Counting only their work in Analytical Chemistry, Janusz B. Pawliszyn, ‪Damià Barceló and Da‐Wen Sun have the most papers in the world top 10% for their subfield and year beyond the 10% expected.

Question 4

Where is Analytical Chemistry research done?

Accepted Answer

The largest centres of Analytical Chemistry research in 2022-now are Beijing (China), Tehran (Iran), Nanjing (China) and Hangzhou (China). Among places with at least 20 works in it, it is an unusually large share of all research in Çankaya, Jinrongjie and Daqing.

Question 5

Where is the best place to study Analytical Chemistry?

Accepted Answer

Among universities, judged by research, Zhejiang University, University of Chinese Academy of Sciences and China Agricultural University 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.
