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 ...

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 ...

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries ...

Chinese scientists proposed a novel imine-to-olefin transformation strategy to synthesize single-crystal sp² carbon-linked covalent organic frameworks (sp²c-COFs). COFs are crystalline, porous ...

The strength of the thiol–gold interactions provides the basis to fabricate robust self-assembled monolayers for diverse applications. Investigation on the stability of thiol–gold interactions has ...

In this interactive activity adapted from NOVA, explore the prevalence of ringed-carbon structures in the natural world, as well as the structural variations that give rise to their unique chemical ...

Using advanced microscopy techniques, researchers have recorded the breaking of a single chemical bond between a carbon atom and an iron atom on different molecules. The team used a high-resolution ...

The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state. Changes of state: ...
