A structurally stable crystalline carbon allotrope is predicted by means of the first-principles calculations. This allotrope can be derived by substituting each atom in diamond with a carbon ...

(Nanowerk Spotlight) Carbon is the fourth-most-abundant element in the universe and, depending on the arrangements of carbon atoms, takes on a wide variety of forms, called allotropes. Carbon ...

Diffraction data taken from nanocrystalline n-diamond and i-carbon forms is fit to a so-called glitter model, in which the geometry of the C lattice has been optimized by density functional theory ...

Ozone is an allotrope of oxygen, for example, while graphite and diamond are both allotropes of carbon. A section of the periodic table. Nitrogen (red) was thought to not have allotropes with similar ...

Researchers have used a diamond anvil to smash nitrogen into a previously unseen form they call black nitrogen. The nature of nitrogen led researchers to believe this flat, crystalline form wasn't ...
