On May 16, 2023, the Photonic Nose and Molecular Materials Group invited researcher Yuan Kaijun from Dalian Institute of Chemical Physics, Chinese Academy of Sciences, to give a presentation to group members in the lecture hall of the Institute of New Concept Sensors and Molecular Materials. The report was hosted by Prof. Bian Hongtao, and attended by teachers, doctoral and MS students of the group.

Yuan Kaijun’s research interests focus on interstellar and atmospheric related small molecule photochemical dynamics, as well as high-pressure ultrafast spectroscopy and two-dimensional infrared spectroscopy. He has built an experimental station for molecular photochemistry based on Dalian Coherent Light Source and realized full-band and full-channel high-resolution measurements of molecular photochemical products. His report focused on the use of Dalian Light Source to study the extreme ultraviolet photochemical kinetics of interstellar water molecules and hydrogen sulfide molecules, etc., and the implications of these results in interstellar chemistry. In addition, he also introduced the high-pressure micro ultrafast spectroscopy characterization system recently developed by his laboratory and its work progress on ultrafast dynamics of advanced materials.

After the report, Yuan Kaijun discussed with the students and faculty members about his report content, and took a group photo with them.
