Bridging the gap between modeling and experiments in low temperature plasmas

Abstract: Low-temperature plasma (LTP) science and technology have become integral to numerous applications with far-reaching implications for our society. From advancing microelectronics industry through plasma–surface interactions and microprocessor fabrication to enabling electric propulsion systems for satellite motion control, LTPs play a pivotal role in diverse fields.

The continuous evolution of LTPs has given rise to novel application areas, including multidisciplinary research domains such as plasma agriculture, plasma catalysis and plasma-based gas reforming. Despite these advancements, understanding and controlling non-equilibrium plasma processes remain challenging due to the need to identify key phenomena operating across spatial and temporal scales spanning several orders of magnitude.

This seminar will explore ongoing efforts dedicated to understanding the key role played by parameters of relevance (electric field, vibrational excitation, gas heating, etc.) in LTPs. The presentation will be particularly focused on plasma-based applications targeted at converting pollutant gases into value-added products, offering sustainable alternatives to fossil fuels, thereby contributing to the decarbonization of energy systems.

I will discuss past, current and future activities aimed at advancing our understanding of LTPs by closing the gap between modeling and experimental results. The talk will also underscore the challenges associated with establishing benchmark experiments for model validation and simplifying complex plasma kinetic schemes.
