A central determinant for an institution’s position in the ranking is the cumulative D-index (Discipline H-index) of all affiliated scholars whose primary field of publication is Materials Science. The D-index is a discipline-specific metric comprising only publications and citations relevant to Materials Science, ensuring precise representation of subject matter proficiency within each institution.
Scope of Research and Analytical Framework
The ranking process entailed a comprehensive analysis of 279,971 scientist profiles aggregated from various bibliometric sources. Out of these, 37,821 scientists specializing in Materials Science were specifically evaluated. To qualify, each scientist was required to have a minimum D-index threshold of 40, with the majority of their top-tier publications belonging to the Materials Science domain. Beyond bibliometric indicators, a scholar’s noteworthy awards and achievements in the field contributed to the assessment.
For the identification of top researchers, the D-index threshold is dynamically set, increasing in increments of 10, proportional to the estimated total number of scholars per discipline. This calibration allows the inclusion of the top 1% of leading scholars in each field. Moreover, the proximity between a scientist's general H-index and their D-index must not exceed 30%, ensuring that the scholar's impact is rooted predominantly in Materials Science. The evaluation thus combines both quantitative and qualitative facets, ensuring the inclusion of eminent, specialized researchers.
Verification Practices and Data Integrity
Recognizing that raw bibliometric data in isolation does not capture the full spectrum of a scholar’s impact, the Research.com team implemented rigorous verification protocols. Every scientist profile underwent manual verification, and data was cross-checked against an array of recognized and trustworthy publication sources. While the publication count in prominent journals and conference proceedings is not a criterion for ranking position, it remains an important secondary marker of scholarly contribution.
Ranking assignments rely on each researcher’s H-index—collected specifically for Materials Science—from OpenAlex and CrossRef, the most widely recognized and authoritative bibliometric databases accessible to the research community. In striving for transparency and rigor, we encourage all stakeholders to review the detailed assessment procedures outlined on our methodology page.
