AB  - Praćenje pojave i brzine korozije, nastanak termičkih oksida na površini metalnih delova eletroenergetskog postrojenјa, kao i način njihovog otklanjanja na način koji je tehnološki pogodan, ekonomski pristupačan i ekološki opravdan prikazan je u ovom tehničkom rešenju Ispitivanjem je ustanovljeno da su metalni delovi na kojima se javlja korozija izrađeni od na nerđajućeg čelika AISI 304, pa je pojava korozije i termičkih oksida praćena je u odnosu na to, kao i sastav prašine sa kojom su metalni delovi u kontaktu. Pojava termičkih oksida na površini nerđajućih čelika posledica je povišene temperature na mestu zavarivanja metalnih delova.
Merena je vrednost pH oba rastvora: etalonskog i zasićenog rastvoru prašine iz pogona.
Sastav uzoraka prašine određen je FTIR metodom, pa su na osnovu prisutnih jona u rastvoru definisana ostala ispitivanja.
Određivan je korozioni potencijal Ekor, vrednost otpora polarizacije Rp, kao i gustina struje korozije jkor. Sva ispitivanja nerđajućeg čelika u etalonskom rastvoru i u zasićenom rastvoru prašine iz pogona firme naručioca, rađena su za 1 sat i u toku 25 dana.
Kao rezultat svih istražoivanja, date su tehnološke preporuke i način otklanjanja korozije i termičkih oksida.

AB  - Monitoring the occurrence and rate of corrosion, the formation of thermal oxides on the surface of metal parts of the power plant, as well as the method of their elimination in a way that is technologically suitable, economically affordable and environmentally justified is shown in this technical solution. It has been established that the metal elements affected by corrosion were made from stainless steel AISI 304. Accordingly, the occurrence of corrosion and thermal oxides was monitored based on the material and the composition of the dust with which the metal parts are in contact. The emergence of thermal oxides on the surface of stainless steels is a consequence of the elevated temperature at the welding site.
The pH value of both solutions was measured: standard and saturated solution of dust from the plant. The composition of the dust samples was determined by FTIR. The other tests were defined based on the ions present in the solution.
The corrosion potential, the value of the polarization resistance, as well as the corrosion current density were determined. All tests of stainless steel in the standard solution and in the saturated solution of dust were performed for one hour within a span of 25 days.
Technological recommendations on how to eliminate corrosion and thermal oxides are provided.
The solution has been applied since January 2021 by ELNOS BL d.o.o.

The discharge capacity of the polypyrrole in the chloride-based electrolyte (for the Zn|PPy cell) is in the range 110 mAh g −1 of PPy, while in the sulfate-based electrolyte ∼150 mAh g −1 of PPy (for the PbSO 4 |PPy and PPy|PbO 2 cells), which is close to the theoretically calculated values. Electrochemical and electrical parameters, reactions in the cells, specific capacity, specific capacitance, energy, and power, for the Zn|PPy, PPy|PbO 2 and PbSO 4 |PPy cells are determined. In addition, the energy efficiency, for the considered systems is estimated.

AB  - Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of α-amylase from Bacillus licheniformis. The formation of a polyaniline layer (PANI) on MAG particles was achieved by chemical polymerization of aniline. Immobilization was carried out by adsorption, as a simple, inexpensive and fast method that allows retention of a large portion of the initial activity of the immobilized enzyme. FTIR spectroscopy was used to characterize the obtained particles and to confirm changes dueto formation of a PANI layer and conjugation of α-amylase on the particle surfaces. Particle size distribution was bimodal and three-modal for MAG and MAG-PANI, respectively. Appearance of a fraction of smaller MAG-PANI particles than MAG particles could be attributed to the formation of PANI particles without the MAG core. Measured values of Zeta potential for MAG-PANI were higher as compared to MAG indicating stabilization of particles in the presence of PANI. Relevant kinetic parameters for immobilized enzyme were determined from the Hanes plot. The apparent Km constant was 1.91 and 1.48 g L–1 for MAG-A and MAG-PANI-A, respectively, while Vm was 0.19 g L–1 min–1 for MAG and 0.32 g L–1 min–1 for MAG-PANI. The obtained values of Km indicated that modification of MAG by PANI enhanced kinetic properties of the immobilized enzyme. Moreover, the modification of MAG by PANI showed the increase in both pH and thermal stabilities of the immobilized enzyme. Studies of the operational activity of the immobilized enzyme on MAG-PANI have shown that 98.8% of starch was hydro-lyzed over 20.0 min. In the first cycle in the packed bed reactor operated in a recycling mode, but approximately five times longer period was required to hyd-rolyze 93.5 of starch in the fifth cycle. In the continuous packed bed reactor without recycling, the degree of starch hydrolysis was not changed significantly during 4 h and was 88.8±1.6%, whereas the half-life of the biocatalyst was 6.2 h. Although coating MAG particles with a polyaniline offers many advantages, the main disadvantage is possible appearance of residues of aniline monomers and dimmers. The potential toxicity of these residues requires precise composition analysis of the product of starch hydrolysis catalyzed by α-amylase adsorbed onto MAG-PANI. © 2018, Association of Chemists and Chemical Engineers of Serbia.

