KNOXVILLE—Graduate teaching associate Laura Lemon found herself in an interesting spot at last week’s Medal of Honor Town Hall at the University of Tennessee in Knoxville.

On one side of her sat her public relations students, eagerly taking notes to write a press release about the event. On the other side sat her father, Medal of Honor recipient Peter Lemon.

A doctoral student, Laura Lemon said her involvement with UT’s Medal of Honor Project began last year when she went to Assistant Professor Nick Geidner’s office for help in one of his classes that she was taking.

Geidner directs the Medal of Honor Project, which is an award-winning service-learning collaboration between UT’s School of Journalism and Electronic Media and the 2014 Medal of Honor Convention, held last week in Knoxville. (It included a Town Hall Forum in Oak Ridge on Friday.) Through the project, students produced written, audio, and video pieces related to the convention. Although the convention is over, the project will continue sharing stories about Medal of Honor recipients and become a model for other universities that want to partner with future conventions.

KNOXVILLE—Sticker shock at the gas pump could soon be a thing of the past thanks to research being conducted by Oak Ridge National Laboratory and the University of Tennessee in Knoxville.

Among the key components in processing fuels, particularly bio-friendly ones, are the membranes that aid in the process of separating unwanted compositions such as water from the fuel or hydrocarbon from aqueous phase.

“We can help wallets and help profits at the same time,” said Michael Hu, a joint faculty member of ORNL and the College of Engineering’s Department of Chemical and Biomolecular Engineering. “If we can improve that separation process it will mean a reduction in cost to make, a reduction in cost to supply, and a reduction in cost to buy.”

The breakthrough technology being brought to life by the research team combines nanotextured pores with superhydrophobic or superhydrophillic—or, in plain terms, super water-repulsing and water-attracting—substances. [Read more…]

KNOXVILLE—For more than seven decades, the University of Tennessee in Knoxville and Oak Ridge National Laboratory have forged special connections in a number of key areas, perhaps none stronger than the personnel that the two share.

That particular bond was on display recently when members of UT’s Office of Professional Practice office visited the facilities at ORNL, meeting more than 60 engineering students involved in summer internships at the lab.

Todd Reeves, director of the office, addressed the College of Engineering students and shared his thoughts about the importance of the work they are doing for ORNL and on leaving a good impression of themselves and their attitude.

“We talked about how special it is for them to be working in such a high-profile facility, and that it was key for them to do their best every day,” Reeves said. “More than that, we encouraged them to be enthusiastic and positive as they went about their work because it shapes the impression their managers have on them.” [Read more…]

KNOXVILLE—For some, getting on the Internet can be a blast.

Now, thanks to the Bandwidth for Leadership in Advancing Science and Technology project—known as BLAST—it can also be faster for computer users at the University of Tennessee in Knoxville.

A lot faster.

“This is quite an accomplishment, for both UT and for the researchers who use the network,” said Victor Hazlewood, chief operating officer at the Joint Institute for Computational Sciences and the National Science Foundation’s principal investigator on BLAST. “This really positions UT well to continue to be at the forefront of innovation.”

The upgrade, completed May 25, is a combined effort between JICS and UT’s Office of Information Technology and makes it possible for UT users to make use of Internet speeds up to 100 gigabits per second. JICS is an institute of UT and Oak Ridge National Laboratory. [Read more…]

KNOXVILLE—Researchers at the University of Tennessee and Oak Ridge National Laboratory are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere.

Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes—called bioscavengers—so they work more efficiently against chemical weapons. The work is a joint effort between scientists at UT, ORNL, and a French national laboratory in Grenoble. Their study was published recently in the Journal of Physical Chemistry.

Nerve agents, such as sarin, are among the most highly toxic chemical weapons. The study focuses on engineering enzymes that catalyze the hydrolysis of nerve agents as a prophylactic approach to diminishing their toxic effects. [Read more…]

KNOXVILLE—The Center for Transportation Research will give area high school students a behind-the-scenes look at public transit in Knoxville and Atlanta when it hosts its first Transit Camp July 29-31 at the University of Tennessee in Knoxville.

Open to high school sophomores, juniors, and seniors, the camp is designed to spark interest in STEM—science, technology, engineering, and math—and to showcase focus areas, such as public transit, that might not readily come to mind when engineering and technology are discussed.

“The goal of this camp is to expose area students to the types of transit careers available, as well as becoming more aware of the reach of transit,” according to Tammy Enix from CTR.

Through the camp, the center—part of the College of Engineering at UT—will help students learn about how modern transportation systems rely on everything from designers and graphic artists to planners and maintenance officials. [Read more…]
