NANO and DIAMOND is the winning combination.
Diamond is the most wonderful mineral
in the world widely used in jewelry due to its luminescence and dispersity.
Diamond has the highest hardness and thermal conductivity of any bulk material.
These features determine the major industrial application of diamond in cutting
and polishing tools. Outstanding properties of diamond originate from the
strong covalent bonding between carbon atoms collected in cubic lattice. Each atom
inside diamond structure is located in the center of the tetrahedron whose
vertices are the four neighboring atoms and covalently bonded with them by sp3
hybridization. This strong and dense packing of carbon atoms define unique
properties of diamond:
