Lectures on Kinetic Processes in Materials
Description
This updated, second edition features a new section how to document and measure all the mass and charge transport properties of a material and a comprehensive solution manual for end-of-chapter exercise problems, that is designed to help readers themselves grasp and apply the fundamental knowledge of kinetics. It remains an essential primer for beginning graduate or senior undergraduate students in materials discipline, presenting fundamental and quantitative ideas on kinetic processes in materials. Kinetics is concerned with the rate of change of the state of existence of a material system under thermodynamic driving forces. Typically, kinetic processes in materials involve chemical reactions and diffusion either in parallel or in tandem. Thus, mathematics of diffusion in continuum is first dealt with in some depth, followed by the atomic theory of diffusion and a brief review of chemical reaction kinetics. As applications, then follow chemical diffusion in multi-component materials ( e.g., metallic alloys and mixed ionic electronic conductors), the kinetics of phase transformations, and the kinetics of gas-solid reactions. Through this course of learning and practice, a student will become able to predict quantitatively how fast a kinetic process takes place, to understand the inner workings of the process, and to design an optimal process for state changes in materials used in processing applications.

Person
Prof. Han-Ill Yoo received his Ph.D in Ceramics from the Department of Materials Science and Engineering, Massachusetts Institute of Technology (MIT), U. S.A. in 1984. He had since been affiliated with the faculty of the Department of Materials Science and Engineering, Seoul National University until his retirement in 2017 and then with the Daegu Gyeongbuk Institute of Science and Technology (DGIST) as an Invited Chair Professor for the next four years. He has taught Thermodynamics and Kinetics while pursuing lifelong research in defect chemistry and the mass and charge transport properties of ceramics. In the course of his work, he discovered an unusual non-superconducting ceramic with vanishing thermopower, established the experimental methods to determine, once and for all, all the mass and charge transport properties of a material in terms of the coupling coefficient matrix of the Onsagerian causality, and experimentally demonstrated the Onsager Reciprocity between ionic and electronic flows in mixed ionic electronic conductors. He is still delving into the thermomigration behavior of ceramics. He was awarded the Alexander von Humboldt Research Award in 2004 and elected a Fellow of the College of Engineering, the University of Tokyo in 2009. From 2017 to 2019, he served as President of the International Society for Solid State Ionics (ISSI) . Outside the laboratory, he was an avid high-altitude trekker, having climbed breathless peaks such as Mt. Kinabalu (4095 m), Annapurna Base Camp (4130 m), Mt. Kilimanjaro (5895 m), Lake Gosainkunda (4380 m), Mt. Kala Patthar (5643 m), and Mt. Rinjani (3726 m), among others.
