AB  - In order to achieve widespread application of fuel cell technology, the development of an efficient and economical catalyst is a crucial step. Reducing the diameter of catalyst particles, producing particles with a specific orientation surface, and alloying noble metals with less expensive metals are possible approaches to improve catalyst performance. This study will be focused on novel ways for creating PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn nanoparticles were produced using the microwave assisted polyol method and were supported on high surface area carbon Vulcan XC-72R material. The electrochemical behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry, chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the benefits of microwave synthesis and carefully adjusted metal alloying.

AB  - U radu je prikazano poređenje apsorbovanih doza u brahiterapijskim planovima i Monte Karlo simulacijama u brahiterapiji pacijentkinja sa karcinomom grlića materice. U Odeljenju za brahiterapiju u Kliničkom centru Kragujevac primenjuje se mikroSelektron za intrakavitarnu brahiterapiju u HDR režimu. Ovaj uređaj koristi minijaturni radioaktivni izvor 192Ir u obliku cilindra, aktivnih dimenzija 0,6 mm × 3,5 mm, i visoke početne aktivnosti od 370 GBq.Pre terapije, vrši se kompjutersko planiranje, koje predstavlja kompjutersku rekonstruk-ciju položaja vodiča izvora u pacijentu na osnovu dva radiografska snimka, i izodozno planiranje u odnosu na željene dozimetrijske tačke. Osnovni podaci planiranja su dnevna doza, koja iznosi 700 cGy i broj frakcija; dnevna doza se isporučuje se u tri frakcije jednom nedeljno. Monte Karlo simulacije su obavljene korišćenjem MCNP6 softvera verzije 2.0 kako bi se procenila raspodela doze u materici i kritičnim organima od rizika (bešika i debelo crevo). MCNP F6 tally (MeV/g) je izabran zbog lakog konvertovanja deponovane energije u apsorbovanu dozu. Za pripremu ulaznih datoteka koje simuliraju brahi-terapiju korišćeni su matematički ORNL i voksel fantomi.

AB  - This paper presents the comparison of absorbed doses in brachytherapy plans and Monte Carlo simulation for brachytherapy treatment of a female patient with cervix carcinoma. At the Department of Brachytherapy at the Clinical Center Kragujevac, the microSelectron after loading deviceis used for intracavitary brachytherapy in the HDR regime. This device uses a miniature radioactive source 192Ir in the form of a cylinder, active dimensions of 0.6 mm × 3.5 mm, and a high initial activity of about 370 GBq. Before therapy, computer planning is performed, which represents a computer reconstruction of the position of the source guide in the patient based on two radiographic images, and isodose planning in relation to the desired dosimetry points. Essential planning data are the daily dose and number of fractions. In this case, the daily dose is 700 cGy and is delivered in three fractions once a week. This means that the duration of this brachytherapy treatment will be a total of three weeks. Monte Carlo simulations by using MCNP6 code version 2.0 were applied for brachytherapy treatment to estimate the dose distribution in uterus and several critical organs at risk (bladder and colon). The MCNP tally f6 (MeV/g) was chosen due to easy convert energy deposition toabsorbed dose. The computational ORNL and voxel phantoms were used to prepare input files which simulate brachytherapy.By comparing measured and calculated values, it can be seen that Monte Carlo techniques are a powerful tool for application in brachytherapy planning.

AB  - Silver powders chemically synthesized by reduction with hydrazine and those produced by electrolysis from the basic ( nitrate) and complex ( ammonium) electrolytes were examined by X-ray diffraction (XRD) and scanning electron microscopic (SEM) analysis of the produced particles. Morphologies of the obtained particles were very different at the macro level. The needle-like dendrites, as well as the mixture of irregular and regular crystals, were formed from the nitrate electrolyte, while the highly-branched pine-like dendrites with clearly noticeable spherical grains were formed from the ammonium electrolyte. The agglomerates of spherical grains were formed by reduction with hydrazine. In the particles obtained from the nitrate electrolyte, Ag crystallites were strongly oriented in the (111) plane. Although morphologies of Ag particles were very different at the macro level, the similarity at the micro level was observed between chemically-synthesized particles and those obtained by electrolysis from the ammonium electrolyte. Both types of particles were constructed from the spherical grains. This similarity at the micro level was accompanied by the similar XRD patterns, which were very close to the Ag standard with a random orientation of Ag crystallites. For the first time, morphologies of powder particles were correlated with their crystal structure.

AB  - Cobalt 3D powder particles were successfully prepared by galvanostatic electrodeposition. The electrodeposited cobalt powders were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and SQUID magnetometry. It was shown that the morphology, structure and magnetic properties of cobalt particles were closely associated and could be easily controlled by adjusting the electrodeposition process parameters. The morphology of cobalt powder particles was strongly affected by the hydrogen evolution reaction as a parallel reaction to cobalt electrodeposition. Depending on the applied current density, two types of powder particles were formed: dendrites at lower and spongy-like particles at higher current densities. Morphologies and structures of powder particles were correlated with their magnetic properties, and compared with those of the bulk cobalt. In comparison with the properties of bulk cobalt, the obtained 3D structutes exhibited a decreased saturation magnetization (M-S), but an enhanced coercivity (H-C), which was explained by their peculiar morphology.

