Figure 76: Citation rates for the subject category “nanotechnology” over time
The graphs that follow show the citation rates of the disciplines over time grouped according to
each country studied. This allows us to draw conclusions on the perception of countries in the
disciplines and to compare the impact of a discipline in the respective countries. Relatively small
numbers in the publication output are partially responsible for significant shifts. It can also be
seen, for example, that Iranian publications in multidisciplinary journals are only perceived to a
very limited degree and that the citation rate for this subject category is the worst of all of the
Iranian citation rates. In contrast to this, this subject category is top of the list for all of the other
countries analysed and at times must be placed on a secondary axis.
A drop in the citation rates as we approach the present is not unusual because newer
publications have had less time to be read and then cited in other subsequent publications.
