A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that accounts exclusively for publications and related citation metrics within the examined discipline—Materials Science in this case. This discipline-specific approach allows for a more accurate and meaningful comparison of scholarly impact tailored to the unique characteristics of the field.
Scope of Research and Criteria for Inclusion
The ranking was devised from an examination of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources and disciplines. Among these, only 5 scientists specializing in Materials Science met the rigorous criteria required for inclusion.
To qualify for the ranking, each scientist was required to have a minimum D-index of 40, with the majority of their tier publications firmly situated within the Materials Science discipline. Additionally, distinctions such as awards and professional achievements in Materials Science were considered as supporting factors, enhancing the credibility of each candidate's contributions.
The threshold for the D-index is systematically adjusted in increments of 10 in accordance with the estimated total number of scholars in each discipline. This methodology guarantees that the ranking consistently reflects the top 1% of leading experts. Furthermore, a scientist’s general H-index and D-index were required to have a proximity of no more than 30% to ensure alignment between overall scholarly impact and disciplinary specialization.
Verification Practices and Methodological Transparency
The Research.com team is cognizant of the inherent limitations of raw bibliometric data in fully capturing the nuanced contributions of scholars. Therefore, all scientist profiles included in the ranking underwent thorough manual verification. These profiles were cross-correlated with publications indexed in a wide array of trustworthy sources to validate accuracy and comprehensiveness.
While the quantity of papers published in prominent journals and conference proceedings is not directly factored into a researcher’s rank, it is regarded as a valuable secondary indicator of a scientist’s meaningful contribution to the field.
The final position of each researcher in the ranking is established using their D-index as computed from data aggregated primarily from OpenAlex and CrossRef, ensuring reliance on the most robust and transparent bibliometric resources available.
