Main scientific achievements 

Problem I. Scientific basis of radiation safety, environmental problems associated with the spread of radioactive materials and substances in nature 

1.Despite the fact that more than 29 years have passed since the last use of pesticides, there are remnants of 4.4' DDT and its decomposition products, 4.4' DDE and 4.4' DDD in the liberated Jabrayil, Aghdam and Terter regions , on the soil surface. The highest concentration is observed in a soil sample taken from the territory of Agdam district (4.4 DDE - 143.748 µg/kg and 4.4 DDT - 7.553 µg/kg, respectively). During the occupation, it was found that as a result of illegal mining in the Zangilan region, the environment was polluted with heavy metals.

2. The concentration of radon in water was determined in the liberated from occupation in the village of Istisu, Kalbajar region. The concentration of radioactive radon in the thermal waters of a recently dug artesian well near the Lower Istisu site is below the permissible limit. The concentration of radioactive radon in the cold and thermal waters of the Bagyrsag village, in the western foothills of the Dalidag ridge, is 100 times higher than the permissible limit, and these waters are undrinkable. The magnitude of the radioactive background in this area is 15 times higher than the permissible norm.

3. Paramagnetic centers were studied in the leaves of some woody plants in the liberated territories. Based on studies of electron paramagnetic resonance (EPR) spectroscopy, it has become known that environmental pollution causes a magnetization effect in plants.

4. Treatment of gamma-irradiated (100-200 Gy) seeds of autumn wheat varieties "Tarter" and "Guneshli" with solutions of the zinc hypoxanthine-9-riboside complex with a concentration of 0.1; 0.01; 0.001% accelerated the biosynthesis of pigments in seedlings, resulting in an increase in productivity (ear length, number of grains and weight) by 14-15% in the Tartar variety and by 18-20% in the Guneshli variety.

5. Treatment of seeds with γ-rays in doses of 5-10 Gy before sowing allows growing samples with a higher yield, high fiber yield, long fiber and a larger mass of cotton in the cone.

Problem II. Physico-chemical processes occuring under the influence of ionizing rays in semiconductor, polymeric, dielectric nanosystems, directional control of their properties, increasing radiation resistance and preparation of receivers of ionizing radiation

1. A radiation-stimulated transition to the superionic phase was observed in the TlSe1-xSx solid solution. It is shown that the feature observed in the dependence of the hodogram of the impedance Z//(Z/) of the TlSe1-xSx solid solution in the low-frequency region is associated with the presence of both capacitive polarization near the electrode as a result of charge accumulation in the double electric layer region and polarization resistance. The result obtained models the linear diffusion impedance, known as the Warburg diffusion impedance, obtained by gamma irradiation.

2. The TlInS2<10%C> compound with a single-crystal structure was studied by impedance spectroscopy, it was found that the conductivity at a temperature above room temperature is mainly ionic in nature and depends on the irradiation dose. Thus, the proportion of ions in the electrical conductivity before irradiation is 63%, and after irradiation of 200-800 kGy - 79%. The values of activation energy with increasing dose received values equal to ∆Еа1 = 0.54 eV, ∆Еа2 = 0.32 eV, ∆Еа3 = 0.22 eV. The stimulating effect of radiation on ionic conductivity is due to the breaking of interatomic bonds and Tl+ ions, which play a key role in ionic conductivity.

3. The electrical, optical and photoelectric properties of GaS thin films 1-5 µm thick, obtained by thermal evaporation, are modified under the influence of gamma quanta, and it was found that in samples thermally treated below the critical dose, as a result of the reduction of bonds (Ga-S, Ga- Ga, S-S) increases resistance to radiation. It has been shown that these radiation-modified materials can be successfully used in solar panels as photoconverters.

4. In order to obtain absorbers of electromagnetic waves of microwave frequencies using modern methods of analysis (SAXS, XRD, FTIR, DCK, TGA), the effect of temperature and radiation on the structure and electrophysical parameters of PVDF/nano-Fe3O4, YSPE/nano-Fe3O4 and PVA composites was studied. nano-Fe3O4. It has been established that irradiation of composites in the dose range of 50-300 kGy changes the values of electrophysical parameters (ε, tgδ and ) very little, which indicates a relatively high resistance of composites to gamma irradiation. The nanofiller increases the thermal stability of the composite by ~30K compared to the matrix.

5. Comparative analysis of the temperature [logρ=f(1/T)] dependences of the resistivity ρ of the original PVA, irradiated PVA, and PVA/CdS nanocomposites shows that the nanocomposites formed in 5 and 10 cycles and treated with a dose of 200 kGy due to a decrease in mobility polymer chains due to radiation crosslinking have a relatively high thermal stability. The thermal stability of the composites increases by ~20-22K compared to the irradiated polymer and by ~40K compared to the original polymer. An increase in the temperature stability of PVA/CdS nanocomposites can be assessed as a significant improvement in their performance as electrical materials.

