AB  - In this paper, we have systematically studied the structural, morphological, and optical properties of Ni-doped TiO2, synthesized via a simple, cost-effective electrospinning method followed by calcination at 500 C. The nanofibers with a core-shell structure were relatively homogeneous, smooth and randomly oriented, and there were no significant differences in fiber diameters due to Ni2+ content. Core loss mapping using electron energy loss spectroscopy confirmed an even distribution of titanium and relatively uniform nickel in the fibers. It was found that doping with 0.5 mol.% Ni2+ decreased the rutile content, while doping with 1 mol.% Ni2+ resulted in a pure anatase phase with a significantly increased specific surface area (36.6 m2/g). Further increase in Ni2+ content (3-10 mol.%) not only prolonged the response of TiO2 nanofibers to visible light, but also increased the specific surface area (49.5 m2/g), decreased crystallite size (7 nm), and increased rutile content in TiO2 (33 wt.%). Photoluminescence analysis revealed that doping TiO2 with different amounts of Ni2+ leads to a gradual decrease of emission spectra intensity and red shift in the maxima positions. The XPS results confirmed that as the Ni2+ content enlarged, the Ti2+ and Ti3+ content increased significantly, effectively promoting the formation of oxygen vacancies. Raman analysis showed that an increase in nickel content (3-5 mol.%) led to a decrease and shift in peak intensity due to Ti3+ formation and also the possible presence of NiTiO3 phases. HRTEM analysis showed that Ni was doped into the substitution sites of both the anatase and rutile TiO2 lattice but had a stronger influence on the distortion of the anatase phase. The photocatalytic activity of Ni-doped TiO2 nanofibers was explored by analyzing the degradation of an antibiotic, oxytetracycline, monitored in laboratory conditions under visible light irradiation. After 60 minutes of irradiation, the degradation  of OTC with 1Ni-TiO2 reached 76.4% and with 10Ni-TiO2 70.5%.

AB  - The aim of this research was to prove the function of the putative opine dehydrogenase from Desulfohalobium retbaense and to characterize the enzyme in terms of functional and kinetic parameters. A putative opine dehydrogenase was identified from a metagenomic library by a sequence-based technique search of the metagenomic library, and afterward was successfully heterologously produced in Escherichia coli. In order to examine its potential for applications in the synthesis of secondary amines, first the substrate specificity of the enzyme towards different amino donors and amino acceptors was determined. The highest affinity was observed towards small amino acids, preferentially L-alanine, and when it comes to α-keto acids, pyruvate proved to be a preferential amino acceptor. The highest activity was observed at pH 6.5 in the absence of salts. The enzyme showed remarkable stability in a wide range of experimental conditions, such as broad pH stability (from 6.0–11.0 after 30 min incubation in buffers at a certain pH), stability in the presence of NaCl up to 3.0 M for 24 h, it retained 80% of the initial activity after 1 h incubation at 45°C, and 65% of the initial activity after 24 h incubation in 30% dimethyl sulfoxide.

AB  - Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified
with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C),
and examined for the ethanol oxidation reaction (EOR) in alkaline solution. The catalysts were characterized by
energy-dispersive X-ray spectroscopy, X-ray diffraction, transmission electron microscopy and X-ray photoelectron
spectroscopy, as well as cyclic voltammetry. As reference catalysts, Pd/C and Pt/C were used. The electrochemically
active surface area of all samples was determined from COads and Cuupd desorption and Pd oxide
reduction, and used to assess their intrinsic activity for EOR. Intimate contact of Pd with Cu atoms enhanced its
activity, regardless of the type of bimetal catalyst. The atomic Pd:Cu ratio between 2:1 and 4:1 appears to be
optimal for high activity. The most active catalyst under the potentiodynamic conditions was Cu@Pd/C with
θ(Cu) = 0.21,although Pd-Cu/C was superior during the potentiostatic test. All bimetallic catalysts surpassed
Pd/C in mass activity. The EOR activity of Pt/C was higher compared to Pd-based catalysts at low potentials,
both in terms of specific and mass activity, but with a significant decline over a 30-min potentiostatic stability
test.

