    Abstract In this study, eighteen new ligands (B1-B18) containing a thiosemicarbazide core were synthesized and characterized in terms of physicochemical properties, molecular docking and in vitro biological activity. The structures of eleven ligands were investigated using X-Ray diffraction and Hirschfeld Surface analysis. To study the structure-activity relationship, the organic ligands contained pyridin-2-ylmethyl, pyridin-3-ylmethyl or pyridin-4-ylmethyl moieties and various substituents. Their pharmakokinetic profiles and molecular docking results suggest high potential as new drug candidates. The complexing ability of the selected organic ligands was also evaluated, yielding five new Cu(II) complexes (Cu(B1)Cl

    Abstract Atmospheric corrosion is a significant problem given destruction of various materials, especially metals. The corrosion investigation in the industrial city environment was carried out during one year exposure. Corrosion potential was determined using the potentiometric method. The highest effect of corrosion processes was observed during the winter season due to increased air pollution. Corrosion of samples pre-treated in tannic acid before the exposure was more difficult compared with the samples without pretreatment. The corrosion products determined with the SEM/EDS method prove that the most corrosive pollutants present in the industrial city air are SO2, CO2, chlorides and dust.

  8. Article: Application of TiO₂–RuO₂/Ti electrodes modified with transition metal oxides in photoelectrochemical degradation of H-acid - synergetic effect

    Abstract Results of investigation of H-acid degradation in photoelectrochemical process with the application of TiO₂–RuO₂/Ti electrodes modified with transition metals oxides like: Nb₂O₅, ZrO₂ and Y₂O₃, are described. Comparison of H-acid conversion calculated as a change in COD and TOC in photocatalytic, electrochemical and photoelectrochemical process shows that the highest conversion was achieved in the photoelectrochemical process due to a significant synergetic effect. The synergetic effect in the photodegradation of H-acid was estimated as a parameter – synergetic factor (SF). It appeared that SF depended on current intensity applied in the photoelectrochemical degradation of H-acid and on modification of titanium electrodes. The highest synergetic effect was obtained in the case of TiO₂–RuO₂/Ti electrodes modified with Nb₂O₅ in the atmosphere of nitrogen and applied in the processes carried out at the current intensity of 0.3A.
