AB  - The esters of substituted 1,4-dihydropyirdines (1,4-DHP) are formed in the reaction of an appropriate aldehyde and ethyl acetoacetate in the presence of concentrated water solution of ammonia. The esters form the amides by the reaction with primary amines. The series of the amides has been synthesized with the aim to analyze their chemical characteristics, antioxidant and antimicrobial activity. The amine used in this research is 2-aminothiazole. The antioxidant activity is analysed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) methods and the antimicrobial activity screening was performed by broth microdilution method, using different microbial strains. The characterization of the obtained amides was done by melting points, FTIR, NMR and elemental analysis. The possibilities for further research was suggested, which could lead to the application of selected compounds.

AB  - This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a vibration mill over the following times: 10, 20 and 30 min. Depending on the time required for the mechanical activation, the change in the filler grain size and shape was analysed along their effects on the talc-filled lost foam coating dispersion ability and stability. In order to characterize the filler, the following methods were used: X-ray diffraction, scanning electron microscopy and optic microscopy. The coating composition was tuned by choosing the suitable grain size and shape factor of the activated filler. In addition, different coating components (additives, solvent) were applied to alter the coating generation procedure. It was shown that the application of this type of the lost foam refractory coatings - water-based coatings - have a positive influence on quality of the aluminium alloy castings, which contributes to reducing the cost of cleaning and processing of the castings. Also, alcohol-based refractory coatings with talc-based activated fillers were tested and used to have the castings produced in the sand moulds.

AB  - The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. The examined compounds were synthesized by the reaction of isatin and substituted primary amines and characterized by spectroscopic methods. The investigation of the antimicrobial and antioxidative activity of the synthesized compounds was performed by broth microdilution method. As for the characterization of the investigated isatin based Schiff bases, the linear solvation energy relationships (LSER) were used to analyze the solvent influence on the UV absorption maxima shifts (V-max), using the well known Kamlet-Taft model and taking geometrical isomers into consideration when possible. Linear free energy relationships (LFER) were used to analyze substituent effect on pK(a), as well as NMR chemical shifts and v max values. The antimicrobial activity and characterization were related using both experimental and theoretical methods.

AB  - This study focussed on a comprehensive investigation on the state of pollution and identification of potential sources of contamination of some river sediments in Serbia by polycyclic aromatic hydrocarbons (PAHs), and is the basis for setting up further monitoring programs. The sediment quality of the Danube River (km 1433-845) and its tributaries in Serbia, including the Sava River (km 202-1), were analysed with respect to PAHs and total organic carbon (TOC). We found that total PAH concentration in the sediments from the Danube and its tributaries (10.0-4140 mu g kg(-1)) was lower than total PAH concentration in Sava River sediments (265.1-11272 mu g kg(-1)). Principal component analysis showed that concentrations of benzo[a]anthracene, chrysene, pyrene, fluoranthene, indeno[1,2,3- cd]pyrene, benzo[a] pyrene, benzo[b]fluoranthene and benzo[k]fluoranthene in the sediments were correlated with TOC. The diagnostic ratios anthracene/(anthracene+phenanthrene) and fluoranthene/(fluoranthene+ pyrene) were calculated to evaluate the emission sources of the PAHs. Therefore, these ratios indicated the predominantly pyrogenic source of the PAHs in the sediments. Results have also shown that river sediments in the Danube and Sava rivers and their tributaries were not recently polluted with PAHs, excluding only one location - S4, downstream of Sabac and characterized by heavily polluted sediment.

AB  - Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the C-13 NMR chemical shifts. The correlation analysis for the substituent-induced chemical shifts (SCS) with inductive (rI), and various resonance (rR) parameters were carried out through Single Substituent Parameter (SSP) and Dual Substituent Parameter (DSP) methods, and multiple regression analysis. Good Hammett correlations for all carbons were obtained, while electrophilic substituent constants better fitted for C2 carbon with electron-donor substituents. Conformational analysis of various derivatives using RB3LYP/6-311 ++G (3df,3dp) DFT method, together with C-13 NMR data suggests that most of the substituted orotic acid derivatives exist in planar conformation, except nitro and alkyl substituted derivatives. Internal rotation of carboxylic group showed significant impact on the extent of conjugative interaction making syn conformation more stable in all the derivatives studied. Further, of all 5-substituted orotic acid derivatives, diketo form proved to be the most stable form compared to zwitterionic and enol tautomeric forms. Optimized geometries and transmission effects of particular substituent through well-defined p-resonance units suggest that these units behave as isolated as well as conjugated fragments, depending on the type of substituent.

