Abstract: | This article examines the relative positions with respect to nanotechnology research publications of the European Union (EU),
the United States (US), Japan, Germany, China, and three Asian Tiger nations (South Korea, Singapore, and Taiwan). The analysis
uses a dataset of nanotechnology publication records for the time period 1990 through 2006 (part year) extracted from the
Science Citation Index obtained through the Web of Science and was developed through a two-stage modularized Boolean approach.
The results show that although the EU and the US have the highest number of nanotechnology publications, China and other Asian
countries are increasing their publications rapidly, taking an ever-larger proportion of the total. When viewed in terms of
the quality-based measure of citations, Asian nanotechnology researchers also show growth in recent years. However, by such
citation measures, the US still maintains a strongly dominant position, followed by the EU. |
