The partners in the thin film product category held the first PK1 workshop of the implementation phase on 27 February. We were pleased to welcome renowned scientists from all over Germany, including world-leading experts in the fields of ceramic materials, membranes and catalysis, as guests to the workshop. We would like to express our special thanks to Professor Dr. Jürgen Caro, Institute for Physical Chemistry and Electrochemistry at Leibniz University Hannover, Dr. Theodor Schneller, Institute for Electrical Engineering Materials II at RWTH Aachen University, Dr. Ralf Kriegel, High Temperature Separation and Catalysis at the Fraunhofer Institute for Ceramic Technologies and Systems, Dr. Mariya Ivanova, Gas Separation Membranes Working Group at Forschungszentrum Jülich, and Dr.-Ing. Christian Vedder, Thin Film Process Technology at Thin Film Processing at the Fraunhofer Institute for Laser Technology ILT, for their groundbreaking keynote speeches and important input for the implementation of the Campfire projects. In the afternoon, there was an exciting brainstorming session and exchange of ideas for the further development of thin-film-based technologies for the production and use of ammonia. We look forward to future projects and new partnerships to implement our vision.
