The 2nd edition of Research.com ranking of the best scientists in the
discipline of Chemistry relies os data
derived from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
includes exclusively publications and citation
values for an examined discipline.
The scope of our Chemistry research
Our best scholars ranking is a credible account of leading scientists from the discipline of Chemistry, created using a thorough examination of 166,880 scientists determined from a variety of bibliometric data sources. For the discipline of Chemistry, more than 43178 scientists were investigated.
What is D-index inclusion threshold for Chemistry
The D-index threshold for approving a researcher to be evaluated is established at 40 if the majority of of their publications are in the field of Chemistry. The acceptance factors for scholars to be considered into the ranking of top scholars are based on the D-index, proportion of the contributions made within the selected area plus the awards and achievements of the scholars. The D-index threshold for listing best scholars is set as an increment of 10 depending on the overall number of scientists estimated for each scientific field whilst making sure that the top 1% of best scholars are added into the list. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Extra verification rules
Because our primary goal is to ensure that only credible researchers are included in Research.com ranking we believe that metrics are never meant to be a complete means to evaluate the output of researchers. This is why we manually check every profile and cross-correlate it against publications in a wide range of credible sources. Although it’s not a factor contributing to a scientist’s position in Research.com ranking, the number of papers published in prominent journals and conference proceedings should form a credible secondary implication of their contribution to research in a given discipline. Position in the ranking is based on every researcher’s D-index with the help of information collected from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this type open to the scientific community. A comprehensive overview of our research policy can be found on our methodology page.
Our aim is to motivate scientists, companies and decision-makers worldwide to explore where top experts are heading and to give an opportunity for the whole research community to get to know who the leading experts in specific disciplines, in different countries, or even within research institutions are.
