AB  - In an attempt to reuse fibrous textile waste and, at the same time, to address dye pollution
in textile wastewater, waste cotton-based yarn was utilized as a cheap and sustainable adsorbent, as
well as a row material for carbon adsorbent production. Unmodified yarn and cotton-based carbon
adsorbents were used as adsorbents for dye removal from water. Cotton and cotton/polyester yarn
samples underwent thermal modification through carbonization followed by chemical activation
with KOH. Various techniques, including scanning electron microscopy, Fourier transform infrared
spectroscopy, nitrogen adsorption–desorption isotherms, and surface charge determination, were
employed to analyze the morphological and surface characteristics of the cotton-based adsorbents.
Adsorption properties were evaluated by testing the removal of selected cationic and anionic dyes
from water. The impact of temperature, initial pH and concentration of the dye solution, and
contact time on adsorption were investigated, and experimentally obtained data were analyzed using
theoretical models. While carbonization alone did not significantly enhance adsorption properties,
activated samples exhibited high efficacy in removing both cationic and anionic dyes from water.
Despite the negative influence of the polyester component in the carbon precursor on the efficiency
of activated samples in removing methyl orange, the results indicated that activated cotton and
cotton/polyester yarn could be used to prepare highly efficient adsorbents for the rapid removal of
methylene blue from real wastewater samples.

AB  - Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from aqueous solutions. Chemical modification and/or activation were applied to alter surface characteristics and to increase the adsorption and desorption efficiency of carbon materials. Surfaces of treated and untreated carbon materials were characterized through the examination of the textural properties, the nature of surface functional groups, and surface acidity. It was found that the adsorption capacity of tested carbon materials is not directly proportional to the specific surface area and the content of surface oxygen groups. However, a high ratio of surface mesoporosity affected the adsorption process most prominently, by increasing adsorption capacity and the rate of the adsorption process. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data were best fitted with the Langmuir isotherm model. Calculated mean adsorption energy values, along with the thermodynamic parameters, indicated that removal of selected hormones was dominated by the physisorption mechanism. High values of adsorption efficiency (88-100 %) and Langmuir adsorption capacities (29.45-194.7 mg/g) imply that examined materials, especially mesoporous carbon cryogel and multi-walled carbon nanotubes, can be used as powerful adsorbents for relatively fast removal of estrogen hormones from water.

AB  - In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published influence that boron has on characteristics of carbonized boron-doped hydrothermal carbons (CHTCB). Hydrothermal carbons doped with boron (HTCB) were obtained by the hydrothermal synthesis of glucose solutions with different nominal concentrations of boric acid. It was found that glucose based hydrothermal carbon does not have developed porosity, and the presence of boron in their structure has insignificant influence on it. On the contrary, additional carbonization increases the specific surface area of the undoped sample, while an increase in boron content drastically decreases the specific surface area. Boron doping leads to a decrease in the amount of surface oxygen groups, for both, hydrothermally synthesized and additionally carbonized materials. Raman analysis showed that the boron content does not affect a structural arrangement of the HTCB samples, and Raman structural parameters show a higher degree of disorder, compared to the CHTCB samples. Comparison of structural and surface characteristics of hydrothermal carbons and carbonized materials contributes to the study of the so far, insufficiently clarified influence that boron incorporation has on the material characteristics. © 2022 Serbian Chemical Society.

AB  - This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the influence of surface properties on hormone adsorption, chemical modification of ACCs with HNO3, HCl, or KOH was employed. Applied treatments increased the specific surface area and changed the content of oxygen functional groups. Increased content of acidic surface oxygen functionalities enhanced adsorption efficiency up to 30 % and had a more dominant influence on adsorption capacity than specific surface area. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data fitted well with the Freundlich isotherm model. Calculated mean sorption energy values of 1.4475, 1.3387, and 1.0541 kJ/mol, for E1, E2, and EE2 respectively, indicated that removal of selected hormones was dominated by physisorption mechanism. Obtained Langmuir adsorption capacities, 12.34, 12.66, and 11.11 mg/g for estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol, respectively, as well as convenience of manipulation, recommend activated carbon cloth modified with HNO3 as an efficient adsorbent for removing estrogen hormones from the water.

