AB  - The human health risks of cadmium (Cd), lead (Pb), and nickel (Ni) in fifty regular and slim cigarette brands available in the Serbian market were evaluated. Distributions on per-cigarette basis concentrations of these metals, as determined by graphite furnace atomic absorption spectrometry, were used as inputs in the probabilistic risk assessment. The contents of these metals in cigarettes varied significantly. Larger quantities of the studied metals were observed in regular cigarettes than in slim cigarettes, but the concentration levels per cigarette tobacco mass were higher in slim cigarettes. The metal concentrations in counterfeit cigarettes were marginally higher than those in authentic brands. Based on the mean concentrations, Pb was the most abundant toxic metal, followed by Ni and Cd. The calculated values of the cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR) indicated a low noncarcinogenic risk and low but not negligible carcinogenic risk from Cd, Pb, and Ni. The mean HI and ILCR values obtained using probabilistic and deterministic approaches were similar. A Monte Carlo simulation was employed to minimize the uncertainty of health risk estimation. The sensitivity analysis revealed that the most influential factor was cigarette mass followed by Cd content.

AB  - The subject of this work is synthesis and characterization of pectin-based cryogels obtained by internal crosslinking with calcium ions. The crosslinking reaction was confirmed by FTIR/ATR analysis, while SEM analysis demonstrated that pores of obtained cryogel were in macro range (between 130 and 380 µm). Pectin cryogel had high swelling degree with the value of 800% after 24 h of immersion in distilled water, and high water vapor permeability (E-7 order, g/ m s Pa). In addition, it showed high rate of biodegradation (85%) after exposure of 3 months in the soil. The obtained results suggest that pectin cryogel obtained by internal crosslinking reaction might find applicable potential in food, agriculture and separation technologies, providing an eco-sustainable approach to tackle current ecological and economical stresses.

AB  - Citrus fruits are widely consumed around the world and among them grapefruit (Citrus paradisi macfad) stands out with its characteristic appearance and flavor. The fruit is growing on a tree that belongs to Rutaceae family and its positive contribution to health is attributed to phytochemicals found in it. The phytochemicals have the key role in mediating oxidation process because they act as antioxidants and by that prevention of cell damage, reducing the risks of many diseases, boosting of the immune system, balancing hormone levels, and notable antibacterial and antiviral response of the organism happens. Grapefruits contain several phytochemicals including: carotenoids, flavonoids (naringin), limonoids, organic acids, pectin, and folate. Considering the worldwide consumption and popularity in everyday diet of grapefruit, the antioxidant activity of its extracts is determined in this paper. Weighed amount 10 g of fresh grapefruits was added to a mixture consisting of organic solvents (hexane, acetone, and ethanol in volumes ratio 2:1:1, respectively) and 0.05% (w/v) butylated hydroxytoluene. The mixture was stoppered and mixed on an orbital shaker at 180 rpm for 15 minutes. The temperature during the mixing was kept at 5 °C in the water bath. Afterward, 7.5 ml of cold deionized water on every 10 grams of starting sample was added to the mixture and agitated for another 5 min. The suspension was transferred to a separation funnel to separate the upper (non-polar) from the lower (polar) phase for 10 minutes at room temperature. The polar phase was subjected for antioxidant capacity determination by ABTS, DPPH, FRAP and CUPRAC methods. The results for the applied methods expressed per kg of the sample are: 1.8 mmol∙kg-1, 0.72 mmol∙kg-1, 9.7 μmol∙kg-1, 4.66 mmol∙kg-1, respectively. The obtained results are recommending grapefruit as a potent source of phytochemicals with antioxidant properties.

