AB  - A novel self-supporting carbon thin film flexible supercapacitor electrode with high volumetric and areal capacitance was developed. The increase in capacitance performance is achieved by introducing channels across the carbon thin film using ion-track technology. In the first step of the electrode synthesis, latent tracks are inscribed in the starting polyimide (Kapton) foil by irradiation with 253 MeV Kr ions. Next, macropores in the form of cylindrical channels are formed by selective chemical etching with NaOCl along the ion tracks, creating ion-track polymer. With subsequent carbonization and activation of the ion-track polymer, activated ion-track carbon is produced. A range of samples are obtained by varying the chemical etching time of the irradiated polymer. In addition to channel formation the chemical etching time influences the composition of surface functional groups. The best results are obtained by chemical etching for 40 min, the thickness of the sample is 21 A mu m with channel density 2.4 x 10(6) cm(-2) and average channel diameter 430 nm. Beside cylindrical macro channels this material is mainly microporous with 0.62 nm pore diameter and shows the highest areal (494 mF/cm(2)), volumetric (224 F/cm(3)) and gravimetric (178 F/g) capacitance. As a consequence of channel formation, the rate capability of the supercapacitor was also increased.

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. Equilibrium data obtained for lead ions adsorption were analyzed by different nonlinear adsorption isotherms, and the best fitting model was chosen using standard deviation and Akaike information criterion (AIC(C)). The maximum adsorption capacities of HFBs ranged from 103.1 to 116.3 mg Pb/g. Thermodynamic parameters showed that Pb2+ adsorption onto HFBs is a spontaneous and complex endothermic process, suggesting the coexistence of physisorption and chemisorption mechanisms.

The  possibility  of using   TiO2/HTC   as   photocatalysts   for   UV   and   visible   light   assisted degradation  of  methylene  blue  inaqueous  solution  was  examined.  It  was found  that  carbon  presence  in  TiO2/HTC  leads  to  the  higher  porosity  and increase in the share of photocatalytically active anatase phase. Compared to the   hydrothermally   synthesized   TiO2,   TiO2/HTC   showed   the   superior photocatalytic  activity  under  UV  irradiation.  In  addition,  TiO2/HTC  show high  recycling  ability  with  degradation  ratio  of  methylene  blue  higher  than 81%  after  five  cycles.  Also,  TiO2/HTC  is  expected  to  be  a  promising candidate for photocatalytic processes using visible light.

AB  - A systematic ab initio (DFT-GGA) study of adsorption of various oxygen species on graphene has been performed in order to find out general trends and provide a good starting point to analyze the oxidation of more complex carbon materials. Particular attention was paid to finding an appropriate supercell model. According to our findings, atomic O is characterized by stable adsorption on graphene and very strong adsorption on defective graphene. On the other hand, O-2 does not adsorb on graphene and is allowed to diffuse freely to the defect, where it is expected to dissociate into two strongly adsorbed O atoms. The obtained results were compared with available theoretical data in the literature and good agreement was achieved.

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. (C) 2015 Elsevier Inc. All rights reserved.

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  - 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. (C) 2015 Elsevier Ltd.

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 effect of platinum catalyst on the thermally activated healing of defects produced in a graphene-ribbon network by irradiating glassy carbon with a 15 key hydrogen-ion beam has been investigated by Raman spectrometry. The platinum has been incorporated into glassy carbon by hydrogen-ion beam irradiation of a thin layer of platinum salt deposited on the glassy carbon surface. The presence of platinum is beneficial because it becomes incorporated by ion-beam mixing and facilitates the structural healing of the amorphous subsurface layer by decreasing the healing temperature from 500 degrees C to 270 degrees C in comparison to irradiated glassy carbon that contains no platinum. In the case of chemically doped platinum in glassy carbon the in-plane structural ordering, demonstrated by the decreasing I-D/I-G ratio, is a linear function of the platinum added to the phenol-formaldehyde resin as precursor. The results of the density functional theory calculations showed that platinum mediates the reorganization of the bond network and the removal of defects present in the graphene layer.

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 pi-pi 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  - The incorporation of boron into glassy carbon was achieved by irradiating two different types of targets: glassy carbon polymer precursor and carbonized glassy carbon. Targets were irradiated with a 45 keV B3+ ion beam in the fluence range of 5 x 10(15)-5 x 10(16) ions cm(-2). For both types of targets, the implanted boron was located in a narrow region under the surface. Following irradiation, the polymer was carbonized under the same condition as the glassy carbon samples (at 1273 K) and examined by Raman spectroscopy, temperature programmed desorption, hardness and cyclic voltammetry measurements. Structural analysis showed that during the carbonization process of the irradiated polymers, boron is substitutionally incorporated into the glassy carbon structure, while for irradiated carbonized glassy carbon samples, boron irradiation caused an increase of the sp(3) carbon fraction, which is most pronounced for the highest fluence irradiation. Further analyses showed that different nature of boron incorporation, and thus changed structural parameters, are crucial for obtaining glassy carbon samples with modified mechanical, chemical and electrochemical properties over a wide range.