AB  - Resorcinol–formaldehyde (RF) cryogels were synthesized by sol–gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels in an inert atmosphere to 950 °C. Nitrogen doped CCs (CCN) were synthesized by introducing melamine into RF precursor mixture solution to obtain nitrogen concentration 2, 6 and 10 wt.%. Material was characterized by elemental analysis, nitrogen adsorption– desorption measurements, scanning electron microscopy (SEM), Raman spectroscopy, FT-IR Spectroscopy. Cyclic voltammetry (CV) was used to investigate capacitive and electrocatalytic properties. Conductivity measurement was also performed. Elemental analysis results confirmed presence of nitrogen in CCN samples in the range from 0.45 to 1.15 wt.%. Raman spectroscopy of the samples showed increase of D and G peak integrated intensity ratio (ID/IG) with nitrogen doping suggesting that the structural disorder as well as edge plane density increase, but according to similar ID/IG values for CCN samples, their share is not directly related to the amount of incorporated N. Characterization by nitrogen adsorption showed that overall specific surface and maximum mesopores are achieved in CCN sample with medium nitrogen concentration. Results of cyclic voltammetry experiments demonstrated maximum capacitance for CCN sample with smallest N wt.% indicating that narrow pore size distribution and high specific surface area are dominant factors to achieve good capacitive behavior. The relatively low doping level of nitrogen reached in CCN samples may be the reason for the incomplete reduction of oxygen to hydroxide and furthermore it turned out that presence of N in the structure of CC had a negligible effect on the otherwise relatively high conductivity of CC. © 2019 Elsevier B.V.

AB  - TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of obtained composites was performed by thermogravimetric analysis, scanning electron microscopy, nitrogen adsorption-desorption isotherms, X-ray diffraction, UV-Vis diffuse reflectance spectroscopy and Fourier transform infrared spectroscopy. The possibility of using TiO2/carbon composites as photocatalysts for UV assisted degradation of methylene blue in aqueous solution and selected pharmaceuticals from multicomponent solution was examined. It was found that increase in the glucose concentration, i.e. increased carbon content, leads to the higher porosity and increase in the share of photocatalytically active anatase phase in obtained TiO2/carbon composites. Sample obtained from the most concentrated glucose solution (TiO2/HTC4), showed the superior photocatalytic activity under UV irradiation toward both methylene blue and selected pharmaceuticals. In addition, TiO2/HTC4 show high recycling ability with degradation ratio of methylene blue higher than 81% after five cycles. Also, TiO2/HTC4 is expected to be a promising candidate for photocatalytic processes using visible light.

AB  - In this paper, pristine and chemically treated multi-walled carbon nanotubes (MWCNTs) were employed as solid-phase extraction sorbents for the isolation and enrichment of multi-class pharmaceuticals from the surface water and groundwater, prior to liquid chromatography-tandem mass spectrometry analysis. Thirteen pharmaceuticals that belong to different therapeutical classes (erythromycin, azithromycin, sulfamethoxazole, diazepam, lorazepam, carbamazepine, metoprolol, bisoprolol, enalapril, cilazapril, simvastatin, clopidogrel, diclofenac) and two metabolites of metamizole (4-acetylaminoantipyrine and 4-formylaminoantipyrine) were selected for this study. The influence of chemical treatment on MWCNT surface characteristics and extraction efficiency was studied, and it was shown that HCl treatment of MWCNT leads to a decrease in the amount of surface oxygen groups and at the same time favorably affects the efficiency toward extraction of selected pharmaceuticals. After the optimization of the SPE procedure, the following conditions were chosen: 50 mg of HCl-treated MCWNT as a sorbent, 100 mL of water sample at pH 6, and 15 mL of the methanol-dichloromethane mixture (1:1, v/v) as eluent. Under optimal conditions, high recoveries (79-119%), as well as low detection (0.2 to 103 ng L-1) and quantitation (0.5-345 ng L-1) limits, were obtained. The optimized method was applied to the analysis of five surface water and two groundwater samples, and three pharmaceuticals were detected, the antiepileptic drug carbamazepine and two metabolites of antipyretic metamizole.

