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 ...

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 ...

Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. Diamond and graphite are two naturally occurring 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 ...

We can all only dream of owning rocks made of these. Simulations have revealed three stable forms of pure carbon that would sparkle more than diamond if synthesised. To explore whether forms of carbon ...

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 ...
