Data Sources and Bibliometric Information
The 5th edition of the Research.com Best Chemistry Scientists in Macedonia Ranking was developed primarily using comprehensive bibliometric data harvested from OpenAlex and CrossRef, supplemented by multiple other reputable data sources. These sources collectively provide an extensive and up-to-date dataset of scholarly publications and citations across diverse disciplines. The citation-based metrics employed in the ranking were extracted and analyzed based on data collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric which specifically considers only their publications and citation impact within the discipline of Chemistry, ensuring a focused and discipline-relevant assessment.
Scope of Research and Qualification Criteria
A total of 279,971 scientist profiles were initially identified and examined across a broad spectrum of disciplines using a variety of bibliometric data sources. Within this extensive dataset, 1,000 scientists specifically engaged in Chemistry were isolated for closer examination.
To qualify for inclusion in the Chemistry ranking, researchers were required to meet a minimum D-index threshold of 40. Additionally, a majority of their tier publications needed to be firmly rooted in Chemistry. The evaluation also factored in awards and notable achievements within the field, further contextualizing the impact and recognition these scientists have attained.
The D-index threshold is structured as an increment of 10, calibrated to the total estimated number of scientists in each discipline. This approach ensures that the top 1% of leading scholars within each area are comprehensively represented. Importantly, qualified scientists demonstrate a proximity of no more than 30% between their overall H-index (general research impact) and their specialized D-index, signifying consistent and significant contributions within the Chemistry discipline.
Verification and Validation Process
Recognizing that raw bibliometric data alone cannot entirely capture the multifaceted contributions of scholars, Research.com implemented a rigorous manual verification process. Each scientist’s profile was carefully cross-checked against publications listed in an array of trustworthy sources to authenticate accuracy and relevance.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it is acknowledged as a valuable secondary indicator of a scientist’s scholarly contributions within their field.
The ranking positions are firmly grounded on each researcher's validated D-index, computed through data gathered from OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases available to the scientific community.
