The ICMAB is the first center in the CSIC in terms of research outputs per capita, according to Nature Index

  • According to Nature Index, ICMAB is the first CSIC center in research outputs per capita in the ranking, and the second in terms of research outputs.
  • CSIC is the first research institute in Spain, and is ranked the 50th research institution worldwide, and the 4th government institution, in terms of research outputs. 

Nature Index: ICMAB, CSIC and Spain

The Nature Index database is an indicator to value the impact of the research outputs, and compare it to other research institutes of the world and within the CSIC. The Nature Index tracks the author affiliations collected fom high quality scientific articles published in 82 high-quality science journals independently selected by a panel of active scientists. 

In the recently updated Nature Index, based on published research articles from 1 August 2017 to 31 July 2018, ICMAB occupies the first position within the CSIC centers, in terms of research outputs per capita (per number of researchers). The second position among the CSIC centers is for the ICMM (Institute of Materials Science in Madrid), highlighting the high-quality of Materials Science research in Spain. Without normalizing the research outputs per number of researchers, the ICMAB occupies the second place, after the ICMM. 

CSIC is ranked the 48st position worldwide in the period August 2017-July 2018 and the 50th in the period January-December 2017, taking into account all type of scientific institutions. However, it is the 5th worldwide when counting only the government institutions. In Spain, CSIC is the first research institute, followed by the BIST and the UB. The UAB (Autonomous University of Barcelona) occupies the 8th position in the ranking. Spain is in the top 10 countries in the global ranking, out of 50.

Top ICMAB articles according to the Altmetric Attention Score

The Altmetric Attention Score is an automatically calculated, weighted count of all of the attention a research output has received. It is based on 3 main factors: volume, source, authors. Combined, the attention score represents a weighted approximation of all the attention for a research output (not a raw total of the number of mentions) in the press, Twitter, blogs, Facebook, etc. You can find more detail about how it’s calculated, including the standard weightings for each mention type, here. The attention score is useful when looking at several outputs together to quickly identify the level of online activity surrounding a particular research output – it is not a measure of the quality of the research, or the researcher.

The top articles by Altmetric score from ICMAB-CSIC in the year 2017 are the followsing: (they coincide with the articles that we have done press releases):

According to Nature Index 2018 Science Cities, an independent supplement of Nature journal, with bibliometric information extracted from Nature Index, which is monthly updated and with information from 82 journals. In the article "Peripherical forces" they analyze the growth of cities in terms of scientific research outputs. Barcelona is highlighted to grow 156 % between 2000 and 2013.


The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 82 high-quality science journals. The database is compiled by Nature Research. The Nature Index provides a close to real-time proxy of high-quality research output and collaboration at the institutional, national and regional level. The Nature Index is updated monthly, and a 12-month rolling window (1 August 2017 - 31 July 2018) of data is openly available at www.natureindex.com under a Creative Commons non-commercial license. Article output is counted in two ways: Article count (AC): where a count of one is assigned to an institution or country if one or more authors of the research article are from that institution or country, regardless of how many co-authors there are from outside that institution or country; Fractional count (FC): that takes into account the percentage of authors from that institution (or country) and the number of affiliated institutions per article. For calculation of the FC, all authors are considered to have contributed equally to the article. The maximum combined FC for any article is 1.0. The ratio of AC to FC gives an indication of the degree to which an institution or country collaborates in its research. Broadly speaking, if the AC is a lot higher than the FC it indicates a high degree of external collaboration and dependency on external resources. If the AC is close in value to the FC it indicates limited collaboration with external researchers and a strong dependency on internal resources.
