Besides the three basic forms of carbon, i.e. diamond, graphite/graphene and fullerene, a fourth carbon allotrope has been identified. We obtained this carbon allotrope in form of epitaxial films on diamond in a quantity sufficient to perform their comprehensive studies, and provided clear evidence for its unique crystal and electronic structure. Its band gap was found to be typical for...
Carbon nanomaterials have revolutionized the field of biomedicine, offering opportunities for their diverse applications. Their unique tunable physicochemical, optical, mechanical and electronic properties make them ideal candidates for a wide range of biomedical applications such as drug delivery, biosensing, and imaging. However, to harness their full potential and ensure their safe and...
We produce curved graphene hyperbolic pseudosphere surfaces in molecular dynamics (MD) simulation of a nano-scale extrusion process, in which C atoms are forced down a pseudo two-dimensional volume shaped like a hyperbolic pseudosphere. During the extrusion process the carbon atoms form pentagons, hexagons and heptagons and such a mixture is unrealistically less stable than pure graphite or...
