AN attempt 1 to resolve misunderstandings regarding ionic-covalent bonding in solids has been criticized in a recent article by Mooser and Pearson 2. It should be pointed out, however, that their ...

One class of drugs that has shown promise in treating diseases ranging from lung cancer to COVID-19 are targeted covalent inhibitors (TCIs). These small molecule drugs form covalent bonds with their ...

Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

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 ...

"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 ...
