A physical phenomenon called quantum tunnelling is rare in chemical reactions, making it difficult to study theoretically and experimentally. The measurement of the tunnelling rate in a hydrogen ...

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27.

Thermonuclear reaction rates power the models that explain how stars live, explode and create the elements. A new study ...

Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its ...
