Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Italy Ranking is primarily based on comprehensive bibliometric data collected from OpenAlex and CrossRef, supplemented by multiple other reputable data sources. These platforms are recognized for their extensive and high-quality scientific publication records and citation data. The bibliometric data used to devise the citation-based metrics for this ranking were meticulously gathered on January 12, 2026, ensuring up-to-date and accurate information.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that exclusively accounts for papers and citation metrics within the specific discipline of Materials Science. This metric allows for a targeted assessment of impact and productivity in the examined field.
Scope and Selection Criteria
The ranking’s scope encompasses a thorough evaluation of 279,971 scientist profiles aggregated from diverse bibliometric data sources covering all scientific disciplines. Within this comprehensive pool, 299 scientists identified explicitly with Materials Science were examined in detail. To qualify for inclusion in the ranking, a scientist’s D-index had to meet or exceed a threshold of 40, while a majority of their tier publications had to be primarily in the domain of Materials Science. Additionally, distinguished awards and significant achievements in the field were factored into the qualification process.
The D-index threshold is dynamically set as increments of 10 according to the estimated total number of scholars in each discipline. This approach ensures the inclusion of the top 1% of leading scholars relative to their discipline. Another important consideration was that the proximity between a scientist’s general H-index and their D-index should not exceed 30%, reinforcing the alignment of their disciplinary focus with their overall research output.
Verification and Validation Practices
Researchers behind this ranking recognize that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly contributions. To address this, every scientist profile was manually verified and cross-correlated against publications listed in an extensive range of trusted and authoritative sources.
While not directly influencing the ranking position, the number of papers published in prominent journals and conference proceedings was also considered a valuable secondary signal of a scientist’s contribution to the Materials Science community. The ranking itself was established strictly based on the D-index computed from data gathered via OpenAlex and CrossRef, which remain the most prominent and reliable bibliometric databases currently available to the research community.
