Аннотация: The present paper reports on the preparation of three- and bilayer graphene and boron doped graphene defect-free large films by electrochemical synthesis in molten alkali chlorides. It is shown that the morphology and composition of the resulting graphene and boron doped graphene films with total boron concentration up to 57 at.% which can be carefully controlled by the parameters of the deposition process, i.e., boron carbide concentration, synthesis temperature, and the applied anodic current density, in particular. The Raman spectra of boron doped graphene reveal the additional characteristic boron peaks aside from the traditional graphene ones. The intensity of these boron peaks is shown to be affected by boron concentration in graphene.

    Application of Solid oxide proton-conducting electrolytes for amperometric analysis of hydrogen in H2+N2+H2O gas mixtures / A. Kalyakin, G. Fadeyev, A. Demin, E. Gorbova, A. Brouzgou, A.

ТВЕРДЫЕ ЭЛЕКТРОЛИТЫ -- ВОДОРОД -- ДАТЧИКИ
Аннотация: Amperometric hydrogen sensors based on proton-conducting solid electrolytes of La0.95Sr0.05YO3, CaTi0.95Sc0.05O3 and CaZr0,9Sc0.1O3 compositions are prepared and investigated in the present work. The influence of the sensor design on its own characteristics is also examined. It is shown that a solid electrolyte used in the form of discs with cavities significantly simplifies the design of this type of sensors. A sensor based on La0.95Sr0.05YO3 electrolyte with fully sealed junction between discs is suitable for the analysis of mixtures with high H2 content. It is found that by increasing H2 content from 10 to 98% the limiting current increases from 0.25 to 2.25 mA (at 750 mV). It is also found that the sensor based on La0.95Sr0.05YO3 with discs sealed in two points as well as the sensor based on CaZr0,9Sc0.1O3 with fully sealed junction are suitable for the analysis of mixtures with low H2 content (0.5-2%). For the above cases, the limiting current at 2% H2 reaches 3.5 and 0.5 mA (at 750 mV), respectively. CaTi0.95Sc0.05O3 is not suitable to be used as a hydrogen sensor. In all the examined systems, steam content does not affect sensors’ behavior and high operating temperatures (850 °C) increase the range of sensors’ hydrogen measuring concentration capacity.

Аннотация: The electrolyzers used to extract calcium from copper-calcium alloys at 0.5 to 3.0 kA were designed, manufactured, and utilized to study the process parameters more precisely. The pilot electrolysis device used to produce calcium from copper-calcium alloys at 12 to 15 kA was developed. The calcium production using the bipolar electrolyzer was proved to be possible and was experimentally tested.

Аннотация: The present paper is devoted to Ni-cermet degradation phenomena and places emphasis on experimental approaches and data handling. The resistivity of Ni-YSZ cermet (nickel and 8 mol.% yttria stabilized zirconia) anode substrates was monitored during 3000 h at 700 and 800 °C in a gas mixture of 80 vol.% water vapor and 20 vol.% hydrogen. The experimentally evaluated dependence of resistivity of the Ni-YSZ substrates can be well described by exponential decay functions. Post test analysis by image processing and XRF (X-ray fluorescence) analysis for characterization of the microstructure and elemental composition were carried out for virgin samples and after 300, 1000 and 3000 h of exposure time. The 3D-microstructure was reconstructed using an original spheres packing algorithm. Two processes leading to the Ni-YSZ degradation were observed: Ni-phase particle coarsening and volatilization. The effect of these processes on resistivity and such microstructure parameters as porosity, Ni-phase fraction, Ni and YSZ phases particle size distributions, triple phase boundary length, and tortuosity factor are considered in this paper.

Аннотация: The anisotropy of the growth rate and the morphology of the potassium-lithium oxide tungsten bronze single crystals during the electrolysis in the 0.30K2WO4-0.25Li2WO4-0.45WO3 melt at 700 C under potentiostatic conditions in the overpotential range from 0 to 70 mV have been studied. An anomalous decrease in the growth rate of the {1010} face has been observed at overpotential values above 30 mV. It was decided that the process of selforganization takes place. The mechanism of such selforganization exists to be the selection of electroconductivity between separate blocks of the crystal

Аннотация: An analysis of the operation of an amperometric sensor with a diffusion channel at unsteady pressure of the analysed gas was carried out. Relations between sensor parameters, pressure jamp and sensor current were established. It was shown that the main reason for the distortion of a sensor reading is a large convective gas flow into the sensor chamber through the channel due to a gas pressure jamp. On the basis of the analysis, it is demonstrated how to change the sensor parameters to eliminate the error in the sensor reading. This may be achieved by decreasing the sensor chamber volume or changing the diffusion channel parameters. Two types of diffusion channels are considered: a channel filled by a porous medium and a narrow plate channel. The relations obtained provide the basis for choosing the corresponding sensor parameters in order to attain a given accuracy of the oxygen concentration measurement for maximum expected pressure changes

MOLTEN SALT FLUORIDES -- BERYLLIUM REFERENCE ELECTRODE -- REDOX POTENTIAL
Аннотация: Existing designs of reference electrodes for potentiometric measurements in fluoride melts do not meet basic requirements of the long exposure corrosion tests to be performed. A new diaphragm-free three-electrode meter with a nonstationary (dynamic) beryllium reference electrode for the redox potential measurements was developed. Optimum conditions of forming dynamic beryllium reference electrode were determined in the laboratory tests in isothermal cell. The device for redox potential measurement was designed and it was shown that it is highly sensitive to changes redox potential within ±5 mV. Reliability and efficiency of diaphragm-free device with dynamic reference electrode was confirmed in the thermal convection corrosion loop operating more than 1200 h with molten 15LiF–58NaF–27BeF2 mixture (mol%) at a maximum temperature of about 700 °C.????

ТЕРМОДИНАМИКА -- КОЭФФИЦИЕНТ ДИФФУЗИИ
Аннотация: This work presents the electrochemical study of Cm(III) in fused 3LiCl–2KCl eutectic in the temperature range 723–923 K. Transient electrochemical techniques such as cyclic, square wave voltammetries, and chronopotentiometry have been used in order to investigate the reduction mechanism of curium ions up to metal. The results obtained show that the reduction reaction takes place in a single step . The diffusion coefficient of Cm3+ ions was determined by cyclic voltammetry at different temperatures by applying Berzins–Delahay equation. The validity of the Arrhenius law was also verified and the activation energy for diffusion was found to be 28.21 kJ mol-1. The apparent standard electrode potential of the redox couple Cm(III)/Cm(0) was found by chronopotentiometry at several temperatures. The thermodynamic properties of curium trichloride have also been calculated.??

ТОПЛИВНЫЕ ЭЛЕМЕНТЫ -- ПЕРЕНОС ПРОТОННЫЙ
Аннотация: This study examines potential benefits of adopting ultrashort optical pulses in fuel cell technology. General principles for jumping migration of protons in resonant laser fields have been elaborated. We find that, depending upon the frequency of phonon assistance, the effective activation energy for migration can be strongly diminished when excitation pulses are used. The obtained results indicate that at room temperature the picosecond-laser-induced proton transfer in rutile type oxides is much faster than that for thermal activation. Our estimates are in good agreement with time-resolved measurements for rutile samples excited by infrared light. The fundamentals of this transfer process are briefly analyzed in the light of structure diffusion and vibrational mode models. The most important conclusion to emerge from our work is that the use of the optical stimulation shows considerable promise as a means for decreasing the operating temperature of solid oxide fuel cells based on proton hopping transport.
