Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Materials Science Scientists in Sweden Ranking is primarily based on bibliometric data sourced from OpenAlex and CrossRef, two of the most prominent and widely recognized databases within the research community. These platforms provide comprehensive metadata on scholarly publications, including citation information. In addition to these primary sources, multiple other bibliometric databases and resources were consulted to ensure a robust and accurate foundation for the ranking methodology. The citation-based metrics employed in this ranking reflect bibliometric data collected on January 12, 2026.
A scientist’s placement in this ranking is determined by their Discipline H-index, or D-index. Unlike a general H-index, the D-index exclusively accounts for publications and citation metrics within a specific research discipline, providing a more focused evaluation of impact in the field of Materials Science.
Scope of Research and Inclusion Criteria
Our analysis encompassed a total of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources and spanning all scientific disciplines. Within the scope of Materials Science specifically, 133 scientists were examined in detail. To qualify for inclusion in the ranking, a researcher must meet several stringent criteria:
- A minimum D-index of 40, reflecting a substantial level of impactful work within Materials Science.
- A majority of their tier publications must be clearly classified within the domain of Materials Science.
- Recognition in the form of awards and achievements relevant to Materials Science was also considered to supplement bibliometric indicators.
The D-index threshold is adaptively set in increments of 10 depending on the estimated total population of scholars in each discipline to maintain a rigorous but inclusive approach. This threshold ensures that the top 1% of leading experts in Materials Science are consistently incorporated. Additionally, the methodology requires that the proximity between a scientist’s general H-index and their D-index remain within 30%, ensuring a strong disciplinary focus.
Verification and Methodological Rigor
Recognizing the limitations inherent in relying solely on raw bibliometric data, the Research.com team implemented thorough manual verification processes. Each scientist profile was carefully checked and cross-referenced against trustworthy publication records and multiple reliable sources to confirm accuracy and authenticity. While awards and citation metrics determine the ranking position, the number of papers published in highly regarded journals and conference proceedings serves as an important secondary indicator of the scholar’s contributions within Materials Science.
The final position of a researcher in the ranking is calculated based on their D-index, derived from data collected primarily through OpenAlex and CrossRef. These databases are renowned for their comprehensive coverage and reliability, which lend significant validity to the assessment performed.
