Аннотация: A method for synthesis of carbon nanostructures in a high-frequency arc discharge in the flow of helium (3–4 L/min) is presented. It is shown that the plasma-chemical synthesis of fullerenes and endohedral metal fullerenes (EMFs) can be controlled by changing helium pressure in the chamber. Temperature and electron concentration along the line normal to the discharge axis decrease upon moving away from the axis to the periphery; the larger the pressure, the sharper is the decrease in these parameters. The optimal helium pressure of 98 kPa was found in obtaining the Gd@C82 EMF which corresponds to the maximal EMF yield of 5 wt %. © 2016, Pleiades Publishing, Ltd.

Аннотация: A design of a plasma generator, the parameters of the resulting plasma, and the possibilities of its use for the synthesis of nanosized powders and optical emission spectroscopy are described. The device operation is based on the arc discharge of alternating current (66 kHz) in an argon jet between water-cooled metal electrodes. The discharge is stabilized by a flow of isolating gas (helium, nitrogen, air) and an axial magnetic field. The gas flow is fed tangentially to the discharge axis. The plasma between the electrodes has the shape of a cylinder remote from the chamber walls. The temperature and electron concentration in the cross section of the plasma cylinder vary along the radius and take the maximum and minimum values.

Antioxidant Activity and Toxicity of Fullerenols via Bioluminescence Signaling: Role of Oxygen Substituents / E. S. Kovel [et al.] // Int. J. Mol.

bioactive compound -- fullerenol -- antioxidant activity -- toxicity -- reactive oxygen species -- bioluminescence bioassay
Аннотация: Fullerenols are nanosized water-soluble polyhydroxylated derivatives of fullerenes, a specific allotropic form of carbon, bioactive compounds, and perspective basis for drug development. Our paper analyzes the antioxidant activity and toxicity of a series of fullerenols with different number of oxygen substituents. Two groups of fullerenols were under investigation: (1) C60Oy(OH)(x), C60,70Oy(OH)(x), where x+y = 24-28 and (2) C60,70Oy(OH)(x), Fe0,5C60Oy(OH)(x), Gd@C82Oy(OH)(x), where x+y = 40-42. Bioluminescent cellular and enzymatic assays (luminous marine bacteria and their enzymatic reactions, respectively) were applied to monitor toxicity in the model fullerenol solutions and bioluminescence was applied as a signaling physiological parameter. The inhibiting concentrations of the fullerenols were determined, revealing the fullerenols' toxic effects. Antioxidant fullerenol' ability was studied in solutions of model oxidizer, 1,4-benzoquinone, and detoxification coefficients of general and oxidative types (D-GT and D-OxT) were calculated. All fullerenols produced toxic effect at high concentrations (>0.01 g L-1), while their antioxidant activity was demonstrated at low and ultralow concentrations (<0.001 g L-1). Quantitative toxic and antioxidant characteristics of the fullerenols (effective concentrations, concentration ranges, D-GT, and D-OxT) were found to depend on the number of oxygen substituents. Lower toxicity and higher antioxidant activity were determined in solutions of fullerenols with fewer oxygen substituents (x+y ⋍ 24-28). The differences in fullerenol properties were attributed to their catalytic activity due to reversible electron acceptance, radical trapping, and balance of reactive oxygen species in aqueous solutions. The results provide pharmaceutical sciences with a basis for selection of carbon nanoparticles with appropriate toxic and antioxidant characteristics. Based on the results, we recommend, to reduce the toxicity of prospective endohedral gadolinium-fullerenol preparations Gd@C82Oy(OH)(x), decreasing the number of oxygen groups to x+y ⋍ 24-28. The potential of bioluminescence methods to compare toxic and antioxidant characteristics of carbon nanostructures were demonstrated.

