AB  - The adsorption of Ni2+ ions from water solutions by using hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA) was studied. Hydrogel synthesis was optimized with response surface methodology (RSM). The hydrogel with the best adsorption capacity towards Ni2+ ions was chosen for further experiments. The hydrogel was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and atomic force microscopy (AFM) analysis before and after the adsorption of Ni2+ ions. Batch equilibrium experiments were conducted to investigate the influence of solution pH, hydrogel weight, ionic strength, adsorption time, temperature and initial concentration of nickel ions on the adsorption. Time-dependent adsorption fitted the best to the pseudo-second-order kinetic model. A thermodynamic study revealed that the adsorption was an exothermic and non-spontaneous process. Five isotherm models were studied, and the best fit was obtained with the Redlich-Peterson model. Consecutive adsorption/desorption studies indicated that the HEA/IA hydrogel can be efficiently used as a sorbent for the removal of Ni2+ ions from the water solution. This study develops a potential adsorbent for the effective removal of trace nickel ions.

AB  - A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were examined in solvents of various polarities and at different pH values. The solvent effects on the absorbance and emission spectral shift were analyzed using Lippert-Mataga, Reichardt-Dimroth and Kamlet-Taft equations. Moreover, UV-Vis absorption and emission frequencies were correlated with Hammett substituent constants applying the linear free energy relationships. DFT calculations of the investigated dyes were accomplished to determine their structural and electronic properties.

AB  - Thermo-oxidative degradation of mollusk shells to CaO through intermediate phase of CaCO3 has been investigated using various analytical techniques. Powders of shells species (Dosinia exoleta and Ostrea edulis), with particle size fractions of 0.045 - 0.125 mm, 0.125-0.2 mm, and 0.2-1 mm, were subjected to degradation at the various heating rates (5, 10, 15 and 20 degrees C min(-1)). Degradation pathway of this carbonate-rich waste material has not yet been analyzed in detail at particulate level. Understanding transformation process in air should lead to control over yield and morphology of final product. Thermogravimetric analysis (TGA) and X-ray diffraction (XRD) techniques were used to benchmark transformation steps at different heating rates and final decarbonation temperatures, while scanning electron microscope (SEM) was used to analyze the effect of temperature on evolution of morphological changes for particles of different fractions. It was found that sintering in the presence of carbon dioxide (CO2) could be triggered by agglomeration of CaO crystals, enhanced by CO2 adsorption that increases surface energy.

AB  - Polyphenols present in different plant cell organelles increase the resistance of plants to various types of environmental stresses. We investigated the possibility of increasing the content of bioactive compounds in the seed of yellow soybean variety Laura. The soybean was treated during vegetation with five products based on plant extracts, on the assumption of enrichment of plants with various nutrients. Soybean flour extracts were screened spectrophotometrically for total phenolic content and antioxidant activity. The antioxidant activity was evaluated using three methods. The content of phenolic acids was determined by HPLC, and the raw protein content was estimated by the Kjeldahl method. Depending on the treatment, variations in the quantity of individual phenolic acids with up to 90% higher concentration as compared to the control were observed. Controlled usage of certain plant extracts can increase the concentration of the target group of bioactive compounds in the samples. The synergistic effect of proteins and phenolic compounds on the antioxidant activity of extracts was detected. The results of this study are not only important from the aspect of plant resistance to various types of stress, but also when considering soybean as a functional food.

AB  - The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate as prevailing products were obtained in reactions with coconut, linseed, and sunflower oils, respectively. By using response surface methodology, the influences of key experimental factors-reaction time, substrates, and enzyme concentrations-for transesterification of esculin with linseed oil were investigated. High molar conversion (78.5%), product yield (19.13 mg/mL), and specific yield (2.83 mmol/g(enzyme)) were achieved at optimized conditions. Determined optimums were successfully applied in esculin transesterification with other two oils. Furthermore, esculin ester mixtures were incorporated in gel emulsions, and their effect on transepidermal water loss (TEWL) as well as skin sensitivity was examined. Obtained results have shown significant hydration effect and good dermatological compatibility without irritating effects of all examined preparations containing oil-derived esculin esters, making them very prospective for application in skin care products.

