Last month we heard about a brand new solid form of carbon, separate to the graphite and diamond forms that we already know so well. Called Q-Carbon because of the way that it is created (carbon is ...

Carbon, one of the most versatile elements known, occurs in a multitude of allotropes that exhibit a wide array of physical and chemical properties. The diversity of carbon’s bonding—ranging from sp² ...

There are many different carbon allotropes. Some are bulk materials, such as diamond or graphite, whereas others are nanostructures materials ­– such as carbon nanotubes (CNTs) and graphene. All ...

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 ...

Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite. Scientists have now discovered a new form of carbon, ...

Carbon atoms can be combined in different configurations with widely varying properties. Graphite and diamond are the most familiar, while more exotic allotropes include graphene, with versatile ...

Calculations have predicted the existence of a previously unconsidered form of carbon. The difference between diamond and graphite is surprisingly modest: the carbon atoms in diamond are bonded into a ...

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 ...

Ask most people what the hardest material on Earth is and they will probably answer “diamond”. Its name comes from the Greek word ἀδάμας (adámas) meaning “unbreakable” or “invincible” and is from ...

Diamond, one of the hardest known materials, could have a rival. A new form of carbon that is just as hard as the gemstone but as light as pencil graphite could theoretically be used for applications ...

Diamonds are forever, and so is their extreme hardness. But unlike diamond, a bizarre form of carbon can change its properties, going from squishy to hard and back again, if pressure on the material ...
