The 1st edition of Research.com ranking of the best universities in the arena
of Chemistry was created using data combined from
a wide range of data sources including OpenAlex and CrossRef. The bibliometric data for
estimating the citation-based metrics were collected on 06-12-2021.
Position in the ranking is based on a sum of D-indexes (Discipline H-index) of all ranking
scholar’s affiliated with a given institution. D-index
takes into account only publications and citation
metrics for an examined discipline.

The range of our Chemistry research
Research.com’s best universities ranking is a trustworthy account of
leading researchers from the field of Chemistry ,
established by means of a detailed study
of 166,880 scholars determined from
a variety of bibliometric data sources. For the field of
Chemistry, as many as 35760 researchers were
analysed.
What is D-index approval threshold for Chemistry
The D-index threshold for approving a researcher to be
examined is placed at 40 if
the majority of of their publications are in the area of Chemistry. The
inclusion requirements for scholars to be
considered into the ranking of top scholars are based on the D-index,
ratio of the publications made within the given
field of study as well as the awards and achievements of the
researchers. The D-index threshold for including best
scientists 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 researchers are added into the ranking.
There should be a proximity of 30% or less between a
researcher’s general H-index and their D-index.
Additional verification methods
As our main mission is to ensure that only
genuine scientists are included in
our ranking we believe that metrics are never
meant to be a full means to evaluate the
contributions of researchers. Because of that
we manually check every profile and cross-correlate it against publications in a
varied range of credible sources. Although it’s not a
element impacting a scientist’s position in
the ranking, the number of documents published in
well-known journals and conference proceedings should be a
credible secondary implication of their contribution to research in a
specific field of study. Position in the ranking is
determined by every researcher’s D-index
using information collected from OpenAlex and
CrossRef, which are the most prominent and well-established bibliometric
databases of this kind accessible to the research community. A
detailed definition of our research policy
can be found on our
methodology page.
Our mission
Our objective is to inspire researchers,
entrepreneurs and politicians
around the world to examine where prominent experts are heading
and to offer a way for the entire scientific community to
get to know who the leading experts in specific
areas of study, in various countries, or even within research
institutions are.
