Han-Ill Yoo

SNU, Korea

Prof. Han-Ill Yoo went to Seoul National University for BS and Korea Advanced Institute of Science and Technology for MS both in materials, and finally got Ph.D in Ceramics from the Department of Materials Science and Engineering, Massachusetts Institute of Technology, USA. in 1984. He has since affiliated with the faculty of the Department of Materials Science and Engineering, Seoul National University.
He has been teaching Thermodynamics, Kinetics, Defect Chemistry, and Solid State Ionics and authored a thermodynamics textbook, Thermodynamics of Materials Unraveled (in Korean) and a kinetics textbook, Lectures on Kinetic Processes in Materials (in English; to be published).
His research interest has been mainly with the defect chemistry and transport properties of mixed ionic electronic conductors, publishing 210 odd scientific papers and delivering ca. 70 invited or plenary scientific talks at international conferences. Among others, he discovered a material with 0 thermopower, implemented the experimental methods to determine all the ionic and electronic transport properties in terms of the Onsager transport coefficients, and experimentally confirmed the Onsager reciprocity between ionic and electronic flows. Recently, he has been inquiring into the nonisothermal ionic/electronic transport properties, or thermomigration, of mixed conductors.
He was awarded the Humboldt Research Award in 2004 and elected to Fellow by College of Engineering, The University of Tokyo in 2009. He is now serving as the President Elect and Vice President of the International Society of Solid State Ionics.
His lifelong passion was trekking into high mountains including Mt. Kilimanjaro (5895m high) in Tanzania; Kala Pattar (5,545 m), Annapurna Base Camp (4130 m), Gosainkund (4380 m), Kyangjin Ri (4550 m), Langtang Himal in Nepal, Mt. Rinjani (3726 m) in Indonesia, etc.
