AB  - A novel anode based on PbO2-GNRs nanocomposites was synthesized in order to investigate the simultaneous electrochemical oxidation of phenolic compounds in a mixture of methyl and chloro substituted phenols in alkaline solution (pH = 8.3). The crystal structure, morphology and composition of the synthesized materials were characterized using X-ray powder diffraction (XRPD), field emission scanning electron microscopy with energy dispersive X-ray spectrometer (FESEM-EDX) and transmission electron microscopy (TEM). FESEM images confirmed the presence of PbO2 nanoparticles on the PbO2-GNRs composite. The cyclic voltammetry measurements of the PbO2-GNRs electrode in 0.1 M Na2SO4 electrolyte indicated the electrochemical oxidation of phenol via indirect mechanism by hydroxyl radicals. Electrolytic oxidation of phenolic compounds was performed under potentiostatic conditions at potentials 2.3 V and 3 V. Removal efficiency of phenolic compounds increased with increasing the time of electrolysis and applied potential, up to 78% for 300 min and potential of 3 V. GC–MS chromatograms confirmed that mechanism of phenolic compounds degradation is based on their dechlorination and demethylation followed by the process of aromatic ring degradation. Newly synthesized PbO2-GNRs as electrode material could be successfully implemented in wastewater treatment of phenolic compounds by the electrochemical oxidation process.

AB  - OBJECTIVE The objective was to determine the antibiofilm efficacy of Cymbopogon martinii and Thymus zygis essential oils and to estimate the disruption potential of oil-based endodontic irrigants on the multispecies biofilm formed in the root canals of extracted teeth. DESIGN The essential oils were characterized (GC-MS), while their antibacterial and cytotoxic properties were detected by microdilution and MTT assays. Particles sizes and polydispersity indices were determined for the irrigants. The isolates from root canals of pediatric patients were identified (MALDI-TOF). The multispecies biofilms were formed from Streptococcus mitis, Streptococcus sanguinis and Enterococcus faecalis. Antibiofilm properties of the essential oils and irrigants were determined by crystal violet and plate counting assay. Statistical analysis was performed by one-way ANOVA. RESULTS The screening of biofilm biomass revealed a disruption potential of C. martinii essential oil. The plate counting assay showed the efficacy of both oils in diminishing cell viability: high in biofilms (reduction of log10CFU was 2.75-2.87) and moderate in the planktons formed above. The essential oil-based irrigants showed the same antibiofilm activity as in the control (1.5 % sodium hypochlorite) for C. martini and almost 2-fold higher for T. zygis. Successive irrigations with 1.5 % sodium hypochlorite, saline and an oil-based irrigant was more efficient for C. martini than for the control (reductions of log10CFU was 1.69 and 1.14, respectively). CONCLUSIONS Notable activities achieved by essential oils and oil-based irrigants, particularly regarding C. martini, against the biofilm consisting of S. mitis, S. sanguinis, and E. faecalis, are expected to encourage further research in endodontics.

AB  - This paper investigates the ability of waste apricot (Prunus armeniaca) kernel shells (AKS) bio-char prepared by single-step carbonization process at 850 °C (residence time of 1 h) for possible removal of toxic elements and organic micro-pollutants. The experiment that was performed as well as parameters used proved to be optimal for bio-char production as adsorbing medium, where last issue is validated by multiform material characterization techniques. It has been shown that the produced bio-char possess highly-porous morphology features, with large specific surface area (328.570 m2 g−1). The obtained product was characterized by various pore sizes (including super-micropores and mesopores with maximum pore size of 2.24 nm) structures. Preliminary results are indicated that obtained bio-char can shows increased affinity to possible adsorption of the small organic molecule contaminants upgraded by its physico-chemical properties. Cost estimation of AKS bio-char production substantiated its cost effectiveness and its good physical and chemical properties for future design in batch adsorption and regeneration tests. It was established that AKS produced bio-char was 2.5 times cheaper than the commercially available activated carbon. Bio-char exhibits promising removal performances for potential adsorption of heavy metal and organic micro-pollutants from wastewaters systems, as indicated by material textures and spectroscopy measurements. © 2019 Elsevier Ltd

AB  - In this work, nickel (Ni) cathode for hydrogen evolution reaction (HER) in alkaline medium, was modified by a combination of in situ ionic activators, based on three d-metals (Co, Cu and Mo). Catalytic performance of new Co-Cu-Mo cathode was improved compared to pure Ni in view of both increased HER reaction rate and improved energy efficiency - reduction of energy consumption of a model electrolytic cell by 15%. We discussed obtained results in comparison with previously investigated similar systems (Ni-Co-Mo and Ni-Cu-Mo). In addition, we perform a detailed surface characterization by a series of experimental techniques (XRF, XRD, SEM, profilometry and EIS) and employ DFT calculations to provide a more detailed discussion of the origin of obtained catalytic performance. © 2019 Elsevier B.V.

