A Foreword from the Organizing Committee

 As President of the International Plasma Chemistry Society (IPCS) and Co-Chairs of the International Organizing Committee, we are pleased to welcome you to the 25th International Symposium on Plasma Chemistry (ISPC25). The Symposium aims to provide an ideal venue for fruitful discussion among those working on plasma chemistry. The ISPC25 is organized by the International Plasma Chemistry Society (IPCS), an international not-for-profit professional society in the field of plasma chemistry, which was established in 1999 as the successor of the “International Union of Pure and Applied Chemistry (IUPAC) Subcommittee on Plasma Chemistry.”

 The ISPC has a long history, dating back to well before the establishment of the IPCS. The Symposium was first held at Kiel, Germany, in 1973, and, since then, has been held biennially at various locations around the world, except for the year 2021, when the ISPC25 was postponed to this year due to the COVID-19 pandemic. Following the time-honored tradition of the ISPC, we have also organized the IPCS Summer School in a nearby hotel over the weekend prior to the ISPC25.

 The City of Kyoto offers the charm of both traditional and modern Japan to its visitors. We hope the Symposium participants also enjoy the City of Kyoto and its surrounding areas, in addition to reaping the maximum academic benefits of the ISPC25.