AB  - Waste hemp (Cannabis sativa) fibers were used as sustainable and renewable raw materials for production of low-cost biocarbon sorbent for heavy metals removal. Carbon precursors of different chemical composition were obtained by oxidative and alkaline treatments of hemp fibers. Influence of lignocellulosic precursor chemical composition on hemp fibers-based biocarbon (HFB) characteristics was examined by BET surface area measurement, scanning electron microscopy and mass titration. It was found that lignin content and polymorphic transformation of cellulose increase the SBET of microporous HFBs, while hemicelluloses induce more homogeneous distribution of adsorption active sites. Heavy metal ions adsorption onto HFBs is primarily influenced by the amount of surface oxygen groups, while specific surface area plays a secondary role.

AB  - Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation by potassium hydroxide. Samples with considerably different surface and intrinsic micro-and mesoporous properties are obtained at different carbonization and activation conditions. The improvements of the capacitive properties are found upon increase in carbonization temperature, since it considerably influenced the specific surface area and the content of surface oxygen groups. Cyclic voltammetry experiments reveal the dependence of specific capacitance on the sweep rate due to the characteristic porous structure of the samples. The highest measured value in 1 M H2SO4 solution is 122 F g(-1). The electrochemical impedance data indicates eight-branch transmission line equivalent electric behavior of activated carbons.

AB  - In this work, a new carbon paste electrode, prepared from nitrogen-doped hydrothermal carbon (CHTCN) was applied for the electrochemical detection and determination of carbendazim fungicide. CHTCN samples with the nominal nitrogen content 0.05-0.5 wt. % in glucose precursor were prepared by simple, low-cost synthesis with the accompanying carbonization to 1273 K. The presence of nitrogen in CHTCN samples was confirmed by elemental analysis. Characterization of CHTCN as material for carbon paste electrode was achieved by cyclic voltammetry measurement of the Fe(CN)(6)(3-/4-) redox couple. The results showed that best electrochemical response was obtained from the sample with a nominal nitrogen concentration of 0.1 wt. % and with tricresyl phosphate as a binder. During the development of a differential pulse stripping voltammetric method for carbendazim determination applying new electrode, the following experimental parameters were studied: the sort and amount of binding liquid, the effect of pH, accumulation potential and accumulation time. Under optimal conditions, the electrode offered linearity in the wide concentration range from 25 to 490 ng cm(-3) and an estimated detection limit of 1.21 ng cm(-3). Moreover, the electrode showed good stability, high selectivity and satisfactory anti-interference ability. Finally, the developed method was successfully applied for the determination of carbendazim traces in spiked tap and river water samples.

AB  - Carbon cryogel/ceria composite, with 10 wt.% of ceria, was synthesized by mixing of ceria and carbon cryogel (CC). The sample was characterized by field emission scanning electron microscopy, nitrogen adsorption and X-ray diffraction. The adsorption of arsenic(III) ions from aqueous solutions on carbon cryogel/ceria nanocomposite was studied as a function of time, solution pH and As(III) ion concentration. The results are correlated with previous investigations of adsorption mechanism of arsenic(III) on carbon cryogel. Adsorption dose experiments showed that the mass of the adsorbent was reduced for 20 times, in comparison with pure CC, for the same amount of adsorbed arsenic(III) ions. BET isotherm was used to interpret the experimental data for modelling liquid phase adsorption.

