CMP Poster Competition Sends Students to LSU Conference

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.

Improving Plant-based Battery with Neutrons and Simulations

09.18.14 Researchers at ORNL and the University of Tennessee are studying the structure of plant-based battery materials by combining neutron experiments and supercomputer simulations.
Initial testing of the lignin-derived battery showed promising results in terms of capacity and cycling stability, but the researchers wanted to understand how and why the material behaved so differently from other graphites. Rios began collaborating with the University of Tennessee's Computational Materials Group, led by David Keffer, to further examine the fibers' structure and behavior.
"There aren't many techniques we can use to study these unique materials made of crystalline domains within an amorphous matrix," said UT's Nicholas McNutt, a graduate student in Keffer's group. "We wanted to tie together some of Oak Ridge National Lab's best resources -- neutrons and computers -- and see what we could do."
The team ran neutron scattering experiments at ORNL's Spallation Neutron Source (SNS) to analyze how lignin-based fiber samples reacted with lithium. The SNS is a DOE Office of Science user facility that provides the most intense pulsed neutron beams in the world for scientific research and industrial development.
Using the neutron data, the team developed computational models and ran simulations on supercomputers including the Oak Ridge Leadership Computing Facility's (OLCF) Titan, supported by DOE's Office of Science, and UT's Kraken, supported by the National Science Foundation. The team detailed its approach in the Journal of Applied Crystallography.
"Our models allow us to take experimental neutron scattering data and predict things about the local atomic structure," McNutt said. "We are using computation to understand experimental data in a way that you couldn't do before."
The initial combination of neutron experiments and simulation gave the UT-ORNL team a first glimpse into how the material's structure affects its overall performance. Now that they have confirmed their model's accuracy, the researchers plan on applying the technique to how the material's structure changes with and without added lithium, mimicking the charging and discharging cycles of a real battery.

New ion beam materials laboratory for materials modification and irradiation effects research

ABSTRACT: "A new multifunctional ion beam materials laboratory (IBML) has been established at the University of Tennessee, in partnership with Oak Ridge National Laboratory. The IBML is currently equipped with two ion sources, a 3 MV tandem accelerator, three beamlines and three endstations. The IBML is primarily dedicated to fundamental research on ion–solid interaction, ion beam analysis, ion beam modification, and other basic and applied research on irradiation effects in a wide range of materials. An overview of the IBML facility is provided, and experimental results are reported to demonstrate the specific capabilities."

Three Engineering Professors on "World's Most Influential" List

From left to right: Governor's Chair Ramamoorthy Ramesh;
Matthew Mench, head of the Department of Mechanical, Aerospace,
and Biomedical Engineering; and Professor David Mandrus.


Since having your work recognized by your peers has long been considered a top honor for those in higher education, a trio of College of Engineering professors recently became academic all-stars. 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.

Along with being a Governor's Chair, Ramesh is the deputy director for science and technology at Oak Ridge National Laboratory in addition to his role in the Department of Materials Science and Engineering at UT—where Mandrus is also a professor—while Mench is the head of and the Condra Chair of Excellence in the Department of Mechanical, Aerospace, and Biomedical Engineering.
Ramesh is an expert in solar nanotechnology, while Mench studies electrochemical power storage, transport, and conversion, and Mandrus is a leader in developing breakthroughs that lead to ever-smaller, more efficient electronics.

Yang Tong receives Acta Student Award

Yang Tong

Yang Tong, a graduate student in the Department of Materials Science and Engineering, has received the prestigious Acta Student Award for 2013. This award honors the best student contribution to Scripta Materialia in 2013. The competition is very tough for this award, and only best papers are chosen. Tong also contributed to Acta Materialia in 2013. Both Scripta and Acta are high impact journals. Tong's contribution to Scripta has gained a lot of attention in the metallic glass community and has been very popular on the Elsevier website.

Theory and experiments met at SMRC labs

Students from MSE 250 (Introduction to Materials Kinetics and Transport Phenomena) had the opportunity to connect the theory learned in class to the actual experiments at the Scintillation Materials Research Center (SMRC). Dr. Mariya Zhuravleva and Mrs. Merry Koschan kindly showed the MSE 250 undergraduates how Czochralski and Bridgman methods were used to grow single crystals, while Dr. Yanfei Gao, the instructor of MSE 250, had taught the underlying theories in class. The abstract concepts of forced and natural convection, thermocapillary convection, and motion of solid/liquid interface became better understood by the students, as shown by their smiling faces.