AB  - The substituent and solvent effects on solvatochromism in 3-[(4-substituted) phenylamino] isobenzofuran-1(3H)-ones were studied using experimental and theoretical methodologies. The effect of specific and non-specific solvent-solute interactions on the shifts of UV-Vis absorption maxima were evaluated using the Kamlet-Taft and Catalan solvent parameter sets. The experimental results were studied by density functional theory (DT) and time-dependent density functional theory (TD-DFT). The HOMO/LUMO energies (EHOMO/ELUMO) and energy gap (E-gap) values, as well as the mechanism of electronic excitations and the changes in the electron density distribution in both ground and excited states of the investigated molecules were studied by calculation in the gas phase. The electronic excitations were calculated by the TD-DFT method in the solvent methanol. It was found that both substituents and solvents influence the degree of p-electron conjugation of the synthesized molecules and affect the intramolecular charge transfer character.

AB  - The ratios of E/Z isomers of sixteen synthesized 1,3-dihydro-3-(substituted phenylimino)-2H-indol-2-one were studied using experimental and theoretical methodology. Linear solvation energy relationships (LSER) rationalized solvent influence of the solvent-solute interactions on the UV-Vis absorption maxima shifts (v(max)) of both geometrical isomers using the Kamlet-Taft equation. Linear free energy relationships (LEER) in the form of single substituent parameter equation (SSP) was used to analyze substituent effect on pK(a), NMR chemical shifts and v(max) values. Electron charge density was obtained by the use of Quantum Theory of Atoms in Molecules, i.e. Bader's analysis. The substituent and solvent effect on intramolecular charge transfer (ICT) were interpreted with the aid of time-dependent density functional (TD-DFT) method. Additionally, the results of TD-DFT calculations quantified the efficiency of ICT from the calculated charge-transfer distance (D-CT) and amount of transferred charge (Q(CT)). The antimicrobial activity was evaluated using broth microdilution method. 3D QSAR modeling was used to demonstrate the influence of substituents effect as well as molecule geometry on antimicrobial activity.

AB  - The examination results of the gelatinization of nitrocellulose gunpowders, stabilized by different stabilizers are described in this study. The microstructure of gunpowder samples of different chemical compositions is analyzed by the scanning electron microscopy (SEM). Apart from the three-dimensional picture of morphology and the effect of the molecular dispersion of stabilizers into the nitrocellulose matrix, the in­formation on chemical composition of the surface of gunpowder grain was obtained by the use of energy-dispersive X-rays spectrometry on SEM (SEM/EDX). The aim of the research was the comparative analysis of three different gunpowder samples, and the estimation of the effect on the gelatinization of nitrocellulose by different stabilizers was performed including their separate influences on the chemical stability of gunpowder. The comparative analysis is based on the degree of homogenous dispersion of each stabilizer in the matrix, which has the significant positive influence on the stability of gunpowder.

AB  - The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these precursor materials and modified with goethite nano-deposit, alpha-FeOOH, A1/ and A2/MWCNT-alpha-FeO(OH) adsorbents used for As(V) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on adsorption efficiency were studied. Adsorption data modelling by the Langmuir isotherm, revealed good adsorption capacities (in mg g(-1)) of 18.8 for As(V) and 60.1 and 44.2 for Pb2+ and Cd2+ on A2/MWCNT, respectively. Also, 27.6 and 29.8 mg g(-1) of As(V) on A1/ and A2/MWCNT-alpha-FeO(OH), respectively, were removed. Thermodynamic parameters showed that the adsorption is spontaneous and endothermic processes. Results of the study of influences of competitive ions: bicarbonate, sulfate, phosphate, silicate, chromate, fluoride and natural organic matter (NOM), i.e., humic acid (HA), showed the highest effect of phosphate on the decrease of arsenate adsorption. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate-controlling step. Also, activation energy (E-a/kJ mol(-1)): 8.85 for Cd2+, 9.25 for Pb2+ and 7.98 for As(V), were obtained from kinetic data.

