Ru-Shi Liu received his bachelor's degree in chemistry from Shoochow University, Taiwan, in 1981, and his master's in nuclear science from the National Tsing Hua University, two years later. He gained one Ph.D. in chemistry from National Tsing Hua University in 1990, and one from the University of Cambridge in 1992. From 1983 to 1995 he worked as a researcher at the Industrial Technology Research Institute, before joining the Department of Chemistry at the National Taiwan University in 1995 where he became a professor in 1999. He is a recipient of the Excellent Young Person Prize, Excellent Inventor Award (Argentine Medal) and Excellent Young Chemist Award. Professor Liu has over 350 publications in scientific international journals as well as more than 80 patents to his name.

Hansan Liu is a researcher at the Oak Ridge National Laboratory, US Department of Energy. He obtained his Ph.D. in electrochemistry from Xiamen University where he studied cathode materials for lithium ion batteries. After graduation, he worked at the Hong Kong Polytechnic University and the National Research Council Canada on electrophotocatalysis and fuel cell electrocatalysis, respectively. He is currently working on next generation high-energy density batteries at ORNL. Dr. Liu has 14 years of research experience in the field of electrochemical energy storage and conversion. His research interests mainly include battery and supercapacitor materials, fuel cell electrocatalysts, and synthesis and applications of high surface area materials. He has authored and co-authored over 70 publications, including 3 books, 4 book chapters and 3 patent applications relating to batteries and fuel cells. Dr. Liu is an active member of the Electrochemical Society and the International Society of Electrochemistry.

Xueliang (Andy) Sun holds a Canada Research Chair in the development of nanomaterials for clean energy, and is Associate Professor at the University of Western Ontario, Canada. He received his Ph.D. in materials chemistry in 1999 from the University of Manchester, UK, after which he worked as a postdoctoral fellow at the University of British Columbia, and as a research associate at l'Institut national de la recherche scientifique, Canada. He is the recipient of a number of awards, including the Early Researcher award, Canada Research Chair award and University Faculty Scholar award, and has authored or co-authored over 100 papers, 3 book chapters and 8 patents. Over the past decade, Dr. Sun has established a remarkable track record in nanoscience and nanotechnology for clean energy, mainly in the synthesis and structure control of one-dimensional nanomaterials, as well as their applications for fuel cells and Li ion batteries.