AB  - In this paper, 12-tungstenphosphoric acid (PWA) was synthesized in
combination with FeCl3 at room temperature (25 °C). At such manner, Fe3+ ion
exchange gave new 12-tungstenphosphoric salt of the transition metal iron
(FePW12O40×nH2O; Fe-PWA). Thermal analysis determined the temperature of
about 596 °C of the phase transition, i.e., the temperature at which the structure of
the Kegin anion is disturbed. Therefore, it was chosen temperature above the
breakdown of the Kegin anion of 650 °C, and which is required to obtain phosphate
tungsten bronzes (PWB) doped with iron (Fe-PWB). The sample was kept in the
oven for 10 min. Such obtained new Fe-PWB doped bronze was further investigated
by the X-ray powder diffraction (XRPD) and Rietveld methods. The XRPD patterns
of Fe-PWA and Fe-PWB were taken in the 3–90° 2θ angle range, and clearly reveal
crystallographic and structural differences between these two phases. Determined
unit-cell parameters of Fe-PWB obtained by the Rietveld method in the monoclinic
crystallographic system are as following: a0 = 7.53(2) Å; b0 = 7.51(1) Å; c0 =
7.64(1) Å; β0 = 89.7(2)° and V0 = 431(2) Å3. These unit-cell parameters were
compared with PWB, as well as other previously characterized doped bronzes (LiPWB and Ca-PWB). It can be concluded that inserting of the Fe3+ ion into the
PWB’s structure was undoubtedly proven, and have the most influence to the axis a0
(i.e. it significantly increased), angle β0 (i.e., it significantly decreased), and volume
V0 (i.e., it significantly increased). On the other hand, influence to the axis c0 is quite
smaller (i.e. it slightly decreased), whereas influence to the axis b0 is minor. Such
behavior is also very different in comparison to the Li-PWB and Ca-PWB.

AB  - Due to Li-ion batteries having become the main power source of most portable
electronic devices, their waste has also become a significant environmental problem.
To find batteries that would be environmentally friendly, this work examines Zn-ion
batteries in an aqueous solution of ZnCl2. The ZnMnO4 was synthesized by glycine
nitrate combustion of Zn(NO3)2, Mn(NO3)2 and glycine as a chelating agent [1]. The
structure of the material obtained was characterized by X-ray powder diffraction
(XRPD) showing a spinel structure; the morphology was characterized by scanning
electron microscopy (SEM) showing that nano-particles were obtained. The
electrochemical characterization was done by cyclic voltammetry in an aqueous
solution of ZnCl2. The mixture pasted on the glossy carbon electrode was prepared
by mixing the cathode material, graphite and polyvinyl diene difluoride (PVDF) in a
ratio 85:10:5 [2]. Due to the low discharge capacity obtained of ~14 mAh g-1 for 5
mV s-1, further examination was done by adding 1 ml of 1M Mn(NO3)2 into 10ml of
a saturated aqueous solution of ZnCl2. After adding the Mn(NO3)2 , the discharge
capacity increased from ~14 mAh g-1 to ~65 mAh g-1 at the same polarization rate,
making this additive a promising one for aqueous Zn-ion batteries. Further
investigation needs to be directed to adding the same additive in larger amounts
compared to 1ml to the same volume of the electrolyte. The results obtained suggest
the aqueous Zn-ion battery described in this work to be a potentially promising
“green” battery that may replace harmful commercial organic Li-ion batteries.

AB  - To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and microemulsion method, and sintered at 1150°C and 1300°C. The phase composition and morphology of as-prepared powders as well as sintered ceramics were thoroughly examined by X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS). The dielectric and ferroelectric measurements were performed in detail. Generally, the samples sintered at 1300°C had better performances than those sintered at 1150°C. The composite synthesized by thermal decomposition and sintered at 1300 °C stands out among other prepared BaTiO3/CoFe2O4 ceramics, owing to high stability in the wide frequency range and low leakage currents. The obtained results indicate that such composite might be successfully applied as a functional multiferroic.