Also, 27.6 and 29.8 mg g(-1) of As(V) on A1/ and A2/MWCNT-alpha-FeO(OH), respectively, were removed. Thermodynamic parameters showed that the adsorption is spontaneous and endothermic processes. Results of the study of influences of competitive ions: bicarbonate, sulfate, phosphate, silicate, chromate, fluoride and natural organic matter (NOM), i.e., humic acid (HA), showed the highest effect of phosphate on the decrease of arsenate adsorption. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate-controlling step. Also, activation energy (E-a/kJ mol(-1)): 8.85 for Cd2+, 9.25 for Pb2+ and 7.98 for As(V), were obtained from kinetic data.",

AB  - The derivatives of isatin (1H-indole-2,3-dione) have already been reported to show a variety of biological activities. However, there have hitherto been no reports on the solvatochromic effects of isatin derivatives, and it could be of interest to study and relate them to their electronic structures, as a part of the characterisation of these compounds. Linear solvation energy relationships (LSER) were used to analyze the influence of the solvent on the shifts of the UV absorption maxima of investigated isatin derivatives, i.e., isatin based Schiff bases, using Kamlet-Taft model. Linear free energy relationships (LFER) were applied to the substituent-induced NMR chemical shifts (SCS) using a single substituent parameter (SSP). The obtained correlations together with theoretical calculations gave insight into the influence of the molecular conformation on the transmission of substituent effects, as well as on solute-solvent interactions. The molecular electrostatic potential (MEP) surface map was plotted over the optimized geometry of the molecules in order to visualize the electron density distribution and explain the origin of the solvent- solute interactions.

AB  - Linear free energy relationships (LFER) were applied to the kinetic data for the reaction of 5-substituted orotic acids, series 1, with diazodiphenylmethane (DDM) in N,N-dimethylformamide and compared with results obtained for 2-substituted benzoic acids, series 2. The correlation analysis of the kinetic data with sigma substituent parameters was carried out using SSP (single substituent parameter) methods. From the sign and value of proportinality constant rho, lower sensitivity to the substituent effect was obtained in series 1, 0.876, than in the series 2, 1.877. Evaluation of substituent "ortho-effect" was performed using the Charton model, which includes the steric substituent parameter, and Fujita and Nishioka's model, which describes the total ortho-effect as contribution of ordinary polar effect, the ortho-steric and ortho-polar effects. Results of correlations, obtained by using the Charton model, showed highest contribution of the polar effect, 0.861 vs. 2.101, whereas the steric effect is of lowest significance, 0.117 vs. 0.055, for series 1 and 2, respectively. Also, a low negative value of coefficient with the steric effect, -0.08, obtained from the Fujita-Nishioka model indicated low steric effect, influencing a decrease of the reaction rate in series 1. The structural and substituent effects were also studied by using the density functional theory method, and together with kinetic data, it gave a better insight into the influence of the effect of both geometry and substituent on the pi-electron density shift induced reactivity of investigated acids. geometry and substituent on the pi-electron density shift induced reactivity of investigated acids.

AB  - The present study reports a new facile methodology for the synthesis of symmetrical and asymmetrical thioureas by a one-pot reaction of the required amine, carbon disulfide and an oxidant, i.e., hydrogen peroxide, ethylenediaminetetraacetic acid (EDTA)/sodium percarbonate system or air. The structures of the synthesized compounds were confirmed by IR, H-1- and C-13-NMR and MS methods. A reaction mechanism is proposed based on the isolation of reaction intermediate and the determination of their structure. The synthetic benefits of the presented methods are reflected in the operational simplicity, mild reaction conditions, short reaction times, solvent recycling, high purity and yield of the products, absence of dangerous by-products and technological applicability on an industrial scale. Considering the commercial importance of thioureas, it should be emphasized that implementation of the optimal synthesis of thiourea determined in this study for industrial production could provide a concurrent alternative to the existing technologies in use.

