Five year h-Index of nanotechnology publications

This indicator displays the h-index count and is based on a list of publications published during a 5-year period that ranked in descending order by the Times Cited count.

h-Index of nanotechnology publications

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.
