On behalf of the International Plasma Chemistry Society (IPCS), we welcome everyone to the 22nd International Symposium on Plasma Chemistry, which will be held from the 5th to the 10th of July 2015 in Antwerp, Belgium. ISPC 22 will be held at the City Campus of the University of Antwerp. The symposium venue is within the city centre and close to the central railway station. Antwerp is only 42 km from Brussels (Zaventem) National Airport, and 165 km from Amsterdam Schiphol Airport; both airports have numerous connections to major airports all over the world. Antwerp is an international city (population ~500,000), which has nevertheless succeeded in remaining pleasantly cosy and in keeping everything within convenient reach. The numerous historical monuments and museums are a tribute to its glorious past. Some of the museums have a worldwide reputation, such as the Rubens House and the Plantin-Moretus printing museum, containing unique collections. The ISPC has gained popularity over the past few years and represents scientists from all major continents of the world. Its breadth of subject matter has now expanded and we will have sessions on both thermal and non-thermal plasmas, with emphasis ranging from fundamentals, diagnostics and modeling, plasma sources, microdischarges, plasma in liquids, to the many applications, such as plasma medicine, environmental applications and renewable energy, materials science, microelectronics, …
