Diamond and graphite are polymorphs of carbon, for example. Some molecules can crystallize in as many as a dozen or so different forms, Szalewicz said. “Investigations of crystal structures are an ...

Because graphite is a semimetal, it contains fewer charge carriers ... A single layer of graphene can be described as a simple repetition of carbon atoms arranged in a crystal structure known as a ...

The hardness of a crystal is measured on a scale ... than diamond. The planar structure of graphite allows electrons to move easily within the planes. This permits graphite to conduct electricity ...

The structure of graphite crystal is a repetitive pattern. This pattern gets disrupted at the surface of the crystal and leads to what's called 'surface states', which are like waves that slowly ...

The film discusses the significance of carbon, highlighting its presence in 90% of known compounds and its various forms, such as diamond and graphite. It explains the atomic structure of carbon ...

Carbon, for example, exists as diamond or graphite depending on the environmental conditions at the time of formation. Crystal structures that have been formed in ultra-high-pressure environments ...

The foam's unusual graphite crystal structure is the key to its conductivity. It has a skeletal structure full of air pockets, making it only 25 percent dense and lightweight. The network of ...

The structure, an interlocking form of graphite and diamond, has unique properties that could one day be used to develop superfast charging or new types of electronics, researchers say.