abstract = "Carbon cryogel/ceria composite, with 10 wt.% of ceria, was synthesized by mixing of ceria and carbon cryogel (CC). The sample was characterized by field emission scanning electron microscopy, nitrogen adsorption and X-ray diffraction. The adsorption of arsenic(III) ions from aqueous solutions on carbon cryogel/ceria nanocomposite was studied as a function of time, solution pH and As(III) ion concentration. The results are correlated with previous investigations of adsorption mechanism of arsenic(III) on carbon cryogel. Adsorption dose experiments showed that the mass of the adsorbent was reduced for 20 times, in comparison with pure CC, for the same amount of adsorbed arsenic(III) ions. BET isotherm was used to interpret the experimental data for modelling liquid phase adsorption.",

AB  - Nanoemulsion technique, based on Ouzo effect, was applied for synthesis of the pure and silver doped (2.5 and 5 mol%) calcium hydroxyapatite (HAp). After calcination at 500 degrees C fully crystallized powders were obtained. X-ray powder diffraction analysis accompanied with Rietveld refinement revealed that the synthesized powders were single-phase hydroxyapatite. Raman spectroscopy also confirmed that the synthesized powders were single-phase. The obtained HAp particles were spherical in shape and their sizes were in the nanometer range which was revealed by field emission scanning electron microscopy analysis (FESEM). The successful synthesis of the single-phase Ag doped HAp showed that nanoemulsion method is a simple technique for obtaining pure and doped hydroxyapatite nanospheres.

AB  - Boron doped hydrothermal carbon microspheres were synthesized by introducing boric acid into glucose precursor solution to obtain boron concentration from 0.1 to 1 wt. %. Following hydrothermal treatment, samples were thermally treated to 1000 degrees C. For obtained samples structural and surface characterization were performed. Characterization of obtained samples as material for carbon paste electrode was achieved by measurement of the Fe (CN)(6)(3-/4-) redox couple and linuron determination. Catalytic effect of boric acid on hydrothermal reaction induced enlargement of particle size for boron doped samples. Significant reduction of specific surface area for samples with highest boron concentration was observed. Boron was substitutionally incorporated in the structure of doped samples and incorporation up to 0.6 wt. % in precursor solution generates structure ordering, which induces a reduction of surface active sites for oxygen adsorption in a greater extent. It was found that modified structural and surface characteristics are responsible for good electron transfer property of carbon paste electrode based on doped samples with nominal boron concentration range from 0.2 to 0.6 wt. %. However, it has been shown that sample with nominal boron concentration of 0.2 wt. % proved to be most promising candidate as a material for carbon paste electrode.

AB  - The new and simple approach for deposition of catalytically active TiO2 coating on carbon monolith (CM) carrier was presented. CM photocatalysts were impregnated with TiO2 using titanium solution and thermal treatment, and their photocatalytic activity was investigated in the process of methylene blue (MB) photodegradation. For the purpose of comparison, CM composite photocatalysts were prepared by dip-coating method, which implies binder usage. The presence of TiO2 on CM carrier was confirmed by Raman spectroscopy and scanning electron microscopy. The sorption characteristics of CM and the role of adsorption in the overall process of MB removal were evaluated through amount of surface oxygen groups obtained by temperature-programmed desorption and specific surface area determined by BET method. CM has shown good adsorption properties toward MB due to high amount of surface oxygen groups and relatively high specific surface area. It was concluded that photocatalytic activity increases with CM disc thickness due to increase of MB adsorption and amount of deposited TiO2. Good photocatalytic activity achieved for samples obtained by thermal treatment is the result of better accessibility of MB solution to the TiO2 particles induced by binder absence.

AB  - The main objective of this work was to find optimal production parameters for the preparation of activated hemp fibers (ACh) with good adsorption properties toward pesticides. In order to examine the role of manufacturing parameters on ACh surface characteristics, activation process of carbonized hemp fibers was investigated by temperature programmed reaction and evolved gaseous products of activation were monitored by mass spectrometry. ACh samples were characterized by BET surface area, scanning electron microscopy and temperature-programmed desorption. KOH activation induces the reduction of oxygen groups existing on the carbonized hemp fiber surface and the formation of the more stable, predominantly anhydride groups, while porosity development correlates with both H-2 and CO, evolved during the activation, and increases with carbonization and activation temperature. Finally, the highest efficiency in pesticides removal was achieved by carbonization of waste hemp fibers and activation at 900 degrees C with KOH/carbonized material ratio of 2/1. High efficiency in pesticides removal indicates that activated hemp fibers could be successfully used as a sorbent in water purification.

