This project aims to assess the outcomes and impacts of 15 Nanotechnology Science and Engineering Centers (NSECs) in relation to the National Nanotechnology Initiative (NNI) objectives and goals. The study examines publication output, co-authorship patterns, geographical spread, multidisciplinarity, and industry collaborations. Various data analysis methods are used, including bibliometrics, network analysis, GIS, and qualitative analysis.

Program Level Assessment of Outcomes and Impacts of Research of Centers Juan D. Rogers School of Public Policy Georgia Tech Project: Assessment of 15 Nanotechnology Science and Engineering Centers’ (NSECs): Outcomes and Impacts: Their Contribution to NNI Objectives and Goals, NSF 0955089.
Objectives • Publication output and impact of the NSECs • Co-authorship patterns change over time • Geographical spread or concentration of NSEC research collaboration • Evolution of areas of research as reflected in keyword changes • Multidisciplinary footprint of the centers • The case for centers AEA, Annaheim CA
Methodology Outline • Qualitative-quantitative concurrent design • Qualitative component • Multiple embedded case studies of mechanisms for center outcomes • Follow up field level impact with quantitative analysis • Quantitative component • Bibliometrics (productivity, citation, co-authors, etc.) • Personnel and funding data analysis • Intellectual property instances (patents, licenses, etc.) • Links with business and commercial applications • Methodologically: Final results are generalizations to theory from qualitative analysis • We offer analysis of combined quant-qual data • Interpretive schemes for quantitative findings on centers AEA, Annaheim CA
Data and methods • Acquisition of 85 center annual reports from all 15 NSEC centers • Extraction and clean up (duplicate removal) of publication lists • Extraction of NSEC articles from Web of Science (n=3,500) • Look up and extraction of articles citing NSEC articles (n=75,000) • Clean up and classification of collaborating organizations • Clean up, look up, identification, and matching of NSEC authors in author listings • Analyses of different type, multiple tools: • Growth, shares, and overall trends (tabular) • Networks and collaborations (Gephi) • Geographical spread, GIS (ArcGIS) • Keywords and topics (VantagePoint) • Multidisciplinarity and science maps (Pajek) AEA, Annaheim CA

Comparative Impact of NSEC Papers (Citations Cohort 2001) AEA, Annaheim CA
Comparative Impact of NSEC Papers (Citations Cohort 2002) NSEC papers appear to have higher impact measured by citations: median and mean citations grow faster than the cohort with window length AEA, Annaheim CA
Rank in Cohort of Top 20 NSEC Papers NSEC papers rank highly in their cohort of Nano papers. Total Cohort 2001: 30462 papers. NSEC Cohort 2001: 66 papers Total Cohort 2002: 34971 papers. NSEC Cohort 2002: 128 papers AEA, Annaheim CA
Comparative Impact of NSEC Papers (Citations Cohort 2003) The distributions parameters show NSEC high position in the field but the top paper is still not by the centers. N = 40813 CN = 222 AEA, Annaheim CA
Comparative Impact of NSEC Papers (Citations Cohort 2004) N = 48952; CN = 259 AEA, Annaheim CA
Comparative Impact of NSEC Papers (Citations Cohort 2005) N = 55998; CN = 499 AEA, Annaheim CA
Comparative Impact of NSEC Papers (Citations Cohort 2006) N = 62351; CN = 512 AEA, Annaheim CA

Co-authorships NSEC co-authorship networks grow and become more widespread Co-authorships 2001-2006 Co-authorships 2007-2010 Notes: Nodes represent authors. Node size represents number of publications for the period. Node colors represent 15 NSEC centers. Line colors are those of the centers that maintain each co-authorship as found in publication databases. Source: ISI-WoS publication data based on NSEC annual reports by center. AEA, Annaheim CA
Co-authorships Multiple productive and collaborative authors NSEC collaboration networkspresent diverse patterns of co-authorship (2001-2010) Central and well connected authors Highly collaborative projects AEA, Annaheim CA
Collaboration and places Wide geographic spread of NSEC research with concentration in specific locations/regions Note: Number of NSEC publications from 2001-2010 = 3509; number of citing publications = 75335. Citing publications, 2001-2010 exclude all NSEC publications. AEA, Annaheim CA
Collaboration and places Co-authoring extends beyond the NSECs to nearly all US states AEA, Annaheim CA

Conclusions Implications for Center Policy • NSEC publication growth rate indicates rapid take-off by new centers. • NSEC mechanism allows for greater involvement of authors over time in diverse locations. • NSEC research involves some foundational as well as some emerging (and some maturing) topical areas. • NSECs work in multiple disciplines and their citation influence involves many more disciplines (especially in Biotechnology related fields). AEA, Annaheim CA
The Case for Centers • Reporting by PIs on crucial role of centers: • Unique incentive to go deeply across disciplinary boundaries • Significantly reduced cross-disciplinary transaction costs • Unique research experience for graduate students • Rich and diverse research infrastructure enables more risk taking • Exposure to greater number of high quality scientific contacts • Exposure to unique industry contacts • Accelerator of promising young researcher development • Center as recruiting tool of top talent • Diverse mentoring opportunities for rapid career development • Unique infrastructure possibilities • Leverage of resources for shared new facilities • Design of new unique instruments and experimental arrangements AEA, Annaheim CA
Some Program Challenges • Some scientific contributions are difficult to explain to the lay public • Important for long term support of the enterprise • The special benefits for development of faculty and graduate students should be scaled up to reach the rest of the university community • The pre- and extra- university education efforts are dependent on the center program and are difficult to institutionalize without it. • Their sustainability should be a program concern • Similar sustainability issue is raised by specialized infrastructure that may go to waste if centers are discontinued AEA, Annaheim CA