As-prepared powders were additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the detailed examination of phase composition and morphology. The magnetic, dielectric, and ferroelectric properties were investigated. The optimal phase composition in the BaTiO3/NiFe2O4 composite, sintered at 1150 °C, resulted in a wide frequency range stability. Additionally, particular phase composition indicates favorable properties such as low conductivity and ideal-like hysteresis loop behavior. The favorable properties of BaTiO3/NiFe2O4 make this particular composite an ideal material choice for further studies on applications of multi-ferroic devices.

AB  - Opine dehydrogenases are a family of NAD(P)H dependent oxidoreductases, which
catalyze the reductive condensation of an α amino group from an amino acid with an αketo acid during anaerobic glycolysis by regenerating NAD. They are widespread in
cephalopods and mollusks. Opines are associated with crown gall tumor pathogenesis
caused by A. tumefaciens providing nutrients to the pathogen, and novel opine compounds
acting as metallophores have been identified. Besides, opine-type secondary amine
dicarboxylic acids are chiral intermediates of angiotensin-converting enzyme inhibitors. A
novel enzyme originating from an extremophile bacterium, with assumed opine
dehydrogenase function was successfully expressed in Escherichia coli STAR cells and
purified by affinity chromatography. Molecular mass determined by SDS-PAGE was
approximately 40 kDa. The activity was measured by using pyruvate and alanine as
substrates, by which proved that it has opine dehydrogenase activity.

AB  - The aim of this research was to improve the operational stability and enable the reusability of ω-transaminase for synthesis of new enantiopure chiral amines of steroids. Dihydrotestosterone was used to optimize the synthetic procedure of corresponding amino-steroid on a larger scale. The obtained product 3α-amino-5α-androstan-17β-ol was isolated and characterized. The enzyme was immobilized on a methacrylate-based carrier, giving the specific activity of 1.84 U/g of dry polymer. Higher residual activity of the immobilized enzyme in comparison to the soluble form (100 % versus 35%) after 24 h incubation in 35 % dimethylformamide (DMF) was obtained. The soluble enzyme retained 19 % of the initial activity after 2 h incubation in 35 % DMF at 70 °C, while the activity of the immobilized enzyme decreased only to 75 %. Immobilized retained 85 % of initial activity after ten consecutive cycles of 3α-amino-5α-androstan-17β-ol synthesis. We have tested the specificity of the ArRMut11 variant, further increased its stability by immobilization, and used it in several cycles for the synthesis of 3α-amino-5α-androstan-17β-ol. We showed that the enzyme previously evolved for higher stability as the immobilized variant showed more increased stability and high reusability that can more effectively be applied for the biosynthesis of amino steroids.

AB  - Recently, two different effects of phosphate tungsten (PWB) and phosphate
molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory
Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble in
BR solution [2], the addition of different masses of PWB linearly decreases the BR
oscillation time, while the addition of different masses of PMoB had no effects on
the BR reaction. Furthermore, PWB has an identical role as metal catalyst Mn2+ in
BR reaction and for obtained behavior is probably responsible the different
mechanisms of heterogeneous catalysis of these bronzes in oscillatory reaction.
Therefore, a deeper investigation was done in order to find the major structural
characteristic of these two bronzes by using the XRPD method.
What is so different for these two bronzes, causing dissimilar effects in BR
reaction, is it “just” catalytic activity of central cation or there is something more?
The XRPD method confirmed very different structures of PWB and PMoB as
monoclinic and orthorhombic, respectively [3,4]. This work tries to connect the
structural properties of PWB and PMoB with BR oscillatory reaction responses,
expanding the usage of oscillatory reaction in material science and catalysis, in
general.

