    Opis:
    The aim of this study was to investigate the new method of polythiophene polymerization. It was made an attempt of the chemical oxidation of thiophene in aqueous medium without the addition of any surfactant. The oxidative compound applied in the synthesis was gaseous ozone. Resulting polymer was obtained in the form of nano-spheres dispersed in water. The method developed in this study allow to obtain the polythiophene nanoparticles. Further study is required to fully identify the resulting product properties in comparison with polymer obtained in other methods.

    Opis:
    The manuscript presents experimental research on a plasma reactor with two mesh electrodes and a micanite dielectric. Three types of electrode geometry were used in experimental research; mesh size 0.1 x 0.1 mm, 0.3 x 0.3 mm and perforated electrodes with Ø1.38 mm holes. The results of experimental research show the influence of electrode geometry on the ozone generation process. The use of electrodes perforated with Ø1.38 mm holes generates 20% lower ozone concentration, compared to the configuration with two mesh electrodes size 0.1 x 0.1 mm at the same power of discharges.

    Opis:
    Many researchers from around the world are looking for better and cheaper means of ozone production. One of the methods of increasing the efficiency of ozone production is the use of a rotating electrode presented in this paper. Experiments were carried out which showed that the most important parameters are the materials used in the electrodes and the condition of their surface. The metallographic investigations of the electrodes after continuous work for a month were made, which show how the raids layers are formed. As a result of working in a highly oxidizing environment, the electrode is oxidized in a process of chemical corrosion. It is obvious that the layer of corrosion products created during the work of the plasma reactor isolates the surface of the electrode, which reduces the intensity of the electric field, causing a decrease in the amount of plasma generated, which reduces the concentration of ozone during this process. The dynamics of the plasma generation process and the type of electrode material working in changing process conditions are the decisive factors influencing the concentration of ozone produced. The influence of the medium, which is the electrode material, depends mainly on its resistance to corrosion in the environment of dynamically changing conditions, e.g. electrode rotation, oxygen flow through the rotating electric field and the month-long working time of the plasma reactor.
