EPR spectra
Comparing with detonation nanodiamonds, nanodiamonds produced by laser synthesis (RayND) demonstrate enhanced paramagnetism, increased amount of RPC and stronger anti-ferromagnetic exchange interaction between these RPC.
Thermo-gravimetric analysis
The change of mass in the process of burning. RayND (left) are more homogeneous both geometrically and chemically, than detonation nanodiamonds of high quality (right).
