On the Self-Propagating High-Temperature Synthesis of a Ti–Si–C Composite Using FulleritesPleiades Publishing Ltd - Tập 17 - Trang 564-570 - 2022
R. M. Nikonova, N. S. Larionova, V. I. Lad’yanov
A 3Ti–Si–2C composite material is obtained by self-propagating high-temperature
synthesis, in which C60/70 fullerite is used as carbon. Its phase composition
and structure are investigated by X-ray diffraction and scanning electron
microscopy. It is shown that a composite containing TiC carbide, Ti5Si3Cx
carbosilicide, and Ti3SiC2 MAX phase as well as traces of titanium silicide
TiSi2 is formed as... hiện toàn bộ
Impedance of Structures with Non-uniform Current DistributionPleiades Publishing Ltd - - 2024
L. A. Shendrikova, N. S. Perov, N. A. Buznikov
The effect of giant magnetoimpedance in magnetic structure with inhomogeneous
electric current distribution is studied. A special design reduces the magnitude
of the intrinsic magnetic field outside the structure. The magnetoimpedance of
such a planar structure made of magnetically soft material with radial current
distribution has been investigated both theoretically and experimentally. The
theor... hiện toàn bộ
Mongols on the Don: Recreating Lost Historical Context by Scientific MethodsPleiades Publishing Ltd - Tập 16 - Trang 623-630 - 2021

Research into a destroyed burial site in Bol’shaya Elista balka in the
Remontnensky district of the Rostov oblast provides additional data on the
“biography” of a 45-year-old medieval man. The horseman warrior died in the late
13th century and was buried in the open steppe in Bol’shaya Elista balka. An
indirect indication of the warrior possibly being Mongol is the type of the
burial site: the gra... hiện toàn bộ
Fabrication of 3D Porous Graphene@SnO2 Aerogel via In Situ Gamma Ray Irradiation Induced Self-AssemblyPleiades Publishing Ltd - Tập 17 - Trang 59-63 - 2022
Kai Fan, Chun Liu, Linfan Li, Jihao Li
A environmentally-friendly and facile approach for the fabrication of graphene
nano-sheets decorated with SnO2 composite aerogel (GA@SnO2) has been developed
by γ-ray irradiation induced self-assembly under the protection of N2 gas at
room temperature. The graphene oxide (GO) and Sn2+ ions are simultaneously
reduced and oxidized respectively by the electrons and hydroxyl radical
generated from the... hiện toàn bộ
Microemulsions in Systems with Lecithin and Oleic Acid for Medical UsePleiades Publishing Ltd - Tập 18 - Trang 283-289 - 2023
N. M. Murashova, E. S. Trofimova, L. A. Gagueva
Reverse microemulsions for use in medicine and cosmetics in systems containing
lecithin (a mixture of phospholipids with a lecithin content of ~22 wt %), oleic
acid, vaseline oil, vegetable oil, essential oil (in an amount of less than 5 wt
%), and water are developed. The hydrodynamic diameter of the droplets of the
microemulsions ranges from 15 to 80 nm. The microemulsions are stable when
heated... hiện toàn bộ
Chemical Composition of Metal Objects with Eastern European Champlevé EnamelsPleiades Publishing Ltd - Tập 16 - Trang 561-565 - 2021
I. A. Saprykina
The article is devoted to the results of the study of the chemical composition
of non-ferrous metal objects belonging to the horizon of East European champlevé
enamels (2nd–3rd/4th centuries). The sample currently contains 270 samples,
items come from excavations of settlements and collections from the territories
of the Volga–Oka interfluve, the Dnieper region, and the forest-steppe Don
region. T... hiện toàn bộ
Phase Composition and Thermoelectric Properties of Materials Based on Cu2 – xSe (0.03 ≤ x ≤ 0.23)Pleiades Publishing Ltd - Tập 16 - Trang 351-356 - 2021

The phase composition and thermoelectric properties of Cu2 – xSe samples with
different deviations from the stoichiometric composition (x = 0.03, 0.08, 0.13,
0.18, and 0.23) are studied. Bulk thermoelectric materials based on Cu2 – xSe
are synthesized by spark plasma sintering. The phase composition is studied
using the X-ray diffraction method. Depending on the chemical composition, the
materials... hiện toàn bộ
