This ranking is by citations per paper (impact) among those institutions that have collected 10,000 or more citations. This two-pronged analysis seeks to reveal the “heavy-hitters”; in doing so, it turns up some smaller producers with outsized influence.
For papers with multiple institutional addresses, each institution receives full, not fractional, credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 631 institutions are listed in the field of materials science, meaning that a total of 63,100 institutions were surveyed to obtain the results. Of the 631, 71 institutions collected 10,000 or more citations.
US institutions dominate the ranking, taking 15 of the 20 spots. IBM Corporation is here considered as a global institution. The Netherlands, Germany, the UK and France, in that order, complete the list, with one institution from each country.
This ranking may be compared with a similar one of two years ago. New to the top 20 are Rice University, the University of Groningen, Princeton University, Stanford University, the University of California, Los Angeles and the Georgia Institute of Technology. Dropping out of the list are the US National Institute of Standards and Technology, Pennsylvania State University, the University of Toronto, Ecole Polytechnique Fédérale de Lausanne, the Japan Science and Technology Agency and the University of Illinois.
