After starting to compile one of the growing subject areas of “Energy” under Advanced Materials research in the previous time, we have extracted the data in accordance to cover “Nanomaterials” for the current issue. Herein, we collected the data for last ten years and separated into 1) beginning of five years and 2) latter five years. The comparative research progress of “Nanomaterials” has been achieved at two time intervals through last ten years. In this respect, we discuss the variations in the document types and subject area (Fig. 1) meanwhile we also present the variation in the ranking of top-ten countries working in the field. As seen in Fig. 1, the percentages of research articles and reviews increased while those of conference papers, book chapters and books decreased, which indicated that the researcher has mainly focused on publishing results as soon as possible and the massive data production forced them to write much more review articles in order to compile researches and update knowledge. Furthermore, we have observed that 74% of all documents have been published for last five years while publishing 2.8, 3.5, 1.8, 2.7 and 1.3 folds of the results as article, review, conference paper, book chapter and book, respectively. In addition, the figure implied that the authors’ interest have shifted from fundamental to applied researches due to the fact that the percentages of chemistry, engineering, physics and astronomy decreased while chemical engineering, biochemistry and molecular biology, energy, medicine and environmental science significantly increased. The country ranking for “nanomaterials” and “advanced materials” field has varied through last ten years. South Korea and India jump up in the world ranking list as one and two-step up, Japan felt three-step down. We have also extracted the numbers of citations and h-indexes for top-ten countries. The citations and h-indexes are almost parallel to the amount of the data produced by each country. But, there are significant variations in cases of India and Australia, which emphasized the impact and popularity of the data published. Finally, we have collected and presented the data for top-ten affiliations and top-ten authors for each country in respect to the data searched as “nanomaterials” under “advanced materials” in all-fields for 2011-2015.
