From 16th to 17th of October 2025 the University of Bremen hosted the fifth annual meeting of the Priority Program 2289 “Hetero-Aggregates (SPP 2289)” coordinated by Lutz Mädler. SPP 2289 focuses on the design, description and understanding of processes towards hetero-aggregates, i.e. aggregates made up of (at least two) distinctly different types of nanoscale primary particles to create new functional materials. The goal is to comprehend and leverage particle-level synergies for applications in various fields such as e.g. photo catalysis, energy storage or catalysis.

This year’s meeting featured concise presentations followed by in-depth discussions, fostering a dynamic exchange surrounding research methods, results, and emerging approaches. Researchers from 16 interdisciplinary projects came together to present their current findings, discuss ideas, and outline future research directions.

Recent experimental and numerical insights into hetero-aggregate formation from the joined project “Formulation of hetero-aggregates in continuously-operated opposed jet fluidized beds”  between the Chair of Thermal Process Engineering of Otto von Guericke University of Magdeburg (PI: Andreas Bück) and the Particle Processing Group of IPT of FAU (PI: Jochen Schmidt) were presented by Kristin Kaschel and Muhammad Usman Farid.

With SPP 2289 now having been funded for four of the six years of the total project duration, the possibility of transferring the fundamental knowledge gained to applications in industry was discussed. It was inspiring to see how the projects and collaborations with SPP 2289 had evolved at this year’s annual meeting, and how different ideas and research methods had been combined into interdisciplinary concepts that will undoubtedly lead to exciting developments.