AB  - Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by self-propagating room temperature method and thermally treated at 600, 900 and 1200 degrees C for 15 min. The structure, morphology and optical properties, as well as thermal stability of Ce1-xErxO2-delta and Ce1-xPrxO2-delta (x = 0.05) were examined. Single-phase composition of all obtained CeO2 pigments was confirmed using XRPD method and Raman spectroscopy and it was not dependent on temperature. The mechanism of structural behaviour was thoroughly examined using Raman and FTIR spectroscopy. Nanometric dimensions of the crystallites of all pigments were confirmed using XRPD, TEM and FE-SEM analysis. Colour properties were dependent on the temperature treatment, and their position in the chromaticity diagram was studied using UV/VIS spectrophotometry. Colour efficiency measurements were supplemented by colorimetric analysis. It is proved that all samples are thermally stable in the investigated temperature range (up to 1200 degrees C), and their potential application as environmentally friendly pigments of desired colour is confirmed.

AB  - This paper describes the pyrolysis of Poplar fluff (from Populus alba) using on-line apparatus, and carbonization process at 850 degrees C using the fixed bed reactor. Characteristics of pyrolysis products were examined. Elemental and chemical analyses were shown that Poplar fluff has higher energy content characterized by increased content of fibrous structure (particularly cellulose). Independent parallel reactions model very well describes devolatilization process. It was found that increased amount of extractives can significantly affect on increased release of light gaseous products, but declining hydrocarbons, mostly the alkanes. Liquid product is mainly composed of phenolics, aldehydes, acids, esters and ketones. The carbonization process produces the great abundance of polycyclic aromatic hydrocarbons (PAH's), where naphthalene is the most abundant. Mechanism for PAH's formation was suggested. This study represents the first step in a much wider and more comprehensive way in thermal conversion processes of this type of fuel.

This study represents the first step in a much wider and more comprehensive way in thermal conversion processes of this type of fuel.",

