“…In recent years, the effect of ionizing radiation fluxes has gained momentum in manufacturing and modification of materials. A fundamental phenomenon of a multiple increase in the speed of multicomponent powder synthesis [11][12][13][14] and sintering of compacts [15][16][17][18][19] induced by radiation-thermal mode was discovered. Sintering of lithiumtitanium ferrites under specific conditions of a combined effect of high temperatures and intense electron fluxesis the most well studied process [20][21][22].…”

The paper investigates the features of phase and structural transformations in lithium-titanium ferrites with regard to the time and temperature of solid-state sintering in thermal and radiation-thermal modes. These properties are studied with using the temperature dependence of the initial permeability. It is shown that electron beam exposure during solid-state sintering sharply accelerates the dissolution of impurity inclusions in ferrites. Also phase homogeneity of lithium-titanium ferrites products increase. The obtained results can be used for increasing of thephase homogeneity in ferrite production.

“…The effect of radiation intensification of the compaction process was established by comparing the sintering of lithium-titanium ferrites under the same conditions (temperature, time and sintering atmosphere, heating and cooling rates) but in different regimes (thermal and under conditions of combined exposure to high temperatures and penetrating radiation) [18][19]. It is shown that an increase in the compaction rate is due to the radiation-stimulated delay in the annealing of defects, which leads to the release of a compact material.…”

The effect of intensification of the compaction rate of ferrite compacts under irradiation conditions with a high-power electron beam both in the heating regime and in the isothermal stage of sintering was established. The compaction mechanisms of the compacts are different at each of these stages. The intensification of compaction at the non-isothermal stage in radiation-thermal conditions is due to processes involving the liquid phase. The role of bismuth oxide in the compaction of the material at the isothermal stage of sintering is unessential, but its influence is significant in recrystallization processes. Under of Ivensen’s phenomenology, compaction curves are explained by the deceleration of annealing of structural defects responsible for the fluidity of the material. Dislocations are the most probable type of defects, satisfying the detected regularities.

“…MG (Fig. 1) is now widely used: streptavidin-biotin method of immunophenotyping of human blood and bone marrow cells, coloring of vermiculite fraction in agriculture and floriculture, creation of electrochemical sensors and biosensors for the determination of organic compounds, staining of materials in the textile industry and so on [10][11][12][13][14][15]. Due to the fact that MG falls at a relatively high concentration in sewage and natural water, it is necessary to develop technologies for its utilization.…”

Degradation of toxicants in photocatalytic reactor is studied. To an array of data on the photochemical properties of Methylene Green (MG) when exposed to UV radiation in photoreactors was obtained. Based on the analysis of the results obtained, conclusions can be drawn about the relationship between the structure of pollutants, their initial concentration, oxidizer concentration, etc., with the efficiency of utilization, and schemes for photochemical processes was constructed. The role of polypropylene microfiber materials (PMM) in the degradation of MG under UV irradiation was studied.
