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 ...

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. The discovery of a stable single-electron covalent bond between two carbon atoms ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

A research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...

Hokkaido University researchers have synthesized an organic compound with a longer bond between carbon atoms than ever before—exceeding the assumed limit for carbon-carbon single bond (C-C) lengths.

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, ...

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus Pauling ...
