"NANOMATERIALS FOR BETTER BATTERIES, GAS SENSORS AND FUEL CELLS"

(VIDEO CONFERENCED FROM HOUSTON)
Abstract:
Nanoscience and nanotechnology are concerned with materials in the size range typically from 100 nm down to the atomic, because 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. These devices can play an important role in the development of novel energy conversion processes.
In this lecture, the ability to enhance the physical properties of oxygen and lithium conductors will be discussed. The effects related to scaling factors as grain size, thin film thickness and porosity of ion conductors will be discussed and illustrated by recent results obtained for nanoceramics, nanoscalled superlattices and mesoporous materials.
To demonstrate the advantage of nanomaterials, they were evaluated in solid oxide fuel cells, hydrogen gas sensors and lithium batteries. The results showed an enhancement in power and current densities, sensivity, response time for nanomaterial-based devices as compared to the common used materials. The high performance of such devices illustrates the tremendous potential of nanomaterials and offers new opportunities for their application in energy conversion.
Bio:
Speaker: Dr. Igor Kosacki Ph.D.
Igor Kosacki received his M.Sc. in experimental physics from Maria Curie-Sklodowska University, Lublin, Ph.D. and Dr.Hab. degrees in solid state physics from the Institute of Physics, Polish Academy of Sciences, Warsaw, Poland. In 1992, Igor Kosacki joined the Crystal Physics and Electroceramics Laboratory at Massachusetts Institute of Technology. In 1995-2001 he was employed by University of Missouri-Rolla as Associate Professor in Ceramic Engineering Department. 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'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 received Professor Title, the highest polish scientific title awarded by the President of Poland. He also received the number of international awards for the achievements in the research and teaching excellence. Igor Kosacki has authored more than 100 articles in refereed journals including 7 invited review papers and chapters in the books. He has more than 2000 citations in the scientific literature.
