A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...

Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

Hydrogen bonding, so significant in biology, is finally being exploited as a primary adsorption mechanism. BIA Separations shows how. Its salt-tolerant approach separates proteins by size.

A research team led by Prof. Pan Feng from the School of Advanced Materials, Peking University Shenzhen Graduate School has ...

A hydrogen bond 1 forms between an electronegative atom (the acceptor) and a hydrogen atom covalently bound to another electronegative atom (the donor). Hydrogen bonds are of key importance in ...

Hydrogen bonds are typically thought of as weak electrical attractions rather than true chemical bonds. Covalent bonds, on the other hand, ...

Hydrogen bonds are incredibly useful and they’re all over nature. Most famously, they’re responsible for holding the two strands of the double helix of DNA together.

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. This technique can be used ...

Hydrogen bonds bind water molecules to each other, giving the droplet its characteristic shape. But they're easily broken. Researchers recently discovered a form of hydrogen bond so strong it's ...