AB  - Indigo carmine (InC) is broadly used blue dye in different industrial area. This work aims to
obtain analytical curves for determination of InC in aqueous solutions. For such as purposes, two
methods were used: UV/VIS spectrophotometry and the kinetic method based on Briggs-
Rauscher (BR) oscillatory reaction, and compared in terms of methods sensitivity which
expressed as limit of detection (LOD) and limit of quantification (LOQ). To the best authors' knowledge, as candidate for proposed analytical method, the BR oscillatory reaction was applied
for the first time to InC quantification. The results obtained show that kinetic method using BR
oscillatory reaction has a quite lower LOD and LOQ making this method more acceptable to
determine an unknown concentration of InC dissolved in water, compared to UV/Vis
spectrophotometric method.

expressed as limit of detection (LOD) and limit of quantification (LOQ). To the best authors' knowledge, as candidate for proposed analytical method, the BR oscillatory reaction was applied
for the first time to InC quantification. The results obtained show that kinetic method using BR
oscillatory reaction has a quite lower LOD and LOQ making this method more acceptable to
determine an unknown concentration of InC dissolved in water, compared to UV/Vis
spectrophotometric method.",

AB  - Indigo carmine is a commonly used industrial blue dye. To determine its concentration in a
commercially available food dye composed of a mixture of indigo carmine and D-glucose, this paper
characterizes it through (ATR, KBr) FTIR micro-Raman as well as UV/Vis and clock: Briggs–Rauscher
(BR) oscillatory reaction methods. The indigo carmine was detected in the bulk food dye only by
applying micro-Raman spectroscopy, indicating a low percentage of the indigo carmine present.
This research provides an improvement in the deviations from the experimental Raman spectrum as
calculated by the B97D/cc-pVTZ level of theory one, resulting in a better geometrical optimization of
the indigo carmine molecule compared to data within the literature. The analytical curves used to
determine indigo carmine concentrations (and quantities) in an aqueous solution of food dye were
applied by means of UV/Vis and BR methods. BR yielded significantly better analytical parameters:
100 times lower LOD and LOQ compared to commonly used UV/Vis. The remarkable sensitivity
of the BR reaction towards indigo carmine suggests that not only does indigo carmine react in an
oscillatory reaction but also its decomposition products, meaning that the multiple oxidation reactions
have an important role in the BR’s indigo carmine mechanism. The novelty of this research is the
investigation of indigo carmine using a clock BR reaction, opening new possibilities to determine
indigo carmine in other complex samples (pharmaceutical, food, etc.).

Using the DPPH test, all derivatives showed good antioxidant activity, better than ascorbic acid, and the 2-tert- -butyl-5-(propylthio)-1,4-benzoquinone derivative showed the strongest effect. Better antibacterial potential was observed against Gram-positive bacteria in the broth microdilution method in which the 2-tert-butyl-5-(phenylthio)-1,4- -benzoquinone derivative showed the strongest activity (MIC = 15.6 μM). The results of toxicity tests, using the Brine shrimp test, indicated that the derivatives lose their toxic potential compared to TBQ, except for 2-tert-butyl-6- -(phenylthio)-1,4-benzoquinone, which showed a 3 times stronger effect. Cytotoxicity was assessed by the MTT assay in 24 and 72 h treatments in MRC-5, HS 294T and A549 cell lines in threefold decreasing gradient (11, 33 and 100 μM). Modifications potentiate the cytotoxic effect, and the strongest effect was observed with the 2-tert-butyl-5,6-(ethylendithio)-1,4-benzoquinone derivative. In addition, the genotoxic potential was examined in the MRC-5 cell line using the comet assay. All tested derivatives of TBQ showed a genotoxic effect at all applied subtoxic concentrations. In general, the chemical modifications of TBQ enhanced its biological activity.

AB  - Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 degrees C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N-2 physisorption at 77 K enabled determination of the BET specific surface area as 25.3 m(2)/g and (BJH) mesopore volume as 21.5 m(2)/g. The material constant (B) of the nanocrystalline nickel manganite fibers applied by drop-casting on test interdigitated electrodes on alumina substrate, dried at room temperature, was determined as 4379 K in the 20-50 degrees C temperature range and a temperature sensitivity of -4.95%/K at room temperature (25 degrees C). The change of impedance with relative humidity was monitored at 25 and 50 degrees C for a relative humidity (RH) change of 40 to 90% in the 42 Hz pi 1 MHz frequency range. At 100 Hz and 25 degrees C, the sensitivity of 327.36 +/- 80.12 k omega/%RH was determined, showing that nickel manganite obtained by electrospinning has potential as a multifunctional material for combined humidity and temperature sensing.

