Sources of Data and Bibliometric Collection
The 5th edition of the Research.com Best Materials Science Scientists in Morocco Ranking is primarily based on comprehensive bibliometric data sourced from OpenAlex and CrossRef, alongside multiple other reputable data sources. These platforms represent some of the most prominent and reliable bibliometric databases available to the international research community. The citation-based metrics used to devise this ranking were collected on January 12, 2026, ensuring that the analysis reflects the most recent and relevant scientific contributions. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a specialized metric that considers only the publications and citation data pertinent to the Materials Science discipline under examination.
Scope of Research and Qualification Criteria
The ranking encompasses an extensive analysis of 279,971 scientist profiles identified from a variety of bibliometric data sources, covering all scientific disciplines. Within this broad examination, 4,000 scientists specializing specifically in Materials Science were evaluated. To qualify for inclusion in the ranking, each candidate was required to have a minimum D-index of 40. Furthermore, a majority of a qualifying scientist's top-tier publications needed to be within the Materials Science domain. Additional factors such as awards and notable achievements in the field of Materials Science were also considered to enrich the assessment.
The D-index threshold — set in increments of 10 — adapts according to the estimated total number of scholars within each discipline. This approach ensures the ranking incorporates the top 1% of leading scientists. An important quality control measure includes maintaining a proximity of 30% or less between a researcher’s overall general H-index and their D-index, reinforcing the discipline-specific impact of a scientist’s work.
Verification and Validation Practices
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or scientific contribution. To uphold the highest standards of accuracy and credibility, all scientist profiles included in the ranking were manually verified and rigorously cross-correlated against publications listed in a wide array of trustworthy sources. While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher's position in the ranking, it is considered a valuable secondary indicator of their contribution to the field.
The final ranking position is established based on each researcher's D-index, derived from information aggregated from OpenAlex and CrossRef, which remain the most comprehensive and widely respected databases for citation metrics and scholarly record-keeping.
