Influence of electron irradiation on mechanical properties of epoxy polymers

Udovytska, Yu.A.; Luniov, S.V.; Maslyuk, V.T.; Megela, I.G. (KSU Publ., 2020-09-30)

The effect of different absorbed doses of electron irradiation with the energy of 12 MeV and heat treatment on the mechanical properties of ED-20 epoxy-dianic resin with hardener PEPA (11, 12 and 13 parts by weight per ...
Mathematical modeling of the initiation and spread of forest fires and their impact on buildings and structures

Perminov, V.A.; Fryanova, K.O. (KSU Publ., 2020-09-30)

Currently, methods of mathematical modeling are used to study processes in emergency situations. Forest fires are extremely complex and destructive natural phenomena which depend on availability of fuel, meteorological and ...
Optical properties of ablated graphene oxide in aqueous dispersions

Seliverstova, E.V.; Ibrayev, N.Kh.; Temirbayeva, D.A.; Omarova, G.S. (KSU Publ., 2020-09-30)

The effect of laser radiation on the structural and optical properties of graphene oxide dispersed in water was studied. It was shown that under laser ablation a significant reduction in the size of graphene oxide sheets ...

Rudenkov, A.S.; Yarmolenko, M.A.; Rogachev, A.A.; Surzhikov, A.P.; Luchnikov, A.P.; Frolova, O.A. (KSU Publ., 2020-09-30)

Peculiarities of forming of iron oxide coatings with reinforced carbon nanostructures from gas phase generated by laser dispersion of composite target were explored. Influence of technological modes of heat treatment on ...
Spectroscopy of nanoscale crystalline structural elements

Borodin, Y.V.; Sysolov, K.V.; Rande, V.R.; Vavilova, G.V.; Starý, O. (KSU Publ., 2020-09-30)

The study of structural elements, nanoparticles, microblocks and other nanoscale objects was an important part of the study of crystals non-equilibrium properties. The behavior of nanoscale structures allows us to judge ...
Structural properties of carbon composites doped with boron

Piliptsou, D.G.; Rudenkov, A.S.; Rogachev, A.V.; Hong, J.X.; Kulesh, Е.А.; Surzhikov, A.P.; Luchnikov, A.P.; Frolova, O.A. (KSU Publ., 2020-09-30)

The article considers morphology, chemical and phase composition of composite boro-carbon coatings, received by ion-plasma synthesis, depending on the boron content. Specimens of carbon coating doped with boron were ...
The effect of electric transport properties of titanium dioxide nanostructures on their photocatalytic activity

Serikov, T.M. (KSU Publ., 2020-09-30)

Annotation. Films formed by nanoparticles, nanorods and nanotubes of titanium dioxide with a thickness of 3.9, 4.0 and 4.1 μm, respectively, with an area of 2 cm2 were obtained by various methods. Nanostructures were ...
The effect of three-minute exposure of oxygen plasma on the properties of tin oxide films

Dmitriyeva, E.A.; Lebedev, I.A.; Grushevskaya, E.A.; Murzalinov, D.O.; Serikkanov, A.S.; Tompakova, N.M.; Fedosimova, A.I.; Temiraliev, A.T. (KSU Publ., 2020-09-30)

Research devoted to the effect of three-minute exposure of oxygen plasma on the properties of tin oxide films investigation. The films were obtained by sol-gel method from five-water tin tetrachloride solution. The ...
Theoretical aspects of transient temperature on cubic crystal surface in a photoacoustic effect

Sarode, A.P.; Mahajan, O.H. (KSU Publ., 2020-09-30)

In photoacoustic effect, the solid sample absorbs a fraction of the radiation falling upon it and excitation process occurs. The type of excitation depends on the energy of the incident radiation. The relaxation ...
