Since the majority of entities in the sector of great chemical synthesis was owned by State Treasury at that time, the reorganisation and privatisation strategy was developed for the sector of great chemical synthesis. [2] It identified, e.g. weak connections between the particular production plants and the necessity to reorganise them.

the ultrafine size of the mea-nps may be attributed to two reasons: (i) the high-temperature duration of the rapid synthesis is only 0.5 s, thus limiting the particle diffusion and coalesce to ensure a uniform distribution; (ii) the use of defective carbon substrates allows the defects to stabilize the particles during synthesis and prevent .
