Dalian Institute of Chemical Physics (DICP), ChineseAcademy of Sciences (CAS) was founded in March, 1949. It is a multidisciplinary institute engaging in both fundamental and applied researches of chemistry and chemical engineering, especially with strong abilities for technological development. Over the span of half a century, DICP has conducted researches of many fields, all integrating closely with the needs of national economic reconstructions. It has developed its own features in catalytic chemistry, engineering chemistry, organic synthetic chemistry, chemical lasers and molecular reaction dynamics, as well as in modern analytical chemistry, especially in chromatography. A large number of achievements have been obtained, which have made important contribution in national economic reconstructions.
