The positioning of each scientist in the ranking is determined by their D-index (Discipline H-index). Unlike a general H-index, the D-index exclusively considers publications and citation metrics within the examined discipline, ensuring a more precise and relevant measure of scientific impact within Materials Science.
Scope of Research Considered
The ranking reviewed 279,971 scientist profiles identified from a broad array of bibliometric data sources across all scientific disciplines. From this extensive pool, 5 scientists specializing in Materials Science in Luxembourg were thoroughly evaluated.
To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 40, with the majority of their high-tier publications primarily focused on Materials Science. In addition to bibliometric indicators, a candidate’s awards and significant achievements within the field of Materials Science were also carefully considered.
The threshold for the D-index is adjusted in increments of 10 relative to the estimated total number of scholars within each discipline, while ensuring the inclusion of the top 1% of leading experts. To maintain consistency and disciplinary relevance, each scientist’s general H-index and D-index were also required to have a proximity difference of 30% or less.
Verification and Methodological Rigor
At Research.com, we fully acknowledge that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s output. Consequently, every scientist’s profile included in the ranking was subjected to meticulous manual verification and cross-correlation against publications found in a broad spectrum of reputable and trustworthy sources.
While the number of papers published in prestigious journals and conference proceedings is not a direct factor influencing the ranking position, it is considered a valuable secondary indication of a scientist’s contribution to the advancement of Materials Science research.
The final ranking positions are firmly anchored on the D-index derived from data curated primarily through OpenAlex and CrossRef, two of the most comprehensive and respected bibliometric databases accessible to the research community today.