AB  - An environmentally friendly cell using polypyrrole-air regenerative cathode and zinc as anode is investigated in the 3% sodium chloride solution. The cell can operate in different charge and discharge mode. Polypyrrole can be reoxidized (doped) with chloride anions either by using dissolved oxygen or by an external power supply, e.g., small photovoltaic cell. In that way, after discharge, capacity retaining can be achieved by using seawater as the electrolyte. During low discharge rate, the delicate balance between solid state diffusion-controlled dedoping and chemical oxidation of polypyrrole produced by hydrogen peroxide is achieved, generating stable voltage plateau. The cell is proposed to operate as a power supply for different sensor devices in two modes. In the low discharge mode (10–20 mA g−1), it can be used for data acquisition, and at the fast discharge mode (up to 2 A g−1) for collecting data transmission.

AB  - The electrochemical oxidation of the urea in near neutral pH is investigated on platinum electrode. It is shown that oxidation reaction is practically inhibited up to the potentials of ∼0.9 V. The same reaction is investigated onto electrochemically obtained titanium dioxide nanotubes modified by hematite using facile, low-cost successive ion layer adsorption and reaction (SILAR) method. It is shown that such system possesses electrocatalytic activity at very low potentials, and activity can be further improved by the illumination of the electrode in the photo-assisted reaction. The possible application of the photoactive anode is considered in the application of urea based water electrolysis and urea based fuel cell.

Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and m-aminobenzoic acid. The presence of the meta positioned carboxylic group in m-aminobenzoic acid influenced higher co-polymerization potential, different morphology and electrochemical behavior of copolymers compared to polyaniline. Electrochemical activity is achieved by proton exchange in neutral environment that can result in a faster charge/discharge process, which is in the case of PANI limited by slow anion exchange, making this material promising for consideration in super-capacitors and in biological system.

AB  - The immobilization of α-amylase via adsorption on magnetic particles coated with polyaniline was studied. The support was characterized by field emission scanning electron microscopy (FESEM). The obtained magnetic particles were agglomerates of nanoparticles with sizes below 100 nm. The effects of various factors on immobilization, including time, the initial enzyme concentration, pH, and temperature, were examined. The optimum pH, temperature, and time for immobilization were established to be 7, 45°C and 75 min, respectively. The maximum amount of adsorbed α-amylase of 10/100 mg support was determined at the 5 mg/mL enzyme concentration. It appeared that α-amylase was stabilized in terms of pH and temperature by adsorption on magnetic particles coated with polyaniline. The good agreement of the equilibrium data with the Langmuir isotherm model confirmed the monolayer coverage of enzyme molecules on the surface of magnetic particles, and the maximum adsorption capacity was found to be 55.6/100 mg support at 25°C. The biocatalyst retained 55.5 ± 1.63% of its initial activity after nine cycles of reuse in starch hydrolysis at 60°C in a batch reactor. The immobilized enzyme also showed very good storage stability.

AB  - The potential characteristics of graphite felt electrodes, modified by iron oxide, for oxygen reduction are evaluated. Modification is carried out by Successive Ion Layer Adsorption and Reaction (SILAR) method, using a solution of ferric nitrate in methanol for the adsorption of ions, and a solution of sodium hypochlorite for reaction. The reaction activity of the oxygen reduction from the air, in sodium sulfate based solution varying the number of SILAR cycles, as well as the influence of pH is investigated. By comparing the activity with pure platinum, similar activity is obtained at pH = 9.2, as well as good electrode stability. Possible mechanism of the oxygen reduction on the graphite felt modified by iron oxide is discussed.

