Top 20 States in Publication of Nanotechnology Articles

Statnano released statistics about the top 20 countries in publication of nanotechnology articles in 2013. China, the United States and India are the three top countries in publication of nanotechnology-related articles in 2013.

Based on the statistics which were obtained late January 2014 from the ISI Web of Science Database, China, the United States and India ranked first to third among the countries that produced the highest number of nanotechnology articles in 2013. The United States and China are still two giant nanoscience producers and they have published almost half of nanotechnology articles in 2013.

India has had the biggest growth among the top 20 countries, and by ascending three levels higher of where it was in 2012, it ranked third in 2013. South Korea showed one level upgrade and it ranked fourth in the world. Germany, Japan, and France are the next countries in this ranking. Iran is still in the eighth position although it showed an increase of 13.4% in comparison with the previous year.

The following table lists the top 20 countries in publication of nanotechnology articles.
