AbstractData on the change in the rate of stratospheric ozone depletion in the Ox, HOx, NOx, ClOx, and BrOx catalytic cycles as a result of a change in the stratospheric temperature caused by global warming in 2100 compared with 2000 were presented. The altitude profiles of the concentrations of minor atmospheric components and temperature were cal...

AbstractThe search for ways to predict earthquakes, including predicting the point in time when they will occur and their possible coordinates and energy, is a global scientific problem. Researchers have discovered a number of natural phenomena that can be considered their precursors. Changes that occur in Earth’s ionosphere due to the emissions of...

Abstract—The atmospheric gas disturbance effect is modeled using the problem of the cutoff mode of the propagation of an acoustic wave. The atmosphere is approximately described as a 1D multilayer with an exponential density structure in each layer. The cutoff mode determining the propagation direction is defined at the layer boundaries and at the ...

AbstractThe efficiency of nanostructured 85% ZnO–15% In2O3 and 85% ZnO–12% In2O3–3% Fe2O3 systems in the detection of ethanol vapor at concentrations of 25 to 104 ppm in air is studied. Under experimental conditions, both systems are characterized by high stability and sensitivity that almost do not change in the presence of water vapor. At 370°С, ...

AbstractThe Cr–carbon nanotubes and Cr–boron nitride nanotubesas novel catalysts were used to find out the details of mechanisms of CN oxidation. The oxidation of CN molecule can process via Cr–CNT and Cr–BNNT catalysts through the Langmuir–Hinshelwood (LH) and Eley–Rideal (ER) mechanisms. The CN molecule joins to Cr atom and Cr–surface–\documentcl...

AbstractThe paper presents the results of a numerical simulation of ionospheric disturbances caused by a point thermospheric heat source, which mimic the dissipation effect of acoustic-gravity waves propagating from the region of a meteorological storm. It is shown that ionospheric effects have an extensive spatial structure and are more pronounced...

AbstractUsing density functional theory with the hybrid functional B3LYP in the 6-311++G(d, p) basis set, the Fukui functions were calculated for hydrogen atoms of CH bonds of 2-butanol in the cases of electrophilic and nucleophilic attacks, transition states were located, and the activation energies and enthalpies were computed for elementary reac...

Abstract—Molybdenum is a refractory metal, with a melting point of 2900 K. Its alloys with B and Si, obtained via powder metallurgy, have high heat resistance and have potential use in aircraft engine building. In this paper, the authors examined the possibility of using centrifugal SHS-metallurgy for the production of Mo–Si–B. To synthesize Mo–Si–...

Abstract—The effect of the boiling state on the reaction mechanism of 11 free radicals formed upon irradiation of 1-propanol with 8 MeV accelerated electrons is considered. Compared to radiolysis at room temperature, radiolysis at boiling results in an increase in 1-propanol degradation yield from (10.1 ± 0.9) to (13.3 ± 0.9) molecule/100 eV. Boili...