AB  - This work provides an insight into the nutritional quality of Hector-F1 tomato (Solanum lycopersicum L.) fruit grown in Serbia and the juice prepared from it regarding the contents of carotenoids, flavonoids and polyphenols as compounds beneficial for a healthy diet. Initially, ultra-high performance liquid chromatography with electrospray ionization mass spectrometry (UHPLC-ESI-MS) was employed for both polar and non-polar tomato extracts to identify compounds present in the samples. Then, lycopene, β-carotene, total polyphenols and flavonoids contents were determined by means of ultraviolet-visible (UV-Vis) spectrophotometry. To evaluate the antioxidant activity of the samples, four methods were applied, namely, the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) method, 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, the ferric ion reducing antioxidant power (FRAP) method and the cupric ion reducing antioxidant capacity (CUPRAC) method. In addition, the antimicrobial potential was tested against gram-positive bacteria, gram-negative bacteria and the yeast Candida albicans. The thermal treatment in all cases modified the chemical composition of tomato as demonstrated by a decrease in values of all measured parameters. This comprehensive analysis provided data applicable to profiling and comparing cultivars grown in different geographical regions. © 2022 National Agricultural and Food Centre (Slovakia).

AB  - Two novel types of electrochemical sensors were obtained by chemical deposition of Pt and MoO2 nanoparticles onto multi walled carbon nano tubes (MWCNT) and used for determination of frequently used pesticides clomazone and oxyfluorfen in aqueous media via differential pulse stripping voltammetry (DPSV). Clomazone was determined in 0.1 M phosphate buffer solution at pH 7.0 in the concentration range 0.61-20.56 ng cm-3, with LOQ = 0.61 and LOD = 0.38 ng cm-3. Oxyfluorfen was determined with good reproducibility (RSD <2.4%) in the concentration range 2.5-34.5 ng cm-3, with r = 0.99 and a LOQ of 1.5 ng cm-3. Results were in the same range measured by HPLC/DAD, which was used as comparative method. Structural characterization of the dopped MWCNT performed by Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron (HR-TEM), and X-ray crystallography revealed a preserved MWCNT structure decorated with well dispersed species of the platinum and MoO2 nanoparticles.

AB  - A glassy carbon electrode was functionalized by MoO2 nanoparticle–decorated multiwalled carbon nanotubes (MWCNTs) and examined as a working electrode in oxyfluorfen (OXY) detection by differential pulse stripping voltammetry (DPSV). Measurement parameters were as follows: initial potential − 0.1 V, end potential + 0.5 V, accumulation potential − 0.15 V, accumulation time 80 s, and scan rate 50 mV s−1. A stripping potential of + 0.315 V vs. Ag/AgCl was employed. The pPesticide oxyfluorfen was determined in model samples by DPSV with good reproducibility (RSD <2.4%) in the concentration range 2.5 to 34.5 ng mL−1, with r = 0.99 and a limit of detection of 1.5 ng mL−1. These results are in the same range as those of HPLC/DAD, which is used as the comparative method. Recovery for OXY determination in a real river water sample was 102%. Analyses in Briton-Robinson buffer has shown to be pH dependent with the best response at pH 6.0.

abstract = "A glassy carbon electrode was functionalized by MoO2 nanoparticle–decorated multiwalled carbon nanotubes (MWCNTs) and examined as a working electrode in oxyfluorfen (OXY) detection by differential pulse stripping voltammetry (DPSV). Measurement parameters were as follows: initial potential − 0.1 V, end potential + 0.5 V, accumulation potential − 0.15 V, accumulation time 80 s, and scan rate 50 mV s−1. A stripping potential of + 0.315 V vs. Ag/AgCl was employed. The pPesticide oxyfluorfen was determined in model samples by DPSV with good reproducibility (RSD <2.4%) in the concentration range 2.5 to 34.5 ng mL−1, with r = 0.99 and a limit of detection of 1.5 ng mL−1. These results are in the same range as those of HPLC/DAD, which is used as the comparative method. Recovery for OXY determination in a real river water sample was 102%. Analyses in Briton-Robinson buffer has shown to be pH dependent with the best response at pH 6.0. Structural characterization of MoO2-MWCNT by Raman spectroscopy, field emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray crystallography revealed a preserved MWCNT structure decorated with firmly attached clusters of MoO2 nanoparticles.",

