Institute of Material Science and Engineering of Chinese Academy of Sciences (NIMTE,CAS)

The Institute of Material Science and Engineering of Chinese Academy of Sciences (NIMTE,CAS) was found in Ningbo at 2006.

Data Source

In this study, the main data source of In this study, the main data source of analysis was derived from the WOS analysis was derived from the WOS (including SCI & ISTP) database and (including SCI & ISTP) database and Engineering Village (EI) database. Engineering Village (EI) database.

The retrieve word was the name of the The retrieve word was the name of the institute, the retrieve time period starts institute, the retrieve time period starts from 2006 to 2010 and the retrieve time is from 2006 to 2010 and the retrieve time is September 1st, 2010.September 1st, 2010.

The total effective number of the thesis The total effective number of the thesis involved is 428.involved is 428.

Outputs 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 gotten 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 got 169 articles at last. Because of the limitation of the retrieval time, the data in 2010 is partial.

Research Subjects

NIMTE have six business unites such as polymers and composites, magnetic materials and advanced devices, surface engineering & remanufacture, functional materials and nanodevices, fuel cell & energy technology and fibers. Most published papers concentrated on materials, physics and chemistry science of common subject catalogue for that NIMTE researchers’ education background involves in the above branch of learning.

International cooperation

NIMTE has paid an extraordinary attention to it and have already achieved great successes. NIMTE involved in diverse international activities, such as cooperate with U.S.A, Japan and Australia, actively communicating with world-famous institutes.

Research organization

From the SCI article we can also found that its authors from China have a strong connection with the advanced research organization in turn from USA, Japan and Australia, etc. This kind of collaboration leaded demotic research of CAS rapidly to the world class research level.

Number of SCI Articles Cited

There are 231 SCI articles published from 2006 to 2010, among which many thesis were cited by other papers. 1 to 5 time cited articles take part in 37%, 6 to 10 is 3%, 11 to 15 is 3%. It is significant that the most cited article was cited 35 times, which published in LANGMUIR, 23 (19): 9802-9807 on SEP 11 2007, and the work is mainly involve in silver hierarchical bowl-like array.

Number of Articles in SCI,ISTP,EI by NIMTE

Some experts of NIMTE published excellence work on SCI covered journals for many times since joining in the institute. Others published their papers in the journal included in EI. More than one scientist published over 20 SCI articles and over 10 EI articles, which showed that some scholars whose were so fruitful and NIMTE attract some hardworking experts.

By co-words analysis it can be found that NIMTE lucubrate on the microstructure & nanostructure materials these years, the ZnO or magnetic material (coercivit) will become the next hotspot the NIMTE scientists concentrate on.

Number of Patents

Totally 123 patents were got from the SIPO of P.R.C among the year 2005 to 2010.The patents date was collected from China intellectual properties net using the CNIPR software to analysis. Patent application increased sharply after 2007 and authorized patents after 2008.

Conclusion Bibliometric analysis and knowledge mapping w

ere applied to research the scientific productivity of SCI, EI, ISTP articles and patents of NIMTE, CAS from 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. This institute has already formed five patents group in past few years which can be illustrated from the knowledge map and bibliometric analysis results.