6. As a result of studying the effect of polymer-based plasticizers on the technological properties of isoprene and NBR elastomers, it was found that when using polymer-oil-based plasticizers obtained by the radiation-chemical method, the process of mechanical dissolution improves, in the process of bond vulcanization (C-C, C-S-C) increase, the density of the network of chains increases, which leads to an improvement in the physical and mechanical properties of elastomeric composites, and increases resistance to aggressive liquid media. The results obtained are of practical importance and can be recommended for reducing friction during the movement of gear wheels of machine-building, automobile and railway transport.

7. The parameters of the recently developed MLFD-3NM-2 deep-pixel avalanche photodiodes were studied, which showed that at the optimal operating voltage they have a 2.5 times higher gain, an overvoltage range of ~ 42%, and a photon detection efficiency of ~ 40% compared to the previous one. analogue (MLFD-3NM-1) is getting better. Based on the results obtained, the possibility of creating better quality scintillation gamma spectrometers based on the newly developed MLPD-3NM-2 photodiodes is shown.

Problem III. Radiation-nanocatalytic conversion of hydrocarbons and water, application of radiation technologies for solving environmental problems and nuclear-hydrogen energy

1. In radiation-stimulated polymerization processes in olefin-containing liquid binary systems, the proportion of the post-radiation effect that occurs 5000 hours after the cessation of irradiation increases by 15–20%, depending on the initial olefin concentration and irradiation dose.

2. The process of obtaining hydrogen and olefins from petroleum fractions by radiation-thermal exposure has been studied and it has been shown that under optimal conditions, the activation energy decreases from 150 kJ/mol to 20 kJ/mol, which leads to a decrease in the process temperature to 350 degrees and, thus, allowed to reduce carbon emissions by 200 kg per tonne of raw materials. Carbon emissions are reduced to zero by using thermal energy from alternative energy sources.

3. Nano - Al2O3, included in an aqueous medium containing toxic components (PCBs) in the process of radiolysis of the system, which characterizes the transformation with an increase in the absorbed dose, the pH index at a dose of 140 kGy decreases from 5.3 to 3.9, and the OST index is 1266 mg /l is reduced to 182 mg/l. This decrease is explained by the reaction of defects (g = 2.0045, ∆B = 10.7 G), (g = 2.0076, ∆B = 10.7 G) created by gamma radiation on the oxide surface with adsorbed molecules of the toxic component by TL and EPR.

4. Radiation-catalytic methods have been developed for obtaining a practical light hydrocarbon-gas (C2-C4) fraction and hydrogen, which is a universal energy carrier with an additional high yield from hexane in the presence of nano-ZrO2, it has been established that the radiation-chemical yield of hydrogen in comparison with a homogeneous phase (G(H2) =5.3 molecules/100 eV), in the range T=373÷473K increased by more than 4-7 times (G(H2) =19.6÷36.4 molecules/100 eV), and for hydrocarbons (G(CxHy) ~ 1.4 times.

5. It has been determined that the surface activity of catalysts initially treated with an electric discharge in an oxygen environment is higher than that of conventional catalysts at absorbed dose values D≤141 kGy. Thus, according to the data of thermoluminescent and thermophysical analysis in modified catalysts, the intensity of surface efficiency increases by 3.2 times, the volume of surface sorption is 1.6 times higher, and the volume of the product formed in the liquid phase in the processes of hydrocarbon conversion is 1.6 times higher.

IV ISSUE: obtain of energy carriers, development of scientific bases of utilization of renewable energy sources in energy supply in production and household

1. As a result of statistical studies carried out in the liberated territories, the technical indicators for the production of hydrogen and hydrogen-containing gases from biomass in a solar-thermal heliogas generator were calculated. It is shown that due to an average of 6.4 million kWh of thermal energy per thousand square meters of falling thermal energy per year, it will be possible to gasify 1.2 million tons of biomass and obtain H2 and H2-containing gas, with up to 33% of the energy potential of this fuel comes from solar energy. At the same time, CO2 emissions are reduced by up to 3,000 tons.

2. The possibility of obtaining high-calorie gas (H2, CH4, CO) mixtures by the influence of solar energy on biomass has been investigated. Biomass and solar energy are environmentally friendly sources, and their interaction results in high-energy gases (H2, CH4, CO), which shows the economic efficiency of this method. Biomass is energy intensive due to its high lignin content, and residual ash can be used as a fertilizer.