AB  - A simple and facile hydrothermal methodology for preparation of carbon microspheres supported with silver or platinum is presented. Electrocatalytic properties of modified carbon microspheres are tested against the electrochemical reduction reaction of hydrogen peroxide. As revealed by transmission electron microscopy, silver and platinum are immobilized on the surface of carbon microspheres in a form of nanoparticles. In addition, scanning electron microscopy reveals coexistence of smooth surface spherical-shaped carbon microspheres together with clusters that resemble a bunch-of-grapes. Carbon paste electrodes in combination with cyclic and square-wave voltammetry are used to study electrocatalytic properties of carbon microspheres. Voltammetric data are analyzed in light of the theory for simple irreversible electrode reaction. Correlation between experimental and theoretical data implies the highest electrocatalytic effect in the case of silver-modified carbon microspheres, though the electrode mechanism is more complex than theoretically predicted. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - Novel electrochemical sensor based on Pt supported multiwalled carbon nanotubes is used for determination of pesticide clomazone in aqueous media via differential pulse stripping voltammetry (DPSV). Since clomazone is stable and readily soluble in water, it is often found in water sources. Hence, its determination in the environment is of utmost importance. Herein, clomazone is determined in 0.1 M phosphate buffer solution at pH 7.0 in the concentration range of 0.61–20.56 ng cm−3, with LOQ = 0.61 and LOD = 0.38. These results are in the same range with HPLC/DAD, which is used as comparative method. It is shown that DPSV is a facile and efficient way for determination of clomazone in contrast to precise but field-impractical HPLC. Mechanistic approach in explaining electrode processes is correlated to structural aspects of the synthesized sensor. HRTEM data reveals a uniform distribution of Pt nanoparticles on the MWCNT support as a source of crucial, structural and electronic changes. Furthermore, characterisation of Raman results indicates the existence of structural defects, which is believed to be the leading reason for improvement in sensing response. © 2019 Taiwan Institute of Chemical Engineers

AB  - The incorporation of trace amounts (<0.2%) of Co and Ni noticeably enhanced the catalytic activity of nitrogen-free ordered mesoporous carbon (OMC) towards oxygen reduction reaction (ORR). (Co,Ni)-doped OMCs were characterized by N2-adsorption measurements, X-ray powder diffraction, field emission scanning electron microscopy and Raman spectroscopy methods, and their ORR activity was estimated by voltammetry on rotating disk electrode in acidic and alkaline media. (Co,Ni)-doped OMCs show modest activities in acidic media, while the catalytic activity in alkaline media is rather high. The measured activities are compared to the Pt-based and Pt-free ORR catalysts reported in the literature. The number of electrons consumed per O2in metal-doped OMCs was found to vary between 2 and 4, which is advantageous in comparison to metal-free OMC. Also, the mass activities of metal-doped OMCs were found to be up to 2.5 times higher compared to that of metal-free OMC. We suggest that the ORR activity is governed by a balance between (i) textural properties, which determine the electrochemically accessible surface of the catalyst and which are influenced by the addition of a metal precursor, and (ii) novel active sites formed upon the introduction of metals into the carbon structure. In particular, our Density Functional Theory calculations suggest that Co and Ni atoms embedded into the single vacancies of graphene can activate the O2molecule and contribute to the decomposition of peroxide.

AB  - The shell of Lagenaria vulgaris (LV) plant was used as biosorbent for strontium removal from aqueous solutions. Chemical structure of the biosorbent's surface was characterized by the means of FTIR and Boehm's titrations. SEM-EDX technique was used to study the morphology and elemental composition of the material. The analyses pointed out to abundance of acidic functional groups which are charged in solution and hence responsible for ionic exchange of Sr(II) ions. Sorption was examined by varying initial concentrations of Sr(II) in solutions, sorbent's loadings, pH, and contacting times. Equilibrium of the process was attained in the first 10 min of contacting and followed pseudo-second order and Chrastil's kinetic models. It was established that sorption onto aLVB was heterogenous by nature and fitted well to Freundlich and Sips isotherm models with maximum sorption capacity of 29.55 mg g(-1). Sorption potentail was kept high after six cycles when acidic desorbents were used.

