This special supplement to Science collects together summaries of both current and previous quality research conducted at Tianjin University and supported by the "973" Program, a central government funded initiative initiated by the Chinese Ministry of Science and Technology in June 1997. Its primary goal is to promote the advancement of science and technology in China, emphasizing basic and applied research that is aligned with national interests that will support national economic and social development. The program covers a very diverse range of research areas, from nanotechnology to energy efficiency to agriculture. Although the research covered in this supplement is only a sample of the many projects at Tianjin University, it is intended to provide the reader with a sense of the diversity and depth of work being performed under the "973" Program. As this program grows in the future, further scientific and technological advances will no doubt be forthcoming that benefit not only China and its people, but also researchers and citizens around the world.
