System and method for the fabrication of nanodiamond particles

A method for fabricating nanodiamond particles, which method comprises:

• a) forming a composite of a plurality of diamond monolayers interspersed with a plurality of non-monolayers of dihydrobenzvalene (DHB), one over the other, by reacting paramagnetic kinetically energized carbyne radicals with a supported layer of DHB, at solidus temperature, thus sealing off any subtended, unreacted DHB from further reaction with the paramagnetic kinetically energized carbyne radicals, said paramagnetic kinetically energized carbyne radicals being generated as paramagnetic carbyne radicals from a radiolysis cavity and transiting therefrom through a magnetic accelerator to become kinetically energized and transiting through a mass flow conduit to the supported layer of DHB at solidus temperature, and
• b) draining liquified DHB from the composite and impacting the remaining diamond monolayers wetted with DHB with a guillotine having an anvil with a nanomachined strike face and which anvil is driven with sufficient force to fracture the diamond monolayers to thereby produce nanodiamond particles having a shape in an X-Y plane matching a profile of the nanomachined strike face and a Z-axis dimension (thickness) which is that of a diamond monolayer.
