Baratunde A. Cola is a professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering at the Georgia Institute of Technology. He received his degrees from Vanderbilt University and Purdue University, all in mechanical engineering, and was a starting fullback on the Vanderbilt football team as an undergrad. Cola has received a number of prestigious early career research awards including the Presidential Early Career Award for Scientist and Engineers (PECASE) in 2012 from President Obama for his work in nanotechnology, energy, and outreach to high school art and science teachers and students; the AAAS Early Career Award for Public Engagement with Science in 2013; and the 2015 Bergles-Rohsenow Young Investigator Award in Heat Transfer from the American Society of Mechanical Engineers. In addition to research and teaching, Cola is the founder and CEO of Carbice Corporation, which sells a leading thermal management solution for the global electronics industry.

Materials for membranes, sorbents, and barrier packaging applications rely upon the same fundamental principles. Thermodynamically controlled partitioning of a penetrant, such as carbon dioxide into a membrane, sorbent or barrier packaging layer is the first step in the transport process. If the material is a polymer, cooperative motions of the matrix enable diffusive motion by the penetrant. In highly rigid carbon molecular sieves and zeolites, motion of the matrix is negligible, and penetrant transport is governed by the relative size of pre-existing pores and the penetrant molecule.

Koros’s group is a leader in developing advanced materials for membranes, sorbents, and barrier applications by optimization materials to either promote or retard transport of specific components. For instance, for a chosen penetrant such as carbon dioxide, the Koros group can create a barrier, a selective membrane, or a sorbent by materials engineering. Work is also underway in the Koros group to form “mixed matrix composite” materials comprised of blends of metal organic framework or other specialty components within the matrix of a conventional polymer. This approach allows further optimization of transport properties without sacrificing the ease of processing associated with conventional polymers.

Effects due to non equilibrium thermodynamic and non-Fickian transport phenomena are additional topics his group studies. Long lived conditioning effects due to exposure of membranes and barriers to elevated concentrations of certain penetrants are typical of such non equilibrium phenomena. Protracted aging of glassy polymers, carbons, and inorganic membranes after formation or conditioning treatments also are of interest to his research group. In many cases, these effects seem to defy logic—until one realizes that an expanded set of rules governs these out-of-equilibrium materials.

Paul Kohl received a B.S. degree from Bethany College in 1974 and Ph.D. from The University of Texas, both in Chemistry. After graduation, Kohl was employed at AT&T Bell Laboratories in Murray Hill, NJ from 1978 to 1989. During that time, he was involved in the design and processing of electronic packages for Bell system components. He created new chemical processes for silicon, compound semiconductor, and MEMS devices. In 1989, he joined the faculty of the Georgia Institute of Technology in the School of Chemical and Biomolecular Engineering, where he is currently a Regents' Professor and holder of the Thomas L. Gossage/Hercules Inc. Chair. He is the President of The Electrochemical Society and past Editor of Journal of The Electrochemical Society and past founding editor of Electrochemical and Solid-State Letters. Kohl's research interests include the design of new materials, processes, and packages for advanced interconnect for integrated circuits and MEMS devices. He is the past Director of the Semiconductor Research Corporation/DARPA Interconnect Focus Center. The goal of this center was to create new technological solutions for future electronic devices. Current projects include creation of new photosensitive dielectric materials for electronic packaging and the design and fabrication of MEMS packages. He also has programs in new approaches to fuel cells and lithium batteries. The new direct methanol alkaline fuel cells and hybrid alkaline/acid fuel cells have the potential reduced water management and platinum free usage. The integration of high energy density lithium batteries for self-powered integrated circuits and sensors is of interest. Many of these electrochemical devices use ionic liquids as the electrolytes, including the all-sodium battery. Ionic liquids are also being used as the absorber in a new absorption refrigeration cycle. The first ever ionic liquid/fluorocarbon absorption refrigeration cycle has been demonstrated and modeled.

Our interests lie in the adhesion and signaling molecules of the immune system as well as those involved in platelet adhesion and aggregation. We are primarily focused on early cell surface interaction kinetics and their primary signaling responses, as these are critical in determining how a cell will ultimately respond upon contact with another cell. The majority of our work ranges from single molecule interaction studies using atomic force microscopy, molecular dynamics simulations, or biomembrane force probe assays to single cell studies using micropipette adhesions assays, fluorescence imaging techniques, or real-time confocal microscopy. These assays focus on the mechanics and kinetics of receptor-ligand binding and their downstream signaling effects within cells. T cell receptors, selectins, integrins, and their respective ligands are some of the cell surface molecules currently under investigation in our lab. Understanding the initial interaction between molecules such as these and their subsequent early signaling processes is crucial to elucidating the response mechanisms of these physiological systems. Ultimately, our research strives to help better understand the mechanisms within these systems for possible medical applications in autoimmunity, allergy, transplant rejection, and thrombotic disorders.