AB  - In the first part of this work hydrogels based on 2-hydroxyethyl acrylate and itaconic acid P(HEA/IA) were prepared by free radical cross-linking copolymerization. In order to investigate the influence of the hydrogel composition on heavy metal sorption efficiency, series of the hydrogels with different amount of the itaconic acid were prepared (2.0, 5.0, 7.0 i 10.0 mol %). The swelling kinetics was carried out in buffers of different pHs and in destiled water. Further, the samples were characterised by Fourier transform infrared spectroscopy (FTIR), dynamic-mechanical analysis (DMA), scanning electron microscopy (SEM), atomic force microscopy (AFM) and differential scanning calorimetry (DSC). In the second part of this work, the P(HEA/IA) hydrogels were investigated as potential sorbents for removal of Pb2+, Cd2+ i Ni2+ ions from aqueous solution. In order to evaluate sorption behavior of samples various factors affecting the uptake of heavy metal ions behavior, such as: contact time, temperature, pH, ionic strength, sorbent weight, competitive ions and initial concentration of the metal ions were investigated. Five adsorption isotherms (Langmuir, Freundlich, Redlich-Peterson, Temkin i Dubinin-Raduskevich) and two kinetic models were studied (Lagergren pseudo-first order and pseudo-second order kinetics). The sorption process in multicomponent heavy metal ion system was also investigated, since the natural and industrial effluents rarely contain a single heavy metal ion, and some of the ions in the effluent may reduce the sorption of others or may be co-adsorbed along with other ions. At the end, desorption and the potential reausability of P(HEA/IA) hydrogels was examined. All results indicate that the P(HEA/IA) hydrogels could be used as promising sorbents for the removal of Pb2+, Cd2+ i Ni2+ ions from aqueous solution due to their high sorption capacity, good mechanical properties and possibility of reuse.
AB  - U prvom delu ovog rada su polimerizacijom preko slobodnih radikala sintetisani hidrogelovi na bazi 2-hidroksietil akrilata i itakonske kiseline (P(HEA/IK)). Tokom sinteze hidrogelova varirani su udeli itakonske kiseline (2,0, 5,0, 7,0 i 10,0 mol % IK) kako bi se ispitao uticaj sastava hidrogela na efikasnost sorpcije teških metala. Karakterizacija dobijenih uzoraka je izvedena ispitivanjem kinetike bubrenja u puferima razliţitih pH vrednosti kao i bubrenjem u destilovanoj vodi, primenom infracrvene spektroskopije sa Furijeovom transformacijom (FTIR), skenirajuše elektronske mikroskopije (SEM), dinamiţko-mehaniţke analize (DMA), mikroskopije atomskih sila (AFM) i diferencijalne skenirajuše kalorimetrije (DSC). U drugom delu ovog rada ispitana je mogušnost uklanjanja jona Pb2+, Cd2+ i Ni2+ iz vodenih rastvora pomošu P(HEA/IK) hidrogelova. Ispitan je uticaj pH sredine, mase sorbenta, uticaj soli, temperature i poţetne koncentracije metala na stepen uklanjanja. Ispitano je pet modela adsorpcionih izotermi (Langmuir-ov, Freundlich-ov, Redlich-Peterson-ov, Temkin-ov i Dubinin-Raduškeviţ-ev), a kinetika sorpcije metala je analizirana preko dva najţešše upotrebljavana modela (Lagergren-ovog kinetiţkog modela pseudo-prvog reda i Ho-ovog kinetiţkog modela pseudo-drugog reda). Obzirom da se u otpadnim vodama vrlo ţesto moţe naši veši broj metala, ispitan je i uticaj konkurentnih jona na proces sorpcije Pb2+, Cd2+ i Ni2+. Na kraju je ispitana mogušnost desorpcije metala sa sorbenata odgovarajušim desorpcionim sredstvima i ispitana mogušnost ponovne upotrebe hidrogelova kao sorbenata. Rezultati pokazuju da su P(HEA/IK) hidrogelovi pogodni kao sorbenti za uklanjanje jona Pb2+, Cd2+ i Ni2+ iz vodenih rastvora, pre svega zbog dobrog kapaciteta sorpcije, mogušnosti ponovne upotrebe i dobrih mehaniţkih svojstava, što je veoma vaţno za praktiţnu primenu

AB  - In order to improve the efficiency of pharmacotherapy by development of the sophisticated drug delivery systems, two series of hydrogels were synthesized in this study. Hydrogels were synthesized by the free-radical crosslinking polymerization at 50 °C for 24 h. In the first series the polymeric hydrogels are based on 2-hydroxyethyl acrylate and itaconic acid, whereas in the second series the samples are based on 2-hydroxypropyl acrylate and itaconic acid. In order to investigate the influence of the hydrogel composition on its properties in both series of the hydrogels amount of the itaconic acid was varied (0.0; 2.0; 3.5; 5.0 and 7.0 mol %). The started monomers were selected as structural analogs of 2-hydroxyethyl methacrylate which is thoroughly investigated and widely used monomer especially in biomedical and pharmaceutical applications. In order to improve the hydrophilicity and pH-sensitivity of the synthesized copolymers itaconic acid was used. The hydrophobic drug - oxaprozin was successfully synthesized and incorporated into the hydrogels by diffusion method. For evaluation of synthesized hydrogels as polymeric matrices for drug delivery complexes of oxaprozin with transition metal (Ni(II) and Zn(II)) as potential antiproliferative agents were used also. In order to investigate the influence of the chemical composition and of the presence of drug on the properties of synthesized hydrogels, chemical structure, morphology, thermal properties, swelling and „intelligent’’ behavior of synthesized hydrogels were examined. The entrapment efficiency of drug into synthesized hydrogels and their application in controlled drug delivery systems were investigated. The therapeutic benefits of the oxaprozin are accompanied with several serious side effects in upper gastrointestinal tract. The goal of this study was to design the polymeric matrices which can prevent the release of oxaprozin in the acidic environment of the stomach and reduce its side effects in upper part of the gastrointestinal tract.

