Introduction of Study Programs International Student Programs in Graduate School of / School of Engineering Science, Osaka University, Japan” Research Talk on Electrochemical Nanotechnology: Molecular Scale Understanding of Electrified Interfaces Introduction of Study Programs International Student Programs in Graduate School of / School of Engineering Science, Osaka University, Japan” Research Talk on Electrochemical Nanotechnology: Molecular Scale Understanding of Electrified Interfaces Graduate School of Engineering Science, Osaka University, welcome you to study and do research with us.

2. “International Student Programs in Graduate School of / School of Engineering Science, Osaka University, Japan” The Graduate School of Engineering Science, Osaka University, seeks to achieve a more prominent international reputation through their increased involvement in the exchange of students and researchers as well as joint research projects. These highly qualified and globally recognized graduate students will not only participate in cutting edge research, but also gain a sophisticated understanding of advanced engineering science topics. Please join us in exploring science and technology in the 21st century, through the guiding principles of the Graduate School of Engineering Science. ELECTROCHEMICAL NANOTECHNOLOGY: MOLECULAR SCALE UNDERSTANDING OF ELECTRIFIED INTERFACES Yasuyuki Yokota Graduate School of Engineering Science, Osaka University, Toyonaka, 560-8531, Japan; E-mail: yyokota@chem.es.osaka-u.ac.jp Since Volta invented the voltaic pile late in the eighteenth century, electrochemistry has been one of the most important fields of study not only for academia but for industry. For instance, some parts of thermodynamics and kinetics chapters in the textbook of physical chemistry were developed by electrochemistry, and recent energy-related subjects, such as fuel cell, secondary battery, solar cell, and electric double-layer capacitor, are included in electrochemical applications. There is a general consensus concerning the fundamental aspects of electrolyte / electrode interfaces. However, conventional electrochemical theory and measurement do not provide molecular scale pictures of the electrolyte / electrode interfaces, which hampers the development of the sophisticated electrochemical devices. In this seminar, I will present our recent achievements of molecular scale understanding of electrified interfaces, ionic liquid / solid interfaces and aqueous solution / solid interfaces, by the virtue of electrochemical nanotechnology.
