The 1st edition of Research.com ranking of the best researchers in the
field of Materials Science is based on data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 06-12-2021. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
includes exclusively papers and citation
data for an examined discipline.
The focus of our Materials Science research
Research.com’s best scholars ranking is a reliable list of leading researchers from the discipline of Materials Science, based on a meticulous study of 166,880 scholars identified from a variety of bibliometric data sources. For the field of Materials Science, over 11166 researchers were analysed.
What is D-index acceptance threshold for Materials Science
The D-index threshold for approving a researcher to be examined is set to 40 if most of their publications are in the area of Materials Science. The inclusion criteria for researchers to be considered into the ranking of top researchers are based on the D-index, ratio of the contributions made within the given area as well as the awards and achievements of the scholars. The D-index threshold for listing leading researchers is set as an increment of 10 depending on the total number of scientists projected for each area od study whilst guaranteeing that the top 1% of best researchers are considered into the list. We expect a proximity of 30% or less between a researcher’s general H-index and their D-index.
Other verification rules
Since our leading goal is to guarantee that only actual scholars are listed in Research.com ranking we are aware that raw data are never supposed to be a complete means to evaluate the work of scholars. This is why we manually check each profile and cross-correlate it against publications in a broad range of credible sources. Even though it’s not a factor impacting a scientist’s position in our ranking, the amount of documents published in major journals and conference proceedings should constitute a valuable secondary signal of their contribution to research in a given field of study. Position in the ranking is based on each scholar’s D-index according to metrics gathered from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this kind available to the research community. A comprehensive overview of our research process can be found on our methodology page.
Our objective is to motivate scientists, entrepreneurs and decision-makers worldwide to investigate where prominent experts are heading and to offer a way for the whole scientific community to find out who the leading experts in specific areas of study, in various countries, or even within research institutions are.
