Chemical engineering continues to grow in prominence, and we are proud that <i>CIT</i> remains vital, reflecting Wiley's strategic focus on this field.</p><p>We are delighted to introduce our new team: Martin Graf-Utzmann is joining as Deputy Editor, and myself as Editor-in-Chief. We are committed to building a strong foundation laid by our predecessors. In particular, we would like to thank the former Editor-in-Chief, Sabine Wiederhold, for her dedication, and the countless contributions that have shaped <i>CIT</i> through last couple of years.</p><p>Our curatorium board has also undergone a few changes, we thank Norbert Asprion and Michael Mangold for their valuable service and warmly welcome Jörg Sauer, Christof Hamel, and Pascal Schäfer to the board for bringing together both continuity and new perspectives. These changes ensure that <i>CIT</i> continues to serve as a dynamic platform for cutting-edge research and innovation in chemical engineering.</p><p>At this point, we want to address our German-speaking community directly: <i>Vielen Dank an unsere starke und engagierte chemisch-technische Gemeinschaft in Deutschland und in ganz Europa</i>. Your commitment to high-quality research, and the strong connection between academia and industry make this community especially valuable in the field of chemical engineering. Your contributions have shaped <i>CIT</i> for decades, and we remain proud to serve as a central forum for your work.</p><p><i>CIT's</i> strength is also deeply rooted in the support and leadership of its supporting societies, <i>GDCh, DECHEMA, und VDI-GVC</i>. Their longstanding commitment to advancing chemical engineering and fostering collaboration across disciplines and sectors provides the foundation on which this journal thrives. We look forward to continuing this close partnership in the years ahead.</p><p>We are grateful to all our authors, reviewers, and readers. Your engagement makes our journal a thriving and collaborative community. As we look ahead, we warmly invite more of you to participate, whether by submitting your latest findings or by joining our reviewer community. Your expertise is invaluable to maintaining <i>CIT's</i> quality and impact. We also look forward to meeting old and new authors at meetings and conferences; you are always welcome to talk to us.</p><p>Together, with our new team, our dedicated community, and our strong partner societies, we look forward to a year filled with discovery, collaboration, and growth.</p><p><i>Happy New Year!
