Researchers use atomic force microscopy to image the chemical structure of the small molecule ... to distinguish a carbon atom from an oxygen or a nitrogen or a sulfur atom, for example.

Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared pairs of electrons.

Traditional atomic clocks are enormous ... "Fullerene" refers to its specific structure, resembling a "cage" of carbon atoms with a nitrogen atom enclosed inside. This name is inspired by ...

What are Nitrogen-Vacancy (NV) Centers? Nitrogen-vacancy (NV) centers are atomic-scale defects in the lattice structure of diamond. They consist of a substitutional nitrogen atom adjacent to a vacant ...

Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green ...
