AB  - The optimization of the anodization process of Ti substrate for in situ synthesis of hydroxyapatite/titanium oxide composite coatings on titanium substrate was accomplished. The anodization was performed under 30, 60 and 90 V cell voltage, and the morphology of treated surface, as well as linear and surface roughness, were analysed by field emission-scanning electron micro­scopy, atomic force microscopy and roughness tester. It was shown by linear and surface roughness analyses that titanium anodized under 60 V has the high­est roughness, whereas at 90 V the flattening of the surface occurs. As the highest surface roughness results emerged at 60 V, the novel process of com­po­site anHAp/TiO2 coating synthesis, which comprises simultaneous processes of TiO2 formation and HAp deposition, as well as HAp impregnation within TiO2 surface layer, was performed at this voltage. Ti substrate surface was completely covered by composite coating, with no visible cracks. The adhesion quantified according to ASTM D3359-02 standard is considerably improved with respect to the coatings obtained by cathaphoretic processes, with no need of subsequent sintering.

AB  - Considerable promotion of RuO2 hosted by perovskite-like structure of rare earth–CoO3 composite and vice versa supercapacitive performances is reported. Spherical, sub-μm-sized, regular spheres of La0.6Sr0.4CoO3 (LSCO), were synthesized by ultrasonic spray pyrolysis. The sphere surface was subsequently hydrothermally doped by RuO2. LSCO and LSCO/RuO2 composites were investigated for their supercapacitive performances in alkaline solution. Microstructure and surface morphology were studied by SEM and XRD. It was found that amorphous Ru species decorate LSCO surface, and possibly incorporate partially into B-site of the LSCO lattice. Electrochemical characterization by cyclic voltammetry (CV), galvanostatic charge-discharge (G-C/DC) and electrochemical impedance spectroscopy (EIS) clearly revealed that capacitive performances of LSCO are considerably improved by addition of 20 mass. % of RuO2. The registered capacitance for LSCO/RuO2 reaches the values of pure RuO2, which reveals the promoting influence of LSCO on RuO2 pseudocapacitance. The EIS analysis showed that RuO2 catalyzes the redox transition of Co species, with simultaneous proportional increase in pseudocapacitive RuO2 abilities while being hosted by LSCO. This intrinsic interactive promotion introduces LSCO/RuO2 composite as unique supercapacitive material. G-C/DC curves showed that LSCO/RuO2 is of modest cyclability with respect to pure LSCO and RuO2, although the capacitance losses with cycling are acceptably low. © 2019 Elsevier Ltd

AB  - 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 revealed formation of MgO/Mg(OH)2 mixture by molten salt electrolysis. Morphologies of the produced deposits were characterized by scanning electron microscopy (SEM)technique. The flower-like forms constructed from very thin needles with sharp tips were predominately formed by electrodeposition at various current densities and with various amounts of electricity. Aside from that, holes formed from detached hydrogen bubbles of various shapes and sizes, from dish-like holes to those resulting in honeycomb-like structures were also observed. Mechanism of formation of the flower-like forms has been elucidated applying the general theory of disperse deposits formation which is based on the concept of local (spherical and cylindrical)diffusion fields. It is shown that the growth of the needles occurs under the conditions of predominant spherical diffusion control, while the contribution of the cylindrical diffusion to the final shapes was negligible. Comparison with morphologies of deposits obtained by electrodepositions from aqueous magnesium salt electrolytes was also made and discussed. © 2019 Elsevier B.V.

AB  - The processes of electrochemical deposition of magnesium oxide/hydroxide on glassy carbon (GC) electrode from magnesium nitrate hexahydrate melt have been investigated. A novel procedure predicting a possibility of direct formation of magnesium oxide during electrodeposition from the nitrate melt used is reported. XRD analysis of the obtained deposits showed the formation of magnesium oxide along with magnesium hydroxide. The electrodeposition of magnesium oxide/hydroxide commences in magnesium underpotential (UPD) and continues through the magnesium overpotential (OPD) region. Network of individual or intertwined very thin needles as well as those grouped in flower-like aggregates or honeycomb-like structures were formed in both magnesium UPD and OPD regions. Formation of the long needles was explained through theories of mechanisms of dendrite formation. Hydrogen evolution commences in the magnesium OPD region and increases with the applied overpotential. Holes observed in the deposit originated from the detached hydrogen bubbles. The number, shape and size of the hole strongly depended on both the applied cathodic potential and the hold time of electrodeposition. Magnesium oxides/hydroxides syntheses taking part simultaneously at various applied potentials are a result of reactions between magnesium cations and products of water and nitrate anions reduction processes. Chemical reactions responsible for direct formation of magnesium oxide observed are those of magnesium ions and oxygen ions, formed by nitrate reduction taking part in the close vicinity of the working electrode.

