Chemists have been able for the first time to measure how new bonds influence molecules: they have reconstructed the 'energy landscape' of acetone molecules using measurement data from the Swiss Light ...

Chemical bonding enables scientists to take the 100-plus elements of the periodic table and combine them in myriad ways to form chemical compounds and materials. The success rate is pretty good, as ...

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

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 ...

Illustration of intracluster bond formation, cluster containing two biomolecules, being exposed to UV light (left), causes a chemical bond forming between the two molecules (center), resulting in a ...

The latest short science news items from C&EN. Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen ...

We all remember the basic principles taught in high school chemistry class: There are three types of chemical bonds. However, covalent, ionic and metallic have a little competition now. There’s a new ...
