Prof. Shi Changxu                            　　 Prof. Shi Changxu is a most famous material scientist in China. Prof. Shi was chief consultant of Directing and Coordinating Commission for Nano-Science and Technology of China. He received his Ph.D at University of Notre Dame and did Postdoctoral research at Massachusetts Institute of Technology in 1952. He is academician of Chinese Academy of Sciences, Chinese Academy of Engineering, and

   Third World Academy of Sciences. He was the director of Science and Technology
   Department of Chinese Academy of Sciences, vice director of Natural Science Foundation
   of China, vice president of Chinese Academy of Engineering, and the first Chairman of
   Materials Research Society of China. Now, Prof. Shi is the director of Consultant
   Committee of Chinese Academy of Sciences, the consultant of Natural Science Foundation
   of China, a member of the presidium of Chinese Academy of Sciences and China Academy
   of Engineering, and honorary superintendent at Metal Research Institute of Chinese
   Academy of Sciences. As a leading authority, Prof. Shi pays close attention to the
   development and growth of the Group. With his support, the Zhengguang Group is
   continually development in polymer materials and nano-technology.

     Prof. Ren Jizhou has gained the Third Class Prize of National Advanced Science and
  Technology one time, the First Class Prize of Provincial Advanced Science and
  Technology twice, the Second Class Prize four times, the Third Class Prize twice. He
  has published research paper abroad and home over 130 pieces. He has began to train
  postgraduates since 1955, and has already fostered 35 masters (including postgraduates
  before the Great Cultural Revolution ), 15 dotoral students, and now he is educating 7
  doctoral students.

　　base of water and soil conservation and shelterbelt network construction.

　　processing relationship of polymer and applications of polymer materials for a long
　　time, and put the theory to production. His theory, New Way on Stiffning and
　　Toughening of Polymer Materials, is highly recognized by the domestic and
　　international associates. Up to now, product development directed by his theory has
　　achieved exciting results and already gained several patents in China.

Prof. Liu Zhongren                            　　 Prof. Liu Zhongren graduated from Plastic Engineering Major of Sichuan University in 1964. He was studying the Structure and Quality of High Polymer Material in Loughborough University of Technology in England from the year of 1984 to 1986. In 1996, he went to Case Western Reserve University of America to make academic exchanges. The scientific study which was taken charge by Prof. Liu has been the second prize of

　　National Science and Technology Advancement of Educational Committee, the first prize
　　of Sichuan Science and Technology Advancement and prize of Sichuan Excellent New
　　Product. Prof. Liu has taken long time to engage in education and study of shaping
　　and processing of high polymer material. Under his direction, the item of nano-
　　polypropylene piping material has been successfully developed. It has passed the
　　Export Group Appraisal by Prof. Fosong Wang who is the vice-president of Chinese
　　Academy of Science and has been put in batch process. Prof.Zhongren Liu is vice-
　　engineer of Chengdu Zhengguang Sci & Tech Co., Ltd.
