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 agenda
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.