AB  - The morphological, thermal and barrier properties of low-density polyethylene/polycaprolactone-modified nanocellulose hybrid materials were investigated in this study. Nanocellulose/magnetite (NC-Fe3O4) nanocomposite and maleic acid functionalized NC/magnetite (NCMA-Fe3O4) nanocomposite were prepared and used as fillers at various concentrations (5, 10 and 15 wt. %) in the polycaprolactone (PCL) layer. PE was coated with a PCL/NC//magnetite layer. The addition of the filler did not unfavorably affect the inherent properties of the polymer, especially its barrier properties. Oxygen permeation measurements showed that the oxygen barrier properties of magnetite enriched PCL film were improved due to the chemical activity of the added material. The highest level of the barrier capacity was observed for PE samples coated with a PCL-based composite with NCMA-Fe3O4 micro/nanofiller, which implies a significant contribution of the surface modification of the nanocellulose with maleic anhydride residue to the improved barrier properties.

AB  - A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent precipitation of iron oxide (FO) from goethite on NC-PEG was employed to produce NC-PEG/FO adsorbent which was used for As(V) and As(III) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on the adsorption efficiency were studied. The maximum adsorption capacities found for Cd2+ and Ni2+, obtained by the use of Langmuir model, were 37.9 and 32.4 mg g(-1) at 25 degrees C, respectively. Also, high As(V) and As(III) removal capacities of 26.0 and 23.6 mg g(-1) were obtained. The thermodynamic parameters indicated endothermic, feasible and spontaneous nature of the adsorption process. The kinetic study, i.e., fitting by Weber-Morris model predicted that intra-particle diffusion was the rate-controlling step. The ability for multi-cycle reusability of both NC-PEG and NCPEG/FO, represents a positive indicator when considering their possible applications.

AB  - This paper reports the characteristics of the explosive TH-5, recycled (recovered) trinitrotoluene (TNT) with max. 5wt-% of hexogen (RDX). The explosive TH-5 was obtained by delaboration of warheads and melting of explosive charges based on TNT and RDX and by separation (extraction) of high explosive components. The thermal characteristics of pure (virgin) TNT and RDX, and recycled explosive TH-5 are determined by differential scanning calorimetry. The possibility of processing TH-5 by pressing and casting is also examined. The comparative analysis of sensitivity of TH-5 and TNT to friction is determined, as well as compressibility of explosives, and the detonation velocity of pressed and cast charges. Based on the analysis of experimental results, the defense standard requirements for the quality of TH-5 are defined and possibility of practical application of explosive TH-5 was estimated.

The possibility of processing TH-5 by pressing and casting is also examined. The comparative analysis of sensitivity of TH-5 and TNT to friction is determined, as well as compressibility of explosives, and the detonation velocity of pressed and cast charges. Based on the analysis of experimental results, the defense standard requirements for the quality of TH-5 are defined and possibility of practical application of explosive TH-5 was estimated.",

AB  - The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen solvents in the wavelength range from 200 to 400 nm. The position of the absorption maxima (λmax) of the examined acids showed that the ultraviolet absorption maximum wavelengths of picolinic acid N-oxide are the shortest, and those of isonicotinic acid N-oxide acid are the longest. In order to analyze the solvent effect on the obtained absorption spectra, the ultraviolet absorption frequen­cies of the electronic transitions in the carboxylic group of the examined acids were correlated using a total solvatochromic equation of the form Vmax = V0 + + Sπ*+ aα+ bβ, where Vmax is the absorption frequency (1/λmax), π*is a measure of the solvent polarity, β represents the scale of solvent hydrogen bond acceptor basicities and α represents the scale of solvent hydrogen bond donor acidities. The correlation of the spectroscopic data was carried out by means of multiple linear regression analysis. The solvent effects on the ultra­violet absorption maximums of the examined acids were discussed.

