AB  - Being a member of the nanofamily, carbon nanomaterials exhibit specific properties that mostly arise from their small size. They have proved to be very promising for application in the technical and biomedical field. A wide spectrum of use implies the inevitable presence of carbon nanomaterials in the environment, thus potentially endangering their whole nature. Although scientists worldwide have conducted research investigating the impact of these materials, it is evident that there are still significant gaps concerning the knowledge of their mechanisms, as well as the prolonged and chronic exposure and effects. This manuscript summarizes the most prominent representatives of carbon nanomaterial groups, giving a brief review of their general physico-chemical properties, the most common use, and toxicity profiles. Toxicity was presented through genotoxicity and the activation of the cell signaling pathways, both including in vitro and in vivo models, mechanisms, and the consequential outcomes. Moreover, the acute toxicity of fullerenol, as one of the most commonly investigated members, was briefly presented in the final part of this review. Thinking small can greatly help us improve our lives, but also obliges us to deeply and comprehensively investigate all the possible consequences that could arise from our pure-hearted scientific ambitions and work.

AB  - The paper presents results of the influence of mechanical activation of shungite, a carbon-mineral rock material rich in silica and carbon, on its sintering behaviour, and obtaining of pure SiC ceramics. The mechanical activation of the starting powder was performed in a high-energy ball mill in time intervals from 30 to 480 min. The phase composition of the starting powders and sintered samples was analysed by the X-ray diffraction method. The first traces of SiC were detected after sintering at 1350 °C for 2 h in an Ar atmosphere, along with traces of unreacted SiO2. The scanning electron microscopy was performed in order to determine changes in the microstructure. Sintering was performed at various temperatures for 2 h, in an Ar atmosphere and a vacuum. Dielectric properties of the sintered samples were measured in the frequency range from 1 to 500 MHz. The obtained results indicate that the sintered powder is a good candidate for applications as an absorber of electromagnetic waves in microwave engineering. © 2019 University of Novi Sad, Faculty of Technology.

AB  - This study of environmental radioactivity was carried out in the soils of an urban area. Naturally occurring gamma-emitting radionuclides and man-made137Cs were found in the soil profiles collected from four parks in the central Belgrade city area and the soil layer was examined every 10 cm and to a depth of 50 cm. Radioisotope activity concentrations (Bq kg−1) in the samples of urban soil using the gamma-ray spectrometry method were in the range of 14–46 for238U, 33–50 for226Ra, 29–63 for210Pb, 1.2–3.4 for235U, 28–50 for232Th, 424–576 for40K and 0.7–35.8 for137Cs. Some of the basic physicochemical soil properties (pH, organic matter content, calcium-carbonate content, particle size distribution) were determined to investigate the impact on the vertical distribution of radionuclides. The results of this investigation showed that variations of activity concentration ratios of radionuclides that belong to the same (238U/226Ra) or different radioactive series (232Th/226Ra;235U/238U), including210Pb/137Cs ratios could well be explained by the properties of the soil. Alkaline pH reaction, the accumulation of organic matter in the uppermost and of carbonates in the deepest layers of urban soil had an effect on238U/226Ra, and210Pb/137Cs activity concentration ratio values, while232Th/226Ra and partially235U/238U ratios were associated with the particle sizes vertical distribution. A study of radionuclides in the samples of leaves of two deciduous tree species common for these parks was also conducted and210Pb and40K were found concentrated in leaves rather than other investigated radionuclides.

AB  - Electrodes based on composites of zeolites with carbonized polyaniline prepared in the presence of 5-sulfosalicylic acid are evaluated for both qualitative and quantitative determination of phenols in aqueous solutions. Zeolites used included NaX and NaY, as well as their transition metal (Mn and Cu) cation-exchanged forms, and they were all characterized usingXRPD, FTIR and SEM. Cyclic voltammetry was used to study composites electrochemical response in the presence of p-nitrophenol, phenol and 5-aminophenol in acidic, neutral and al- kaline media. Linear dependence of current on p-nitrophenol concentration in acidic media was obtained in 0.11 mM concentration range. The comparative evaluation of the electrochemical response of NaX/carbonized polyaniline composite and its individual components revealed significantly lower limit of detection obtained using composite electrode (1.27 mu M) compared to that obtained using pure zeolite (135 mu M) or pure carbonized polyaniline (94.5 mu M) electrode. Composite electrode gave response to p-nitrophenol presence in neutral media as well, but it quickly disappeared with continuous scanning, while no clear response could be seen in highly alkaline media. Thus, this work demonstrates benefits of using novel composite based on zeolites and carbonized polyaniline for sensing of phenols in acidic aqueous solutions. (C) 2016 Elsevier B.V.

