Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(Royal Soc Chemistry, Cambridge, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
Comparison of open porous copper structures obtained by the different current regimes of electrolysis
(Elsevier Science Bv, Amsterdam, 2012)
Formation of open porous copper structures by the electrodeposition processes in the hydrogen code-position range was considered. Morphologies of copper deposits obtained by the reversing current (RC) regimes at the same ...
Nature of structural changes in LSM-YSZ nanocomposite material during thermal treatments
(Elsevier Science Sa, Lausanne, 2004)
Nanocomposite powders in the system (La1-xSx)(a)MnO3-YSZ((1-y)) [LSM-YSZ], as an attractive cathode material for high operating solid oxide fuel cell (SOFC), were obtained through ultrasonic spray pyrolysis (1.7 MHz) method. ...
Application of the general theory of disperse deposits formation in an investigation of mechanism of zinc electrodeposition from the alkaline electrolytes
(Elsevier Science Sa, Lausanne, 2017)
In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA ...
Preparation of nanostructured Zn-Cr-O spinel powders by ultrasonic spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2001)
Ultrasonic spray pyrolysis (1.7 MHz) has been applied for the generation of zinc chromium oxide submicronic (470 nm) particles from the corresponding metal nitrate solution. Heterogeneous gas-liquid/solid chemical reactions ...
A comparative study of antioxidative activities of cell-wall polysaccharides
(Elsevier Sci Ltd, Oxford, 2011)
Oxidative burst in plants is elicited by biotic and abiotic stressors. Analogously to some monosaccharides which act as intracellular antioxidants, cell-wall polysaccharides may be in charge of buffering free-radical ...
Immobilization of Horseradish Peroxidase on Macroporous Glycidyl-Based Copolymers with Different Surface Characteristics for the Removal of Phenol
(Springer, New York, 2022)
Novel macroporous copolymers of glycidyl methacrylate and ethylene glycol dimethacrylate with mean pore size diameters ranging from 150 to 310 nm were synthesized by dispersion polymerization and modified with ethylenediamine. ...
A possible mechanism of formation of flower-like MgO/Mg(OH)(2) structures by galvanostatic molten salt electrolysis: The concept of local diffusion fields
(Elsevier Science Sa, Lausanne, 2019)
The processes of electrodeposition from magnesium nitrate hexahydrate melt by galvanostatic regime of electrolysis have been analyzed. The structure of the formed particles was examined by X-ray diffraction (XRD), which ...
Comparative morphological and crystallographic analysis of copper powders obtained under different electrolysis conditions
(Elsevier Science Bv, Amsterdam, 2019)
Production of copper powders by the potentiostatic electrolysis under different hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction ...
The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
