Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Oman Ranking is primarily constructed using bibliometric data sourced from OpenAlex and CrossRef, two of the most prominent and widely recognized bibliometric databases accessible to the global research community. In addition to these, multiple other reputable data sources were also incorporated to ensure a comprehensive assessment. The citation-based metrics underpinning the ranking were collected on January 12, 2026, ensuring that the analysis reflects the most recent and relevant scientific outputs. A scientist’s position within the ranking is determined using their D-index (Discipline H-index), which exclusively considers publications and citation metrics related to the specific discipline under examination, in this case, Materials Science.
Scope of Research and Ranking Criteria
The ranking encompasses an extensive examination of 279,971 scientist profiles drawn from a diverse range of bibliometric data sources across all disciplines. Among these, 1,000 scientists specializing in Materials Science were specifically evaluated for inclusion. To qualify for the ranking, a researcher’s D-index had to be at least 40, with the majority of their tier publications firmly rooted in the Materials Science discipline. In addition to quantitative bibliometric thresholds, scientists’ awards and achievements within Materials Science were also integral factors in the selection process.
The D-index threshold for identifying top researchers is calibrated in increments of 10, tailored to the estimated total number of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading experts. Furthermore, to maintain a focused discipline-specific evaluation, it was required that the proximity between a scientist’s general H-index and their D-index did not exceed 30%, ensuring that the ranking reflects true expertise and impact within Materials Science.
Verification Procedures and Ranking Methodology
Recognizing that raw bibliometric data alone cannot comprehensively evaluate a scholar’s output, all scientist profiles included in the ranking underwent meticulous manual verification. This process involved cross-correlating individual publication records against a wide array of trustworthy sources to confirm the authenticity and relevance of their work within the field of Materials Science.
While not a direct factor in determining ranking positions, the volume of papers published in prestigious journals and conference proceedings was considered a valuable secondary indicator of a scientist’s contributions. The ranking positions themselves are established exclusively on each researcher’s D-index, derived from data collated via OpenAlex and CrossRef, representing the forefront of available bibliometric resources.
