Identifying novel carbon allotropes is an active research field targeting materials with specific characteristics such as mechanical properties approaching diamond's ultra-hardness by using modern materials research software as structure predicting USPEX based on evolutionary crystallography . Also, in view of the large number of claimed stoichiometries and structures worldwide, a database: SACADA (SACADA 3D) categorizes known carbon allotropes labeling them with different topologies (ex. "dia" for diamond) helping researchers in their endeavor and avoiding claims of structurally related systems as novel allotropes .
