On May 25, Jiaqi published her first paper in AE. She setup the ROS protocol in the lab with the help from Dr Ma Shexia （马社霞） of South China Academy of Environmental Sciences, and looked at the contributions from different sources to ROS in aerosol in Bangkok, Thailand. The sampler was setup in the air station on Kasetsart University（泰国农业大学） campus in urban Bangkok, by Haoyu. Students in Kasetsart University helped in sample collection which last for a round year. The original idea was to skip the ROS-related mechanism but using statistic tools to apportion the contributions. She made it. Congratulations!
