The nitrogen-containing fragments are particularly important because both the basic character of the nitrogen lone pair and the hydrogen bond–donating capacity of the NH group can be modulated ...

Researchers have developed a new chemical tool that could help lower the cost of prescription medications. The tool, called AshPhos, is a ligand, or molecule, that makes it easier to create special ...

By selectively targeting a specific C–H bond, they open doors to synthetic ... to molecules consisting mainly of carbon, ...

Hydrogen is considered a clean energy source ... "Ligands such as AshPhos facilitate the formation of carbon-nitrogen bonds by stabilizing metal ions and guiding them in reactions, called Buchwald ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen ... two nitrogen atoms joined together. Nitrogen atoms can form three covalent bonds ...

These Ru nanoclusters react with ammonia molecules, catalyzing splitting ammonia into hydrogen and nitrogen—an essential step toward green hydrogen production. This research is published in ...

University of Missouri researchers and collaborators have developed a new chemical tool that could help lower the cost of ...
