The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Criegee intermediates are transient carbonyl oxide species generated during the ozonolysis of alkenes, and they play a pivotal role in atmospheric oxidation processes. Their formation initiates a ...

Reactions that completely break carbon-carbon double bonds have particular transformative power in synthesis. Ozonolysis, which splits one alkene into two carbonyl compounds using trioxygen, is widely ...
