The 2nd edition of Research.com ranking of the best scientists in the
field of Chemistry was created using data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
scientist's D-index (Discipline H-index), which
only includes papers and citation
data for an examined discipline.
The range of our Chemistry research
Our best scholars ranking is a trustworthy list of leading researchers from the area of Chemistry, created using a detailed analysis of 166,880 scientists identified from various bibliometric data sources. For the area of Chemistry, over 43178 scientists were analysed.
What is D-index inclusion threshold for Chemistry
The D-index threshold for approving a researcher to be considered is placed at 40 if the majority of of their publications are in the field of Chemistry. The acceptance requirements for scientists to be considered into the ranking of top scientists are based on the D-index, ratio of the contributions made within the selected area plus the awards and achievements of the scholars. The D-index threshold for considering top researchers is set as an increment of 10 depending on the overall number of scientists assessed for each discipline whilst ensuring that the top 1% of leading scientists are considered into the list. There should be a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification practices
Since our main mission is to make sure that only genuine scholars are included in Research.com ranking we realize that metrics are never supposed to be a complete means to quantify the work of scientists. Because of that we manually verify each profile and cross-correlate it against publications in a broad range of credible sources. While it’s not a metric contributing to a scholar’s position in our ranking, the quantity of papers published in prominent journals and conference proceedings should be a reliable secondary implication of their contribution to research in a selected field of study. Position in the ranking is established using every scientist’s D-index using information collected from OpenAlex and CrossRef, which are the most credible and well-established bibliometric databases of this kind accessible to the research community. A comprehensive explanation of our research procedures can be found on our methodology page.
Our mission is to motivate researchers, businessmen and decision-makers worldwide to investigate where top experts are heading and to offer an opportunity for the whole research community to find out who the leading experts in specific fields of research, in various countries, or even within research institutions are.
