KNOXVILLE—High-entropy alloys—substances constructed with equivalent quantities of five or more metals—might hold the key to future manufacturing and construction, and two researchers from the University of Tennessee in Knoxville could help pave the way.

Doctoral candidate Louis Santodonato, along with his adviser Professor Peter Liaw, both in materials science, did an extensive study into this class of materials, which are considerably lighter and less prone to fracture, corrosion, and oxidation than conventional alloys.

The pair used various methods to observe and model the atomic mixing behavior of high-entropy alloys, work that was picked up by the prestigious journal Nature Communications. [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…]

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.

KNOXVILLE—President Obama’s announcement on Friday that the University of Tennessee in Knoxville would be the lead institution in a $259 million advanced composites manufacturing project known as the Institute for Advanced Composites Manufacturing Innovation, or IACMI, was met with applause, but also a few questions.

Many wondered what advanced composites manufacturing really means, why the UT-led consortium was selected, and what the impact for the area might be.

Here are some answers.

What is IACMI?

IACMI is the newest federally funded institute for manufacturing innovation. Its focus is on advancing innovation in the manufacturing of composites used in automobiles, wind turbines, and compressed gas storage tanks. [Read more…]

KNOXVILLE—For many, the end of football season usually means attention turns to basketball, but for more than 400 budding scientists and engineers who came to the University of Tennessee in Knoxville on Saturday it marks the start of something else: robot season.

FIRST Robotics kicked off its 2015 game, Recycle Rush, with a live reveal broadcast online to teams around the world, including 29 teams who gathered at Cox Auditorium on the UT campus.

“Saturday marks the first time that any of the teams get to see the challenge of this year’s game,” said L.J. Robinson, Tennessee’s regional director of FIRST (For Inspiration and Recognition of Science and Technology). “The kickoff event is a big deal in its own right, with gatherings held around the world to watch the announcement.

“Certainly, it’s an exciting moment for those new to the competition.” [Read more…]

Former chancellor, astronaut also honored

KNOXVILLE—In 1847, a course offering studies in mechanical philosophies and mechanics appeared in what was then East Tennessee University.

Now, almost 170 years later, the school is the University of Tennessee in Knoxville, and the course has grown into the College of Engineering’s Department of Mechanical, Aerospace and Biomedical Engineering, or MABE, two-thirds of which would have been considered science fiction to those many years ago.

Now, the department is calling upon that legacy as it prepares to open its Hall of Fame.

The honor of being in the inaugural class belongs to a chancellor, an astronaut, an automotive pioneer, and a person who had a longtime presence in various Oak Ridge facilities. [Read more…]

UT study: Percentage of uninsured in Tennessee at its lowest in a decade

KNOXVILLE—The percentage of uninsured Tennesseans is at its lowest rate in a decade, according to a report released Monday by the University of Tennessee in Knoxville.

The report shows that 7.2 percent of Tennessee’s 6.5 million residents are uninsured, a 25 percent decrease from last year. The report also shows that 2.4 percent of children in the state are without insurance, a 35 percent decrease from last year.

The findings are included in “The Impact of TennCare: A Survey of Recipients 2014,” prepared by UT’s Center for Business and Economic Research, or CBER. The report’s authors are Angela Thacker, CBER research associate, and LeAnn Luna, CBER associate professor.

The declines coincide with the establishment of the Health Insurance Marketplace, which was put into place in early 2014 through the Affordable Care Act. The act also has had an impact on the state’s Medicaid program, TennCare, which has experienced the third highest new enrollment in its 20-year history. [Read more…]

Thanks + Giving: UT researcher says gratitude may be a key to happiness

KNOXVILLE—’Tis the season to be grateful. And, being grateful for what you have may be the key to happiness, according to research by a professor at the University of Tennessee in Knoxville.

Jeff Larsen, associate professor of psychology, and Amie McKibban of the University of Southern Indiana investigated whether the maxim “it’s more important to want what you have than to have what you want” is true.

He asked college students if they possessed 52 different material items, such as a car, a stereo, or a bed. They were then asked to rate how much they wanted the items they had and how much they wanted the items they didn’t have. Larsen calculated the extent to which the students wanted what they have and have what they want.

The result? People who want more of what they have tend to be happier. [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…]