AB  - This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films were obtained from emulsions and dispersions by casting method. Coatings were formed by the application of emulsions on existing packaging. Synthesis of emulsions and dispersions were performed by combining biopolymers (chitosan-gelatin, pectin-gelatin) with lemongrass essential oil (LEO), Zn(CH3COO)2.2H2O, or ZnO, as active components. Fourier transform infrared (FTIR) spectra of the films showed that the addition of glycerol contributed to the forming of strong hydrogen bonds between glycerol and chitosan-gelatin or pectin-gelatin composites, facilitating the process of polymer branching, which is substantial for encapsulation. Thermal analyses revealed two characteristic processes occurring at 110 degrees C (water evaporation) and within 215-235 degrees C (degradation of polysaccharide and glycerol). Major weight losses were observed at 290 degrees C (chitosan-gelatin films) and 215 degrees C (pectin-gelatin films). The chitosan-gelatin films exhibited a lower degree of solubility (31-21%), and better mechanical properties comparing with the pectin-gelatin films. The chitosan-gelatin emulsions and dispersions exhibited a higher antibacterial effect in vitro against E. coli, B. subtilis, and S. aureus. In the case of the pectin-gelatin emulsions, the impact of LEO on the antibacterial activity was evident. The effects of biopolymer coatings on the development of microorganisms on fresh raspberries (Rubus idaeus L.) were performed in vivo during eight days of raspberry storage at refrigerator temperature. The tested coatings extended the shelf life of stored raspberries from four to eight days. The synergistic effect between LEO and ZnO or Zn-Ac was observed both in vivo and in vitro.

AB  - Pt, PtSn and PtSnO2 catalysts supported on high surface area carbon synthesized by microwave assisted polyol procedure were tested for methanol oxidation. Based on TGA, EDX and XRD analysis, PtSn/C is composed of Pt and Pt3Sn phase while the rest of Sn is present in a form of very small tin oxide particles. This paper focuses on structure-activity relationships for CO tolerance and methanol oxidation reactions after addition of Sn to Pt catalysts. Alloying of Sn with Pt improves the rate of CO oxidation despite the fact that the pure Sn does not react with CO and therefore activity for methanol oxidation increases similar to 2 times in comparison to Pt/C catalyst. PtSn/C catalyst shows small advantage in comparison with PtSnO2/C catalyst due to the alloyed Sn and its electronic effect. Long term stability tests also confirmed that PtSn/C catalyst is somewhat better in comparison to PtSnO2/C.

AB  - Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides an examination of a potential replacement for commercial cathode material using a naturally occurring purpurin in aqueous solutions of lithium and sodium salts. The purpurin is extracted from the Madder plant (Rubia tinctorum) and characterized through XRPD, FTIR, and SEM methods. The intercalation and de-intercalation capacities obtained for the purpurin as a cathode material in the aqueous solution of LiNO3 are approximately 40 mAh g(-1). Compared to the capacity of similar to 35 mAh g(-1) obtained for commercially used transition metal oxides in an aqueous solution of Li salt, results presented make the purpurin a promising material for the "green" development of Li-ion batteries. Although the initial purpurin capacity in NaNO3 solution is almost doubled (similar to 73 mA h g(-1)) compared to that of Li-salt, it is unstable and fades during cycling. The possible explanation of the electrochemical behavior of purpurin as the cathode material in aqueous solutions of Li and Na salts is discussed in detail.

