Abstract: A new carbon allotrope is disclosed comprising an inner ring of 6 carbon atoms, which are characterized by hybridized sp2 bonds, as commonly found in graphite structure. Adamene further contains an outer ring of 12 outer carbon atoms which surround and are disposed in the same plane as the inner 6 carbon ring. The 12 carbons existing in the outer ring are characterized by sp3 hybridization, as seen in a diamond structure. The carbon allotrope additionally contains a ring of 12 carbon atoms disposed above or below the plane of the inner 6 carbon ring. These additional 12 carbons are characterized by sp3 hybridized bonding, found in diamond, and more specifically in hexagonal diamond, also known as Lonsdaleite.

Abstract: The present invention provides a new and useful synthetic carbon allotrope which contains multiple clusters of carbon atoms dispersed throughout the carbon allotrope. These clusters contain carbon atoms which are bonded to four other carbon atoms by sp2 hybridized bonds. The allotrope further contains multiple surrounding carbon atoms, which are bonded to each other by sp3 hybridized bonds. One of the multiple clusters of carbon atoms is centrally located within the carbon allotrope.

Abstract: The present invention provides a series of new and useful synthetic carbon allotropes. The carbon allotropes contain at least two inner hexagonal rings of 6 carbon atoms, which are characterized by hybridized sp2 bonds, as commonly found in graphene structure. The inner hexagonal rings are located in a central position within the carbon allotropes and bonded to each other in various configurations. Surrounding the hexagonal rings are additional carbon atoms, characterized by sp3 hybridized bonding, found in diamond, and more specifically in hexagonal diamond, also known as Lonsdaleite. These surrounding Lonsdaleite structures are bonded to and surround the inner hexagonal rings and support them in a central position within the carbon allotropes.
