AB  - Three glycoside hydrolases (α-amylase, xylanase and pullulanase) were immobilized on low-cost, environmentally friendly, easily modified clay rich in beidellite. Modifications included common procedures: Na-exchange, acid activation, pillaring, pillaring followed by acid activation, and organo-modifications with chitosan. Supports were characterized by chemical analysis, low temperature N2 physisorption, X-ray powder diffraction (XRPD) and Fourier-transform infrared (FT-IR) spectroscopy. The point of zero charge was also determined. Specific activity of different immobilizates of selected glycoside hydrolases was notably influenced by the type of chemical modification of supports. For each enzyme optimal support was chosen and storage stability was tested. α-Amylase immobilized on acid-activated support retained up to 95% of its initial specific activity of 105.6 ± 5.1 U g−1 after a testing period of 120 days. The most suitable support for xylanase was chitosan-modified beidellite with having specific activity of 90.0 ± 1.4 U g−1 which retained >50% its value after 120 days. Specific activity of pullulanase immobilized on pillared sample that was subsequently activated by acid was 44.5 ± 0.7 U g−1. Initial activity was preserved up to 33% for the same testing period. Comparing these results to the storage stability of the free enzymes that completely lost their activity for the longest period of 40 days, it can be concluded that appropriately modified beidellite- based clays could be used as suitable supports for stabilization of glycoside hydrolases. Nevertheless, further characterization of immobilizates (pH, thermal and operational stability) is needed in order to raise the suitability for larger scale processes in food industry.

AB  - In this paper, the influence of cobalt loading in pillared clay-supported cobalt materials on their electrocatalytic performance toward glucose oxidation was investigated. A series of aluminum-pillared montmorillonite clay (AP) materials with different cobalt loadings (x%CoAP, x = 1, 3, 5, and 10 wt%) was synthesized using the incipient wetness impregnation method. The X-ray powder diffraction (XRPD), inductively coupled plasma optical emission spectroscopy (ICP-OES), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy coupled with energy dispersive X-ray spectrometry (FE-SEM/EDX), high resolution transmission electron microscopy (HR-TEM) coupled with EDX, X-ray photoelectron spectroscopy (XPS), and low temperature N2 physisorption, were employed for characterization of the materials. The incorporation of cobalt in porous structure of pillared montmorillonite was confirmed. The synthesized materials (x%CoAP) were used for modification of carbon paste (CP) electrode and tested in reaction of glucose electrooxidation. The electrochemical measurements were conducted using cyclic voltammetry and chronoamperometry in a 1 M NaOH solution, with or without glucose. The results showed that the increase of cobalt loading improved the electrode performance toward glucose. The highest current response and sensitivity were obtained for the CP-5%CoAP electrode. A lower electrode performance of CP-10%CoAP was correlated with the presence of higher quantities of Co3O4 (confirmed by XRPD and XPS) in the electrode material. The mechanism and kinetics of glucose electrooxidation was studied in more details for the best performing electrode (CP-5%CoAP). It was found that the process was diffusion-controlled and the diffusion coefficient was determined. The charge transfer coefficient and catalytic rate constant were calculated. The electrode exhibited satisfactory repeatability, reproducibility, stability, and selectivity. The obtained results showed that appropriate amount of cobalt loading in pillared clay led to the obtainment of non-enzymatic electrode materials suitable for sustainable and green glucose sensors.

AB  - Aluminum pillared clay was synthesized and impregnated with Co2+ (CoAP), using incipient wetness impregnation method. The obtained CoAP was characterized by chemical analysis, XRPD, SEM with EDS, XPS and low temperature N2 physisorption. By these methods the incorporation of Co2+ was confirmed in both micro and mesoporous region. The synthesized material was investigated as a catalyst in catalytic oxidation of organic water pollutants – dyes – in the presence of Oxone® (peroxymonosulfate). Oxone® is a precursor of sulfate radicals. Tartrazine was chosen as a model dye pollutant. The influence of the mass of the catalyst, temperature and initial pH was investigated. Temperature increase was beneficial for dye degradation rate. The reaction rate was the highest for initial pH values around those corresponding to neutral conditions, somewhat slower for pH < 4 values, while for pH > 10 decolorization was significantly less expressed. Along with decolorization of tartrazine solution the formation and degradation of tartrazine catalytic oxidation products were monitored using UV–Vis spectroscopy. CoAP was found to be efficient catalyst in Oxone® induced catalytic degradation of both tartrazine and detected products of its degradation.