AB  - By varying the parameters of carbonization and activation, different samples of hemp fibers based activated carbon were obtained. Optimal production conditions were selected based on the adsorption properties of activated hemp fibers toward pesticides. Therefore, the influence of production conditions on the specific surface area, measured by dynamic method, and adsorption characteristics of activated hemp fibers toward different pesticides (acetamiprid, dimethoate, carbofuran and atrazine) was examined. Decrease of pesticide concentration, as a consequence of the adsorption, was determined by liquid chromatography-tandem mass spectrometry technique. Based on obtained results, an efficient pesticides sorbent can be produced using: carbonization temperature of 1000 oC, activated agent/carbon material ratio of 2/1 and activation temperature of 900 oC. Additionally, activated hemp fibers impregnated with silver proved to be suitable for water disinfection due to the strong antimicrobial activity against Escherichia coli, Staphylococcus aureus and Candida albicans.

AB  - Hemp (Cannabis sativa) was most likely the first plant cultivated by mankind for its textile use. Currently, the interest in hemp is focused on its use as a raw material for the production of environmentally friendly clothes, technical textiles and composite materials. The increased production of hemp fibers in textile industry brings the considerable amount of waste in the form of short and entangled fibers. The cost of waste disposal can be minimized by recycling the waste in the way of producing useful lowcost products. Following the general trend of finding low-cost and easily available adsorbent, waste short and entangled hemp fibers were utilized as a heavy metal biosorbents. Due to the specific structure and heterogenous chemical composition (cellulose, hemicelluloses, lignin, pectin), short hemp fibers as biosorbent offer an effective way to decrease Pb2+, Cd2+ and Zn2+ ion concentration in wastewaters. The influence of hemp fiber chemical composition on their heavy metal ions sorption potential, were assessed by evaluating the water and metal ions uptake capacities of differently modified hemp fibers. The process of heavy metal ions biosorption on short hemp fibers was clarified by mathematical model development. Proposed mathematical model provides a better insight into phenomena of different ions transport through porous fiber matrices, and possibility of optimization of the complex process of biosorption. This is from great importance in the case of using short hemp fibers as filter material for removing the heavy metal ions from polluted water. Furthermore, there is a growing interest in using different type of waste biomass for production of carbon materials as a sorbents for water purification. From that aspect, short and entangled hemp fibers were used as low-cost precursor for production of carbon materials. Chemical modification of hemp fibers, prior to carbonization, affects the specific surface area, amount of surface oxygen groups and morphology of carbonized hemp fibers. Furthermore, activation of carbonized materials with potassium hydroxide improves sorption properties of carbonized hemp fibers by increasing the specific surface area (up to 2192 m2/g) and amount of surface oxygen groups. Due to the good adsorption properties toward heavy metals and pesticides, carbonized and activated hemp fibers were successfully used as a sorbent for the purification of water polluted with pesticides and heavy metals. Also, activated hemp fiber sorbent used for analyte preconcentration in the solid-phase extraction procedure (SPE) for pesticide analysis in water samples, showed even higher efficiency in pesticides preconcentration than expensive commercial cartridges. Sorption process of heavy metal ions and structural parameters of carbonized hemp fibers were described by upgrading already proposed mathematical model. A good agreement between model prediction and the experimental data indicates that the proposed mathematical model can be used for optimization of heavy metal ions adsorption process by correlating the model parameters to the carbonized hemp fibers performances.

