Science: ORNL researchers tune friction in ionic solids at the nanoscale

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…]

Roane State Community College’s Kirk Harris believes details save lives.

Harris, director of continuing healthcare and safety education, recently started offering a course on tactical combat casualty care/tactical emergency casualty care. The course applies lessons learned from the experiences of U.S. soldiers and the latest research on combat care in Iraq and Afghanistan to situations first responders could face.

“Unfortunately, we are seeing law enforcement incidents that are more like military combat, such as mass shootings at schools and industries,” Harris said. “We can learn a lot from the experiences of soldiers in Iraq and Afghanistan. This course brings that knowledge together.” [Read more…]

A light layer of snow dusted Oak Ridge on Tuesday morning, and schools were closed in Anderson and Roane counties.

The Anderson County Schools’ Central Office was following its bad weather procedures. The Roane County Schools’ Central Office opened one hour late.

Oak Ridge Schools opened on time.

Clinton City Schools reported that roads were clear in Clinton—”and school buildings are warm”—and schools would open on time. [Read more…]

Finding a new preschool might not happen as quickly as some would like, but the city’s school board on Monday recommended a few first steps that could have children in a new building by the 2016-2017 school year.

The main concern now: Fix the lead-based paint on the decades-old home of the Preschool on New York Avenue. That repair could cost an estimated $150,000. A remediation plan could be submitted to federal officials and Anderson County education officials by March 4.

There had been some hope that a new home for preschool students might be found as early as this August. [Read more…]

An Oliver Springs teenager riding a motorcycle was killed in a Monday morning crash with a car.

Aaron Gunter, 17, of Oliver Springs, was riding westbound on a 2005 Suzuki dirt bike on State Highway 62 near Coalfield when he was hit by a 2008 Kia Sportage at about 6:41 a.m. Monday, the Tennessee Highway Patrol said in a preliminary report.

The Kia was also traveling westbound and driven by Sharon Morton, 75, of Andersonville. [Read more…]

It’s been on the city’s wish list for decades, but city and school officials now appear closer to finding a solution to repairing or replacing the city’s preschool.

Officials said they’ve “kicked the can down the road” for years, but the discussion gained urgency after lead-based paint was found on the exterior of the 70-year-old building during a routine inspection in the spring of 2014. It could cost up to $150,000 to make repairs. Officials have characterized that as a Band-Aid or “last investment.”

“We’re going to have make a decision now, unfortunately, because of the paint,” said Keys Fillauer, Oak Ridge Board of Education chair. “The bottom line is: How are we going to pay for this?” [Read more…]

Helen Ross McNabb Veterans Housing Project

This eight-unit apartment building on Coster Road in Knoxville was built to house homeless veterans who have mental illness or a behavioral health disability. The first four veterans moved into their new apartments before Christmas. By springtime, the Helen Ross McNabb Veterans Housing Project will provide permanent apartment homes to 23 veterans, who will also receive ongoing case management.

Donation contributes to new housing and care through Helen Ross McNabb Center

Consolidated Nuclear Security’s donation of $25,000 to the Helen Ross McNabb Center’s Veterans Housing Project served as one of the final building blocks in the $1.83-million effort to provide permanent housing to homeless veterans who have mental illnesses. On December 15, the ribbon was cut on the first apartment building, and the first four homeless veterans moved into their new homes in time to celebrate Christmas.

The CNS donation helped fund the newly constructed Cedar Crossing apartment building on Coster Road in Knoxville, which provides eight one-bedroom units. The second phase of the project is rehabilitating a former apartment complex off Washington Pike that will provide another 15 apartment homes. The three-building Washington Oaks renovation is expected to be completed by March 2015. [Read more…]

Science: Warming could cause great loss of Great Barrier Reef corals

KNOXVILLE—Living corals covering Australia’s Great Barrier Reef could decline to less than 10 percent if ocean warming continues, according to a new study that explores the short- and long-term consequences of environmental changes to the reef.

The study was done by an international team of ecologists at the National Institute for Mathematical and Biological Synthesis, or NIMBioS, at the University of Tennessee in Knoxville. It is available pre-print online in the journal Ecology at http://bit.ly/1JmaLk0.

Environmental change has caused the loss of more than half the world’s reef-building corals. Coral cover, a measure of the percentage of the seafloor covered by living coral, is now just 10-20 percent worldwide. The Great Barrier Reef, once considered one of the more pristine global reef systems, has lost half its coral cover in the last 27 years. Overfishing, coastal pollution, and increased greenhouse gas emissions leading to increased temperatures and ocean acidification, as well as other human impacts, are all disrupting the delicate balance maintained in coral reef ecosystems.