AB  - n The present paper focuses on the determination of radiological characteristics of cultivated chernozem soil and crops from long-term field experiments, taking into account the importance of distribution and transfer of radionuclides in the soil-plant system, especially in agricultural cropland. The investigation was performed on the experimental fields where maize, winter wheat, and rapeseed were cultivated. Analysis of radioactivity included determination of the gross alpha and beta activity as a screening method, as well as the activities of the following radiouclides: natural (Pb-210, U-235, U-238, Ra-226, Th-232, K-40, Be-7) and artificial (Sr-90 and Cs-137). The activities of natural and artificial (Cs-137) radionuclides were determined by gamma spectrometry, while the artificial radionuclide Sr-90 was determined by a radiochemical analytical method. Based on the obtained results for the specific activity of K-40, Cs-137, and Sr-90, accumulation factors for these radionuclides were calculated in order to estimate transfer of radionuclides from soil to crops. The results of performed analyses showed that there is no increase of radioactivity that could endanger the food production through the grown crops.

AB  - This is a preliminary study of the depth distribution of Cs-137 radionuclides in cultivated anthrosol soil of a 15-year old peach tree plantation at the experimental field Radmilovac near Belgrade. Before planting, the soil was ploughed at the depth of 1 m. The soil had not been annually ploughed, irrigated and treated with mineral fertilizers for three years before sampling. Activity concentration for Cs-137 ranged from 1.8 Bq kg(-1) to 35 Bq kg(-1). Along the soil depth it varied highly, reaching as high a total variation coefficient as 83 %. Radiocaesium distribution patterns depended on the extent of soil mixing in the plough layer, as it was mechanically transferred from the surface to the lower soil layers during cultivation. Cs-137 was associated with humus content and fixation to clay fractions in the soil. Our results single out soils hygroscopic water as a valuable parameter for Cs-137 behaviour that could be used commonly if the measurement is standardised.

abstract = "This is a preliminary study of the depth distribution of Cs-137 radionuclides in cultivated anthrosol soil of a 15-year old peach tree plantation at the experimental field Radmilovac near Belgrade. Before planting, the soil was ploughed at the depth of 1 m. The soil had not been annually ploughed, irrigated and treated with mineral fertilizers for three years before sampling. Activity concentration for Cs-137 ranged from 1.8 Bq kg(-1) to 35 Bq kg(-1). Along the soil depth it varied highly, reaching as high a total variation coefficient as 83 %. Radiocaesium distribution patterns depended on the extent of soil mixing in the plough layer, as it was mechanically transferred from the surface to the lower soil layers during cultivation. Cs-137 was associated with humus content and fixation to clay fractions in the soil. Our results single out soils hygroscopic water as a valuable parameter for Cs-137 behaviour that could be used commonly if the measurement is standardised.",

AB  - This paper introduces the distribution background and unique characteristics of Cs-137 in cultivated and undisturbed areas. The samples were taken from three measuring points of the depth of 1 m. We examined all visible horizons and determined their classifications. There were four horizons in one profile. All four horizons had a different zone thickness. Cs-137 is an artificial radionuclide that has been produced primarily as a result of atmospheric thermonuclear weapon tests since the 1950. Also, the great amount of Cs-137 (similar to 85 PBq) was released in the atmosphere during the Chernobyl accident. So, Cs-137 has been globally distributed, with fallout rates generally related to latitude and precipitation depth. The movement of Cs-137 in soil is primarily controlled by soil erosion processes, such as processes caused by water, wind, and tillage. Thus, Cs-137 is a valuable tracer to study soil erosion. The specific activity of Cs-137 in soil and sediment samples was determined by using the gamma-spectrometric method.

AB  - Taking into account the importance of distribution and transfer of radionuclides in the soil-water-plant system, especially in agricultural fields, in this study, natural radionuclide determination in regosol-type soil was performed. The correlations between main soil properties and the contents of natural isotopes (238)U, (226)Ra, (232)Th, and (40)K in agricultural soil and their distribution through the soil depth was studied. For determination of natural radionuclide activity concentration, we used the CANBERRA HPGe detector, applying the gamma spectrometry method. The investigation was performed on an experimental peach tree field characterized by a anthrosol type of soil, derived from the chernozem type of natural soil. The effect of measured soil properties on activity concentration levels was analyzed by simple and multiple linear regression analysis. Considering the linear model, in our soil profiles of 0-80 cm depth, clay content was positively related with (238)U, (226)Ra, and (40)K, and about 30% of the variation of those radionuclides was explained. Sand fraction was negatively related with (238)U, (226)Ra, (232)Th, and (40)K and the correlation was medium, except for (226)Ra (r = -0.68). The joint effect of pH, carbonates, humus, clay, and sand contents on natural radionuclide distribution in the 0-80 cm layer was found by multiple linear regression analysis. Radionuclide behavior was explained by the R-squared statistic. The investigations of uranium distribution showed that when the soil layers of 0-20 cm and 60-80 cm are considered together, uranium behavior is affected by soil pH and the content of humus, carbonates, and clay. Multiple regression analysis of (226)Ra, (232)Th and (40)K activities in soil layers of 0-20 cm and 60-80 cm showed that their lower mobility and uniform depth distribution are associated with small variations of carbonates along soil depth and mineral composition of the parent materials, while the soil pH had no effect on their behavior.
