Top 20 Countries in Nanotechnology Publications

Over nine percent of all scientific articles published in 2014 are allocated to nanotechnology, and China, USA and India have published the highest number of ISI-indexed nanotechnology articles in 2014.

According to the statistics published in StatNano website, approximately 1.3 million articles have been indexed in Web of Science Database in 2014, among which about 9% are related to nanoscience and nanotechnology.

China still possesses the first rank and has distanced from other countries by having continuous growth in the number of ISI-indexed nanotechnology articles. More than one-third of nanotechnology articles have been published by the Chinese researchers while the American and Indian researchers possess the second and third ranks by publishing 17.3% and 7.3% of the nanotechnology articles, respectively. Table 1 presents the top 20 countries in the production of nanoscience. Saudi Arabia has had the largest growth in this regard since 2013 by having a growth of 31%, which results in possessing the 19th rank in 2014 while it ranked 23rd in 2013. After Iran, Saudi Arabia possesses the second rank in the production of nanotechnology articles among the Islamic countries. India has had the second largest growth after the Saudi Arabia by having a growth of 12%.

An observation to the ratio of nanotechnology articles to all scientific articles (Local Share) published by various countries shows that similar to the previous years, the Asian countries pay more attention to nanotechnology. As is seen in Table 3, there are eight Asian countries among the top 10 countries in this indicator. Moldova, Iran and Singapore possess the first to the third ranks in this ranking.