AB  - Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still represent a base for both theoretical and practical studies. The mentioned properties open up possibilities for practical application in the field of electrochemical systems for energy storage and conversion, sensors, biosensors, antistatic coatings, magnetic shielding, active corrosion protection etc. Bearing in mind that nanostructurization of materials lead to improvement of physical and chemical properties, there is a growing interest in the development of nanosized ICP. Nanosized ICP can be prepared by both chemical and electrochemical procedures. Although chemical synthesis is a common approach, there are also not a few studies of electrochemical synthesis of ICP. The aim of this paper is to review literature dedicated to electrochemical formation of nanostructured ICP with special attention dedicated to polyaniline and polypyrrole as the most popular ICPs.
AB  - Interesovanje za elektroprovodne polimere kako u teorijskom tako i praktičnom smislu utemeljeno je u jedinstvenim svojstvima ovih materijala, kao što su: kontrolisana električna provodljivost, reverzibilna oksidacija redukcija (dopovanje/dedopovanje), optička aktivnost, bio-kompatibilnost, korziona postojanost itd. Ova svojstva otvaraju mogućnosti praktične primene u oblasti elektrohemisjkih primarnih i sekundarnih izvora električne energije, elektrohemijskih kondenzatora, senzorima, biosenzorima, aktivnoj zaštiti od korozije. Imajući u vidu da nanostrukturizacija materijala dovodi do značajnog poboljšanja fizičkih i hemijskih svojstava materijala postoji veliko interesovanje za proučavanje nanostruktuirasnih elektroporvodnih polimera. Nanostruktuirani elektroprovodni polimeri mogu se dobiti hemijskim i elektrohemijskim postupcima sinteze. Iako je hemijska sinteza zastupljenija, u literaturi može se naći značajan broj radova posvećen elektrohemisjkom formiranju nanostruktuiranih elektroprovodnih polimera, pa je upravo i ovaj tekst posvećen toj probelmatici, u prvom redu elektrohemisjkom formiranju nanostruktura polianilina i polipirola kao najznačajnijih predstavnika elektroprovodnih polimera.

AB  - The most common disinfectants for water treatment are based on chlorine and its compounds. Practically, water treatments with chlorine compounds have no alternative, since they provide, in comparison to other effective processes such as ozonization or ultraviolet irradiation, high residual disinfection capacity. Unfortunately, all of chlorine-based compounds for disinfection tend to degrade during storage, thus reducing the concentration of active chlorine. Apart from degradation, additional problems are transportation, storage and handling of such hazardous compounds. Nowadays, a lot of attention is paid to the development of electrochemical devices for in situ production of chlorine dioxide or sodium hypochlorite as efficient disinfectants for water treatment. The most important part of such a device is the electrochemical reactor. Electrochemical reactor uses external source of direct current in order to produce disinfectants in electrochemical reactions occurring at the electrodes. Construction of an electrochemical device for water treatment is based on evaluation of optimal conditions for electrochemical reactions during continues production of disinfectants. The aim of this study was to develop a low-cost electrochemical device for the production of disinfectant, active chlorine, at the place of its usage, based on newly developed technical solutions and newest commercial components. The projected electrochemical device was constructed and mounted, and its operation was investigated. Investigations involved both functionality of individual components and device in general. The major goal of these investigations was to achieve maximal efficiency in extreme condition of elevated room temperature and humidity with a novel device construction involving coaxial heat exchanger at the solution inlet. Room operation of the proposed device was investigated when relative humidity was set to 90% and the ambient temperature of 38°C. The obtained results in such extreme operation conditions reveled that it was possible to obtain required concentration of 0.85% of active chlorine with maximal temperature of outlet electrolyte of 35.3°C, which is within the limits of optimal temperatures.

Electrochemical synthesis was performed in 0.5 mol dm(-3) HCl and 0.2 mol dm(-3) pyrrole at constant current density of 2 mA cm(-2). Chronopotentiometric curves of polypyrrole enzyme electrode were recorded at current density of 42 nA cm(-2) for different glucose concentrations. The determined value of the apparent Michaelis-Menten constant was 0.045 mmol dm(-3) which is significantly lower than that of free enzyme indicating enhanced enzyme efficiency when it is immobilized into electroconducting polymer matrix.

