1、Bibliometric analysis on scientific productivity of NIMTE,CAS,H.B.Qiu and P.H.Lui NSL,CAS,The Institute of Material Science and Engineering of Chinese Academy of Sciences (NIMTE,CAS) was found at Ningbo in 2006.,Introduction DaTa and MethodsResult Analysis,Introduction.,In this study, the main data

2、source of analysis was derived from the WOS (including SCI & ISTP) database and Engineering Village (EI) database. The retrieve word was the name of the institute, the retrieve time period starts from 2006 to 2010 and the retrieve time is September 1st, 2010. The total effective number of the thesis

3、 involved is 428.,Introduction,The data source came from WOS and EI, and the publish time span is from 2006 to 2010, updating in July 30, 2010. Data in this study was required on Sept 1st, 2010 using the Address= “Ningbo Inst Mat Technol & Engn” selecting “all the years”. Totally 231 articles are go

4、tten from the database as SCI-Expand and 27 articles as ISTP, which called Conference Proceedings Citation Index-Science (CPCI-S) now. For EI part, we turned to expert search of EI-compendex database using author affiliation retriever in all forms of NIMTE stored in Engineering Village Database and

5、got 169 articles at last. Because of the limitation of the retrieval time, the data in 2010 is partial.,Data and Methods,Number of Articles Number of PatentsMethods: using the subjects, collaboration(co-author ), publications, time-cited, co-words, cluster analysis,Number of Articles,Fig.1 Number of

6、 Articles during the period 2006-2010,AARG 93%,Patents,Fig.2 Number of Patents during the period 2005 to 2010,Applicants= Ningbo Institute of Material Technology and Engineering,The Number of Patents can show the scientific level of an institute and its investment in innovate.,Research Subjects,Fig3

Distribution of the Research

9、 Subjects,the patent mainly concentrates in exploring the technology on: “class C: Chemistry, Metallurgy” “class H: Electricity” IPC international patent classification. The research field owning most patent distributed on coating(涂料) technology (C23C), cell preparation (H01M) and organic polymer (C

Distribution of Number of Patents during the period 2005-2010,Patents,Most patents of NMITE were applied in 2008, which concentrated in cell preparation(细胞的制备) (H01M), organic polymer(有机聚合物) (C08G) and coating technology (C23C), while metallurgy(冶金) (C22C), oxide(氧化物) (C04B) and

11、 magnet materials (H01F) in 2009 as showing in figure 10. Patents application on coating technology (C23C) kept steadily after 2008.,Most patents of NMITE were Exclusive(独有) Patents, which account for 94.7%, while 5.3% of the patents were cooperated with its partners, which can be seen in table 2.,T

Distribution of Top 10 patents applicators from 2005 to 2010,Most of them applied their patents in the year of 2008 and 2009, The core technology of NIMTE developed rapidly in a short period since established.,Keywords are the main subject o

13、f one research paper concentrate on and through which one could clearly understand the topic or main idea of the publications. By Keywords analysing , we can be found the main field NIMTE lucubrate(深入研究) on.,A: SOFC(固体氧化物燃料电池 ),cell stack, cathode(阴极) B: vacuum chamber(真空室 ),device,diaphragm(隔膜) C:

14、preparative method, ERF(电流变液), titanyl oxalate(碱式草酸钛) D: Nd-Fe-B,alloy,material E: composite materials,fiber,preparative method,In this paper, the bibliometric analysis and knowledge mapping were applied to research the scientific productivity of SCI, EI, ISTP articles and patents of NIMTE, CAS from

15、 2006 to 2010. The published papers and applied patents grown rapidly during these years and the paper authors took extensively collaboration with many research organizations of the world. Some research subjects such as microstructure or nanostructure lead the main research field of NIMTE. The institute has already formed five patents group in past few years which can be illustrated from the knowledge map and bibliometric analysis results .,END,Thank You for Your Attention.Lecturer: HuaBing Qiu,
