The focus here was on transferring technological developments to industrial applications. Atmospheric plasmas have already demonstrated their potential many times over as innovative solution approaches for both local and large-area surface treatments. In addition to a wide range of technical applications for surface modification of plastics and metals, textile materials and composites, this now includes applications in agriculture in the pre-harvest process. A presentation on new surface and coating characterization methods for the quality control of a plasma treatment highlighted the optical inspection of ultra-thin _SiOx coatings during production. Extensive opportunities for discussion during the presentations and coffee breaks were gladly used and continued at the established regulars' table.

The competition #ZukunftADP(https://www.ak-adp.de/zukunftsarena/), which was offered by ak-adp 2021 for the first time, was continued in 2023 in search of THE future topics of plasma research and industrial use. The contributions submitted by students and renowned scientists were presented and awarded on the 2nd workshop day - congratulations to the winners. The winner - Mr. Martin Leander Marxen from the CAU in Kiel - can look forward to a financial support of 1000€ for the continuation of his research work relevant for the energy turnaround on "Reduction of _N2 and_CO2 to higher-value molecules by means of plasma-supported electrocatalysis". Second place in the Future Competition went to an entry from INNOVENT. Oliver Beier, Jun Xu and Jürgen Schmidt presented the use of atmospheric pressure plasmas for the activation and functionalization of surfaces prior to chemical metal deposition with their competition submission "Resource and environmentally friendly methods for the activation of dielectric surfaces for subsequent chemical metallization". Third place was awarded to Madleen Westphal and Tobias Landgraff from TH Lübeck with an entry from the field of additive manufacturing "Atmospheric plasma treated polymer base plates in 3D printing of plastic components". Furthermore, all participants in the competition will be given the opportunity to publish their competition ideas and associated project work as part of an exclusive collaboration with the trade magazine WOMAG. This offer also applies to the 2021 competition participants who, after 2 years, have taken the opportunity to present results of the implementation of their ideas.

Last but not least, the exciting workshop was rounded off by a lecture on data security with a focus on current industrial espionage and computer security - a topic that concerns everyone and can suddenly affect them in everyday life. The workshop also included participation in a special tour of parts of the restoration workshops of the Museum of Applied Art and the Museum of Ethnology. Here, the potential of plasmas as a tool for restoring museum objects was discussed using actual collection pieces. Further collaboration with the restorers is planned.
