7:30 - Speaker : Igor Kosacki

ADVANCED NANOSCALED ION CONDUCTORS FOR ENERGY APPLICATION
Igor Kosacki - Shell Exploration & Production, Westhollow Technology Center, Houston, TX 77082

Nanoscience and nanotechnology are concerned with materials in the size range typically from 100 nm down to the atomic, because it is in this range that materials can have different or enhanced properties compared with the same materials at a larger size. The two main reasons for this change in behavior are an increased relative surface area, and the dominance of quantum effects. An increase in surface area will result in a corresponding increase in chemical reactivity, making some nanomaterials useful as catalysts, sensors and as electrodes to improve the efficiency of fuel cells and batteries.

In this lecture, the ability to enhance the physical properties of oxygen conductors will be discussed. The parameters determining the ionic transport in solids are reviewed, and the case for enhanced ionic conductivity is considered. Some recent highlights in nanoscience and technology in the synthesis, properties and applications of nanoscale materials will be described. Presented results were obtained during my work at University of Missouri-Rolla and Oak Ridge National Laboratory.

To demonstrate the advantage of nanomaterials, they were evaluated as solid electrolytes in solid oxide fuel cells. The results showed an enhancement in both power and current densities for nanomaterial-based cells as compared to the common used ceramic electrolyte cell. The high performance of the nanoscaled electrolyte fuel cell illustrates the tremendous potential of nanomaterials and offers new opportunities for the application of oxygen conductors in electrochemical devices.

Bio: Igor Kosacki

Igor Kosacki received his M.Sc. (1978) in experimental physics from University Maria Curie-Sklodowska, Lublin, Poland and his Ph.D. (1983) and Dr.Hab. (1991) degrees in solid state physics from the Institute of Physics, Polish Academy of Sciences, Warsaw, Poland. He then worked as Assistant Professor in the Department of Physics, Radom Technical University. In 1992, Igor Kosacki joined the Crystal Physics and Electroceramics Laboratory at Massachusetts Institute of Technology, where he worked with Prof. Harry Tuller. In 1995-2001 he was employed by University of Missouri-Rolla as Research Associate Professor joining Prof. Harlan Anderson research group. Next he was working as Senior Research Staff Member in Oak Ridge National Laboratory (2001-2006) and recently (since 2006), he joined Shell as Senior Scientist. Igor Kosacki served as Post-doctoral Fellow at University Pierre and Marie Curie, Paris (1990), Delft University of Technology, Holland (1991-1992) and Massachusetts Institute of Technology (1992-1993).

Igor Kosacki was the recipient of a CNRS Award for Visiting Professor, University of Pierre and Marie Curie in Paris (2001) and the Award of the Scientific Secretary of Polish Academy of Sciences for achievements in the research of superionic conductors (1989). He also received the number of Awards of the Rector of Radom Technical University for the achievements in the research and teaching excellence (1983, 1984, 1986, 1987, 1988, 1989). In 1985 he was recipient of the Award for The Best Young Scientist.

Igor Kosacki’s scientific interests are focused on the research and development of functional materials for energy conversion including solid oxide fuel cells, gas sensors and electrical batteries. This includes processing of materials and their characterization using optical spectroscopy (Raman scattering, optical absorption) and electrical conductivity (DC and AC) techniques. His current research emphasizes the defect structure and matter transport mechanism in nanoscaled oxide thin films. Studies involve the quantum and phonon confinement effects and they correlation with electrical transport and optimization of solid electrolytes for electrochemical devices. His special interests are connected with the technology and characterization of nanocrystalline ceramic thin films and ion conductive superlattice structures and the study of their electrical and optical properties related to grain boundaries and interfaces.

Igor Kosacki has authored more than 100 articles in refereed journals including 7 invited review papers and chapters in the books. He has given numerous of invited lectures at international conferences and has more than 1200 citations in the scientific literature.
