Editorial

We convey our sincere thanks for the publication of this special University of Michigan issue of Chinese Chemical Letters. The idea to publish this special issue came from a meeting between Dr. Zhan Chen （Professor of Chemistry at the University of Michigan） and Dr. Huanfang Guo （associate editor-in-chief, Chinese Chemical Letters） when Dr. Guo visited the University of Michigan during May 2014. On behalf of Prof. Xuhong Qian, the editor-in-chief of Chinese Chemical Letters, Dr. Guo invited Prof. Chen to contact various professors at the University of Michigan to make contributions to a special issue. Prof. Chen received many immediate responses, resulting in the eighteen mini-reviews and research papers published in this issue and authored by members of research groups at the University of Michigan. Nineteen professors, their postdoctoral fellows, students, and collaborators contributed to this special issue, including professors associated with College of Literature, Science and Arts （Chemistry, Biophysics, Applied Physics）, College of Engineering （Chemical Engineering, Electrical Engineering）, School of Medicine （Radiology, Internal Medicine, Surgery）, School of Pharmacy, and School of Dentistry at the University of Michigan. The co-authors for these articles also include many researchers from universities in China such as Nanjing University, China University of Geosciences, Nanjing Medical University, Nanjing College of Chemical Technology, and Southeast University. The research reported in these articles covers many areas in chemistry and related sciences, as well as many interdisciplinary research projects, fitting the nature and scope of Chinese Chemical Letters, which publishes mini-reviews and research articles in all areas of chemistry, satisfying a real and urgent need for the dissemination of new and exciting research results.
