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

摘要

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