Chemists at the National University of Singapore (NUS) have developed a methodology to enable coupling reactions for the ...

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 bond? A hydrogen bond is an electrostatic ...

A research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...

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

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. The discovery of a stable single-electron covalent bond between two carbon atoms ...

Assessing hyperfine shifts in paramagnetic NMR spectra provides new details on the covalent character of halogen bonded ...

Human cancer cells cultures in the lab of David Heppner. Heppner's team recently found that faster binding for targeted covalent inhibitor drugs was linked to greater potency, but only to a certain ...
