The hydrogen bond forms between the hydrogen attached to the red oxygen and the nitrogen atom. A few more images, of the molecules with different hydrogen bond connections: Zhang, et. al, Science ...

Making compounds, such as nylon, that need the carbon-nitrogen bond currently requires making ammonia along the way, Chirik says. The new method may offer an alternative.

A hydrogen bond, in this picture, ... nitrogen or fluorine that likes to suck in electrons and turn into a negatively charged ion – elsewhere in the same molecule or in a nearby molecule. ...

The new bonds had a strength of 45.8 kilocalories per mol (a unit of chemical bonding energy), greater than some covalent bonds. Nitrogen molecules, for example, are made of two nitrogen atoms ...

Bonding writ large WITHOUT them, life as we know it could not exist, yet the exact definition of the hydrogen bond – credited with keeping water liquid and giving DNA its signature helical shape ...

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.

By breaking the strong bond between nitrogen and hydrogen, i.e. activation, the ammonia molecule may be transferred at least theoretically to other molecules, such as unsaturated hydrocarbons.

On Protein Folding One paragraph in this story1 contains confusing terminology. The use of the term nitrogen-hydrogen bond for amide-hydrogen is a simplification too far. "Hydrogen bonds" in proteins ...

To highlight the bonds associated with nitrogen, a H-terminated surface is used as the reference in Fig. 1a, and an oxidized surface is used to examine the Si–H bonds in Fig. 1b.

Optical light strikes the molecule, and it loses a proton bound to hydrogen. An X-ray probe allows scientists to follow selective bond breaking between nitrogen and its carbon and hydrogen neighbors.

Living organisms, including humans, owe their complexity primarily to molecules consisting mainly of carbon, hydrogen, nitrogen, and oxygen. These building blocks form the basis of countless ...