AB  - Quantitative structure-reactivity correlations for the kinetics of the Hantzsch synthesis of 4-(substituted phenyl)-1,4-dihydropyridines in the reaction between ethyl m- and p-substituted 2-benzylideneacetoacetate and the enamine (ethyl 3-aminocrotonate) was studied. The reaction kinetics was followed spectrophotometrically. It was found that the reaction correspond to second-order kinetics. Quantitative structure-reactivity correlations of log k were obtained with the corresponding substituent constants (s, s+, sI and s + ) using the Hammett and extended Hammett equation (dual substituent parameter, DSP, equation). They showed linear relationships with positive values of reaction constants (r). The obtained data were processed by linear regression analysis. It was confirmed that Michael addition of the enamine to benzylidene represented the slow step of the reaction with a high positive charge at the benzylidene molecule. MO calculations were performed and they were in agreement with the conclusions derived from the structure-reactivity correlations. .

The reactions were found to follow the second-order kinetics. The activation energy as well as the activation parameters, such as the standard entropy, the standard enthalpy, and the standard Gibbs energy of the activation, was calculated from the second-order rate constants. The solvent and structural effects on the activation energy and the standard Gibbs energy of activation, for each examined compound, were analyzed. The results of KamletTaft multiple correlation analysis show that the specific solventsolute interactions play a dominant role in the governing of the reaction.

AB  - Hammett correlations between the 13C-NMR chemical shifts of the azomethine carbon atom and the corresponding substituent constants were established for thirteen Schiff bases. The successful correlation of the chemical shifts with the electrophilic substituent constants s+ indicate a significant resonance interaction of the substituents on the aniline ring with the azomethine carbon atom in the examined series of imines. The demand for electrons in the investigated compounds was compared to that of the N-benzylideneanilines and N-(substituted phenyl)pyridinealdimines. The manner of transmission of the substituent effects is discussed and they were separated into resonance and inductive effects. The inductive effects prevail over the resonance effects.
AB  - 13C-NMR hemijska pomeranja 13 Šifovih baza korelisana su sa konstantama supstituenata korišćenjem Hametove jednačine. Dobra korelacija hemijskih pomeranja azometinskog ugljenika sa elektrofilnim konstantama supstituenata (s+) pokazuje da postoji izražena rezonantna interakcija supstituenata na anilinskom prstenu sa azometinskim ugljenikom. Ispitivan je prenos elektronskih efekata supstituenata i oni su razdvojeni na induktivne i rezonantne efekte, a pokazano je da preovlađuju induktivni efekti.

AB  - The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents were correlated using the Kamlet-Taft solvatochromic equation in the complete form: log k = log k0 + sπ*+ a( + bβ. The correlations of the kinetic data were realized by means of multiple linear regression analysis. The obtained results were analyzed in terms of the initial and the transition state of the reaction and compared with previously determined kinetic data for nicotinic acid. The signs of the equation coefficients (s, a and b) are in agreement with the reaction mechanism and the influence of the solvent on the reaction rate is discussed based on the correlation results. The mode of the transmission of the substituent effect is discussed in light of the contribution of solute-solvent interaction to the reactivity of the acid. The substituent effect was additionally analyzed by the Hammett equation, log k = pσ + log k0.
AB  - Konstante brzine za reakciju diazodifenilmetana (DDM) sa 2-susptituisanim nikotinskim kiselinama u devet aprotičnih rastvarača su određene na 30 °S. Dobijene konstante brzine za reakciju drugog reda su korelisane Kamlet-Taftovom totalnom solvatohromnom jednačinom u obliku: log k = log k0 + sπ*+ a( + bβ. Korelacija kinetičkih podataka izvršena je višestrukom linearnom regresionom analizom. Dobijeni rezultati su analizirani u odnosu na osnovno i prelazno stanje i upoređeni sa ranije određenim vrednostima za nesupstituisanu kiselinu. Znaci ispred koeficijenata u jednačini su u skladu sa pretpostavljenim mehanizmom reakcije. Diskutovan je prenos efekata supstituenata na reakcioni centar uzimajući u obzir doprinos efekata rastvarača na reaktivnost ispitivanih jedinjenja. Efekat supstituenata je dodatno analiziran Hametovom jednačinom: log k = pσ + log k0.