AB  - Three types of functional ceramic composites were designed, synthesized and probed for effective sulfide removal from aqueous solutions. The main goal was to examine complex influence of graphite, surpluses of Fe (similar to 4%) and micro-additions of Cu (similar to 0.2%) on the functional features of the composites. The structural, textural, morphological and surface characteristics of the composites were examined in detail by XRD, nitrogen sorption, SEM and FTIR. It has been shown that all composites are solid heterogeneous systems containing amorphous and crystalline phases (graphite, hematite, montmorillonite, quartz, etc.) with pronounced redox activity in contact with sulfide aqueous solutions. Great enhancment of sulfide consumption was detected for composites which contained graphite and it was established that reaction kinetics is fitted to irreversible second-order batch reaction with two reactants. After the treatment of 1 mM S2- solution, using composite dossage of 1 g/dm(3), concentration dropped down to 0.02 mM. In addition, cyclic voltammetry at 50 mV/s revealed the key role of dopants in electrochemical aspect of the process. Obvious boost of S2- uptake is ascribed to numerous electrochemical, chemical and sorption processes on the composite's developed surface.

AB  - The physicochemical modification of peat through thermal and oxidation processes was carried out, in order to obtain new, inexpensive and active material for purification of different types of waters. During the modification, surface chemical compounds of Shilov type were formed. Batch adsorption properties and suitability of physicochemically modified peat (PCMP) for odor removal were tested in aqueous solutions of H2S and colloidal sulphur. Additionally, PCMP was tested in the removal of As(V) which is hazardous ingredient in contaminated waters. Possible mechanisms of pollutants binding include interactions, which lead to formation of adducts and clathrates. All these processes are elucidated in detail. The results showed that the obtained material can be used for the removal of sulphide, colloidal sulphur and As(V) from different types of waters.

abstract = "The physicochemical modification of peat through thermal and oxidation processes was carried out, in order to obtain new, inexpensive and active material for purification of different types of waters. During the modification, surface chemical compounds of Shilov type were formed. Batch adsorption properties and suitability of physicochemically modified peat (PCMP) for odor removal were tested in aqueous solutions of H2S and colloidal sulphur. Additionally, PCMP was tested in the removal of As(V) which is hazardous ingredient in contaminated waters. Possible mechanisms of pollutants binding include interactions, which lead to formation of adducts and clathrates. All these processes are elucidated in detail. The results showed that the obtained material can be used for the removal of sulphide, colloidal sulphur and As(V) from different types of waters.",

AB  - Electrochemistry of carbon paste electrode which contained serpentinite powder and graphite in 1:1 weight ratio was examined in three-electrode cell regarding its electrocatalytic and sensing properties. For this purpose, red-ox reactions of potassium ferrocyanide in aqueous solutions as benchmark media and pesticide tebufenozide (TBF) were examined. Serpentinite characterization performed by XRPD, SEM/EDX, and FTIR confirmed the structure typical for this mineral rock. Voltammetric analyses have in all cases shown that serpentinite modified carbon paste electrode (S-CPE) possess superior electrocatalytic activity in contrast to bare CPE for the red-ox reactions of K-4[Fe(CN)(6)]. The enlargement of the peak currents, higher electroactive surface area, and the decline of the peak-to-peak separation are a proof of reversible and faster electron transfer kinetics for S-CPE. The effect of pH on the electrochemical behaviour of TBF was investigated in Britton-Robinson buffer solutions in range from 2.0 to 7.0 and showed the best analytical performance at pH 5.0. The oxidation peak of TBF appeared at + 0.5 V vs. Ag/AgCl under conditions optimized for the determination of TBF in the differential pulse stripping voltammetry: initial potential + 0.1 V, end potential + 0.9 V, accumulation potential -0.35 V, accumulation time 120 s, and the scan rate 50 my s(-1).

