Professor Kihong Park's paper was selected as one of the top 10 best scientific papers published by the US Aerosol Science and Technology in 2016-2017

□ Professor Kihong Park of the School of Earth Sciences and Environmental Engineering at the Gwangju Institute of Science and Technology (GIST, President Seung Hyeon Moon) wrote a paper that was selected as one of the 10 best papers published by the US Aerosol Science and Technology in 2016-2017.

∘ The editorial department of Aerosol Science and Technology recently reviewed all the papers published in 2016-2017 and selected 10 excellent papers. Among them, Professor Kihong Park's paper was the first best paper in the journal.

□ In the paper, Professor Kihong Park and his research team developed a system that grasped the chemical elements of fine dust particles in real time by combining laser technology and spectroscopic technology. Particularly, in order to improve the detection efficiency of the laser particle, a scattering laser control system was developed. As a result, the efficiency of detecting particle size of less than 1 μm was increased by more than 26 times compared to conventional methods, and chemical analysis of the molecules was made possible.

∘ Physicochemical properties of fine dusts analysis in real time provide the most basic data to quickly identify the source, origin, migration characteristics, climate change and health effects of fine dusts, but developing a device to analyze chemical characteristics of particles has been difficult.

□ Professor Park said, "This technology can be used for the real-time detection of various heavy metals in airborne fine dust, which is expected to contribute to the quick identification of harmful components and their sources of origin."

□ Professor Kihong Park master's student Hyeon-ok Myeon conducted this research through support from the Korean government and Samsung.
