The delineation of nanoscience and nanotechnology in terms of journals and patents: a most recent update

TL;DR

This paper updates the analysis of nanoscience and nanotechnology through journal and patent data, highlighting recent shifts in national contributions and the impact of new classification tags.

Contribution

It provides a recent overview of nanoscience and nanotechnology representation in journals and patents, emphasizing changes in national profiles and the introduction of new patent classifications.

Findings

USA's position decreased in 2005 compared to 2004

EU-27 gained in world share of citations

Introduction of 'Y01N' patent tag visualizes national profiles

Abstract

The journal set which provides a representation of nanoscience and nanotechnology at the interfaces among applied physics, chemistry, and the life sciences is developing rapidly because of the introduction of new journals. The relevant contributions of nations can be expected to change according to the representations of the relevant interfaces among journal sets. In the 2005 set the position of the USA decreased more than in the 2004-set, while the EU-27 gained in terms of its percentage of world share of citations. The tag "Y01N" which was newly added to the EU classification system for patents, allows for the visualization of national profiles of nanotechnology in terms of relevant patents and patent classes.
