A special issue in Plasma Chemistry and Plasma Processing is published regularly after every ISPC, highlighting a collection of plenary and invited lectures. It is indeed an important milestone in the activity of ISPC, presenting the most recent progress of plasma chemistry research. Please refer to the previous special issues on the journal home page (https://link.springer.com/journal/11090/volumes-and-issues).
On behalf of all BoD and IOC members, the guest editors of the special issue would like to thank the Plenary and Invited Speakers for their valuable contributions!
