Which countries lead Electrochemistry research?

On research quality in 2022-now, China, the United States and Germany rank highest in Electrochemistry. By volume, China and India publish the most (5.4k and 1.5k works in 2022-now).

Who are the leading researchers in Electrochemistry?

Counting only their work in Electrochemistry, Allen J. Bard, Marc T. M. Koper and Michaël Grätzel have the most papers in the world top 10% for their subfield and year beyond the 10% expected.

  10. 10 Itamar Willner Israel · #9,822 worldwide overall 22.8 of 62 papers here in the top 10%

Ranked on their work in Electrochemistry alone: how many more of their papers here reached the world top 10% for their subfield and year than the 10% expected, among 369,952 ranked researchers with a paper here. Each paper counts once, so many strong papers outrank one famous one, and a long record of ordinary papers does not climb. Identities come from OpenAlex author disambiguation, which occasionally merges or splits people.

Where is the best place to study Electrochemistry?

Among universities, judged by research, Nanjing University, Hunan University and University of Chinese Academy of Sciences score highest, combining standing in the field's ranking, citation excellence, specialisation, size, growth and international reach. Research strength is one signal when choosing where to study; it does not measure teaching.

Universities only. The score blends standing (50%), citation excellence (20%), size (15%), specialisation (5%), growth (5%), international reach (5%), 2022-now; growth compares 2018-21 with 2022-25 and counts up to +20%, since a jump from a small base is mostly noise. Standing is the score in this field's institution ranking, three quarters over all time and a quarter 2022-now; excellence averages the two windows too. Four years alone undercount fields such as AI, where many conference and arXiv papers from 2022 on carry no affiliation in the data.
