معرفی
Shawon Barua is a Doctoral Researcher at the Department of Physics within the Faculty of Engineering and Natural Sciences at Tampere University. Their research focuses on understanding the molecular mechanisms of atmospheric aerosol formation, particularly through oxidation pathways of hydrocarbons and volatile organic compounds (VOCs). Key areas include the kinetics of reaction pathways leading to aerosol growth and clustering, employing mass spectroscopic methods and computational chemistry.
Research interests emphasize the environmental impact of aerosols on climate change, with a focus on urban emissions, traffic-related pollutants, and secondary aerosol production. Shawon has conducted studies using advanced techniques like the SAPHIR chamber for urban air simulations and molecular dynamics-guided reaction discovery to unravel complex oxidation processes. Their work bridges fundamental chemistry with applied environmental science, addressing critical gaps in understanding aerosol dynamics in both atmospheric and combustion environments.
Key contributions include investigations into sulfuric anhydride formation, ozonolysis of biogenic compounds (e.g., α-pinene), and the role of traffic-emitted amines in new particle formation. Awards and grants are not explicitly mentioned in the provided texts. Shawon collaborates with the Aerosol Physics research unit and has published extensively on topics like VOC oxidation, radical mechanisms, and the interplay between ozone and organic compounds in aerosol precursor formation.
