Research.com, a leading academic platform for researchers, has just released the 2025 Edition of Ranking of Best Scientists in the field of Chemistry.
The ranking is based on D-index (Discipline H-index) metric, which only includes papers and citation values for an examined discipline. The ranking includes only leading scientists with D-index of at least 40 for academic publications made in the area of Chemistry.

The world’ top chemist of 2025 Prof. M. Grätzel used cyclodextrin to improve the efficiency of his famous dye-sensitized solar cell, also known as “Grätzel cell”.
(H. Choi et al. (2009) An Efficient Dye-Sensitized Solar Cell with an Organic Sensitizer Encapsulated in a Cyclodextrin Cavity, Angewandte Chemie>)
We are especially happy to learn that Lajos Szente, a leading Hungarian scientist, former CEO of CycloLab and a corresponding member of the Hungarian Academy of Sciences, has been ranked 23 in Hungary and 14580 in the world.
