Dr Liu received his Ph.D. in chemical engineering with the theoretical and practical combination of colloid and interface science under the supervision of Prof. Jyh-Ping Hsu at National Taiwan University in 1998. During the college life, he was nominated for the honor member of Phi-Tau-Phi scholastic honor society in 1993, won an award for excellent student of college in 1995, and passed the examination of Taiwan environmental engineering technician in 1995. His study on the colloid science has been published in the international SCI journals, more than twenty articles. After graduation, he was devoted to the study of the preparation of nanoparticles, nanofluids, and renewable energy in Industrial Technology Research Institute (ITRI) in 1998-2003. Dr Liu incorporated the technologies in colloid science and nanoparticles into the optical films in LCD such as polarizers, antireflection films, antiglare films, and diffusers during working for Compal Electronics, Inc. in 2004 and Daxon Technology, Inc. in 2005-2007. He joined National Yulin University of Science and Technology (in Taiwan) in 2007. He has over one hundred articles published in leading journals about surface science, nanomaterials and solar cells. His research interests include in low/high refractive index materials, optical properties of nanostructure surface, functional nanoparticles, transparent conductive films, and solar cells.
