The 2nd edition of Research.com ranking of the best researchers in the
discipline of Materials Science was created using data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
acquired on 21-12-2022. 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 scope of our Materials Science research
Research.com’s best scholars ranking is a credible list of leading researchers from the field of Materials Science, established by means of a meticulous analysis of 166,880 scientists determined from various bibliometric data sources. For the area of Materials Science, over 17130 researchers were examined.
What is D-index approval threshold for Materials Science
The D-index threshold for including a scholar to be evaluated is placed at 40 if most of their publications are in the area of Materials Science. The inclusion factors for scientists to be considered into the ranking of top researchers are based on the D-index, proportion of the contributions made within the given field of study as well as the awards and achievements of the scientists. The D-index threshold for including leading researchers is set as an increment of 10 depending on the total number of scientists projected for each discipline whilst guaranteeing that the top 1% of leading scholars are added into the ranking. There should be a proximity of 30% or less between a scientist’s general H-index and their D-index.
Other verification practices
As our main aim is to ensure that only credible scientists are included in Research.com ranking we realize that numbers are never supposed to be an absolute means to assess the work of researchers. Because of that we manually check each profile and cross-correlate it against publications in a varied range of credible sources. Even though it’s not a metric impacting a scholar’s position in the ranking, the number of documents published in well-known journals and conference proceedings should constitute a reliable secondary indication of their contribution to research in a selected discipline. Position in the ranking is established using each researcher’s D-index using data compiled from OpenAlex and CrossRef, which are the most prominent and well-known bibliometric databases of this kind available to the research community. A thorough explanation of our research process can be found on our methodology page.
Our aim is to motivate scholars, businessmen and administrative bodies around the world to examine where leading experts are heading and to offer a way for the entire scientific community to find out who the leading experts in specific areas of study, in different countries, or even within research institutions are.
