KNOXVILLE—An ASM International Materials Camp supported by the University of Tennessee, Knoxville, Department of Materials Science and Engineering and scientists at CNS Y-12 National Security Complex is giving local students the chance to study debris from the space shuttle Columbia, with an eye on improving materials used in space flight.
"This is a great opportunity for local kids to get involved with materials science and see how it affects a lot of different disciplines," said Steve Dekanich, senior metallurgist at CNS Y-12 and the leader of this year's camp. "People can tend to focus on the really specialized things that materials science studies, but the reality is that it plays a part in many things that people don't realize, from energy to design."
Dekanich recalled how he met NASA's Steve McDanels at a conference in Hawaii, with the two hitting it off immediately. McDanels, who heads up NASA's materials science division at Kennedy Space Center, has spent years doing studies and analysis for the agency, including work related to the shuttles, the International Space Station and various hardware. He offered Dekanich the chance to have his campers study NASA debris for the first time in 2006, with the offer being gladly accepted.
"He's a big proponent of materials science in general and of this camp specifically," said Dekanich. "He's an advocate for science education, something we definitely welcome. It's good to see an emphasis starting to be made for science-related education once again, particularly for area students."
Though past years have seen students come from as far away as Washington, this year's camp will be made up of four teams of students drawn from East Tennessee high schools. Each team will have one particular part of the shuttle to analyze, with the goal of being able to tell how various reentry forces affected the part as well as how future design changes might mitigate that damage.
In addition to taking part in those study sessions, students will see a comprehensive presentation of the Columbia disaster from McDanels, videoconference with recently returned astronaut and UT alumnus Barry Wilmore, and tour the engineering buildings and labs at UT. "This is another example of how well UT and labs like the ones at CNS Y-12 and Oak Ridge National Laboratory can work together to benefit students and science," said Dekanich. "Those partnerships are important."
That partnership between UT and CNS Y-12 is as strong as ever, having been recently renewed at a December ceremony featuring UT Knoxville Chancellor Jimmy G. Cheek and CNS President and CEO Jim Haynes. The agreement calls for the two to work together to help collaborate in areas ranging from joint research to analyzing business operations and pushing more technologies into the private sector, all while making the country more secure.

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, Knoxville, could help pave the way.
Doctoral candidate Louis Santodonato (below), along with his adviser, Professor Peter Liaw (above), 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.
"Alloy specimens were laser-heated to the molten phase and solidified in situ during neutron scattering experiments," said Santodonato. "We did this in order to observe the atomic mixing trends and compare them to theoretcial simulations."
The full array of experiments included neutron and sychrotron X-ray scattering, electron microscopy and atom-probe tomography. Their work is crucial for engineering the next wave of alloys.
Breaking through the current stumbling blocks could make it easier to produce alloys that maintain strength at high temperatures, resist corrosion and exhibit certain levels of toughness.
"Because of their strength and stability at elevated temperatures, high-entropy alloys have potential applications in extreme environments," said Santodonato. "This could include things such as nuclear power plants, aircraft, casting dies and machine tooling."
Work was conducted at Oak Ridge National Laboratory's Spallation Neutron Source and Center for Nanophase Materials Sciences in addition to UT.

Dr. Lino Costa, Research Assistant Professor of Materials Science and Engineering at the University of Tennessee Space Institute, recently presented eight lectures on Laser Materials Processing at the Northwestern Polytechnical University (NPU), located in Xi'an, Shaanxi Province, People's Republic of China.
Professors Weiping He and Lei Lei, of NPU, invited Costa to give the series of lectures as part of the "Graduate courses in English" program. The lectures covered the following topics: Laser Marking, Laser Induced Surface Improvement (LISI), Laser Additive Manufacturing, Femtosecond Laser Machining, and Modeling of Laser Materials Processing. During the visit to NPU (6-19 January 2015), Costa also toured the labs of Professors He and Lei, where graduate students develop various part marking techniques and investigate multiple aspects of part marking technology. "In addition to laser marking and laser materials processing in general, NPU graduate students were also very interested in talking about all aspects of culture that bond east and west, from sports and music, to cinema and food! This visit to China was a truly wonderful opportunity for me, and I was very touched by the hospitality of NPU", said Costa.
Established in 1957, NPU is a Public University with two campuses (Youyi and Changan), 16 academic schools, offering 62 undergraduate programs, 122 postgraduate programs, 69 doctoral programs, and 16 postdoctoral programs. At present, NPU has over 26 thousand students in total, of which more than 14 thousand are undergraduates, and more than 3500 faculty. NPU is located in the ancient capital city of Xi'an, known as Chang'an in ancient times. As the starting point of the Silk Road, this city served as capital of China, for the Zhou, Qin, Han, and Tang dynasties, for a thousand years. Present day Xi'an offers visitor many historical sites, such as the Terracotta Warriors, the Huaqing Palace, the Xi'an City Wall, and the Giant Wild Goose Pagoda, as well as many contemporary points of interest like the Shaanxi History Museum and the Xi'an musical fountain (the largest in Asia).

