For a little more than a century, chemists have believed that strong atomic links called covalent bonds are formed when atoms share one or more electron pairs. Now, researchers have made the first ...

A team of researchers affiliated with both the University of California–Berkeley and the Kavli Energy Nanoscience Institute at UC, has developed a new covalent organic framework (COF) using boron and ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...