AB  - Lead electrodeposition processes from basic (nitrate) and complex (acetate) electrolytes were mutually compared by scanning electron microscopy and X-ray diffraction investigation of the produced powder particles. The shape of dendritic particles strongly depended on the type of electrolyte. Dendrites composed of a stalk and weakly developed primary branches (the primary type) were predominantly formed from the basic electrolyte. Ramified dendrites composed of a stalk and of both primary and secondary branches (the secondary type) were mainly formed from the complex electrolyte. In both types of powder particles, Pb crystallites were predominantly oriented in the (111) plane. The formation of powder particles of different shapes with strong (111) preferred orientation is discussed and explained by consideration of the general characteristics of the growth of crystals in electrocrystallization processes.

AB  - The effect of the regime of pulsating current (PC) on copper electrodeposition in the hydrogen co-deposition range was examined by the techniques of scanning electron and optical microscopes. The quantities of evolved hydrogen and morphologies of electrodeposited copper strongly depended on the applied parameters of square waves PC, such as the current density amplitude (or the amplitude of the cathodic current density), deposition pulse, and pause duration. The increase of the current density amplitude led to intensification of hydrogen evolution reaction, and the change of morphology of electrodeposited copper from dendrites and shallow holes to dish-like holes was observed. For the constant pause duration, the prolonging deposition pulses intensify hydrogen evolution reaction leading to the formation of the honeycomb-like structures. The set of modified equations considering the effect of hydrogen generated during metal electrodeposition processes by the pulsating current regime is also presented. The concept of effective overpotential amplitude was proposed to explain the change of copper surface morphology with the intensification of hydrogen evolution reaction.

AB  - In this study, the effect of the anodic current density in the regime of reversing current (RC) on the quantity of evolved hydrogen and morphology of copper deposits was considered. The quantity of evolved hydrogen was quantified by the determination of the average current efficiency for hydrogen evolution reaction, while morphology and internal structures of electrodeposited copper were analyzed using scanning electron (SEM) and optical microscopy techniques, respectively. In all RC experiments, the cathodic current density of 440 mA/cm(2), cathodic pulse of 10 ms and anodic pulse of 5 ms were applied, while the analyzed anodic current densities were: 40, 240, 440 and 640 mA/cm(2). The number, size and shape of holes formed of detached hydrogen bubbles strongly depended on the selected parameters of square waves RC. Due to the decrease of the quantity of evolved hydrogen with the increasing anodic current density, the change of morphology of copper deposits formed around holes from cauliflower-like agglomerates of copper grains to dendrites was observed. Honeycomb-like structures were formed with the anodic current density values up to 440 mA/cm(2). The compactness of the honeycomb-like structures increased with the increase of the anodic current density. The improvement of structural characteristics of the honeycomb-like electrodes was achieved by the application of the RC regime in comparison with both the pulsating current (PC) and constant galvanostatic regimes. It was found that the regime of reversing current is superior in the production of the honeycomb-like electrodes in relation to other current regimes of electrolysis. (C) 2011 Elsevier B.V.

AB  - Cross-section analysis of copper deposits electrodeposited in the hydrogen co-deposition range at a constant overpotential and in a pulsating overpotential (PO) regime was performed. It was shown that a complete structural analysis of these technologically very important electrodes is impossible without an analysis of their internal structure. An insight into the compactness (or porosity) of the deposits, as well as into the depth of the holes, can only be obtained by this type of analysis.

AB  - Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis of the morphology of the formed deposits. The techniques of scanning electron microscopy (SEM) and optical microscopy were used for the structural analysis of the copper deposits. Honeycomb-like electrodes were formed with an amplitude overpotential of 1000 mV, a pause of 10 ms, and deposition pulses of 3, 5, 10 and 20 ms. Holes formed by attached hydrogen bubbles were surrounded by dendrites (for deposition pulses of 3 and 5 ms) or agglomerates of copper grains (for 10 and 20 ms). In an interval of deposition pulses between 3 and 10 ms, the length of deposition pulse did not affect the size, number and depth of holes. The change of morphology of copper formed around holes was discussed by the effect of quantity of evolved hydrogen on effectiveness of stirring of solution in the near-electrode layer. The application of square-wave PO with the shorter deposition pulses enabled energy savings in the production of such copper electrodes. For example, the applied deposition pulse of 3 ms enabled energy saving of about 15% in relation to the copper electrode obtained with a deposition pulse of 10 ms (for the unchanged number, size and depth of holes).
