On February 24, Professor John Wenger (University College Cork, Ireland) visited the Chongqing Institute for an academic visit via the invitation of Professor  Yang Chen (Director of the Research Center for Atmospheric Environment). The visit aimed to enhance international collaboration in atmospheric chemistry and promote the deep integration of academic research and global collaboration. During his presentation, Professor John Wenger introduced the smog chamber simulation reaction system at the Research Center for Atmospheric Chemistry (CRAC) of University College Cork.

He elaborated on the chamber characterization, including the main frame, the high-resolution online instrumental system, and the gas distribution system. He highlighted recent achievements in the study of the atmospheric oxidation mechanism of oxygenated monoterpene compounds and significant findings in the source apportionment of port ship emissions.

Both parties engaged in extensive discussions on strengthening academic exchange and collaboration, including the joint training of high-level talent, student exchange programs, academic and student visits, and establishing joint laboratories. They reached a broad consensus and committed to fostering deeper communication and cooperation.

University College Cork (UCC), founded in 1845, is a member of the "National University of Ireland" alliance. As one of Ireland's oldest and most prestigious universities, UCC is globally recognized for its excellence in research, innovation, and education, with world-class achievements in food science, medicine, and environmental science.

Professor John Wenger is a Fellow of the Royal Society of Chemistry, Vice Dean of the School of Chemistry at UCC, founder of the Atmospheric Chemistry Research Center, and head of the Atmospheric Processes and Air Quality research area at the Environmental Research Institute. With over 25 years of research experience in atmospheric chemistry and air quality, his primary research interests include the atmospheric degradation of VOCs and the chemical composition of atmospheric aerosols. He has published more than 110 papers in internationally renowned journals, with an H-index of 46 and approximately 10,000 citations (as of February 2025).
