séminaire de Xiaofeng Tang

Xiaofeng Tang, professeur au Anhui Institute of Optics and Fine Mechanics à Hefei (Chine), invité CaPPA, au PC2A.

Xiaofeng Tang is a professor at Hefei Institutes of Physical Science, Chinese Academy of Sciences. He got his Ph.D. from University of Science and Technology of China in 2011, and after that performed postdoctoral researches at National Synchrotron Radiation Laboratory at Hefei, and at Synchrotron SOLEIL in France. In 2015, he returned back to China. His present research is mainly focusing on vacuum ultraviolet (VUV) photoionization mass spectrometry and its applications, particular in atmospheric chemistry. His research has been approved from National Science Foundation of China, Ministry of Science and Technology of China, as well as Chinese Academy of Sciences. He has developed several novel VUV photoionization mass spectrometers and published more than 80 papers in peer-reviewed journals.

In this seminar, Dr. Tang will introduce their home-made VUV photoionization time-of-flight mass spectrometers, to detect or analyze ambient volatile organics (VOCs), key radicals involved in atmospheric chemistry, and chemical compositions of aerosol. He will also present their recent research progress on peroxy radicals by using synchrotron radiation-based photoionization mass spectrometry (PIMS, at Hefei) and double imaging photoelectron photoion coincidence spectroscopy (i²PEPICO, at SOLEIL).
