A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the publications and citation counts relevant to the specific discipline under examination—in this case, Chemistry. This focused approach ensures that the ranking faithfully represents scholarly impact within the domain rather than general research productivity.
Scope of Research and Eligibility Criteria
The ranking is derived from an analysis of 279,971 scientist profiles identified from a variety of bibliometric databases spanning all scientific disciplines. From these, 71 scientists specializing in Chemistry within Russia were examined in detail. To qualify for inclusion in the ranking, each scientist was required to meet a minimum D-index threshold of 40. Additionally, the majority of their top-tier publications had to be classified within the field of Chemistry.
Beyond bibliometric performance, the evaluation also factored in notable awards and achievements in Chemistry to better reflect recognized contributions to the field. The D-index threshold varies in increments of 10, calibrated according to the estimated total number of scholars within each discipline, to consistently incorporate the top 1% of leading experts. Moreover, the proximity between a researcher’s overall H-index and their D-index must be within 30%, ensuring discipline-specific excellence aligns closely with their general scholarly impact.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot fully capture the depth and quality of scholarly output, the Research.com team undertook rigorous manual verification of each scientist’s profile. This process included cross-referencing publications across a broad spectrum of trustworthy sources to ensure accuracy and authenticity.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is regarded as a valuable secondary signal indicating their contribution and influence within the Chemistry research community.
The ranking positions are ultimately established based on each researcher’s validated D-index, as calculated from data aggregated primarily from OpenAlex and CrossRef—widely regarded as the most extensive and reliable bibliometric databases accessible to the scientific community.
