The ISI subject categories classify journals included in the Science Citation Index (SCI). The aggregated journal-journal citation matrix contained in the Journal Citation Reports can be aggregated on the basis of these categories. This leads to an asymmetrical transaction matrix (citing versus cited) which is much more densely populated than the underlying matrix at the journal level. Exploratory factor analysis leads us to opt for a fourteen-factor solution. This solution can easily be interpreted as the disciplinary structure of science. The nested maps of science (corresponding to 14 factors, 172 categories, and 6,164 journals) are brought online at

Ageing of publications, percentage of self-citations, and impact vary from journal to journal within fields of science. The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-ISI journals are increasingly cornered into “transdisciplinary ” Mode-2 functions with the exception of specialist journals publishing in languages other than English. An “externally cited impact factor ” can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example.

2 Nano-biomedical science is a promising area in the application of nanotechnology. This paper profiles a group of 21 leading scientists in nanobiomedicine based on high publication rate and high citations. Comparisons with other researchers indicate that the leaders publish more in high impact journals and collaborate more extensively (team science). They reside most heavily in the USA and Western Europe. We compare their research publications using multiple indicators – integration, specialization and a multidisciplinary index. Relations among interdisciplinarity indicators generated support a 3-factor model based on principles of diversity. We locate this research among the disciplines using science overlay mapping. Key term analyses, based on keywords and on natural language processing (NLP) help profile the research emphases of these leading researchers. Such results could serve as leading indicators to help identify directions of future nano-bio development. 1.

This chapter explores whether and how the field of hybrid nanomaterials is interdisciplinary, with the aim of understanding the underlying knowledge structure of this book. To do so, we conducted a bibliometric analysis based on 113 review publications selected by the contributors. The results suggest that integration of different disciplines is carried out first, around research on specific inorganic support materials (quantum dots, carbon nanotubes, etc.), and second, around research on applications in sensing and molecular machines. The centrality of sensing applications and their pervasive presence in other clusters suggest that they constitute the key 2 integrative driver for interdisciplinarity in hybrid nanomaterials. The weak coherence of the field may possibly indicate that the field is in its early stages. Disciplinary diversity in hybrid nanomaterials is found to be higher than the norm in the chemistry disciplines in which it is embedded. The field draws mainly on disciplines from