AB  - Polycyclic aromatic hydrocarbons (PAHs) are denoted by International Agency for Research on Cancer as mutagens, teratogens and carcinogenic to humans. In 2013, Vinca Institute of Nuclear Sciences was hired to determine whether PAHs are present in significant quantities in the concrete walls of newly built residential buildings (about 15,000 m(2) of apartments), and to propose appropriate technical solution for PAH removal in this case. As PAH occurrence, determination and remediation in concrete is, to our knowledge, a completely new field, it was necessary to face a number of challenges, including lack of regulations considering contents of PAHs in concrete, investigation of the origin of PAH contamination in concrete (if established), as Well as finding feasible and non-expensive remediation method, which would be appropriate for residential space. In first part of this study, a Markedly high concentrations of 5 PAHs were detected by UPLC/PDA analysis in samples of both concrete walls and mineral oil used for coating of planks during formwork, while control concrete and mineral oil, taken from independent construction site, were taken as a reference. Such coincidence, as well as the fact that mineral oil has penetrated into the concrete which is proven by ASAP/MS analysis, pointed to the mineral oil as the most probable source of PAH contamination of the concrete. In the second part, an efficient and easy-applicable method for PAH oxidation in concrete (called FHO3AOP), using UV light, H2O2 and ozone, was presented and discussed in terms of previous literature data.

AB  - Polycyclic aromatic hydrocarbons (PAH) have been listed by the United States Environmental Protection Agency (US EPA) and by the European Community as priority environmental pollutants. The removal of PAHs from soils, sediments and waste water has attracted attention of scientists and engineers for several decades. Electrochemical oxidation of PAH compounds in water, is receiving increasing attention, due to its convenience and simplicity. In this study we performed electrochemical oxidation of 16 EPA PAHs mixture in 10% NaCI aqueous solution in potentiostatic conditions, at voltage 1 V. Decrease of concentration of some individual PAHs, up to 70% referred to their starting concentration, after 60 min of electrolysis, was confirmed by UPLC/PDA analysis. In further work investigation was extrapolated to in situ removal of PAHs from concrete, as the medium where, to our knowledge, such way of PAH removal has not been investigated before. High concentrations of PAH contamination occurred in the concrete structure of the residential buildings in Belgrade in 2014. Application of DC voltage of 50 V between nickel and stainless steel electrodes packed in the concrete wall, moisturized with the 10% NaCI solution, led to considerable removal of the pollutants by oxidation process throughout the concrete.

AB  - This manuscript presents contribution on the improved efficiency of the alkaline electrolytic production of hydrogen by in situ adding activating compounds directly into the electrolyte during the electrolytic process. New electrode material, ternary system, Ni-Cu-Mo, was applied as activating compound i.e. ionic activator. The energy requirements per mass unit of hydrogen produced is reduced for more than 10%, compared to non-activated, 30 wt. % KOH electrolyte system. Energy saving is higher at higher temperatures and at higher current densities. During the electrolytic process, the ionic activators develop nanosized porous structure deposits on the surface of the Ni electrode. Presented results point out a strong possibility of the usage of ternary ionic activators in industrial applications. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

AB  - This paper presents investigations on the influence of in-situ ionic activation using combination of three D-metals: Ni, Co and Moon the hydrogen evolution reaction (HER) mechanism and kinetics. Polarization measurements were performed to obtain kinetic parameters for the HER and the results are presented to show Tafel slopes, exchange current densities and apparent energy of activation. The values of the kinetic parameters confirm the existence of two Tafel slopes, in the case of NiCoMo based ionic activators (i.a.) in the investigated temperature range, with very high values of the exchange current density. Electrochemical impedance spectroscopy measurements were employed to further investigate the origin of the obtained electrocatalytic effect on the HER. The measurements were performed at several overpotentials and temperatures. It was found that co-deposition of Ni, Co and Mo species on the Ni cathode results in a large number of active sites for hydrogen adsorption, and a synergetic effect giving electronic structure suitable for the HER, are the main factors contributing to the enhanced HER kinetics. It was shown that EIS measurements had a crucial role in determining the HER mechanism, especially with the complex in-situ activation of the alkaline electrolysis.

