Natural diamond, seen here, has a cubic packing structure. But a much rarer form of diamond has hexagonal packing and has now ...

Carbon nanomaterials are a class of nanoscale materials composed primarily of carbon atoms. These materials are different allotropes of carbon, meaning they have distinct physical structures but are ...

Carbon allotropes, ranging from highly ordered structures such as graphene and nanotubes to more molecular forms such as fullerenes and cubane derivatives, exhibit a fascinating interplay between ...
