On July 19th, Prof. Gengwen Tan from Sun Yat-sen University, Prof. Jingzhen Du from Zhengzhou University, and Prof. Shuai Guo from Capital Normal University visited our lab. The three professors toured various instruments and displays in the lab and took group photos with everyone. Prof. Gengwen Tan is currently with the School of Chemistry at Sun Yat-sen University. He has long been involved in the synthesis, characterization, and property research of novel main-group element compounds, recently focusing on monocoordinate main-group element compounds. Prof. Jingzhen Du is currently with the School of Chemistry at Zhengzhou University. He has long been involved in research on f-block metal-organic coordination chemistry and related fields. Prof. Shuai Guo is currently with the Department of Chemistry at Capital Normal University. He has long been involved in the research of metal-organic chemistry of N-heterocyclic carbenes. We appreciate the visit of the three professors!