AB  - Carbonized hemp fibers obtained by carbonization of origin and chemically modified waste hemp fibers was used as a low-cost sorbent for heavy metals removal. The efficiency of carbonized hemp fiber samples as a sorbent was tested through the adsorption of lead ions as a heavy metal model ion. Although changes in carbon precursor structure, induced by chemical modification, affect the sorption process and sorption capacity of carbonized hemp fibers, all carbonized hemp fibers samples show good adsorption properties toward lead ions. Obtained experimental data was used for development of the mathematical model that describes both the phenomenon of metal ions transport through the porous sorbent matrices, and the structure of carbonized hemp fibers. Effective diffusion coefficient, damping coefficient and the lead ion concentration profile within the carbonized hemp fibers, obtained as results of proposed mathematical model, give the insight in the mechanism and the rate of adsorption process, while average tortuosity connected the sorbent structure and ions transport through the sorbent. A good agreement between model prediction for both structural and ion transport model parameters and the experimental data, indicates that the proposed mathematical model can be successfully used for optimization of heavy metal ions adsorption process by correlating the model parameters to the carbonized hemp fibers performances.

AB  - The capacity of carbon monolith for pesticide removal from water, and the mechanism of pesticide interaction with the carbon surface were examined. Different carbon monolith samples were obtained by varying the carbonization and activation parameters. In order to examine the role of surface oxygen groups on pesticide adsorption, the carbon monolith surface was functionalized by chemical treatment in HNO3, H2O2 and KOH. The surface properties of the obtained samples were investigated by determination of the Brunauer, Emmett and Teller (BET) surface area, pore size distribution and temperature-programmed desorption. Adsorption of pesticides from aqueous solution onto the activated carbon monolith samples was studied using five pesticides belonging to different chemical groups (acetamiprid, dimethoate, nicosulfuron, carbofuran and atrazine). The presented results show that higher temperature of carbonization and amount of activating agent enable microporous carbon monolith with higher numbers of surface functional groups to be obtained. The adsorption properties of the activated carbon monolith were more readily affected by the number of surface functional groups than by the specific surface area. Results obtained after carbon monolith functionalization showed that π - π interactions were the driving main force for adsorption of pesticides with an aromatic structure, while acidic groups played an important role in adsorption of pesticides with no aromatic ring in their chemical structure.

AB  - In modern medicine implants are very important and so is their design and choice of materials. Almost equally important is the choice of imaging technique used to in vivo monitor their fate and biocompatibility. The aim of this study was to evaluate the ability of magnetic resonance imaging (MRI) in monitoring the biocompatibility of two newly designed carbon fibers. We have analyzed the interaction of surface functionalized carbon fibers (basic and acidic) with muscle and subcutaneous tissues of rabbits. MRI techniques showed to be useful in longitudinal monitoring of the surrounding tissues, assessment of biocompatibility of new implants, and in the distinction of in vivo surgical edema from inflammation. Histopathology confirmed MRI results, thus showing that MRI has a great potential for in vivo studies of such materials.
AB  - U modernoj medicine implanti su veoma važni, kao i njihovo dizajniranje i izbor materijala. Isto tako je značajan i izbor tehnike kojom se prati in vivo njihova sudbina i biokompatibilnost. Cilj ove studije je bila procena mogućnosti praćenja biokompatibilnosti dva novo dizajnirana karbonska vlakna pomoću magnetic resonance imaging (MRI). Analizirali smo interakciju karbonskih vlakana sa funkcionalizovanom površinom (kiselinom i bazom) sa mišićnim i potkožnim tkivom kunića. MRI tehnika se pokazala uspešnom u toku praćenja reakcije okolnog tkiva, i procene biokompatibilnosti nove vrste implanata, jer je uspela da in vivo odvoji hirurški edem od inflamacije. Patohistološka analiza je potvrdila rezultate MRI pokazujući time da MRI ima veliki potencijal za in vivo studije takvih materijala.

