We cordially invite you to attend ASAM-4, which is held at National Taiwan University of Science and Technology, Taipei, Taiwan, on October 22-25, 2013. This symposium is intended as a forum for interdisciplinary discussion between scientists and engineers from Asian universities, research institutions and companies, who are investigating or concerned themselves in advanced materials. Such materials can serve for improving and developing chemical engineering, nanotechnology, microelectronics, optics, environmental science and biomedical technologies, and they make human life healthy and comfortable in quality. ​The 1st Asian Symposium on Advanced Materials (ASAM) was organized by Institute of Chemistry of Far East Department of Russian Academy of Sciences and Far East National University, Vladivostok, Russia, in 2007. The 2nd ASAM was organized by Fudan University in Shanghai, China, in 2009, and the 3rd ASAM was organized by Kyushu University in Fukuoka, Japan, in 2011. Many distinguished scientists from Asian countries attended these symposiums. Now this sustainable scientific forum is going to be organized here in Taiwan in this year.
