Fabian P. Hagen: Carbon nanoparticles: From particle structure to macroscopic properties Abstract:Carbon nanoparticles (CNP) represent the most produced nanomaterial worldwide. CNPs are employed as functional- or electro-material, however, are also encountered in aerosols from combustion, as pollutants from fires, energy conversion processes, and internal combustion engines. The total global emissions of not-intended CNPs are in the same order of magnitude as for intended manufacturing. In this regard, they pose health hazards and contribute to global warming. Since both, their positive and negative aspects, originate from their structural nature, the presentation will focus on the structure of CNPs. It will provide insights into how macroscopic particle properties such as reactivity, optical properties and electrical conductivity can be controlled by modifying the CNP structure. This knowledge along with an understanding of the evolution of the CNP structure during particle formation in hydrocarbon flames offers opportunities for targeted synthesis of particles with tailored topologies and properties for practical applications. In addition, the presentation will introduce diagnostic tools for in situ and ex situ structural characterization, enabling the CNP structure to be tracked throughout their formation history.Biography:Dr. Fabian P. Hagen is a junior research group leader at the Engler-Bunte Institute, Division of Combustion Technology, at the Karlsruhe Institute of Technology (KIT), which is headed by Prof. D. Trimis. He earned a M.Sc. in Chemical Engineering with distinction from Technical University of Munich and completed his doctorate at KIT in 2023, where he was honored for his work on the structure of carbon nanoparticles. Dr. Hagen’s research group focuses on fundamental experiments involving particle-laden, chemically reacting flows. One of the goals of his group is to track and characterize the particle structure during nanoparticle synthesis and/or soot formation using intrusive and non-intrusive diagnostic tools. His group is also researching reactive micron-sized metal particles and their oxides with the potential to be used in a cycle as carbon-free chemical energy carrier.
