Combined USAXS, SAXS, WAXS techniques for studying the oxidation of soot nanoparticles in a flame

This proposal aims to investigate the oxidation of soot particles produced during combustion processes, with a focus on understanding the impact of different fuels, including sustainable aviation fuel (SAF). Soot particles, which have known links to health issues and climate change, will be studied using a double-stage burner and advanced optical techniques. The addition of Small-Angle X-ray Scattering (SAXS) at ESRF will allow for detailed analysis at smaller scales. The study aims to isolate and better understand the oxidation process, contributing to improved combustion and emission reduction in the aeronautic industry. The requested beamtime at the ID02 beamline is justified for its unique capabilities in examining particle sizes and morphology. The expected results will inform numerical simulations and aid in developing models for soot oxidation, potentially impacting emissions reduction strategies.
