Abstract

Nanodiamond (ND) particles as small as 4 nm are separated from powdered ND prepared by a static high-pressure high-temperature (HPHT) method using ultracentrifugation. The size of the isolated ND is tunable, ranging from 4 to 25 nm, by the selection of appropriate duration and acceleration of the centrifugation. The availability of various sizes of ND particles enables full and precise investigation of their size effects.
