Data Sources and Citation Metrics
The 5th edition of the Research.com Best Chemistry Scientists in Netherlands Ranking is primarily derived from bibliometric data collected on 2026-01-12, utilizing authoritative sources such as OpenAlex and CrossRef, alongside multiple other complementary data repositories. These sources provide a comprehensive and up-to-date foundation for citation-based metrics that underpin the ranking. The position of each scientist within the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers the scientist's publications and citation impact within the specified discipline of Chemistry.
Scope and Selection Criteria
Our evaluation encompassed 279,971 scientist profiles identified from extensive bibliometric databases across all research disciplines. Specifically, this edition focused on 295 scientists within the field of Chemistry. To qualify for inclusion, a scientist’s D-index in Chemistry was required to be at least 40. Additionally, the majority of their tier publications had to be rooted within Chemistry to ensure disciplinary relevance. Consideration was also given to notable awards and achievements in Chemistry, acknowledging the broader contributions of researchers within the field.
The D-index threshold for selecting top researchers is calibrated incrementally by 10 points, depending on the estimated total number of scholars in each discipline. This adaptive threshold reliably guarantees that approximately the top 1% of leading scholars in a field are included. Moreover, only profiles where the proximity between a scientist’s general H-index and their D-index was 30% or less were considered, ensuring the D-index reflects consistent disciplinary impact rather than general citation volume.
Verification and Methodological Rigor
Recognizing that raw bibliometric data can never serve as an absolute measure of scholarly output, the Research.com team undertook comprehensive manual verification of all scientist profiles. This process involved cross-correlating publication records against a wide spectrum of reputable sources to affirm accuracy and legitimacy. While not a direct factor affecting ranking positions, the number of papers published in prominent journals and well-regarded conference proceedings was acknowledged as a valuable secondary indicator of a scientist’s substantive contributions within Chemistry.
The core ranking metric—the D-index—was established strictly from citation information aggregated via OpenAlex and CrossRef, two of the most prominent and reliable bibliometric databases accessible to the research community.
