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 ...

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 ...

AN EXOTIC type of nitrogen could form the next generation of safe, energy-dense rocket fuels or explosives, provided someone can figure out how to make it. In its most common state, nitrogen is an ...
