Volkswagen-Sponsored Camp Introduces Students to UT, Engineering | Knoxville, TN | June 9, 2016
From Tennessee Today:
Although the kids may be out of school for the summer, the opportunity to learn hasn’t taken a vacation.
With the Volkswagen-sponsored Engineering VOLunteers for Tenth Graders, or eVOL10, now under way at UT’s College of Engineering, students in high school and middle school are getting a chance to take a deeper look into future possibilities in science, technology, engineering, and mathematics, or STEM.
Assisted by the UTK AIChE ChemE Car Team, students were taught the engineering design process and told to design and produce a car out of small building blocks that could travel using a Baking Soda- Vinegar reaction.

Royal Academy of Engineering Selects Zawodzinski For Fellowships | United Kingdom | March 4, 2015
From TN Today:
The United Kingdom's Royal Academy of Engineering recently awarded awarded Thomas Zawodzinski, the Governor's Chair Professor in Electrical Energy Storage, and Stephen J. Paddison, the Gibson Endowed Chair in Engineering at UT, Distinguished Visiting Fellowships.
The program was established to develop capacity and facilitate collaborations by distinguished international experts with UK universities. With only three total professors from the United States being selected the previous year, having two from the same college, let alone the same department, is an amazing accomplishment.
Zawodzinski will spend part of the upcoming summer visiting the laboratory of Professor Nigel Brandon, Department of Earth Science and Engineering at Imperial College in London to continue collaborative work.

AICHE Annual National Conference | Atlanta, GA | November 12-19, 2014
From TN Today:
Seven students from the 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 sevenâ€”seniors Aston Thompson, Christian Wilson, Chris Bruneau and Chris Ludtka and sophomores Mary McBride and Melanie Lindsey from CBE and sophomore Samantha Medina of MSEâ€”are all part of the Zawodzinski Group, a group dedicated to electrochemical and energy storage research run by Governorâ€™s Chair Thomas Zawodzinski.
TN SCOREâ€śBeing chosen to take part in such a prestigious event is a real honor for our students and a good reflection on our departmentsâ€ť said Gabriel A. Goenaga, senior research associate in the Zawodzinski Group. â€śWe encourage students to go to conferences, giving them the opportunity to display their research among some of their best and brightest peers.
â€śIt is a great opportunity and good experience for their future careers.â€ť
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.
â€śWeâ€™re really pleased for them to get that level of recognition while representing our university,â€ť said Goenaga. â€śTo have that many high finishes from one research group is confirmation for both our students and our research group.â€ť
The Tennessee Solar Conversion and Storage using Outreach, Research and Educationâ€”or TN-SCOREâ€”program, of which Zawodzinski is the Thrust II leader, made the trip and poster presentations possible.

New ARPA-E Award to Develop Improved Energy Storage Systems | Knoxville, TN | July 30, 2014
From the TN-SCORE news page:
The DOE ARPA-E REBELS (Reliable Electricity Based on Electrochemical Systems) program recently awarded $2,750,000 to support development of nanocomposite electrodes. TN-SCORE researchers at UTK will work with Oak Ridge National Laboratory (ORNL) to develop and demonstrate novel electrode materials and designs to lower the cost and improve the performance of fuel cells. UTK/ORNL Governorâ€™s Chair Professor and TN-SCORE Co-PI Dr. Tom Zawodzinski says â€śthe core of the project is the development of revolutionary new ways to combine carbon, catalysts and a unique electrolyte to create a more effectively packaged composite electrocatalytic active layer. It also builds from demonstrations in our lab of the high tolerance of this type of fuel cell to impure hydrogen streams and incorporates some approaches to replacing Platinum with less costly metals.â€ť
The redesigned electrode is expected to dramatically increase the amount of surface area, lowering the amount of expensive platinum catalysts used in the cell. This will enable efficient distributed electricity generation from domestic fuel sources using less expensive catalysts. Key researchers include TN-SCORE faculty Dr. Alex Papandrew and Dr. Gerd Duscher, and UTK Energy Scholar David Wilson, who has been working on aspects of the technology that led to this project.

WattJoule Licenses Exclusive Rights to Breakthrough Energy Storage Technology | Lowell, Massachusetts | December 18, 2013
From PR Newswire:
WattJoule Corporation, a developer of next-generation flow battery energy storage systems, has entered into an exclusive, worldwide intellectual property licensing agreement with the University of Tennessee Research Foundation. This agreement allows the full commercialization of patent pending, breakthrough energy storage technology developed over the last three years and funded by the Department of Energy's Office of Electricity Delivery and Energy Reliability, under the program leadership of Dr. Imre Gyuk; the Office of Naval Research; and the National Science Foundation.
One of the major barriers preventing the widespread adoption of large-scale energy storage has been cost. WattJoule is engineering a new product platform based on the flow battery concept where electricity is stored in a liquid. WattJoule's liquid is mostly water and is inexpensive to make in large quantities. Flow battery systems today suffer from a number of limitations that have been hard to solve until several recent breakthroughs in the field.
"We set out to bring a different perspective to improving the performance of these devices and that has paid major dividends," said Dr. Tom Zawodzinski, UT Knoxville Professor & UT-ORNL Governor's Chair in Electrical Energy Storage and Conversion Systems. "We are systematically improving all aspects of performance at the cell and material level and building a thorough understanding of the foundations of the technology at the same time."

While there she was able to learn the fundamentals of a variety of new techniques for the characterization of thin films, nanostructures and nanoparticles and its application in the fields of renewable energies and lightweight construction. Besides, she had the opportunity to consult experienced experts in the field of physical and chemical analysis.

Zinc-air Battery Company Claims Novel Electrolyte Will Do The Trick | September 9th, 2013
From Clean Technica:
Ron Brost, CTO and CEO of ZAF Energy Systems, reports his research team has developed a zinc-air prototype that produces two times the energy of a lithium-ion battery at a third of the cost, with applications ranging from powering cell phones to airplanes.
Advantages of zinc over lithium-ion are many and obvious: zinc is a readily available and cheap mineral, with resources totaling 1.9 billion tons worldwide; it costs about a third what lithium costs; it weighs about half what lithium weighs in comparable applications; and while lithium-ion batteries have caught fire under certain trials, zinc is environmentally benign, going to zinc oxide (the main component of baby powder) after playing out in a battery. And zinc oxide is easily recyclable; Brost claims the ZAF battery itself will be recyclable.
Thomas Zawodzinski, Governor’s Chair in Electrical Energy Storage at the University of Tennessee Knoxville, has verified the general claims made by Brost and Wilkins. “They’ve got something that works. They definitely have a rechargeable battery,” he said in an interview, adding, “It’s always a question of efficiency.”
