Nanoscience and Nanotechnology in Scopus: Journal Identification and Visualization. 14th International Society of Scientometrics and Informetrics Conference, Vienna (Austria), 15th-19th July 2013 This document presents a new query for the retrieval of information about Nanoscience & Nanotechnology (N&N) based on the combination of previously published search strategies, contrasted by the scientific community. It led us to identify 80 core journals of N&N in Scopus, then map and analyze the underlying structure of N&N output using visualization techniques. N&N is established as a productive young discipline, crosscutting other fields in its rapid evolution, for which reason it has poorly defined limits to date, and needs some time to consolidate its identity as a discipline. Materials & Methods On 06/11/2012 we launched a search against the Scopus database using the combination of different queries proposed previously. Query 1 included terms with the root nano*, while excluding any terms containing the root nano* yet not related with N&N. To this end, we referred to the combination of proposals made by Noyons et al., 2003; Glänzel et al., 2003; Huang et al., 2003; and Meyer, Debackere and Glänzel, 2010. In turn, query 2 combined instruments and processes utilized in N&N with different types of materials, functions and other terms, in the wake of proposals by Noyons et al., 2003, Glänzel et al., 2003, Kostoff, Koytcheff and Lau, 2007 and Porter et al., 2008. Finally, query 3 included a series of terms related with N&N and was based on the work of Noyons et al., 2003; Glänzel et al., 2003; Huang et al., 2003; Kostoff, Koytcheff and Lau, 2006; Porter et al., 2008; and Lv et al., 2011. The combination of these three searches led to a new query which we believe can be perfectly adopted for the identification of N&N documents in any specialized or multidisciplinary database (Annex).
