"SOMETIMES IT SEEMS to me that a bond between two atoms has become so real, so tangible, so friendly, that I can almost see it. Then I awake with a little shock, for a chemical bond is not a real ...

Congratulations on “Chemical Connections,” which summarizes the peculiar history of our understanding of the nature of the chemical bond (C&EN, Sept. 9, page 28). I agree with most of the article, ...

Researchers have developed a first-of-its-kind model for providing a comprehensive description of the way in which molecular bonds form and rupture. This model enables researchers to predict the ...

Could helium molecules form in very high magnetic fields? In the extreme magnetic fields of white dwarves and neutron stars, a third type of chemical bonding can occur. That is the finding of ...

One of the key challenges in chemistry is to break and form bonds selectively in complex organic molecules that possess a range of different functional groups. To do this at the single-molecule level ...

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 ...

Light-induced breakage of chemical bonds can lead to damage in the body and environment, but techniques for studying this photochemical reaction have been limited to before and after snapshots. With ...

Imagine what it would be like to watch how the individual atoms of molecules rearrange during a chemical reaction to form a new substance, or to see the compounds of DNA move, rearrange and replicate.

Making a connection: An artist's impression of a Rydberg atom bonded to an ion. (Courtesy: Danyel Cavazos) A novel type of molecule that is longer than some kinds of bacteria has been detected by ...

If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At least not without a liberal amount of adhesive, water or some other ...