Biological activity of carbonic nano-structures—comparison via enzymatic bioassay / A. S. Sachkova [et al.] // J. Soils Sed. - 2019. - Vol. 19, Is. 6. - P. 2689–2696, DOI 10.1007/s11368-018-2134-9. - Cited References: 38. - This work was supported by the state budget allocated to the fundamental research at the Russian Academy of Sciences, project 0356-2017-0017; PRAN-32, Program: “Nanostructures: physics, chemistry, biology, technological basis.” Study of ROS involvement to antioxidant activity of humic substances was supported by the Russian Science Foundation, grant 16-14-10115. . - ISSN 1439-0108
Кл.слова (ненормированные):
Antioxidant activity -- Bioactive compounds -- Fullerenol -- Humic substances -- Toxicity -- Reactive oxygen species
Аннотация: Purpose: The aim of the work is to compare the biological activity of carbonic nano-structures of natural and artificial origination, namely, humic substances (HS) and fullerenols. Materials and methods: The representative of the fullerenol group, С60Оy(OH)x where у + x = 20–22, was chosen. Enzyme-based luminescent bioassay was applied to evaluate toxicity and antioxidant properties of HS and fullerenol (F); chemiluminescent luminol method was used to study a content of reactive oxygen species (ROS) in the solutions. Toxicity of the bioactive compounds was evaluated using effective concentrations ЕС50; detoxification coefficients DOxT were applied to study and compare antioxidant activity of the compounds. Antioxidant activity and ranges of active concentrations of the bioactive compounds were determined in model solutions of organic and inorganic oxidizers—1,4-benzoquinone and potassium ferricianide. Results and discussion: Values of ЕС50 revealed higher toxicity of HS than F (0.005 and 0.108 g L−1, respectively); detoxifying concentrations of F were found to be lower. Antioxidant ability of HS was demonstrated to be time-dependent; the 50-min preliminary incubation in oxidizer solutions was suggested as optimal for the detoxification procedure. On the contrary, F’ antioxidant effect demonstrated independency on time. Antioxidant effect of HS did not depend on amphiphilic characteristics of the media (values of DOxT were 1.3 in the solutions of organic and inorganic oxidizers), while this of F was found to depend: it was maximal (DOxT = 2.0) in solutions of organic oxidizer, 1,4-benzoquinone. Conclusions: Both HS and F demonstrated toxicity and low-concentration antioxidant ability; however, quantitative characteristics of their effects were different. The differences were explained with HS polyfunctionality, higher ability to decrease ROS content, non-rigidity, and diffusion restrictions in their solutions. Antioxidant effect of the bioactive compounds was presumably attributed to catalytic redox activity of their π-fragments. The paper demonstrates a high potential of luminescent enzymatic bioassay to study biological activity of nano-structures of natural and artificial origination.

Аннотация: A bioluminescent assay based on a system of coupled enzymatic reactions catalyzed by bacterial luciferase and NADH:FMN-oxidoreductase was developed to monitor toxicity and antioxidant activity of bioactive compounds. The assay enables studying toxic effects at the level of biomolecules and physicochemical processes, as well as determining the toxicity of general and oxidative types. Toxic and detoxifying effects of bioactive compounds were studied. Fullerenols, perspective pharmaceutical agents, nanosized particles, water-soluble polyhydroxylated fullerene-60 derivatives were chosen as bioactive compounds. Two homologous fullerenols with different number and type of substituents, C60O2–4(OH)20–24 and Fe0.5C60(OH) xOy (x + y = 40–42), were used. They suppressed bioluminescent intensity at concentrations 0.01 g L−1 and 0.001 g L−1 for C60O2–4(OH)20-24 and Fe0.5C60(OH)xOy, respectively; hence, a lower toxicity of C60O2–4(OH)20–24 was demonstrated. Antioxidant activity of fullerenols was studied in model solutions of organic and inorganic oxidizers; changes in toxicities of general and oxidative type were determined; detoxification coefficients were calculated. Fullerenol C60O2–4(OH)20–24 revealed higher antioxidant ability at concentrations 10−17−10−5 g L−1. The difference in the toxicity and antioxidant activity of fullerenols was explained through their electron donor/acceptor properties and different catalytic activity. Principles of bioluminescent enzyme assay application for evaluating the toxic effect and antioxidant activity of bioactive compounds were summarized and the procedure steps were described.

Аннотация: The nickel particles with the mean size about 10-20 nm coated with carbon were extracted by the treatment of the carbon condensate with nitric and hydrochloric acids. The initial carbon condensate containing nickel nanoparticles with a graphite conversion was synthesized in the high-frequency carbon-helium arc plasma at ambient pressure with the nickel nanoparticles as a catalyst. The nickel content in the nanoparticles was 84.6 wt %. Magnetic properties of the nanoparticles are characterized by the high hysteresis and thermal stability. The sample of compacted nanoparticles is characterized by electrical resistance much higher than it in of compacted initial condensate.

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: In this paper, we study particles with metallic core (magnesium) - metal shell (nickel) structure, synthesized in metal-containing plasma of high frequency arc discharge. X-ray diffraction analysis, X-ray fluorescence analysis and scanning electron microscopy show that the particles have a uniform nickel shell, which is also indirectly confirmed by comparing the results of hydrogenation of Mg and Mg@Ni particles. Measurement of volume magnetization indicates that shell thickness of most particles is not more than 22 nm.
В данной работе исследованы частицы со структурой металлическое ядро (магний) - металлическая оболочка (никель), полученные в металлсодержащей высокочастотной плазме дугового разряда. Методами рентгенофазового анализа, рентгенофлуоресцентного анализа, сканирующей электронной микроскопии показано, что частицы имеют сплошную никелевую оболочку, что также косвенно подтверждается сравнением результатов гидрирования частиц Mg и Mg@Ni. С помощью измерений объемной намагниченности установлено, что наибольшая часть частиц имеет толщину оболочек не более 22 нм.
