Fullerene synthesis -- alternating current -- direct current
Аннотация: The results of the effect of helium pressure in the chamber on the amount and composition of the produced fullerenes (C60, C70, etc.) synthesized in the arc plasma with graphite electrodes are presented. The findings obtained when the arc is powered by a direct (DC) and alternating (AC) currents of low frequency were compared in the same chamber with the electrodes located at the same angle to each other. These two methods are drastically different. The complete conversion of graphite into fullerene soot in AC occurs, but a part of the graphite is converted into a cathode deposit that does not contain fullerenes in DC, the relative amount of which increases when decreasing the helium pressure in the chamber. The highest fullerene content in fullerene soot of 10.2 wt.% is produced at a pressure of 127.5 kPa in AC arc, but in DC arc, the highest content of fullerenes in fullerene soot of 8.3 wt.% is produced at a pressure of 33.3 kPa.

Controlled synthesis of fullerenes and endohedral metallofullerenes in high frequency arc discharge / G. Churilov [et al.] // Fuller. Nanotub. Carbon Nanostruct. - 2016. - Vol. 24, Is. 11. - P. 675-678, DOI 10.1080/1536383X.2016.1207062. - Cited References: 16. - The work is supported by the Ministry of Education and Science of Russia (Russian-Japanese joined project, Agreement № 14.613.21.0010, ID RFMEFI61314X0010). . - ISSN 1536-383X

Fullerene -- Endohedral metallofullerenes -- High frequency arc discharge -- Pressure -- Mass spectrum
Аннотация: The article presents the high-frequency arc discharge setup operating in helium atmosphere and applicable for the syntheses of carbon condensate with different dispersion and structure, along with fullerenes and endohedral metallofullerenes. It also highlights how the change of helium pressure in chamber can control the amount and composition of products in carbon condensate. The setup can be applied for the purposes of analysis, for instance in order to obtain information about the process of fullerenes and endohedral met-allofullerenes formation. Also, the fact that the yield of higher fullerenes is increasing with the pressure rise, whereas the yield of endohedral metallofullerenes is decreasing suggests different formation mechanisms. © 2016 Taylor & Francis Group, LLC.

Аннотация: Polymer-based dielectric capacitors play a notable part in the practical application of energy storage devices. Graphene oxide (GO) nanosheets can improve the dielectric properties of polymer-based composites. However, the breakdown strength will greatly reduce with the increase of GO content. Hence, the construction of sandwich structure can enhance the breakdown strength without reducing the dielectric constant. Herein, single-layered and sandwich-structured poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-CTFE)) nanocomposites with low content of GO nanosheets (<1.0 wt%) are prepared via employing a straightforward casting method. Compared with the single-layered composites and pure P(VDF-CTFE), the sandwich-structured composites exhibit comprehensively better performance compared. The sandwich-structured composite with 0.4 wt% GO nanosheets show an excellent dielectric constant of 13.6 (at 1 kHz) and an outstanding discharged energy density of 8.25 J cm−3 at 3400 kV cm−1. These results demonstrate that the growth of the dielectric properties is owing to 2D GO nanosheets and the enhancement of breakdown strength due to the sandwich structure. The results from finite element simulation provide theoretical support for the design of high energy density composites.

Investigation of microstructural features, phase composition, and magnetic characteristics of YBCO-based composites and additives of CuO non-superconducting component prepared in low-pressure arc discharge plasma / I. V. Karpov, A. V. Ushakov, A. A. Lepeshev [et al.] // Inorg. Mater.: Appl. Res. - 2021. - Vol. 12, Is. 1. - P. 142-146, DOI 10.1134/S2075113321010172. - Cited References: 12. - This work was supported by the Russian Science Foundation (project no. 16-19-10054) . - ISSN 2075-1133

low-pressure arc discharge plasma -- CuO nanopowder -- pinning centers -- high-temperature superconductor
Аннотация: A method making it possible to form HTS ceramics of non-superconducting coating consisting of self-organizing CuO crystals, whose sizes are less than the coherence length, i.e., within several tens of nanometers, has been developed. It has been shown that the combination of self-organizing structures in the form of whiskers and nanoparticles which arise as a result of combined sintering of YBa2Cu3O(7–x) powders and electric arc CuO nanopowders results in a significant increase in the current density and appearance of peak effect at high magnetic fields. Very high current density arises from the complex vortex pinning, where whisker defects provide high pinning energy and nanoparticles suppress flux creep. The morphology of such structures can be controlled by a simple change in the concentration of nanodisperse additives. It has been shown that 20 wt % of CuO additive is optimal.

Superconducting polycrystals -- YBCO ceramics -- Critical current -- Magnetic properties
Аннотация: The aim of this paper was to study the effect of nanoscale inclusions of CuO as the second ingredient of composites on transport properties of superconducting YBa2Cu3O7 polycrystals. The samples of YBa2Cu3O7−δ with different content of CuO nanoparticles were synthesized. The analysis of the magnetic properties was carried out within the extended critical state model. It was found that the addition of 0.5 and 1% of CuO nanoparticles leads to an increase in the intragranular density of the critical current at T= 4.2 K. A further increase of x from 2 to 15% and more than 40% decreases the critical current density. The critical current density higher than in the reference sample was also found in the samples with x= 20% and x= 24%.

Аннотация: Results are presented from experimental studies of an ac (44-kHz) arc discharge excited in an atmospheric-pressure argon jet between two copper electrodes. The first (central) electrode is a water-cooled rod with an axial opening for argon injection, while the second electrode is a loop of a tube lying in a plane perpendicular to the axis of the central electrode. The argon radiation spectra are measured, and the characteristic intensity profiles of the spectral lines as functions of the distance from the end of the central electrode are determined. All the observed transitions in the 245- to 370-nm wavelength ran-e are identified.
