Abstract
Revised structure of the primary particle of single-nano detonation diamond (SNBD) are constructed by merging our own experimental observations with the results from self-consistent charges density functional tight binding (SCC-DFTB) calculations by Barnard. Internal geometrical structure is characterized by triply-decked core-shell structure with graphene layers on the surface, electronic structure by strong electrostatic potential fields of both signs over the facets, and surface structure by intermixed graphene/diamond patches. Surprisingly high stability of colloidal solution of SNBD is interpreted in terms of strong hydration over the charged facets. Rapid aggregation of primary particles by the changes in pH and the addition of electrolytes are mentioned by invoking ligand exchange reactions that take place on the charged facets involving hydrated water molecules and protons or metallic ions. In this way a considerably improved picture on the characteristic behaviors of this novel nanocarbon emerged. The most remarkable feature of SNBD is that diamond polarizes in nano.
