Amal al-WahishUT’s Physicists and ORNL Engineers Collaborations Lead to a New Apparatus Design for High Temperature (up to 950 °C) Quasi-Elastic Neutron Scattering in a Controlled Gaseous Environment

Amal al-Wahish is a former student in Dr. David Mandrus' research group in the department of Material Science and Engineering. Her doctoral dissertation studied Phosphate Proton Conductors at elevated temperature using Quasi-Elastic Neutron Scattering. The operation of these proton conductors needs a sample environment running at temperatures exceeding 300 °C. At that time, the available sample environment for experiments at Backscattering Spectrometer Spallation Neutron Scattering could only accommodate temperatures well below that.

Amal had two choices: to either change her dissertation topic or design and build a new apparatus. She took up the challenge of building the apparatus. Working together with a brilliant ORNL staff (D. Armitage, N. Jalarvo , B. Hill, and R. Mills), the apparatus was built in 2011 and has been in use since that time at ORNL for the purpose of conducting quasi-elastic neutron scattering studies. It is a versatile system capable of studying neutron dynamics in situ under operational conditions similar to solid oxide fuel cells with the ability to control humid and dry gas flow under various environmental conditions and over a wide range of temperatures reaching up to 950 °C, enabling the user to measure chemical, dynamical and physical changes in situ. The setup has proven especially effective in studies of high temperature Quasi-elastic neutron scattering, where it reveals information about microscopic scale under dry and humid conditions, but the apparatus can potentially be used in many different neutron experiments with suitable sample can material.

In Fall 2015, Amal al-Wahish, David Mandrus, and their colleagues at ORNL and Berry college published an article in the journal Review of Scientific Instruments (Vol.86, Issue 9) with the title "A new apparatus design for high temperature (up to 950 °C) quasi-elastic neutron scattering in a controlled gaseous environment."

The team included Amal al-Wahish, D. Armitage, U. al-Binni, B. Hill, R. Mills, N. Jalarvo, L. Santodonato, K. W. Herwig, and D. Mandrus.

UT Materials Science Duo Advances Next Wave of Alloys

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.

Chemical, Materials Engineering Students Have Strong Showing

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.

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.

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.
