The International Conference on Science and Technology of Synthetic Metals 2018 (ICSM 2018) will be held on July 1~6, 2018 at the Busan Exhibition & Convention Center (BEXCO) in Busan, Korea. The ICSM has been held at Siofok (1976), New York (1977), Dubrovnik (1978), Helsingor (1980), Boulder (1981), Les Arcs (1982), Abano Terme (1984), Kyoto (1986), Santa Fe (1988), Tubingen (1990), Göteborg (1992), Seoul (1994), Snowbird (1996), Montpellier (1998), Bad Gastein (2000), Shanghai (2002), Wollongong (2004), Dublin (2006), and Porto de Galinhas (2008), Kyoto (2010), Atlanta (2012), Turku (2014) and Guangzhou (2016). We, the Organizing Committee of ICSM 2018, are delighted that the 24th ICSM will be held back in Korea after the ICSM 1994 (Seoul). We will provide an excellent forum for interaction and developing friendship with participants from various countries who are involved in research, development, engineering, manufacturing and application of Synthetic Metals, from synthesis to characterization, computational modeling, device fabrication, and real-world applications. We wish you all to participate in the ICSM 2018 in Busan, Korea.
