Almost 52% of the whole nanotechnology articles of 2017 were published by China, the United States, and India. This amount raises up to 62% for the first five countries. Likely to notice that these countries are the first options of scientific collaboration together. For example, 10% of China nanotechnology articles were published in partnership with USA or India have the highest scientific collaboration with USA and South Korea. The below chart shows the normalized share of the top 10 countries in nanotechnology publications.
China's ranked first as the last few years by publishing more than 56000 nanotechnology articles and USA the second, with more than 24000 articles. China's nanotechnology articles include nearly 17% of all of the articles of China while it's 6% for the United States. India, Iran, and South Korea are among the first five countries in this index by releasing 12600, 8800, and 8700 articles respectively. Iran ranked 6th after the South Korea, and Germany in the same index last year. The table below represents the number of articles of the first twenty countries and the share of nanotechnology articles among all of the articles. The mentioned share can be considered as a criteria of national priority of countries in the field of nanotechnology publications.
