Top Countries in Nanotechnology Publications: Quality and Quantity at a Glance (2017-2021)
The overall position of the leading countries in nano-science publications, both quantity- and quality-wise, is illustrated in this infographic.
As is made evident by the size of the bubbles in this infographic (illustrating the total number of nano-articles published by each country), China, the United States, India, Iran, and South Korea possessed the largest volumes of nano-articles published in 2017-2021, respectively.
In terms of the H-index, China, the USA, Australia, Singapore and Germany ranked first to fifth, whereas regarding the average citation per nano-articles over the last 5 years, it is Singapore, Australia, the USA, and Switzerland which are leading.
As can be seen, apart from the United States and China, the position of countries such as Australia, Switzerland, and the Netherlands indicates a greater amount of emphasis being placed by their researchers on higher-impact scientific achievements; this is while countries such as Russia, Mexico, and even India are not in a very favorable situation as regards this indicator.
