Li Zhongjin, Professor: Born in 1946, graduated from Peking University Department of Chemistry 1970. Doctoral supervisor of School of Chemistry and Chemical Engineering, Shaanxi University of Science and Technology (natural polymer material modification and environmental science direction), professor and discipline leader of School of Chemistry and Chemical Engineering, director of Institute of Applied Chemistry, director of teaching and research section of inorganic and analytical chemistry, deputy director of inorganic professional committee of Shaanxi Chemical Society, member of thermal professional committee of Shaanxi Metrology Society. Mainly engaged in the modification research of natural polymer materials. In 2005, the general project of the National Natural Science Foundation: "Study on Quantitative Degradation Mechanism and Controllability of Starch Ball" was supported by 260,000 yuan. He presided over the synthesis and application of starch microspheres, the modification of gelatin microcapsules, bone glue adhesives, and new and improved water retaining agents. Its projects have won the support of provincial and municipal education departments for many times, presided over one national natural science fund and completed two national natural science funds. He presided over the completion of the "Tenth Five-Year Plan to tackle the development model of stress resistance and disaster reduction in the gully region of the Loess Plateau and the sub-projects of the Ministry of Science and Technology and the Ministry of Agriculture". 1998 "Study on High-yield Cultivation and Industrialization of Acer truncatum Bunge" won the second prize of Shaanxi Provincial People's Government for scientific and technological progress, and 200 1.3 was included in the "Ninth Five-Year Plan" national key scientific and technological research, which was a major achievement of forestry projects. In 2006, "the synthetic technical conditions and industrialization of corn starch microspheres" and "natural environment-friendly adhesive-this kind of bone glue" passed the appraisal one after another. Among them, "technical conditions for the synthesis of corn starch microspheres and its industrialization" has won the second prize of the Provincial Department of Education. Published 8 monographs including Inorganic Fine Chemicals, Experimental Methods of Polymer Science, Comprehensive Utilization of Packaging Wastes, Packaging Materials, Electronic Fine Chemicals, Selected 300 Practical Chemical Products, and Formulation and Technology of Small Chemical Products; He has published more than 200 scientific research papers in Science Bulletin and Journal of Chemistry of China University. In recent years, SCI has included 10 papers, successively applied for national invention patents 15, and successfully approved 10.
