Currently available methods of industrial nanodiamond synthesis

The main theoretical aspects of detonation decomposition of powerful mixed explosives with a negative oxygen balance accompanied by the formation of nanodiamonds (ultrafine-dispersed diamonds, UDDs) are described. The basic UDD synthesis parameters are considered, and the expediency of using trotyl-hexogen alloys is shown. The conditions of diamond phase conservation in the detonation products are specified. Various versions of industrial detonation synthesis of UDDs are considered. The most efficient technology of chemical cleaning of UDDs (with nitric acid at high temperatures and pressures) for producing UDDs with the highest purity is described.

     

Industrial Synthesis of Ultradisperse Detonation Diamonds and Some Fields of Their Use

The cluster nature of detonation-synthesized ultradisperse diamonds (UDD) is considered. The industrial cycle employed for obtaining ultradisperse diamonds is described, with different variations of this process and the basic principles of design of the necessary equipment noted. Priority product areas and advantages of use of ultradisperse diamonds in metal-diamond electrochemical coatings and polymer-diamond composites are discussed in detail.

Spin-Orbit Coupling in Deformed Harmonic Traps

We consider a two-dimensional system of harmonically trapped particles with pseudo-spin- \({\frac{1}{2}}\) degree of freedom. This degree of freedom is coupled to the particle’s momentum via the so-called Rashba spin-orbit interaction. We present our numerical results for a single-particle and few-particle systems, assuming the repulsive interparticle interaction to be of zero range.
