Unambiguous identification of N-containing oxygenated organic molecules using a chemical-ionization Orbitrap (CI-Orbitrap) in an eastern Chinese megacity

Autor: Y. Lu, Y. Ma, D. D. Huang, S. Lou, S. Jing, Y. Gao, H. Wang, Y. Zhang, H. Chen, Y. Chang, N. Yan, J. Chen, C. George, M. Riva, C. Huang

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 3233-3245 (2023)

Oxygenated organic molecules (OOMs) are dominated by the N-containing species in polluted urban environments. As N-containing OOMs, especially those with more than one nitrogen atom, prevail in the high m/z (mass-to-charge) range (m/z> 350 Th), unamb

Real-time measurement of phase partitioning of organic compounds using a proton-transfer-reaction time-of-flight mass spectrometer coupled to a CHARON inlet

Autor: Y. Peng, H. Wang, Y. Gao, S. Jing, S. Zhu, D. Huang, P. Hao, S. Lou, T. Cheng, C. Huang, X. Zhang

Publikováno v: Atmospheric Measurement Techniques, Vol 16, Pp 15-28 (2023)

Understanding the gas–particle partitioning of semivolatile organic compounds (SVOCs) is of crucial importance in the accurate representation of the global budget of atmospheric organic aerosols. In this study, we quantified the gas- vs. particle-p

CLASSIFICATION AND IDENTIFICATION OF ARTIFICIAL LAKES BASED ON NATIONAL GEOGRAPHIC-CONDITIONS DATA

Autor: Z. Zhou, S. Jing, Y. Gong, H. Zhao

Publikováno v: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol V-4-2021, Pp 187-192 (2021)

In recent years, the issue of violations or over-exploitation in artificial lake projects have attracted gradual concern. In the initial stage, in order to determine whether there are violations or over-exploitation in the artificial lake project, it
