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 ...

PFAS are, in many ways, remarkable molecules. Even a thin layer can repel water, oil, and dirt. They are also highly resistant to heat and UV light, which makes them ideal for coating breathable ...

Katherine Bourzac is a freelance journalist in San Francisco, California. For a little more than a century, chemists have known that strong atomic links called covalent bonds are formed when atoms ...

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 ...

Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, have earned the nickname of forever chemicals from their extraordinary ability to stick around in the environment long after they’ve been used.

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 ...

Fluorinated graphene materials have emerged as a versatile class of two-dimensional nanomaterials in which covalent or semi-ionic carbon–fluorine bonds introduce a tunable bandgap, enhanced thermal ...
