AB  - У овом раду, отпадна биомаса Аrundo donax (АД) је коришћена за адсорпцију Ni2+ из водених раствора. Површина АД је карактерисана СЕМ и ФТИР методама анализе. Адсорпциони експерименти су изведени у шаржним условима, при почетној pH вредности раствора pHi = 7 и различитим почетним концентрацијама Ni2+. Процес адсорпције је боље описан Фројндлиховим него Лангмировим моделом, односно адсорпција је вишеслојна са хетерогеном расподелом активних центара на површини материјала. Кинетика адсорпције Ni2+ на АД јe боље описана моделом псеудо–другог реда него моделом псеудо–првог реда, што указује на успостављање хемијских интеракција између адсорбата и слободних места на површини адсорбената. Добијени резултати су указали да АД има потенцијал за пречишћавање вода загађених никлом.
AB  - In this paper, Arundo donax (AD) waste biomass was used for the adsorption of Ni2+ from aqueous solutions. The AD surface was characterized by SEM and FT-IR analysis. Adsorption experiments were carried out in the batch adsorption system, at an initial pH value of pHi = 7 and different initial Ni2+ concentrations. The adsorption process was better described by Freundlich’s than by Langmuir’s model, i.e. adsorption is multilayered with a heterogeneous distribution of active sites on the material surface. The kinetic study of Ni2+ adsorption showed that pseudo–second order was the model that better described the experimental adsorption data compared to pseudo first order model, indicating the formation of chemical interactions between adsorbate and free sites on the adsorbent surface. The obtained results indicated that AD has the potential for the remediation of nickel-polluted waters.

AB  - A convenient and efficient approach toward the synthesis of six 3-(4-substituted benzyl)-6,7-benzo-1,3-diazaspiro[4.5]decane-2,4-diones (1‒6) by Bucherer-Bergs reaction and further alkylation at position 3 of the hydantoin ring is reported. Further, their chemical structure was confirmed by melting points, elemental analysis, FT-IR, NMR and UV–Vis spectroscopic methods. To gain an insight into interactions which the investigated spirohydantoins establish with their environment, their absorption spectra were recorded in selected solvents of different polarity and the solvent effects on the UV-Vis absorption band positions, intensity and shape, were discussed. Substiuent effects on the solvatochromism of compounds 1−6 were analyzed using the Hammett's equation. Considering the broad applications of hydantoin derivatives, as well as the fact that their relative importance may increase in the future, results obtained in this study serve as a basis for further investigations.

AB  - Five novel D-π-A structured pyridinium based compounds, bearing different electron-donating units were synthesized, minutely characterized, and their solvatochromic and electronic properties were investigated. Subsequently, these compounds were added to a liquid electrolyte in order to enhance the photovoltaic performance of the N719-sensitized solar cell. It was demonstrated that the utilization of all compounds improved the conversion efficiency, compared to the reference solar cell comprised of plain liquid electrolyte. The photovoltaic performance of the fabricated DSSC depended of the electron-donating moiety of the synthesized compound. The highest photovoltaic conversion efficiency of 4.11% was obtained for DSSC with the compound bearing the 4-(N,N-dimethylamino)phenyl group.

AB  - In order to improve the performance of theoretical UV–Vis spectra predictions, a theoretical and experimental study of solvatochromic properties of ten azo pyridone dyes has been performed. For quantitative estimation of intermolecular solvent–solute interactions, a concept of the linear solvation energy relationships has been applied using Kamlet-Taft and Catalán models. Theoretical UV–Vis spectra for all dyes have been calculated using four TD-DFT methods in nine different solvents with the aim to define the most reliable model. Finally, new polylinear equations for more accurate theoretical prediction of UV–Vis maxima are developed using empirical Kamlet-Taft and Catalán solvent parameters as additive corrections for specific and nonspecific solvent–solute interactions.

Fourier Transform-infrared and nuclear magnetic resonance (NMR) spectra prove the existence of the hydrazone form in the solid state and in dimethyl sulphoxide, which is also supported by vibrational and NMR theoretical studies. Ultraviolet (UV) spectral properties, as well as solvatochromism in 19 solvents of different polarity, are investigated. In most of the solvents, the dye is solely present in the hydrazone form, whereas in certain solvents, an acid–base equilibrium exists. Excellent agreement between computational and experimental UV–visible data was established. Frontier Molecular Orbital analysis was performed and proved the existence of intramolecular charge transfer through the dye molecule. A molecular electrostatic potential surface was plotted over the optimised geometry to lighten the reactivity of the investigated molecule.
