Particles and particle-based materials (PBM) are everywhere and will play a crucial role to enhance sustainability of processes and products. The PBM Symposium 2022 thus particularly welcomes contributions dealing with PBM in fields such as energy (generation, storage, transformation), catalysis, recycling, purification and recovery, extension of materials lifetime or damage indication. Besides this, fundamental contributions to better understand the formation or the properties of complex particle systems are very welcome as well.