AB  - Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and 25 gm. Pore formation during the activation process progresses in two steps due to the existence of a denser surface layer and a more porous core material. In the first step micropores are opening in the dense surface region of the material with average pore diameter smaller than 1 nm. During the second step, mesopores start opening, while micropore volume remains constant with the average micropore diameter of over 1 nm, producing bimodal texture. The first step finishes after 30 min for the thinner samples while for the thicker samples it finishes after 60 mm of activation. As a consequence of such textural changes during activation, the thicker sample has a maximum areal capacitance of 0.35 F/cm(2). The thinner sample activated for 30 min has a maximum volumetric capacitance of 220 F/cm(3) and achieves a maximum gravimetric capacitance of 240 F/g when the texture becomes bimodal after 240 min of activation. These results confirm that activation of carbonized Kapton films gives promising electrode materials for supercapacitors. (C) 2013 Elsevier Ltd. All rights reserved.

AB  - In this study the application of home-made unmodified (GC) and bulk modified boron doped glassy carbon (GCB) electrodes for the voltammetric determination of the linuron was investigated. The electrodes were synthesized with a moderate temperature treatment (1000A degrees C). Obtained results were compared with the electrochemical determination of the linuron using a commercial glassy carbon electrode (GC-Metrohm). The peak potential (E (p) ) of linuron oxidation in 0.1 mol dm(-3) H2SO4 as electrolyte was similar for all applied electrodes: 1.31, 1.34 and 1.28 V for GCB, GC and GC-Metrohm electrodes, respectively. Potential of linuron oxidation and current density depend on the pH of supporting electrolyte. Applying GCB and GC-Metrohm electrodes the most intensive electrochemical response for linuron was obtained in strongly acidic solution (0.1 mol dm(-3) H2SO4). Applying the boron doped glassy carbon electrode the broadest linear range (0.005-0.1 A mu mol cm(-3)) for the linuron determination was obtained. The results of voltammetric determination of the linuron in spiked water samples showed good correlation between added and found amounts of linuron and also are in good agreement with the results obtained by HPLC-UV method. This appears to be the first application of a boron doped glassy carbon electrode for voltammetric determination of the environmental important compounds.

AB  - Intermetallic compound TiFe, known for its hydrogen storage applications, is modified by substituting iron by nickel and related changes of properties and applicability of the obtained compounds are studied. Samples TiFe1-xNix (x = 0.2-0.6) are synthesized by melt-spinning and their crystal structure, desorption characteristics and electronic structure are investigated by TPD, H-1 NMR and Mossbauer spectroscopy. State-of-the-art DFT calculations give further insight into the changes in electronic structure and bonding related to the hydrogen absorption and substitution of iron by nickel. The increase of Ni/Fe ratio in the TiFe1-xNix is found to result in the increase of hydride cohesive energies and in the systematic shifting of Fermi energy (E-F) to lower values, in both pure intermetallics and appropriate hydrides. Hydride formation was found to influence the Fermi energy lowering and the increase of number of states at E-F.

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  - 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. (C) 2012 Elsevier B.V.

AB  - The carbon/carbon (C/C) composite with satisfactory mechanical properties were obtained through introduction of partially carbonized fibers as a precursor. Applying this procedure the production cost of C/C composites may be significantly reduced. Stabilized PAN fibers were partially carbonized at temperatures ranging from 400 to 1000 degrees C and reinforced with phenolic resin, resole type. Cured composite were carbonized up to 1000 degrees C in an inert atmosphere. Monofilament tensile test strength, Youngs modulus and tensile strength of partially carbonized fibers were determined. Mechanical properties of carbon/carbon composites (flexural strength and flexural modulus) determined by using three-point bending test. The effect of partially carbonized fibers on the mechanical properties of C/C composites was examined by scanning electron microscope (SEM) through analysis of the fracture surface. The C/C composite reinforced with partially carbonized fibers at 600 degrees C showed quite satisfactory flexural strength. This confirms assumptions that through co-carbonization of partially carbonized fibers and resin C/C composite with suitable mechanical properties could be obtained. (C) 2011 Elsevier B.V.

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.

AB  - The surface characteristics of different carbon materials: activated carbon, carbon felt, glassy carbon and a porous carbon monolith were investigated. The specific surface area was examined by the BET method with N(2) adsorption, the amount and the type of surface oxygen groups by Boehm titration as well as by temperature-programmed desorption (TPD). By comparing the results obtained using BET analysis with those of TPD and the Boehm method, it was found that the number of surface groups was not proportional to the specific surface area. The total amount of oxygen groups, obtained by TPD, is higher than the amount obtained by Boehms method for porous samples. The inconsistencies between these results originate from the fact that the Boehm method is limited to the determination of acidic and basic groups, whereas TPD provides information on the total number of all surface oxygen groups. In addition, the presence of porosity could reduce the solvent-accessible surface in the Boehm method. The TPD profiles of CO evolution showed the presence of a low temperature maximum, below 650 K, which originates from CO(2) reduction on the carbon material surface.

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  - 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. (C) 2011 Elsevier Ltd.