KNOXVILLE—Seven students from the University of Tennessee, Knoxville, College of Engineering's Department of Chemical and Biomolecular Engineering and Department of Materials Science and Engineering recently took part in the undergraduate poster competition of the American Institute of Chemical Engineers conference in Atlanta.
The seven—seniors Aston Thompson, Christian Wilson, Chris Bruneau and Chris Ludtka and sophomores Mary McBride and Melanie Lindsey from CBE and sophomore Samantha Medina of MSE—are all part of the Zawodzinski Group, a group dedicated to electrochemical and energy storage research run by Governor's Chair Thomas Zawodzinski.
"Being chosen to take part in such a prestigious event is a real honor for our students and a good reflection on our departments" said Gabriel A. Goenaga, senior research associate in the Zawodzinski Group. "We encourage students to go to conferences, giving them the opportunity to display their research among some of their best and brightest peers.
"It is a great opportunity and good experience for their future careers."
The students used research that they have worked on under Zawodzinski, a professor in the Department of Chemical and Biomolecular Engineering, as the basis for their respective posters in the competition.
All told, more than 400 posters were presented at the conference, with UT having a strong showing.
Ludtka took home second place in Fuels, Petrochemicals and Energy II and the Undergraduate Presentation Award from AIChE industry partner Wood Group Mustang, Inc., while Lindsey (Fuels, Petrochemicals and Energy I), Wilson (Fuels, Petrochemicals and Energy II) and Bruneau (Catalysis and Reaction Engineering II) each took home third places finishes.
"We're really pleased for them to get that level of recognition while representing our university," said Goenaga. "To have that many high finishes from one research group is confirmation for both our students and our research group."
The Tennessee Solar Conversion and Storage using Outreach, Research and Education—or TN-SCORE—program, of which Zawodzinski is the Thrust II leader, made the trip and poster presentations possible.
At the end of the summer of 2014, the Center for Materials Processing (CMP) hosted a poster competition for undergraduate researchers. The winners of this internal poster competition were awarded travel expenses to participate in the 6th annual Louisiana State University (LSU) Undergraduate Research Conference (URC), "Excite/Explore/Experiment" held on October 31st.
The four students traveling were Karson Stone (sophomore, mechanical engineering), Jesse Johnson (sophomore, materials science and engineering), Maverick Echivarre (senior, materials science and engineering), and Christopher Hobbs (senior, materials science and engineering) along with Dr. Michael Koehler (Undergraduate Research Coordinator for the CMP). Ms. Stone and Mr. Johnson were placed in the Level 1 competition category reserved for 1st year researchers, while Mr. Echivarre and Mr. Hobbs were placed in the Level 2 category reserved for students who have been performing research for 3+ semesters.
Christopher Hobbs (pictured above) walked away with 1st place in the Technology & Engineering category and a monetary award for the poster "Numerical Modeling and Furnace Augmentation for Improved Growth of Large-Diameter Scintillators". Mr. Hobbs is an undergraduate research assistant at the Scintillator Materials Research Center (SMRC) and the Department of Homeland Security supports his research.

Governor's Chair Ramamoorthy Ramesh and professors Matthew Mench and David Mandrus were recently named to the "World's Most Influential Scientific Minds: 2014″ list by Thomson Reuters news service.
"This is a tremendous personal honor for all three of them, and also a strong validation of some of the things that we have going on here in the College of Engineering at Tennessee," said Wayne Davis, dean of the college.
To compile the list, Reuters studied research and releases across the globe and measured the total number of times that other researchers, professors, and students cited the material in their own findings.
Rather than just basing their result on which people had been cited the most overall, Reuters looked at which individual papers within the results had been cited the highest number of times.
Those findings placed Ramesh, Mench, and Mandrus in the top 1 percent of all research scientists across the world.
"For them to be on the list itself is nice enough, but for it to be based on the respect that others in their fields have for them—for their peers to so often cite them as leaders—underscores the sort of people we have on our faculty here," said Davis.