AB  - Practical aspects of Lagenaria vulgaris shell conversion to activated carbon were examined along with its use in ranitidine adsorption. Kinetics and isotherms of adsorption onto Lagenaria vulgaris carbon (LVC) were correlated to several theoretical adsorption models. The best fit was found in the case of Langmuir and pseudo-second-order model indicating monolayer adsorption. The influence of pH under kinetic study showed slightly hindered adsorption below pH 4. The optimal adsorbent dosage was set to 1 g/L. LVC was characterized by several complementary techniques, including wet chemical techniques such as Boehms titrations and determination of pH(pzc) and pH of LVC, which revealed neutral nature of the adsorbent. N-2 sorptometry determined specific surface area of 665 m(2)/g and significant ratio of micropores in the sample with maximum walls diameter of 2.2 nm. Fourier transform infrared spectroscopy (FTIR) confirmed the role of lignin and cellulose in the formation of the final LVC structure. Porous structure of the material was proved by using scanning electron microscopy. Preparation of LVC material drew attention as an easy and low-cost process for production of a highly efficient adsorbent which exhibited fast kinetics of ranitidine removal in the first minutes of contacting and large adsorption capacity (315.5 mg/g) at equilibrium.

AB  - Serpentinite rock collected near Kopaonik Mountain in Serbia is considered as a multiphase assemblage mostly consisting of mineral lizardite. Forsterite has been obtained by chemical-thermal treatment of grounded sample of serpentinite. Electrochemical features of these two materials were investigated by using modified carbon paste electrode (CPE) which included mixing analytes, graphite powder and parafin oil as a binder and packing the mixture in a Teflon holder. Morphological and structural characteristics of the samples were analyzed by SEM and XRD techniques which revealed presence of certain crystal phases and agregates of irregular shapes sized from 10 to 40 μm. Cyclic voltammetry was employed to study their electrochemical characteristics. The peak current height and peak-to-peak separation showed that the electrochemical reaction is quasi-reversible. Kinetic parameters were derived from Tafel analysis. Calculated kinetic parameters indicated prominent electrocatalytic effect of the minerals for ferri/ferro cyanide redox reaction in aquaeous solution

AB  - Interaction of a TEA CO2laser, operating at 10.6 μm wavelength and pulse length  of  100  ns,  with titanium  target  (implant),  in  nitrogen  and  carbon-dioxide  gas  ambience  was  studied.  The  Ti-surface  modifications  were studied  at  moderate  fluence  (~17J/cm2)  and  intensity  (~60MW/cm2) regime.The energy absorbed from the laser beam was partially convertedto thermal  energy,  which  generated  a  series  of  effects,  such  as  melting, vaporization  of  the  molten  material,  shock  waves,  etc.  The  following  Ti-surface  changes  and  phenomena  were  observed:  (i)  superficial  damages  in both   atmospheres;   (ii)   creation   of   cone-and   hill-like   structures   in atmosphere of N2and CO2, respectively; (iii) possible formation of TiN, Ti-oxide(s)  and,  Ti-carbide  layers,  in  N2and  CO2gas,  respectively  and,  (iv) occurrence  of plasma  inboth  gas  ambiences.  It  can  be  concluded  that  the applied laser fluence was high  enough to produce effective modification  of the Ti-implant target in nitrogen as well as in carbon-dioxide gas.

AB  - Pollution control and water purification are the main concerns associated with hazardous component eliminations from wastewaters which have inspired the research, among the others, on various clay minerals as useful adsorbents. The aim of this study was to examine morphological, structural, adsorption, and electrochemical characteristics of serpentinite in order to check its potential for removal of cadmium and textile dyes from synthetic waters. SEM technique has provided a detailed insight into the surface morphology of serpentinite indicating irregularly shaped particles and lamellar aggregates which are characteristic of lizardite mineral. Crystal phases detected in composition of serpentinite by using XRD technique are lizardite and tiny amount of periclase. Serpentinite adsorption characteristics were investigated towards Cd2+ and anionic textile dyes (Procion red MX-5B, Procion orange and Ramazol black) in aqueous solutions. The main goal of the study was the reliable removal of hazardous Cd2+ at low initial concentrations (up to 200 mu g/dm(3)). Textile dyes were taken as the models of anionic organic pollutants in water. All the adsorption experiments were carried out in batch conditions by varying initial parameters such as concentration of pollutant, contact time, mass of adsorbent and pH. Based on the obtained results, serpentinite has proven to be efficient adsorbent with removal efficiency over 98% for the selected pollutants. Native serpentinite was further modified in order to obtain forsterite. Electrochemical characteristics of serpentinite and forsterite were examined by using cyclic voltammetry of solution of 0.1 M H2SO4 as acidic supporting electrolyte and K-4[Fe(CN)(6)] which was chosen as a redox model compound. Due to its specific structure, surface groups, morphology, and non-stoichiometric composition, serpentinite and forsterite exhibited prominent electrocatalytic activity. (C) 2016 Elsevier B.V.