AB  - Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation by potassium hydroxide. Samples with considerably different surface and intrinsic micro-and mesoporous properties are obtained at different carbonization and activation conditions. The improvements of the capacitive properties are found upon increase in carbonization temperature, since it considerably influenced the specific surface area and the content of surface oxygen groups. Cyclic voltammetry experiments reveal the dependence of specific capacitance on the sweep rate due to the characteristic porous structure of the samples. The highest measured value in 1 M H2SO4 solution is 122 F g(-1). The electrochemical impedance data indicates eight-branch transmission line equivalent electric behavior of activated carbons.

Cyclic voltammetry experiments reveal the dependence of specific capacitance on the sweep rate due to the characteristic porous structure of the samples. The highest measured value in 1 M H2SO4 solution is 122 F g(-1). The electrochemical impedance data indicates eight-branch transmission line equivalent electric behavior of activated carbons.

AB  - TiO2 powder was synthesized by a forced hydrolysis process and used for the synthesis of Pt/TiO2 composite that is to be foreseen as an advanced electrode material. Pt was incorporated into the synthesized TiO2 from a Pt colloidal dispersion as a precursor prepared by a microwave- assisted polyol process. Physicochemical properties of TiO2 and TiO2- supported Pt were investigated by scanning electron microscopy, dynamic light scattering and X- ray spectroscopy and diffraction techniques. The properties of Pt/TiO2 composite are correlated to the basic voltammetric response of its thin-layer form. It was found that subsequent thermal treatment of synthesized TiO2, which caused crystallization into mainly rutile phase, is required for appropriate Pt incorporation. Although being appropriately loaded by Pt, and the voltammetric response is typical for Pt-based material, the voltammetry of Pt/TiO2 corresponded to much lower loadings.The possibility for Pt particles to be trapped inside TiO2 agglomerates is indicated. The catalyst usage from the synthesized Pt/TiO2 was found quite moderate due to this trapping.

AB  - Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating and coating/Al assembly brings new issues on Al corrosion and protection caused by unique properties of the sol-gel coating. The corrosion behaviour of bare Al and Al/CeO2 is investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to NaCl aqueous solution. The morphology and composition of the samples are examined by scanning electron microscopy and energy dispersive spectroscopy. EIS data showed greater corrosion resistance of CeO2-coated aluminium in comparison to bare Al at long exposure times. CeO2 coating does not hinder completely the corrosion processes on Al. The Al beneath CeO2 coating is subjected to intrinsic formation of a uniform protective coating/Al interphase, cross-linked by AlO(OH) fibre-like structures. They appear created by corrosive medium from the coating reversely gelled by NaCl solution. As the fibre network is created during exposure, Al becomes better protected than by spontaneous formation of porous passive layer of Al(OH)(3) on bare aluminium. Sol-gel ceria coatings thus improve corrosion resistance of aluminium during prolonged exposure to corrosive medium.

AB  - An ultrasonic irradiation was applied for the impregnation by chemical agents in the chemical activation process of new type of active carbon precursor. Plane tree seed, due to the unique fibrous structure and low cost is a promising eco-friendly raw material for the preparation of activated carbon materials. Ultrasonic irradiation was used for the impregnation step allowing the chemical activation by different agents: potassium or sodium hydroxide, hydrogen peroxide and pyrogallol. The porous structures were examined by nitrogen adsorption/desorption isotherms at 77 K and electrochemically by cyclic voltammetry. The textures of these materials were observed by scanning electron microscopy. The application of ultrasonic irradiation in the impregnation step increased surface area of the final material more than two times in comparison to the material which impregnation in the activation process was by conventional stirring. Ultrasonic irradiation enhances the chemical activation process and the activated carbon fibrous materials with nanoporous structure were obtained by impregnation of seeds with alkaline hydroxides. Total surface areas of these samples were 976 m(2) g(-1), and 1130 m(2) g(-1). These fibers have total specific capacitance as high as 125 F g(-1) and 53 F g(-1) which major fraction in both cases originate from internal micropores structure. (C) 2013 Elsevier B.V.
