Empa researchers have experimentally recreated a fundamental theoretical model from quantum physics, originally proposed by ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

A new reagent has moved carbon-atom transfer out of the chemical flatlands, allowing chemists to place a single carbon atom so that it makes bonds to four different substituents. The reagent makes ...

The number of bonds a carbon atom forms with other elements in a compound determines its chemical structure and behavior. Normally, a carbon atom shares all four of its valence electrons to create ...