AB  - Samples of natural peat (NP) were hydrothermally treated at different temperatures in oxidative and acidic aqueous medium to tailor their acid-base, adsorption, morphological and other properties. The obtained materials were thoroughly characterized by SEM, XRD and FTIR techniques, followed by determination of pH(pzc), examination of adsorption characteristics and the extent of organic matter leaching in water. Acid-base characteristics of these materials were examined by potentiometric and conductometric titration of corresponding aqueous suspensions. Experimental potentiometric data were interpreted using ProtoFit software (NEM, non-electrostatic model) which provided pKa values and concentrations of surface sites which are compared with corresponding values obtained by conductometric titration method. There are two main types of surface groups (carboxylic and phenolic) that are dominant in the materials and determine their acid-base behavior in the aqueous medium. Temperature during oxidative hydrothermal treatment has no significant effect on the total number of surface groups, but influences the ratio of carboxylic and phenol-type groups. Hence, acid-base properties of peat can be tailored, which is useful in designing and improving adsorptive characteristics of peat for the preferential removal of certain pollutants from water.

Acid-base characteristics of these materials were examined by potentiometric and conductometric titration of corresponding aqueous suspensions. Experimental potentiometric data were interpreted using ProtoFit software (NEM, non-electrostatic model) which provided pKa values and concentrations of surface sites which are compared with corresponding values obtained by conductometric titration method. There are two main types of surface groups (carboxylic and phenolic) that are dominant in the materials and determine their acid-base behavior in the aqueous medium. Temperature during oxidative hydrothermal treatment has no significant effect on the total number of surface groups, but influences the ratio of carboxylic and phenol-type groups. Hence, acid-base properties of peat can be tailored, which is useful in designing and improving adsorptive characteristics of peat for the preferential removal of certain pollutants from water.",

AB  - In this study, modified sol-gel method was employed to synthesize the pure and Zr-doped titania catalysts. Brunauer-Emmett-Teller (BET) method was applied to determine porosity, X-ray diffraction (XRD) analysis was used to study crystal structure, scanning electron microscopy (SEM) was used to investigate morphology and Fourier transform infrared spectroscopy (FTIR) was used to examine surface properties/total acidity of the obtained catalysts samples. Photocatalytic activity was tested in the reaction of crystal violet (CV) dye decolourization/degradation under UV light irradiation. The effects of several photocatalysis operational parameters were considered, such as catalyst dosage, initial dye concentrations, duration of UV irradiation treatment, as well as catalysts calcination temperatures and dopant amounts. The obtained results indicated faster dye decolourization/degradation with the increase of the catalyst dosage and the decrease of initial CV concentrations. The Zr-doping affects photocatalytic properties, i.e. CV decolourization/degradation of the prepared catalytic materials. Thus, addition of 5 wt.% of ZrO2 to titania increases photocatalytic effect for similar to 15% and addition of 10 wt.% of ZrO2 improves the photocatalytic efficiency of titania for nearly 30%.

