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.

Dr. Kostka is currently a professor of Biology at Georgia Institute of Technology (GT). Prior to GT, he was an Associate Professor at the Department of Oceanography, Florida State University. His research involves microorganism studies in geochemical cycles of pristine and contaminated ecosystems, from the oceans to the terrestrial subsurface.

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.

Bernard Kippelen was born and raised in Alsace, France. He studied at the University Louis Pasteur in Strasbourg where he received a Maitrise in Solid-State Physics in 1985, and a Ph.D. in Nonlinear Optics in 1990. From 1990 to 1997 he was Charge de Recherches at the CNRS, France. In 1994, he joined the faculty of the Optical Sciences Center at the University of Arizona. There, he developed a research and teaching program on polymer optics and plastic electronics. In August 2003, Dr. Kippelen joined the School of Electrical and Computer Engineering at the Georgia Institute of Technology where his research ranges from the investigation of fundamental physical processes (nonlinear optical activity, charge transport, light harvesting and emission), to the design, fabrication and testing of light-weight flexible optoelectronic devices and circuits based on nanostructured organic materials. He currently serves as director of the Center for Organic Photonics and Electronics, and as co-president of the Lafayette Institute, a major optoelectronics commercialization initiative that is based at Georgia Tech-Lorraine in Metz, France. He currently holds 25 patents and has co-authored over 270 refereed publications and 14 book chapters. His publications have received over 20,000 citations and his h-index is 73 (Google Scholar). He served as chair and co-chair of numerous international conferences on organic optoelectronic materials and devices and as deputy editor of Energy Express. He was the founding editor of Energy Express.

In the Kaiser group, we work to improve the understanding of the emissions and atmospheric processes that influence air quality and climate. Our research focuses largely on volatile organic compounds (VOCs), which are reactive organic species that are precursors to ozone and aerosol. Our work is grounded in insights from field, and aimed at understanding atmospheric composition at broad spatial and temporal scales.

Prior to joining the Georgia Tech faculty in 2001 as a Professor, Yogendra Joshi held academic positions at the University of Maryland, College Park, and the Naval Postgraduate School, Monterey, California. He also worked in the semiconductor assembly industry on process thermal model development. He was named to the McKenney/Shiver Chair in 2004.

Chris Jones was born in suburban Detroit, Michigan in July of 1973. After his primary and secondary schooling and 14 years living Troy, Michigan, he enrolled as a chemical engineering student at the University of Michigan. In route to earning a BSE in chemical engineering, Chris carried out research on transition metal carbide and nitride catalytic materials under the direction of Levi Thompson. After graduating in 1995, Chris moved to Pasadena, California, to study inorganic materials chemistry and catalysis under Mark E. Davis at Caltech. There he earned M.S. and Ph.D. degrees in chemical engineering in 1997 and 1999, respectively. Subsequently, he studied organometallic chemistry and olefin polymerization under the direction of both Davis and John E Bercaw at Caltech. He started as an assistant professor at Georgia Tech in the summer of 2000 and was promoted to associate professor in July 2005. In May, 2005, he was appointed the J. Carl and Sheila Pirkle Faculty Fellow, followed by a promotion to professor in July 2008. He was named New-Vision Professor of Chemical and Biomolecular Engineering in July 2011.

In this role, he directed 50% of his time on campus-wide research administration with a primary focus on interdisciplinary research efforts and policy related to research institutes, centers and research core facilities. In 2018, he served as the interim executive vice-president for research, before returning full time to his research and teaching roles in chemical and biomolecular engineering in 2019.

Jones directs a research program focused primarily on catalysis and CO₂ separation, sequestration and utilization. A major focus of his laboratory is the development of materials and processes for the removal of CO₂ from air, or “direct air capture” (DAC).
