Franz studied Chemistry at the TU Chemnitz and at the TU Graz and then did his PhD in the Atmospheric Physic group at ETH Zürich. His research field was the investigation atmospheric aging process on soot particles and how this contributes to the formation of clouds. During that time Franz used a broad range of aerosol-based instrumentation to observe changes in the morphology and chemistry of isolated soot particles. Based on this work, he was granted with 195 kCHF by the SNSF (Swiss National Science Foundation) and Innosuisse over 18-months to develop a new method for the online-characterisation of the structure and surface of Carbon Black and similar materials. He is now commercialising this new analytical approach via his own company, FemtoG.

Petros Mubari is pursuing his Ph.D. in Process Engineering at IMT Mines Albi in France where he is in his final year. He completed his undergraduate studies in Chemical Engineering with honours, which sparked his interest in advanced process optimisation and sustainable technologies. He also holds master’s degrees in chemical engineering and materials engineering. Petros's passion for finding innovative solutions to real-world engineering problems led him to pursue a Ph.D. in the same field. He has demonstrated experience in waste management, tyre recycling, chemical/process engineering, mass and energy balances, materials science, carbon materials, solid mechanics, material characterisation, functional materials, computational modelling techniques, and product design. Throughout his Ph.D. journey, Petros has specialized in the recovery of carbon black from waste tyre pyrolysis. Along with understanding the properties of recovered carbon black, his research work also includes the application of carbon black in various domains, notably rubber reinforcement and as anodes in Li-ion batteries. Petros firmly believes that combining process engineering with circular economy principles is fundamental in creating a more sustainable and resource-efficient future, and he is determined to contribute to this vision.