AB  - Aluminum pillared montmorillonite impregnated with cobalt (CoAP) was synthe-sized and characterized using chemical analysis, XRD and N-2-physisorption. CoAP was tested as a catalyst in the peroxymonosulfate (Oxone (R)) induced catalytic degradation of tartrazine. The influence of Oxone (R)/catalyst ratio and temperature on CoAP catalytic performance was investigated. The UV-Vis spectra obtained after predetermined periods of time of reaction were analyzed in order for tartrazine solution composition to be monitored. The reaction was more efficient at 50 degrees C than at 30 degrees C and the presence of new peaks for the reaction at 50 degrees C was observed. The peaks were deconvoluted and further analyzed. The intensity of two characteristic peaks gradually decreased during the investigated reaction following the first order kinetics. Newly formed peaks indicated the formation of degradation products. The initial increase of the intensity of some of them was followed by certain decrease as the reaction proceeded. CoAP was found to be efficient catalyst in Oxone (R) induced catalytic decolorization of tartrazine. The degradation of different products formed in tartrazine oxidation was evidenced.

AB  - Macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite was prepared by radical suspension copolymerization. Nanocomposite was functionalized with diethylenetriamine (DETA), by ring-opening reaction of the pendant epoxy groups. Functionalization was performed in order to enable phenol derivatives sorption. This new, not sufficiently investigated material, with developed porous structure was denoted CP-S-A-DETA. In this study, the influence of temperature on 4-nitrophenol (4NP) sorption on CP-S-A-DETA was investigated. The chemisorption was estimated as dominant process since activation energy of sorption of 4NP of 54.8 kJ mol(-1) was obtained. After determining the optimal sorption conditions for 4NP, the sorption of 2-nitrophenol (2NP) and 2-chloro-4-nitrophenol (2Cl4NP) on CP-S-A-DETA was investigated with respect to pH, initial concentration and contact time. The 2NP sorption was seldom tested, while according to our knowledge, the 2Cl4NP sorption was not investigated. The isotherm data were best fitted with Langmuir model, while the sorption dynamics obeyed the pseudo-second-order kinetic model for all derivatives.

AB  - Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated PGME-deta]. Samples were characterized by elemental analysis, mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Kinetics of Cr(VI) sorption by PGME-deta were investigated in batch static experiments, in the temperature range 25-70 degrees C. Sorption was rapid, with the uptake capacity higher than 80% after 30 min. Sorption behavior and rate-controlling mechanisms were analyzed using five kinetic models (pseudo-first order, pseudo-second order, Elovich, intraparticle diffusion and Bangham model). Kinetic studies showed that Cr(VI) adsorption adhered to the pseudo-second-order model, with definite influence of pore diffusion. Equilibrium data was tested with Langmuir, Freundlich and Tempkin adsorption isotherm models. Langmuir model was the most suitable indicating homogeneous distribution of active sites on PGME-deta and monolayer sorption. The maximum adsorption capacity from the Langmuir model, Q(max),at pH 1.8 and 25 degrees C was 143 mg g(-1) for PGME2-deta (sample with the highest amino group concentration) while at 70 degrees C Q(max) reached the high value of 198 mg g(-1). Thermodynamic parameters revealed spontaneous and endothermic nature of Cr(VI) adsorption onto PGME-deta.

AB  - In this study, a bioactive complex containing nonwoven textile material (polypropilene (PP)/viscose), chitosan hydrogel, and lidocaine hydrochloride, was designed. The purpose of such biomedical textile was in the treatment of painful sites. Mercury intrusion porosimetry was used in order to estimate the influence of medical impregnation on porous structure of nonwoven material. It was estimated that more than 97% of pores in untreated nonwoven sample were larger than 15 mu m. Anesthetic treatment of nonwoven reduced total pore volume of ultramacropores and macropores, while total pore volume of mesopores slightly increased. Lidocaine hydrochloride release from the anesthetic/chitosan hydrogel/nonwoven complex was measured in vitro by Franz diffusion cell technique. Mathematical model was developed to estimate the release of the lidocaine from obtained bioactive textile material. The diffusive transport of lidocaine hydrochloride through three connected layers, i.e., polymer hydrogel, membrane, and solution is modeled based on Fick's second law. Taking all the relevant conditions, regarding this experiment, into consideration, the coefficient of lidocaine diffusion through the polymer hydrogel, as well as the concentration ratio parameter were determined by the mathematical model.

