Institutions are positioned in the ranking based on the aggregate D-indexes (Discipline H-index) of all ranking scholars whose primary field of publication is Chemistry and who are affiliated with the institution. The D-index represents a measure of scientific productivity and citation impact, factoring in only those publications and citations specific to the examined discipline (Chemistry) for each scholar.
Scope of Research
This ranking is founded on an extensive analysis of 279,971 scientist profiles identified from a diversity of bibliometric databases. Of these, 279,971 scientists were specifically examined for their contributions in Chemistry. A stringent D-index threshold of 40 was set for inclusion, ensuring that only scholars with a substantial impact in Chemistry, as defined by a majority of their tier publications in the field, were considered.
In addition to bibliometric indicators, scientists' awards and achievements in Chemistry were also evaluated as part of the ranking process. The D-index threshold for identifying top researchers is dynamically adjusted in increments of 10, tailored to the total number of scholars within each discipline. This process ensures that the ranking inclusively represents the top 1% of leading scholars globally. Further, to maintain field relevance, a proximity of 30% or less between a scientist’s overall H-index and their D-index was mandated. Scholars' distinctions and noteworthy contributions also played an integral role in final ranking determinations.
Verification and Validation Practices
The team behind the Research.com ranking recognises the inherent limitations of raw bibliometric data as a means to evaluate scholarly output. To address these, all scientist profiles included in the ranking underwent rigorous manual verification and cross-checking against a broad array of authoritative publication sources.
While not a direct contributing factor to a researcher's position in our rankings, the volume of articles published in prominent journals and conference proceedings serves as a valuable supplementary indicator of a researcher’s influence and activity within a particular scientific domain.
The final ranking is determined using each researcher's H-index based on data from OpenAlex and CrossRef—undoubtedly among the most prominent and trusted bibliometric databases globally. This robust methodological approach ensures accuracy and integrity in representing academic outputs.