AB  - The electrochemical behavior of cobalt ethylenediamine complexes (Co(en)), at pH 12 was investigated by cyclic voltammetry (CV), the potentiostatic pulse technique and polarization curve measurements at stationary and rotating glassy carbon (GC) electrodes. It was shown that sixteen different species could be formed in a solution containing Co(en)3, with the most stable one at all pH values being [Co(en)(3)](3+). The reduction of [Co(en)(3)](3+) into [Co(en)(3)](2+) was shown to be a totally irreversible, one-electron exchange reaction. Further reduction of [Co(en)(3)](2+) was found to be a complex process leading to cobalt deposition at potentials more negative than -1.45 V vs. SCE. The process of [Co(en)(3)](2+) oxidation was also complex and most probably coupled with chemical reactions.

AB  - Catalyst based on cobalt and chrome was investigated as cathode material for hydrogen production process via water electrolysis. Electrocatalytic efficiency of proposed system was studied using quasi-potentiostatic, galvanostatic and impedance spectroscopy techniques of the catalyst obtained by in situ electrodeposition in an alkaline, 6 M KOH, electrolyser. In accordance to our previous studies, synergetic effect of cobalt complex and chrome salt is observed, with its maximum at high temperatures and for high current densities (industrial conditions). The Tafel slopes were found to be around 120 mV and exchange current densities in the range of 10(-3) mA cm(-2) up to 10(-2) mA cm(-2). Results are presented to show the Tafel slopes, the exchange current densities, the apparent energy of activation and the apparent electrochemical surface of in situ formed Co-Cr catalyst. This study shows that catalytic performance of Co-Cr was achieved not only from the increase of the real surface area of electrodes, but also from the true catalytic effect.

AB  - In this study, different Ni-W coatings, obtained by cheap and technologically simple electrodeposition method, were examined as potential electrocatalysts for the hydrogen evolution reaction (HER). All electrodepositions were done on a Ni mesh substrate from ammoniacal-citrate bath containing different concentrations of Na2WO4. The influence of deposition parameters, such as deposition current density, pH and composition of ammoniacal-citrate bath on electrocatalytic activity of obtained Ni-W coatings toward HER was examined by polarization curve measurements in 6 M KOH at room temperature. The morphology and tungsten content of the Ni-W coatings were investigated by means of SEM and EDS analysis. All investigated electrodes have shown high electrocatalytic activity for the HER. The samples obtained at higher deposition current densities had the lowest overvoltage for the HER. It has been shown that the plating bath pH value is very important parameter in obtaining active coatings. Results of the analysis of polarization curves, morphology of deposited Ni-W coatings and the content of tungsten in the coatings, indicate that the surface roughness of the coatings is responsible for their catalytic activity towards HER.

AB  - In this manuscript we have presented the results of the use of ternary ionic activator in the alkaline water electrolysis. Novel Ni-Co-Mo based ionic activator was added in-situ to standard electrolyte. Energy consumption of the alkaline electrolyzer was determined at different current densities and elevated temperatures. Energy saving was higher at higher temperatures and higher operating current densities. Results showed that the reduction in energy consumption using Ni-Co-Mo based ionic activator was about 17%, compared to standard 6 M KOH. SEM morphology investigation proved the deposition of nickel, cobalt and molybdenum species on the cathode, greatly increasing the active surface area. UV/VIS spectroscopy was used to monitor changes in the electrolyte composition during the electrolytic process, and results show the decrease in the ionic activator concentration in the 6 M KOH. Our experiments point out a strong possibility of the usage of these ternary ionic activators in industrial alkaline electrolyzers. Copyright (C) 2013, Hydrogen Energy Publications, LLC.

abstract = "In this manuscript we have presented the results of the use of ternary ionic activator in the alkaline water electrolysis. Novel Ni-Co-Mo based ionic activator was added in-situ to standard electrolyte. Energy consumption of the alkaline electrolyzer was determined at different current densities and elevated temperatures. Energy saving was higher at higher temperatures and higher operating current densities. Results showed that the reduction in energy consumption using Ni-Co-Mo based ionic activator was about 17%, compared to standard 6 M KOH. SEM morphology investigation proved the deposition of nickel, cobalt and molybdenum species on the cathode, greatly increasing the active surface area. UV/VIS spectroscopy was used to monitor changes in the electrolyte composition during the electrolytic process, and results show the decrease in the ionic activator concentration in the 6 M KOH. Our experiments point out a strong possibility of the usage of these ternary ionic activators in industrial alkaline electrolyzers. Copyright (C) 2013, Hydrogen Energy Publications, LLC.

AB  - The kinetic of non-isothermal dehydration of equilibrium swollen poly(acrylic acid-co-methacrylic acid) hydrogel (PAM) has been investigated. Thermogravimetric and conversion dehydration curves were recorded at various heating rates 5-30 K min(-1). The conversion dehydration curves at all investigated temperatures can be mathematically described using the logistic regression function in entire. It was found that activation energy complexly changes with the increasing dehydration degree. Physical meaning of the parameters of logistic function (band w) is given. It was established that, during the dehydration, changes in the fluctuating hydrogel structure occur, and that limiting step on the kinetics of hydrogel dehydration have rate of structural rearrangement of hydrogel (actual relaxation mechanism). A procedure for determining the dependence of effective activation energy on temperature and dehydration degree, based on logistic function, is exposed.