AB  - Cerium oxide nanoparticles (nCeO(2)) have widespread applications, but they can be hazardous to the environment. Some reports indicate the toxic effect of nCeO(2) on tested animals, but literature data are mainly contradictory. Coating of nCeO(2) can improve their suspension stability and change their interaction with the environment, which can consequently decrease their toxic effects. Herein, the exopolysaccharides levan and pullulan, due to their high water solubility, biocompatibility, and ability to form film, were used to coat nCeO(2). Additionally, the monosaccharide glucose was used, since it is a common material for nanoparticle coating. This is the first study investigating the impact of carbohydrate-coated nCeO(2) in comparison to uncoated nCeO(2) using different model organisms. The aim of this study was to test the acute toxicity of carbohydrate-coated nCeO(2) on the bacterium Vibrio fischeri NRRL B-11177, the crustacean Daphnia magna, and zebrafish Danio rerio. The second aim was to investigate the effects of nCeO(2) on respiration in Daphnia magna which was performed for the first time. Finally, it was important to see the relation between Ce bioaccumulation in Daphnia magna and Danio rerio and other investigated parameters. Our results revealed that the coating decreased the toxicity of nCeO(2) on Vibrio fischeri. The coating of nCeO(2) did not affect the nanoparticles' accumulation/adsorption or mortality in Daphnia magna or Danio rerio. Monitoring of respiration in Daphnia magna revealed changes in CO2 production after exposure to coated nCeO(2), while the crustacean's O-2 consumption was not affected by any of the coated nCeO(2). In summary, this study revealed that, at 200 mg L-1 uncoated and carbohydrate-coated nCeO(2) are not toxic for the tested organisms, however, the CO2 production in Daphnia magna is different when they are treated with coated and uncoated nCeO(2). The highest production was in glucose and levan-coated nCeO(2) according to their highest suspension stability. Daphnia magna (D. magna), Danio rerio (D. rerio), Vibrio fischeri (V. fischeri)

AB  - Functionalization of electrodes is a wide-used strategy in various applications ranging from single-molecule sensing and protein sequencing, to ion trapping, to desalination. We demonstrate, employing non-equilibrium Green ' s function formalism combined with density functional theory, that single-species (N, H, S, Cl, F) termination of graphene nanogap electrodes results in a strong in-gap electrostatic field, induced by species-dependent dipoles formed at the electrode ends. Consequently, the field increases or decreases electronic transport through a molecule (benzene) placed in the nanogap by shifting molecular levels by almost 2 eV in respect to the electrode Fermi level via a field effect akin to the one used for field-effect transistors. We also observed the local gating in graphene nanopores terminated with different single-species atoms. Nitrogen-terminated nanogaps (NtNGs) and nanopores (NtNPs) show the strongest effect. The in-gap potential can be transformed from a plateau-like to a saddle-like shape by tailoring NtNG and NtNP size and termination type. In particular, the saddle-like potential is applicable in single-ion trapping and desalination devices.

AB  - The aim of this research was to verify the authenticity of monofloral honeys from the territory of the Republic of Serbia on the basis of physicochemical parameters routinely measured in honey quality control using multivariate analysis. Seventeen samples of monofloral honey (11 samples of acacia honey and 6 samples of sunflower honey) from the territory of the Republic of Serbia were analyzed. Physicochemical analysis of the samples included the examination of basic quality parameters and qualitative and quantitative analyses of phenolic compounds. In the samples tested, a total of 93 phenolic compounds were tentatively identified, and 19 of them were quantified. The obtained physicochemical analysis of the data served as input for the multivariate analysis. The h..t map, which is useful for visualizing numerical data, was used for this purpose. The obtained results showed that the applied data can serve to clearly separate acacia and sunflower honeys.

AB  - Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been investigated. Morphological and structural characteristics of this electrode type obtained by various parameters of RC regimes were examined by the techniques of scanning electron and optical microscopies, while the amount of hydrogen produced during electrodeposition process was quantified by determination of the average current efficiency for hydrogen evolution reaction. To optimize the process of formation of the honeycomb-like electrodes, the following parameters of square wave RC regimes were analyzed: the cathodic current density, the same anodic to cathodic time ratios but various durations of the cathodic and the anodic pulses, and the various values of the anodic to cathodic time ratios. The minimal amount of hydrogen spent for formation of the honeycomb-like electrodes with maximal number of holes formed from detached hydrogen bubbles is obtained with the anodic to cathodic time ratio of 0.50 and duration of the cathodic and anodic pulses of 2 and 1 s, respectively. To explain formation of the honeycomb-like electrodes of optimal morphological and structural characteristics, the upgraded mathematical model defining the RC regime in the second range was proposed and discussed.
