And now, after years of work, they’ve finally explored an idea originally proposed in 1931: a chemical bond formed using just a single electron. This, of course, ...

Photoactivated ketones show strong potential as hydrogen atom transfer photocatalysts, enabling the activation of carboxylic ...

The researchers deployed a special quantum effect called the two-photon spin-exchange Auger process to produce hot electrons far more efficiently than before. This process allows two low-energy ...

For the first time, researchers have created a solid compound containing a beryllium-beryllium bond (Science 2023, DOI: 10.1126/science.adh4419). The compound is diberyllocene, in which each ...

Researchers had previously coaxed two atoms to bond (SN: 4/12/18). But directly observing how chemical bonds change in number “was not done before,” says physicist Ute Kaiser of Ulm University ...

From Nature magazine. An elite chemical club has a new member, after a team in Germany found a way to link two boron atoms together with a stable triple bond. Boron joins carbon and nitrogen as ...

Higher; Chemical energy Bond enthalpies. Energy changes occur in chemical reactions as bonds are broken and new bonds formed. Enthalpy changes can be calculated from experimental data, and are ...

These gelatin chains have hydrogen atoms attached to their sides.These hydrogen branches can weakly bond with water. This isn't a true chemical bond: the water remains as good old H2O, but the ...
