The total number of times all records have been cited: This field displays the total number of citations to all of the nanotechnology-related articles in the set of search results.
This field displays the h-index count and is based on a list of publications ranked in descending order by the Times Cited count. The h-index is the number of the item/publication in the h rank of the mentioned ranking that has at least "h" citations. For example, an h-index of 20 means 20 items have 20 citations or more. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.
It is the average number of times the nanotechnology articles published within a year have been cited in the Journal Citation Reports.