AB  - Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and nitro- gen compounds on fracture surfaces and on the inner surface of the tubes. These compounds are specific agents that cause stress corrosion cracking (SCC) in brass. Analy- sis of fracture surfaces using scanning electron microscopy (SEM) has shown the brittle transgranular fracture due to the occurrence of SCC. The resistance of brass condenser tubes to other types of corrosion, such as erosion, general and selective corrosion (dezincification) is also considered. Some procedures are proposed to reduce the risk of SCC in the brass condenser tubes.
AB  - Analizirani su uzroci pojave loma kondenzatorskih cevi od mesinga CuZn28Sn1 u jednoj termoelektrani u Srbiji. Rezultati ispitivanja metodom Furijeove transformisane infracrvene spektroskopije (FTIR) ukazuju na prisustvo amonijačnih i azotnih jedinjenja na površini loma i na unutrašnjoj površini cevi. Ta jedinjenja su specifični agensi za pojavu naponske korozije mesinga. Analiza površine loma primenom skening elektronske mikroskopije (SEM) pokazala je prisustvo krtog transkistalnog loma nastalog usled pojave naponske korozije. Razmatrana je otpornost cevi od mesinga CuZn28Sn1 prema drugim vidovima koro- zije, kao što su eroziona, opšta i selektivna korozija (decin- kacija). Predloženi su postupci za smanjenje rizika od pojave naponske korozije u kondenzatorskim cevima.

abstract = "Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and nitro- gen compounds on fracture surfaces and on the inner surface of the tubes. These compounds are specific agents that cause stress corrosion cracking (SCC) in brass. Analy- sis of fracture surfaces using scanning electron microscopy (SEM) has shown the brittle transgranular fracture due to the occurrence of SCC. The resistance of brass condenser tubes to other types of corrosion, such as erosion, general and selective corrosion (dezincification) is also considered. Some procedures are proposed to reduce the risk of SCC in the brass condenser tubes., Analizirani su uzroci pojave loma kondenzatorskih cevi od mesinga CuZn28Sn1 u jednoj termoelektrani u Srbiji. Rezultati ispitivanja metodom Furijeove transformisane infracrvene spektroskopije (FTIR) ukazuju na prisustvo amonijačnih i azotnih jedinjenja na površini loma i na unutrašnjoj površini cevi. Ta jedinjenja su specifični agensi za pojavu naponske korozije mesinga. Analiza površine loma primenom skening elektronske mikroskopije (SEM) pokazala je prisustvo krtog transkistalnog loma nastalog usled pojave naponske korozije. Razmatrana je otpornost cevi od mesinga CuZn28Sn1 prema drugim vidovima koro- zije, kao što su eroziona, opšta i selektivna korozija (decin- kacija). Predloženi su postupci za smanjenje rizika od pojave naponske korozije u kondenzatorskim cevima.",

AB  - The electrochemically synthesized polypyrrole and lead-lead sulfate is examined as a potential electrodes for battery-type hybrid supercapacitors in acidic solution. The device exhibits battery-type behavior at low discharge rate, e.g. <0.5 A g−1, and supercapacitors-type behavior at a higher discharge rate. Discharge in the specific current range of ∼0.6–2.27 A g−1 based on the active masses, can deliver capacity of 90–72 Ah kg−1, energy of 58–40 Wh kg−1 and power of 40–1350 W kg−1, with the specific capacitance of the cell in the range of 300–250 F g−1. The experimentally obtained values are compared with theoretical.

Decolorization is investigated under open circuit potentials, and under external load of 3.3 kΩ conditions. In both cases, 40% of decolorization is achieved, but are three times faster under external load conditions. Specific energy during decolorization in such cell is estimated to ∼5 mWh/m2.

AB  - Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of prepared TiO2 nanoparticles and TiO2-PANI nanocomposite were determined by a transmission electron microscopy (TEM). The surface modification of TiO2 nanoparticles was confirmed by FTIR and UV–vis spectroscopy, while the morphology of PANI and TiO2-PANI nanocomposite was investigated by scanning electron microscopy (SEM). The influence of TiO2-PANI nanocomposite on glass transition temperature, dielectric and dynamic mechanical properties, thermooxidative stability, mechanical and anticorrosion properties of epoxy based nanocomposites was investigated and compared to the properties of epoxy/PANI nanocomposites. It has been observed that the glass transition temperature of epoxy resin increases after introduction of PANI and TiO2-PANI nanocomposite, as well as with increasing their content. Prepared nanocomposites exhibited higher value of dielectric constant than pure epoxy resin. Epoxy based coating containing TiO2-PANI nanocomposite showed lower dielectric loss, higher hardness and better anticorrosion properties than pure epoxy resin and epoxy/PANI nanocomposite.