AB  - A series of poly(2-hydroxyethyl acrylate-co-itaconic acid), P(HEA/IA), hydrogels with different HEA/IA ratio, were synthesized using free radical crosslinking/copolymerization and investigated as sorbents for Pb2+ from aqueous solutions. Hydrogels were characterized using DMA, FTIR, DSC, SEM and AFM. The adsorption was found to be highly dependent on hydrogel composition, solution pH, sorbent weight, ionic strength and contact time. Five isotherm models, Langmuir, Freundlich, Redlich-Peterson, Temkin and Dubinin-Radushkevich, were applied to the sorption data. The best fit was obtained with Redlich-Peterson isotherm. The separation factor, RL, value indicated favorable sorption for Pb2+. The maximum sorption capacities were 392.2 and 409.8 mg/g for P(HEA/2IA) and P(HEA/10IA), respectively. Kinetic data showed best fit with pseudo-second-order model. Thermodynamic studies revealed that the reaction was exothermic and proceeds with a decrease in entropy. Moreover, P(HEA/IA) hydrogel showed the most pronounced sorption toward Pb2+ from environment containing Cu2+, Zn2+, Cd2+, Ni2+ and Co2+. Sorption/desorption experiments, showed that the P(HEA/IA) hydrogels could be reused without significant loss of the initial properties even after three adsorption-desorption cycles.

AB  - Series of novel dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels were designed as multifunctional drug delivery system which can provide several advantages including drug protection, self-regulated oscillatory release and targeted delivery to a single entity. The hydrogels were synthesized by the free-radical crosslinking copolymerization and evaluated as carriers for hydrophobic drug, Oxaprozin, with specific controlled release properties.

AB  - Series of novel hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), P(HEA/IA) copolymers, were prepared by free radical cross-linking copolymerization and investigated as potential adsorbents for Cd2+ removal from aqueous solution. The hydrogels before and after Cd2+ adsorption were characterized using FTIR, temperature sensitive. In order to evaluate adsorption behavior of samples various factors affecting the Cd2+ uptake behavior, such as: contact time, temperature, pH, ionic strength, adsorbent weight, competitive ions and initial concentration of the metal ions were investigated. Five adsorption isotherms and two kinetic models were studied. The adsorption behavior can be very well described by the pseudo-second order kinetic model and Langmuir isotherm. Multicomponent adsorption studies revealed that adsorption of cadmium depends on the type of metal ions present in the system. Desorption studies showed that hydrogel can be reused three times with only 15% loss of adsorption capacity. All results indicate that the sample with the highest IA content is the most promising adsorbent for Cd2+ removal.

AB  - The effects of heating mode (conventional and microwave) on the kinetics of isothermal polymerization of MMA composite materials were investigated. Isothermal kinetics curves at temperature range from 343 K to 363 K for both conventional (CH) and microwave heating (MWH) were determined. It was found that the polymerization of MMA composite materials was kinetically elementary reaction for both CH and MWH. The kinetics of CH polymerization can be described by the model of phase-boundary controlled process (contracting volume), whereas the kinetics of MWH polymerization can be described by the model of first-order chemical reaction. The kinetics parameters (E-a and In A) of the polymerization under microwave heating are lower than for conventional heating. The established decreases in the activation energy and pre-exponential factor under the MWH compared to the CH is explained with the increase in the energy of ground vibrational level of the C-O valence vibrations (v = 987 cm(-1)) in methyl methacrylate molecule and with the decrease in its anharmonicity factor which is caused with the selective resonant transfer of energy from the energetic reservoir to the oscillators in methyl methacrylate molecules.

AB  - Thermal characterization and kinetic analysis of non-isothermal decomposition process of Bauxite red mud were carried out using thermogravimetry (TG), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), differential thermal analysis (DTA) and Fourier transform infrared spectroscopy (FTIR). It was found that the investigated decomposition was a complex heterogeneous process, which included two main decomposition stages and one sub-stage. The overall decomposition process consisted of the series of parallel and competitive reactions, which originated from the decomposition of various chemical species and solid-state transformations. This behavior was confirmed by the appearance of different forms of density distribution functions of apparent activation energy values. Furthermore, the conversion range of 0.10  LT = alpha  LT = 0.30, with a constant value of the apparent activation energy (146.4 kJ mol(-1)) for the second stage of the overall process, belongs to calcite decomposition, which takes place through a two-dimensional diffusion mechanism.

