Our investigations involve the fundamental science problems of Mars, Moon, Venus, Europa, and Enceladus. We use molecular and atomic spectroscopy, including Raman, IR, and Plasma spectroscopy, in our study. The design and building of planetary simulation chambers is another emphasis of this team.

Following are the five areas of our studies, and the relevant publications.

1. Heterogeneous Electrochemistry induced by Martian dust events,  Venus lightning, and radiolysis on Europa and Enceladus

  • Biomarker destruction caused by radiolysis on Europa (Wang et al., 2020, 2023)
  • CO2, N2, and SO2 breakdown products, pathways, and rates  by electric activities under Venus atmospheric conditions (Qu et al., 2020, 2021, 2022, 2023)
  • Amorphization of S, Cl-salts, and oxidation of Fe, S-species by heterogeneous electrochemistry on Mars (Wang et al., 2020)
  • Cl-release from common chlorides by heterogeneous electrochemistry on Mars (Wang et al., 2020)
  • Formation of chlorates and perchlorates by heterogeneous electrochemistry (Wang et al., 2017b2018; _Wu_2018)
  • Experimental investigation of simulate ESD in simulation chambers (Wu et al., 2016Yan et al., 2017Yan et al., 2018; Yan  et al. 2020, 2023)
