Long Yan is a researcher at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences. He graduated from the Department of Physics, Henan University, in 1996 with a Bachelor’s degree, from the State Key Laboratory of Superhard Materials, Jilin University, in 1999 with a Master’s degree, and from the Institute of Physics, Chinese Academy of Sciences, in 2002 with a doctorate. From 2002 to 2004, he worked as a Postdoctoral Fellow at the Max Planck Institute for Microstructure Physics in Germany. From 2004 to 2006, he worked as a Research Fellow at Yonsei University in South Korea. From May to August 2016, he worked as a Senior Visiting Scholar at the Massachusetts Institute of Technology in the United States. From 2006 to 2012, he worked as an Associate Researcher at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences, and has been a researcher since 2013. He is mainly engaged in research related to the regulation of the structure and properties of nanomaterials, the modification of new structural–functional materials, and the service behavior and evaluation of materials. In recent years, he has gradually focused on the research of carbon-based nanomaterials and material modification based on molten salt technology.