Successive ion adsorption and reaction (SILAR) is applied to decorate an electrochemically formed TiO2 nanotube electrode. The anodic photoelectrochemical behavior of pure TiO2-NT’s and modified electrodes are investigated in a sulfate containing solution at pH = 9.2. It is shown that such a modification leads to an increase of anodic photoactivity, as well as that at the same current density, the photoelectrochemical cell with a modified electrode operates at a voltage lower by 0.7 V. The band gap and flat band potentials are estimated, and the structure of the band gap and possible charge transfer reactions and mechanism are discussed.

AB  - The objective of this research was to design an efficient continuously operated membrane reactor with a separation unit for egg white protein (EWP) hydrolysis and production of hydrolysates with improved antioxidant properties. For this purpose, a mechanically stirred tank reactor coupled with the polyethersulfone ultrafiltration module with a molecular weight cutoff of 10 kDa was employed. Several proteolytic enzymes have been tested in order to obtain the best quality of peptide-based formulations intended for human consumption. Among protease from Bacillus licheniformis (Alcalase), protease from Bacillus amyloliquefaciens (Neutrase), and protease from papaya latex (papain), the highest degree of hydrolysis (DH), as well as the best antioxidant properties of obtained hydrolysates, was achieved with Alcalase. The effects of operating variables such as enzyme/substrate ([E]/[S]) ratio, impeller speed, and permeate flow rate were further studied using response surface methodology (RSM) and Box–Behnken experimental design. Results obtained in RSM analysis confirmed that over the studied range [E]/[S] ratio, impeller speed and permeate flow rate had the significant effect on the DH and reactor capacity. The effects of different impeller geometries were also studied and four-bladed propeller stirrer enabled the highest DH. Antioxidant properties were analyzed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH), by the 2,2′-azino-bis-(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) radical scavenging activity, and by the linear voltammetry methods. Results show that the use of Alcalase in the membrane reactor system is of potential interest for the EWP hydrolysis and obtaining value-added egg products. © 2014, Springer Science+Business Media New York.

AB  - The copper sulfide is successfully deposited onto electrochemically formed polypyrrole, by successive ion-adsorption and reaction (SILAR) processes. The photoelectrochemical behavior of the polypyrrole, copper sulfide and copper sulfide modified polypyrrole are investigated in the sulfide based solution, under cathodic and anodic polarization. The improvement of the photooxidation stability, as well as activity of copper sulfide modified polypyrrole is achieved. Such behavior is explained by recombination of electrons from Cu2-xS conducting band with the holes of the PPy LUMO. © 2015 Elsevier B.V. All rights reserved.

abstract = "The copper sulfide is successfully deposited onto electrochemically formed polypyrrole, by successive ion-adsorption and reaction (SILAR) processes. The photoelectrochemical behavior of the polypyrrole, copper sulfide and copper sulfide modified polypyrrole are investigated in the sulfide based solution, under cathodic and anodic polarization. The improvement of the photooxidation stability, as well as activity of copper sulfide modified polypyrrole is achieved. Such behavior is explained by recombination of electrons from Cu2-xS conducting band with the holes of the PPy LUMO. © 2015 Elsevier B.V. All rights reserved.",

AB  - The protective abilities of composite coatings based on electrochemically and chemically formed polyaniline powder against the corrosion of mild steel were investigated. A polyaniline powder has been prepared in the form of an emeraldine base and benzoate salt through chemical dedoping and doping. The composite coatings using polyaniline powders, which were obtained through different routes, and base coatings, which were not corrosion-resistant, with different formulations were prepared and applied on mild steelsamples. The corrosion was investigated using an electrochemical impedance technique in 3% NaCl, andthe atmospheric corrosion was assessed in a humidity chamber. Emeraldine-benzoate salts, which area chemically synthesized polyaniline, offer the best protection with an optimal polyaniline concentration of approximately 5 wt%. The different corrosion behaviors were assessed relative to the presence of aniline oligomers in the samples after characterization using UV-vis spectrophotometry. Upon comparison between the corrosion behavior in 3% NaCl with commercial primer paint for iron and that with apaint containing 5 wt% PANI, the composite coating has superior anticorrosion characteristics. The mech-anism for the protection of mild steel from corrosion through composite polyaniline coatings was also considered. © 2014 Elsevier B.V. All rights reserved.
