Neutron-Tomographic Study Of The Structural Features Of A Bronze Mirror Found In The Akterek Burial Complex, N. Torezhanova, O. Myakisheva, B. Mukhametuly, M. Kenessarin, R. Baitugulov, A. K. Bekbayev, K. M. Nazarov
Neutron-Tomographic Study Of The Structural Features Of A Bronze Mirror Found In The Akterek Burial Complex, N. Torezhanova, O. Myakisheva, B. Mukhametuly, M. Kenessarin, R. Baitugulov, A. K. Bekbayev, K. M. Nazarov
Eurasian Journal of Physics and Functional Materials
This work presents a study on the structure of a bronze mirror found in the Akterek burial complex by using neutron radiography and tomography. The manufacturing features and the physical state of this mirror was analyzed by three-dimensional model. It turned out that the rim on the edge was made of a different alloy, and the border between the rim and the base of the mirror is also visually visible. The morphological features and spatial distribution of pores and voids formed during secondary casting with the application of various patterns and ornaments have been studied in detail. The neutron tomography …

The copper Heliocles coin and two silver Demetrius coins dated to the II century BC from the archaeological works of the Uzundara fortress of the Greco-Bactrian Kingdom were studied using non-destructive structural diagnostics methods. The phase analysis of the coins was performed using the X-ray diffraction method. Also, the spatial distribution of the internal components of the coins was investigated by neutron imaging methods. It has been established that the dominant phase of the Heliocles coin is copper, however, a small volume of patina was found. It is mainly represented by tenorite CuO phase. The neutron tomography method indicates a …

Formation Of High Strength And Corrosion Resistance Composition Cover On The Surface Of Casting, R. J. Bashirov, F. R. Rasulov
Eurasian Journal of Physics and Functional Materials
The article is devoted in the casting process of alloying the surface of castings by impregnating the powder composition with liquid iron when pouring the last casting mold. It is established that the impregnability of powder with liquid iron depends on the temperature of the metal, the thickness of the coatings and the particle size composition of the powders.
Effect Of Graphene Oxide On Spectral-Luminescenct Properties Of Xanthene Dye, E. V. Seliverstova, E. Zh. Alikhaidarova, N. Kh. Ibrayev
Effect Of Graphene Oxide On Spectral-Luminescenct Properties Of Xanthene Dye, E. V. Seliverstova, E. Zh. Alikhaidarova, N. Kh. Ibrayev
Eurasian Journal of Physics and Functional Materials
The effect of graphene oxide on the spectral and luminescent properties of xanthene dyes was studied. During the interaction of graphene oxide (GO) with a cationic dye, aggregation of Rhodamine 6G occurs, which is expressed as an increase in the optical density of the short-wavelength shoulder in the absorption spectrum of the dye. GO sheets can act as adsorption centers for dye molecules due to the influence of the Coulomb and intermolecular forces between GO and Rhodamine 6G. This effect is practically not pronounced for anionic dyes. The quenching of the dye fluorescence intensity in the presence of GO was …

Analysis Procedures In Deriving Of The Differential Cross Section Of The Reaction Pp ! {Pp}Sp0 At Energies 1.6–2.4 Gev, B. S. Baimurzinova, D. A. Tsirkov
Eurasian Journal of Physics and Functional Materials
The reaction pp → {pp}sp0 , where {pp}s denotes a diproton, i.e. an unbound interacting proton pair in the 1S0 , state, was investigated in order to obtain a differential cross section ds/dW at small angles
in the energy range 1.6–2.4 GeV. This work is intended for the presentation of the main procedures in the processing of experimental data.
