This is the fourth consecutive year in which leading institutions of China, France and Germany have topped the field in high-quality chemistry research output.

The biggest movers in this category for 2018 include Tsinghua University in China, which jumped from 17th place in 2015 to 6th place in 2018, and Nanjing University, which climbed six spots from last year to secure the 4th spot for 2018. Kyoto University in Japan dropped out of the top 10 after ranking 4th last year. See the 2019 Annual Tables Top 100 institutions for chemistry in 2018.

1.Chinese Academy of Sciences

Fractional count*: 881.87, (6.8%)†, Article count‡: 2,206

The Chinese Academy of Sciences (CAS) has retained the world’s top slot in chemistry for the past four years in the Nature Index, and in 2018 had almost four times the fractional count of the number 2 seed, the French National Centre for Scientific Research.

A major point of difference for CAS is its enormous size, encompassing 105 institutes across China, which support more than 60,000 research staff. Of note among its many chemistry-focused institutes are the highly productive Institute of Chemistry(IOC), based in Beijing, and the Dalian Institute of Chemical Physics, which specializes in such areas as catalytic chemistry, chromatography and pharmaceutical chemistry.

In 2018, in a high-impact paper published in the Journal of the American Chemical Societyby IOC scientists described a new type of solar cell that can achieve unprecedented power conversion efficiency rates.

CAS president, Bai Chunli, is a physical chemist and nanoscientist, known for his pioneering work in scanning tunnelling microscopy and nanotechnology.
