 Introduction:

Tiangang Yang, research fellow, Department of Chemistry, South University of Science and Technology,doctoral supervisor,winner of Qiushi Young Investigator Award, and national leading talent of Shenzhen. Professor Yang received a bachelor’s degree and a doctorate from Dalian University of Technology in 2009 and 2015. 2016-2019 postdoctoral research at the University of California, Los Angeles (UCLA). Joined the chemistry department in South University of Science and Technology of China at the end of 2019 as the project leader. Since his research work, he has carried out a series of works on the role of reaction resonance in chemical reactions, the application of quantum tunneling effect in low temperature interstellar chemistry, and the molecular chemical kinetics of low temperature ions, and achieved a series of original results. He has published many articles in international journals such as Science, Science Advances, Nature Chemistry, etc.

Abstract:

low-temperature molecular chemical kinetics play an important role in atmospheric and interstellar chemistry. Understanding these chemical reactions is the basis for further understanding the formation and evolution of interstellar molecular clouds. However, how to effectively cool the ions or molecules involved in the reaction in the laboratory is a very challenging task, which also hinders the development of related experiments and theories. In this report, I’ll share how to design unique experimental devices to achieve controlled conditions for quantum states at low temperatures. Recently, we have developed a set of low-temperature molecular reaction devices by combining ion trap with laser-cooled ion technology and buffer gas-cooled molecular technology. The reaction of beryllium ion and carbon ion with water at low temperature was studied by using this device, and the kinetic characteristics of the reaction at low temperature were revealed.