AB  - Hydrogen is considered to be the most promising candidate as a future energy carrier. One of the most used technologies for the electrolytic hydrogen production is alkaline water electrolysis. However, due to high energy requirements of about 4.5-5 kWh/Nm(3) H(2) in most industrial electrolysers, the cost of hydrogen produced in such a way is high. There are various attempts to overcome this problem, like zero-gap cell geometry, development of new diaphragm materials, development of new electrocatalytic materials for electrodes, etc. In continuous search to improve this process using advanced electrocatalytic materials for the hydrogen evolution reaction (HER), based on transition metal series, catalyst based of cobalt and wolfram was investigated as cathode material. On the basis of the results of our experiments, there is a strong indication that the Co-W catalyst reduces energy needs per mass unit of hydrogen produced for more than 20% in some cases. Objective of this work was to investigate the electrocatalytic efficiency using quasi-potentiostatic, galvanostatic and impedance spectroscopy techniques. Results are presented to show the Tafel slopes, the exchange current densities, the apparent energy of activation, the apparent electrochemical surface and the stability of Co-W catalyst. Results suggest to significant catalytic performance not only from the increase of the real surface area of electrodes, but also from the true catalytic effect of the Co-W catalyst.

AB  - Hydrogen production via electrolysis of water from alkaline aqueous electrolytes is a well-established conventional technology. However, the cost of hydrogen produced in such a way is high. To improve this process we have investigated in situ activation with Ni-Mo electrocatalytic material for electrodes. This two d-metal combination possesses one of the highest known activities for the HER. Ni-Mo based catalyst was not applied at industrial applications yet, because under industrial conditions (high temperature and concentrated alkaline solution), permanent destruction of the Ni-Mo alloy coating occurs. The most important result of this study is that the Ni-Mo deposit obtained by in situ activation, under industrial conditions, exhibit long term stability and the electrodes retain their high catalytic performance. The process of adding Ni-Mo activating compounds in situ exhibits savings of the energy consumption that can go beyond 20% in some cases. Copyright (C) 2011, Hydrogen Energy Publications, LLC.

AB  - Hydrogen is considered to be the most promising candidate as a future energy carrier. One of the most used technologies for the electrolytic hydrogen production is alkaline water electrolysis. Electrode materials used in alkaline water electrolysis are mainly made from Ni or Ni-based alloys due to their desirable mechanical and chemical stability in hot and alkaline solution. Considerable research effort has been conducted on enhancement of electrocatalytic activity of Ni electrodes. Electrocatalytic activity of Ni electrode for the hydrogen evolution reaction (HER) in alkaline solution was compared to the electrode made from electrodeposition of Co and Co-V species on Ni support electrode using ac and dc electrochemical techniques. Analysis of Tafel polarization curves for the HER in alkaline solution reveals an increased electrocatalytic activity of the electrodeposited electrodes if compared to the Ni, This was additionally proved by measuring energy input (overpotential) for the given hydrogen production (fixed current density) and vice versa. Electrochemical impedance spectroscopy was applied in order to investigate the obtained effect of electrodeposited electrodes. It was found that the apparent electrochemical surface of investigated electrodes was significantly increased by the process of electrodeposition.

AB  - We have investigated the possibility of developing high-performance, cost-effective and durable non-noble Co metal electrocatalyst for PEMFC. In this work we applied electrodeposition process for PEMFC electrode preparation that is very efficient and far simpler than any other investigated method. The fuel cell with electrodeposited Co as anode catalyst has shown satisfying performance level. In determining FCs operating conditions, subsequent electrochemical impedance and output power measurements were done, which enable the insight into the Co catalyst based anode behavior. Structure analysis of the electrodeposited anode layer was done by means of SEM and EDS technique. Although the Pt catalyst has higher efficiency, its cost performance ratio is significantly lower than for the Co catalyst, thus this investigation gives interesting possibilities in area of stationary fuel cell application.

AB  - An electrochemical H/D separation system consisting of electrolyzer and PEM fuel cell has been proposed. Isotope separation could be important as a part of the energy saving process in an energy-hydrogen-energy cycle. Any transfer of energy into hydrogen or vice versa induces change of the H/D isotope ratio, which can be considered, as a method to produce heavy water as by-product. In this way, the separation efficiency can contribute to the overall efficiency of the cycle. (c) 2008 Elsevier B.V. All rights reserved.