AB  - Two porous samples and one non-porous sample of crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were synthesized by suspension copolymerization and functionalized by ring-opening reaction of the pendant epoxy groups with diethylene triamine (deta). Initial PGME, as well as amino-functionalized samples, were characterized by FT-IR spectroscopy, mercury porosimetry, scanning electron microsopy and elemental analysis. The kinetics of Cr(VI) sorption by amino-functionalized PGME was investigated in batch experiments under non-competitive conditions. It was found that the porosity of PGME-deta samples plays an important role in Cr(VI) uptake. Cr(VI) sorption by macroporous amino-functionalized samples was rapid, with the uptake capacity higher than 80% after 30 minutes. Two kinetic models (the pseudo-first and the pseudo-second order) were used to determine the best-fit equation for chromium(VI) sorption by PGME-deta.

AB  - The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties (rupture resistance and tensile strength) and slightly decreases sorptional properties (degree of water retention and rate of water absorption) of cloths. The optimum heat-treatment temperature needed to obtain the highest breaking force and water absorption of nonwovens is found to be 165-170 degrees C. Microstructural analysis proves that the nonwovens have the point bonding form of web when heat treatment is per-formed at optimum temperature.

AB  - The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with mechanical and dielectric properties that satisfy the quality needed for production of printed circuit boards for microelectronics. Commercial materials: glass woven fabric, different types of silane finish and epoxy resin were starting materials in obtaining composites.  The conditions needed for the thermal removal of the original size from glass fabric were investigated. The optimal heat treatment should be performed at temperatures less than 550 оC, while cooling rates should be as slow as possible. In this manner the fabric has less than 0.1% of residual size, and the mechanical properties remain satisfactory.Different types of adhesion promoters based on silanes were applied on heat-treated glass fabric as finishes. The quality of the composite material made of thermally and chemically treated glass fabric and epoxy resin was controlled by measuring the tensile and dielectric strength of composite. Depending on which properties of composite are of main concern, mechanical or dielectric, finish with amino functional group and lower heat treatment temperature or epoxy modified coatings and higher heat treatment temperature should be used for obtaining glass-fabric epoxy resin laminar composites.

AB  - The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the optical fiber through a reservoir with a die at the bottom. The reservoir was supplied with a dispersion of magnetic powder in a polymer solution. The effect of the dispersion viscosity, powder concentration and drawing rate on the uniformity of the composite coating thickness under laboratory conditions was investigated on a defined system to establish the optimal coating conditions. Dispersions were formed by dispersing different concentrations of Ba-ferrite in a poly(ethylene-co-vinyl acetate) solution in toluene. The thickness of the coatings and its uniformity were determined by microscopic analysis and further evaluated by mathematical-statistical analysis. The smallest standard deviation (S.D.) of the mean value of the diameter of the optical fiber with a composite coating was chosen as the criteria for defining the most uniform composite coating. The results show that the most uniform coatings were obtained with a dispersion viscosity whose value was about 1.2 Pa s. All the process parameters should be established in accordance with this viscosity value, enabling the formation of the most uniform composite coating for the investigated system.

AB  - A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological behavior of the investigated dispersed system. The model was developed for a dispersed system consisting of poly(ethylene-co-vinyl acetate) - EVA in a form of toluene solution and powders of magnetic materials (BaFe12O19 and SmCo5). The influence of the die diameter, diameter of the original optical fiber, concentration of EVA and magnetic powders on the thickness of composite coating was investigated. The model shows good agreement with experimental data.

AB  - A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of temperature, and the glass emissivity was defined and calculated as a function of both temperature and glass thickness. After allowed simplifications, two ordinary differential equations were obtained and solved using the Runge Kutte method. The model was used to investigate the influence of different process parameters (the velocity of lowering the preform into the furnace, the axial temperature profile of the furnace, the drawing force and its direction, etc.) on the change in the shape of the drawn glass sheet for different glass compositions and various geometrical characteristics of the preform. A laboratory device for drawing thin glass sheets from rectangular preforms enabled full control of the process parameters, their measurement, as well as data acquisition. The results of the numerical simulation were compared with the experimental data and good agreement between them was found.

AB  - The purpose of this investigation was to establish the correlation between the sintering conditions (temperature and time) and the stability of the SmCo5 phase, expressed by the intensity of its most important diffraction peak. The sintering and heat treatment was performed under a vacuum of 150 Pa. Sintering was investigated in the temperature interval from 1100 to 1180 degrees C, for sintering times of 30, 45 and 60 min, while the temperature and duration of the heat treatment were kept constant. The content of the SmCo5 phase, as the carrier of the magnetic properties, was observed by X-ray diffraction analysis of the polycrystalline specimens. It was established that there is a dependence of the intensity of the diffraction peak, which corresponds to the (111) plane of the SmCo5 phase, on the sintering time and temperature. A regression model was obtained that showed the intensity of the diffraction peak to be dependent upon squares of both the sintering time and temperature.
