Prof. Jong-Sung Yu is one of the most renowned scientists in the field of electrochemical science. He is currently a professor in the Department of Advanced Materials Chemistry at Korea University in Seoul, South Korea. He received a bachelor of science in chemistry from Sogang University in 1983 in Korea and a PhD in chemistry at the University of Houston, Houston, Texas, USA, in 1990. He has several years of rich post-doctoral experience at Ohio State University, the University of Houston, Pennsylvania State University, and Northwestern University. He is currently on the editorial board of the Journal of Experimental Nanoscience (Taylor and Francis), Frontiers in Fuel Cells, and Carbon Letter (Korean Carbon Society). He was awarded an Excellent Research Award from the Inorganic Chemistry Division in 2011 and from the Material Chemistry Division in 2004 of the Korean Chemistry Society. He was also given a Korea Strategic Research Grant (2010-2015) in energy application. He has authored about 190 peer-reviewed articles and 60 patents. His research interests lie in nanostructured materials for storage, delivery, and conversion with particular attention toward electrochemical applications, such as fuel cell, battery, capacitor, solar cell, and sensors.

Energy is one of the prime needs of the modern world, and energy demands have been rapidly increasing in the recent years owing to rapid advancements in industrialization and population explosion. Conventional fossil fuels are being depleted at rapid rates, and the use of conventional sources such as coal or nuclear sources cause several hazards to
