening of November 28, park and city officials reached out to firefighters in the region for support as flames engulfed entire neighborhoods. By the time quenching rains arrived, the 17,000-acre forest fire had burned 1,700 structures—many of them homes—and took 14 lives.

Firefighters from Oak Ridge National Laboratory, located about 50 miles away, were among those who answered the call. With an immediate go-ahead from the ORNL Site Office, the ORNL Fire Department, or ORNLFD, dispatched resources to assist responders in Gatlinburg and neighboring Pigeon Forge. [Read more…]

More than 80,000 people have visited the three sites of the Manhattan Project National Historical Park, which includes Oak Ridge, according to a nonprofit organization in Washington, D.C.

Besides Oak Ridge, the park includes Hanford, Washington, and Los Alamos, New Mexico.

In Oak Ridge, the Manhattan Project National Historical Park has a volunteer or ranger at the American Museum of Science and Energy in Oak Ridge when the museum is open. The park also has activities. For example, there is a program on secrecy, security, and spies at the Oak Ridge Turnpike Gatehouse in west Oak Ridge on Saturday, December 17. And the park, in partnership with the Children’s Museum of Oak Ridge, will be featuring a Parks in Focus photography exhibit during the month of December. The photography exhibit is located in the Imagination Gallery at the museum located at 461 West Outer Drive.

Also, a virtual tour of the K-25 Building can be found at the new K-25 Virtual Museum website. And from March to November, admission to AMSE includes a three-hour bus tour of the Oak Ridge Reservation, including the X-10 Graphite Reactor at Oak Ridge National Laboratory, New Bethel Church at ORNL, the visitor overlook at the East Tennessee Technology Park (former home to the K-25 gaseous diffusion building), and Y-12 New Hope History Center.

The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the U.S. Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.

“The presence of tennessine on the Periodic Table is an affirmation of our state’s standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory’s scientists and technicians,” ORNL Director Thom Mason said in a press release.

The International Union of Pure and Applied Chemistry, or IUPAC, gave its final approval to the name “tennessine” following a year-long process that began December 30, 2015, when IUPAC and the International Union of Pure and Applied Physics announced verification of the existence of the superheavy element 117. That was more than five years after scientists first reported its discovery in April 2010.

IUPAC validates the existence of newly discovered elements and approves their official names.

ORNL had several roles in the discovery, the most prominent being production of the radioisotope berkelium-249 for the search. [Read more…]

Building a new water treatment plant in Oak Ridge or rehabilitating the current one could cost between $43.1 million and $46.9 million, according to an evaluation of three alternatives prepared for the city by an engineering company. The three alternatives are show in the image above.

 

Building a new water treatment plant in Oak Ridge or renovating the current one could cost between $43.1 million and $46.9 million, according to an evaluation prepared for the city by an engineering company.

Three alternatives for renovating the existing water plant or building a new one were presented to the Oak Ridge City Council in October in an evaluation by Jacobs Engineering Group. The three options have different impacts on the raw water intake on the Clinch River in south Oak Ridge, an intermediate pump station at the Y-12 National Security Complex between the raw water intake and the existing water treatment plant, and the current 70-year-old plant, which is on Pine Ridge above Y-12.

The first alternative, which could cost $46.5 million, would rehabilitate the existing plant. It would continue to use the raw water intake, the intermediate pump station, and the water plant. It would include work at those three sites, as well as to the two underground lines that feed the water plant.

The rehabilitation would require mechanical and process equipment upgrades, pipeline replacement, electrical improvements, and slope stabilization.

The Jacobs evaluation said the building and basins at the existing plant are in good condition, and the facility works well at 8-12 million gallons per day. It has the two underground lines coming in and three going out, and two storage reservoirs on Pine Ridge, one of three million gallons and the other of four million gallons. [Read more…]

Oak Ridge National Laboratory has been awarded $3.36 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy, or ARPA-E, to develop novel control technologies for connected and automated vehicles with the goal of achieving a 20 percent improvement in vehicle energy efficiency, a press release said.

The project will focus on developing and implementing control technologies in a plug-in hybrid electric vehicle, or PHEV, to achieve the following: compute optimal routing to bypass bottlenecks, accidents, special events, and other conditions that affect traffic flow; accelerate and decelerate optimally based on traffic conditions and the state of the surrounding roads; and optimize onboard powertrain efficiency.

“This approach changes the mathematical framework of how the vehicle is controlled and optimized today,” said ORNL’s Andreas Malikopoulos, the project’s principal investigator. “With our proposed concept, the vehicle will no longer operate in isolation but will be considered as part of an integrated system, which ultimately could help increase energy efficiency and reduce greenhouse gas emissions.” [Read more…]
