Talk Title: Cellular NeuroMechanics -“ Concussions, Traumatic Brain Injury and the mysterious Havana Syndrome
Abstract: Current prediction, prevention and diagnosis strategies for mild traumatic brain injuries, including concussions, are still largely in their infancy due to a lack of detailed understanding and resolution of how physical forces give rise to tissue injury at a cellular level. In this talk I will present some recent work on our current understanding of the origin of concussions and traumatic brain injuries and how cells in the brain interpret and react to the physical forces of trauma. Specifically, I will show that the path to a better understanding of traumatic injuries involves addressing a variety of finite deformation, rate-dependent soft matter and cell mechanics problems along the way. Finally, I will provide an update on how our current understanding of the cellular neuromechanics cannot only help shed light on improving our prediction of TBI but also enable us to dissect the physical origin of emerging injuries such as the Havana Syndrome.
Biography: Christian Franck is a mechanical engineer specializing in cellular biomechanics and new experimental mechanics techniques at the micro and nanoscale. He received his B.S. in aerospace engineering from the University of Virginia in 2003, and his M.S. and Ph.D. from the California Institute of Technology in 2004 and 2008. Dr. Franck held a post-doctoral position at Harvard investigating brain and neural trauma. He was an assistant and associate professor in mechanics at Brown University from 2009 - 2018, and is now the Grainger Institute for Engineering Professor in Mechanical Engineering at the University of Wisconsin-Madison.
His lab at the University of Wisconsin-Madison has developed unique three-dimensional full-field imaging capabilities based on multiphoton microscopy and digital volume correlation. Current application areas of these three-dimensional microscopy techniques include understanding the 3D deformation behavior of neurons in the brain during traumatic brain injuries, and the role of non-linear material deformations in soft matter.
He is the acting director of the Center for Traumatic Brain Injury at the University of Wisconsin-Madison and the ONR-funded Physics-based Neutralization of Threats to Human Tissues and Organs (PANTHER) program, which consists of over 24 PIs nationwide. Key objectives of the Panther program are in better detection, prediction, and prevention of traumatic brain injuries by providing accelerated translation from basic science discovery to civilian and warfighter protection solutions.

Talk Title: Elucidating the thermodynamic origins of reaction heterogeneity in lithium-ion batteries
Abstract: During battery cycling, pronounced reaction non-uniformity frequently develops at multiple length scales within electrodes, which adversely impacts battery performance and life by inducing capacity under-utilization, stress concentration and over-(dis)charging. While heterogeneous reactions are typically attributed to mass transport limitations, thermodynamic factors also play an important role and need to be clarified for developing effective mitigation strategies. At the particle level, we reveal how stress could destabilize the lithium (de)lithiation front in single crystalline and polycrystalline intercalation compounds. Stress also provides a fundamental thermodynamic driving force for dendrite growth on lithium metal anodes, which is shown to be effectively suppressed by stress relief. At the cell level, we discover that the reaction distribution within the porous electrode is strongly influenced by how the equilibrium potential of the active material varies with the state of charge. Two types of reaction behavior are identified for common electrode materials, which have significant implications for their applications in thick electrodes. Based on this finding, an analytical model is formulated to provide highly efficient battery performance predictions and optimization in place of traditional battery cell simulations.
Biography: Ming Tang is an Associate Professor in the Department of Materials Science and NanoEngineering at Rice University. After receiving a Ph.D. degree in Materials Science and Engineering from MIT, He worked at Lawrence Livermore National Laboratory as a Lawrence Postdoctoral Fellow and then a staff scientist. In 2013 he joined Shell Oil as a materials and corrosion engineer, and became an assistant professor at Rice University in 2015. His group is currently interested in applying combined modeling and experimental methods to understand mesoscale phenomena in energy storage systems and use the acquired knowledge to guide microstructure design. He is a recipient of the DOE Early Career Award.

Talk Title: Cool Fuel: Engineering Liquid Hydrogen for the Future of Zero-Carbon Transportation
Abstract: The new HydrogenShot initiative launched by the US Department of Energy has the ambitious goal of reducing hydrogen fuel production costs to $1 for 1 kg in 1 decade. Behind the scenes of this goal is an incredible logistics challenge to store and distribute the massive amounts of hydrogen needed. Currently over 90% of small merchant hydrogen is distributed via cryogenic liquid tanker truck. However, modern hydrogen liquefiers have specific energy consumptions only 30% of what is theoretically achievable for ~30 tonne/day systems approaching $100M in cost. Clearly, hydrogen liquefaction cycles must fundamentally change to massively scale with clean energy resources. Once liquefied, the next challenge is minimizing parasitic heat transfer that results in boil-off losses typically between 7-40%. New paradigms for liquid hydrogen storage are needed to minimize these losses. Although many challenges remain to be solved, the purpose of this talk is to emphasize the new tools and opportunities making this cool fuel an exciting research area for several decades to come.
Biography: Jacob Leachman is an Associate Professor in the School of Mechanical and Materials Engineering at Washington State University (WSU). He initiated the Hydrogen Properties for Energy Research (HYPER) laboratory at WSU in 2010 to advance cryogenic and/or hydrogen systems. To this day the HYPER laboratory remains the only US academic laboratory focusing on cryogenic hydrogen. He earned a B.S. degree in Mechanical Engineering in 2005 and a M.S. degree in 2007 from the University of Idaho. His masters thesis has been adopted as the foundation for hydrogen fueling standards and custody exchange, in addition to winning the Western Association of Graduate Schools Distinguished Thesis Award for 2008. He completed his Ph.D. in the Cryogenic Engineering Laboratory at the University of Wisconsin-Madison in 2010 under the advice of John Pfotenhauer and Greg Nellis. He is the lead author of the reference text Thermodynamic Properties of Cryogenic Fluids: 2nd Edition and Cool Fuel: The Science and Engineering of Liquid Hydrogen which is in development. In 2018 he received the Roger W. Boom Award from the Cryogenic Society of America.