AB  - The kinetics of multi-step thermal degradation of Co(II) complex with N-benzyloxycarbonyl glycinato ligand [Co(N-Boc-gly)(2)(H2O)(4)]center dot 2H(2)O, in non-isothermal conditions was studied using isoconversional and non-isoconversional methods. The degradation of complex occurs in three well-separated steps involving the loss of water molecules in first step followed by two degradation steps of dehydrated complex. The dependence of Arrhenius parameters on conversion degree showed that all observed steps of thermal degradation are very complex, involving more than one elementary step, as can be expected for most solid-state heterogeneous reactions with solid reactants and solid and gaseous products. It was shown that step 1, corresponding to the dehydration, involves a series of competitive dehydration steps of differently bound water molecules complicated by diffusion. Second step involves two parallel reactions related to the loss of two identical C6H5CH2O-ligand fragments complicated by the presence of products in gaseous state. Further degradation in step 3 corresponds to complex process with a change in the limiting stage, in this case from the kinetic to the diffusion regime, connected with the presence of gaseous products diffusing through the solid product.

AB  - Multi-step thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n) in non-isothermal conditions was studied. The kinetic parameters were determined from the thermal decomposition data using the isoconversion and non-isoconversion techniques. It was shown that the coordination polymer is stable up to 60 C, when the multi-step process of thermal dehydration, followed by steps of degradation, starts. The kinetic triplet for the step of dehydration was established as f(alpha) = 3/2(1 - alpha)(2/3)[1 - (1 - alpha)(1/3)](-1). E-inv = 170.4 +/- 6.4 kJ mol(-1) and Z(inv) =2.6 x 10(23). The established kinetic model, known as "D3 model", was confirmed by application criteria defined by Malek, Perez-Maqueda et al. as well as Master plot method. Dehydration step is followed by two steps of dehydrated coordination polymer degradation. On the base of the dependence of Arrhenius parameters (E-a and Z) on conversion degree (alpha), the mechanisms of degradation were discussed. In this way it was shown that second and third steps of degradation of coordination polymer are complex involving more than one elementary step. The second step corresponds to the loss of two C6H5CH2O- fragments in two parallel steps. The third step of degradation, ascribed to the loss of two -C(=O)NHCH2- fragments, is complicated by changing kinetically to diffusion control. (C) 2011 Elsevier B.V. All rights reserved.

Dehydration step is followed by two steps of dehydrated coordination polymer degradation. On the base of the dependence of Arrhenius parameters (E-a and Z) on conversion degree (alpha), the mechanisms of degradation were discussed. In this way it was shown that second and third steps of degradation of coordination polymer are complex involving more than one elementary step. The second step corresponds to the loss of two C6H5CH2O- fragments in two parallel steps. The third step of degradation, ascribed to the loss of two -C(=O)NHCH2- fragments, is complicated by changing kinetically to diffusion control. (C) 2011 Elsevier B.V. All rights reserved.",

AB  - Differential scanning calorimetry (DCS) has been used to determine thermodynamic profile of pepsin and the in vitro effect of Al(III) ions. Thermograms of pepsin unfolding in the presence and absence of aluminum were used to determine the binding constant, KL, in the pepsin–aluminium model system. The thermodynamic parameters were derived from DSC profiles at different ligand concentrations (1, 5 and 10 mM). The temperatures of thermal transitions (Tm), calorimetric (ΔHcal) and van’t Hoff enthalpy (ΔHVH), Gibbs free energy, Δ(ΔG), of Al(III) binding to pepsin, as well as an average number of ligands bound to the native protein, were obtained from DSC profiles too. Temperature-dependent changes in the protein structure were also monitored by native PAGE electrophoresis. Increasing the temperature causes the decrease in electrophoretic mobility. Increase in concentration of Al(III) decelerate the migration of pepsin samples on concentration dependent manner. Analysis showed that ligand binding increases thermal stability of protein.