AB  - Ordered mesoporous carbon, volume-doped up to 3w.% with Pt, Ru and Pt-Ru nanoparticles was synthesized by evaporation-induced self-assembly method, under acidic conditions. The content of incorporated metal was determined by EDX analysis. The X-ray diffractometry confirmed the existence of highly dispersed metallic phases in doped samples. Specific surface area was determined by N-2-physisorption measurements to range between 452 and 545m(2) g(-1). Raman spectroscopy of investigated materials indicated highly disordered carbon structure with crystallite sizes around 1.4 nm. In a form of thin-layer electrode on glassy carbon support, in 0.1M KOH solution, the prepared materials displayed high activity toward oxygen reduction reaction (ORR) in alkaline media, with onset potentials more positive than -0.10 V vs. SCE. The kinetics of O-2 reduction was found to be affected by both the specific surface area and the concentration of metal dopants. The ethanol tolerance of (Pt, Ru)-doped OMCs was found to be higher than that of common Pt/C ORR catalysts. Presented study provides a new route for the synthesis of active and selective ORR catalysts in alkaline media, being competitive with, or superior to, the existing ones in terms of performance and price.

AB  - In order to elucidate the role of B, N, and P dopants in carbon materials on the kinetics of oxygen reduction reaction (ORR) and to provide a fair comparison of the effects of each dopant, a series of ordered mesoporous carbons (OMCs) with low concentration of heteroatoms ( LT 1 at%) has been prepared. Doped OMCs were characterized using X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectroscopy (ICP-OES), Raman spectroscopy, X-ray powder diffraction (XRD), and N-2 physisorption measurements. Comparative study of the ORR activity of these materials in alkaline solution was performed using rotating disk electrode voltammetry. The experiments evidenced that, compared to non-doped OMC, charge transfer kinetics was improved independently on the nature of the heteroatom. The decrease of the ORR overvoltage and the increase of the mass activity upon doping are similar for B and P and less prominent for N. On the other hand, OMCs doped with low levels of B and N were found to be selective for O-2 reduction to peroxide, while for P-doped OMCs, the apparent number of electrons consumed per O-2 molecule was up to 3.1. Experimental measurements were complemented by density functional theory (DFT) calculations.

AB  - This paper deals with comparison of modified carbon electrodes prepared from Pt- and Ag-doped carbon microspheres using cyclic voltammetry of [Fe(CN)(6)](3-)/[Fe(CN)(6)](4-) redox pair as a probe under various experimental conditions. Spherical particles ranging from 0.5 to 8 mu m in average as evidenced by SEM showed slight influence of dopant nature onto their microstructure. FTIR analysis revealed that the involvement of metal species in the carbon structure was followed by their subsequent reduction and rising of oxidized carbon functionalities in the spectra. Electrochemical study showed that all the examined electrodes performed reversible processes with chemically stable generated products and no side chemical reactions. Among them, Pt-doped electrode showed superior electrocatalytic behavior in terms of heterogeneous transfer rate constant and other kinetic parameters. Since minimal addition of Pt in the hydrothermal synthesis resulted in powerful electrocatalytic effect as precious advantage, benevolent impact of carbon microspheres as catalyst support was put into focus of this research.

from pinecones was investigated. The parameters of contact time and Tc-99
concentration were varied. It was established that the sorption half-life, t1/2,
was very short ~ 2.2 min, thus making this sorbent an excellent candidate
for immediate pollution remediation, which is very important in the case of
nuclear accidents. The kinetic data were found to follow closely the pseudosecond-
order (PSO) kinetic model. Boyd model established the sorption
dependence only on film diffusion. The partitioning/distribution coefficient,
Kd, attained was 2729 cm3 g-1. The equilibration time was 3 h at room

AB  - Ordered mesoporous carbon (OMC) was used as an adsorbent for the removal of pertechnetate (TcO4 (-)) anion. The maximum uptake (93 %) of TcO4 (-) was obtained after 60 min of contact. The adsorption of TcO4 (-) is almost pH-independent in very wide pH region (from 4.0 to 10.0). Maximum K (d) of 6.6 x 10(3) cm(3) g(-1) was found at pH 2.0. TcO4 (-) interacts with carboxylic functional groups present at the surface of the OMC by displacing the OH- ions with TcO4 (-) via ion exchange mechanism.
