Millimetre-sized single crystals of covalent organic frameworks have been constructed by taking advantage of a reversible dimerization reaction of nitroso groups. Scientists and non-scientists alike ...

Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule contains ...

Selective reaction of one alcohol among many in complex molecules can be achieved by the use of a catalyst that forms a single covalent bond to a nearby functional group. Fast, selective and high ...

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 ...

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 ...