MRI techniques showed to be useful in longitudinal monitoring of the surrounding tissues, assessment of biocompatibility of new implants, and in the distinction of in vivo surgical edema from inflammation. Histopathology confirmed MRI results, thus showing that MRI has a great potential for in vivo studies of such materials., U modernoj medicine implanti su veoma važni, kao i njihovo dizajniranje i izbor materijala. Isto tako je značajan i izbor tehnike kojom se prati in vivo njihova sudbina i biokompatibilnost. Cilj ove studije je bila procena mogućnosti praćenja biokompatibilnosti dva novo dizajnirana karbonska vlakna pomoću magnetic resonance imaging (MRI). Analizirali smo interakciju karbonskih vlakana sa funkcionalizovanom površinom (kiselinom i bazom) sa mišićnim i potkožnim tkivom kunića. MRI tehnika se pokazala uspešnom u toku praćenja reakcije okolnog tkiva, i procene biokompatibilnosti nove vrste implanata, jer je uspela da in vivo odvoji hirurški edem od inflamacije. Patohistološka analiza je potvrdila rezultate MRI pokazujući time da MRI ima veliki potencijal za in vivo studije takvih materijala.",

AB  - There is a growing interest in utilization of abundantly available materials, bio-mass or industrial byproducts, as precursors for the preparation of carbon materials. Short hemp fibers, acquired as waste from textile production, were used as low-cost precursor for production of carbon materials as a sorbent in the solid-phase extraction, for pesticide analysis in water samples. Different carbon materials were prepared by carbonization of unmodified and chemically modified hemp fibers. Activation of carbonized materials with potassium hydroxide improves sorption properties of carbonized hemp fibers by increasing the specific surface area (up to 2192 m(2)/g) and the amount of surface oxygen groups. The following parameters that may affect the solid-phase extraction procedure efficiency were optimized: different elution solvents and the pH value of pesticide solution. Extracts were analyzed by liquid chromatography-tandem mass spectrometry technique. For this study pesticides belonging to the different chemical classes were chosen. Obtained results indicate that carbonized and activated hemp fibers could be successfully applied as a solid-phase sorbent for the pesticide analysis in water samples.

AB  - Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron and atomic force microscopy. Structural changes were monitored by Raman spectrometry, while changes of wettability and the content of surface oxygen complexes were examined by contact angle measurements and temperature programmed desorption. Elastic recoil detection analysis was applied for determination of hydrogen concentration profiles in irradiated samples. Cyclic voltammetry was used for the assessment of the electrochemical properties of modified glassy carbon electrodes. It was concluded that there is critical fluence range (2 x 10(17)-5 x 10(17) ion cm(-2)) inside of which significant changes of glassy carbon properties occur.

AB  - We report a particular method of Pt/glassy carbon (GC) surface formation, based on a 15 key H(+/-) ion beam irradiation of thin H(2)PtCl(6)xnH(2)O layer placed over the GC surface. Hydrogen-ion beam irradiation provided an excellent adherence of Pt deposit, unlike to any other Pt-deposition method. Furthermore, the morphology and electrochemical activity of GC/Pt catalyst obtained at the fluence of 5 x 10(17) cm(-2) was found to be sensitive to the sign of charge of hydrogen ions. The electrochemical activity of such obtained Pt/GC surface toward oxygen reduction and ethanol oxidation was compared with the activity of the Pt deposits obtained by other more common reduction procedures.

AB  - Boron was introduced into glassy carbon by chemical modification and by irradiating the precursor polymer with boron ions. Using chemical modification, a polymer with uniform distribution of boron in the bulk was obtained, whereas irradiation with B3+ produced a polymer with boron located in a narrow region under the surface. Following modification with boron, the samples were carbonized at 1273 K and examined using X-ray diffraction, Raman spectroscopy, temperature programmed desorption (TPD) and by hardness measurements. Structural analysis results suggest that boron is mostly substitutionally bonded in the glassy carbon structure regardless of the method used to introduce boron into the polymer precursor. Formation of crosslinks between glassy carbon ribbons during carbonization as a consequence of the recombination of ion beam induced changes in the polymer structure and a high concentration of boron in the subsurface layer is proposed to account for an increase of glassy carbon hardness. An increase in the total amount of surface oxygen groups was observed in the TPD spectra of both boron-modified samples due to an increase in the number of active sites. Results show that the nature of these sites is influenced by the initial distribution of boron in the polymer precursor. (C) 2011 Elsevier Ltd. All rights reserved.
