“…Therefore, the reduction processes are stipulated by the electron transport from carbon shell of mesoparticles in direction to Al+3 and Ni+2 of atoms in correspondent oxides. Exceptional properties of modified Metal Carbon nanostructures with magnetic characteristics lead to the property's improvement of nanostructured polymeric coatings [6][7][8]. For example, the introduction of 0,008% Cu C MC into the melamine-formaldehyde resins stimulates the polarization growth in two times (on the AFM data).…”

Mechanism of mesoparticles modification reactions are considered with the application of such notions as charges quantization, phase coherence, interference and annihilation. On the base of theoretical Mesoscopics ideas the formation of covalent bonds because of the interference of negative charges quants in modification reactions is discussed. The hypothesis about possibility of annihilation at the interaction of positive and negative charges quants in redox processes is presented. The magnetic metal carbon mesoscopic composites synthesis (for example, initial metal carbon Mesocomposites) is realized by mechanochemical method at the grinding of metal oxides microscopic particles with polyvinyl alcohol macromolecules. Then in the result the Copper or Nickel Carbon mesocomposites which have the following atomic magnetic moments: for Copper -1,3 μB, for Nickel -1,8 μB are obtained. The investigations are carried out on the analysis examples of processes of Copper and Nickel Carbon mesoparticles modification by the compounds containing p, d elements. In the middle of its such substances as polyethylene polyamine, ammonium iodide, ammonium polyphosphate (APP), silica (SiO 2 ), aluminum oxide, iron oxide, nickel oxide and copper oxide are used. It's noted that the red ox processes are accompanied by the metal atomic magnetic moments growth, that is explained by the electron shift on high energetic levels because of the annihilation phenomenon. The hypothesis concerning to the passing of two phenomena (annihilation and interference) at redox processes is proposed.

The new scientific trend, Chemical Mesoscopics, is based on the ideas of the Mesoscopics (Mesoscopic Physics) and also on the Mesoscopic Chemistry. This trend is considered on the instances on the reductionoxidation reactions peculiarities with nanostructures and mesoparticles participation. In this case such notions as the interference (the chemical bond formation), and the annihilation which stimulates the electron shift and leads to the chemical bond's formation, and also atom magnetic moment growth, are discussed. In this paper the explanation of the examples of the mesoscopic particles characteristics changes because of the Red Ox processes are given.

“…In this case Aluminum is reduced completely with simultaneous growth of Copper atomic magnetic moment from 1,3 to 4,8 Bohr magnetons. These changes are corresponded with the increasing of spin number on the Carbon shell from 10 17 spin/g to 10 19 spin/g [10]. Thus, it's possible to change the magnetic properties of mesoparticles and the number of unpaired electrons using the Red Ox reactions of metal carbon mesocomposites with different oxidizers.…”

“…In the case, when ammonium polyphosphate is replaced by aerosol (or silicon), the reduction of silicon from silicon oxide takes place by 50% independent of the used amount of the reagents (Figure 5); this can be explained by the decrease The early created method [10,11] on the base of the x-ray photoelectron spectra is used for the Copper Carbon mesocomposite modification mechanism investigation. The inner levels spectra for C1s, O1s, Si2p, P2p, S2p Cu3s are studied to investigate the mechanism of chemical bonds formation between metal or carbon atoms and silicon or phosphorus atoms.…”

In present mini review the definition of new scientific trend "chemical mesoscopics", which is based on the ideas of the mesoscopic physics (mesoscopics) and also more latest mesoscopic chemistry, is given. This new scientific trend includes quantum notions on mesoparticle reactivity in chemical reactions. In these cases the negative charges quants interactions (interference) are considered as well as the interactions of negative and positive charges (annihilation). The schemes of the chemical bonds formation at the reactions flowing into mesoscopic reactors are presented. The especial attention is devoted to the interactions of metal (Copper, Nickel) carbon mesoparticles with such oxidizers as Ammonium Polyphosphate and Aluminum Oxide. In these reactions it is observed the reduction of Phosphorus and Aluminum, the growth of mesocomposite metal atomic magnetic moment and the simultaneous increasing of spin quantity on the mesocomposite carbon shell. The introduction of "annihilation" notion explains the increasing of magnetic characteristics. The modification of polymeric materials (on example of epoxy resins) by metal carbon mesocomposites is considered. For the mesoparticle (nanostructures) reactivity estimation the proposals are done. These proposals are concluded in the using of Fractal Theory ideas (Kolmogorov -Avrami equations) together with energetic analogs of reactivity theory.
