AB  - The consequence of drastic reduction in fossil fuel reserves has forced the
scientific community to find and develop new ways to exploit renewable resources and
optimize the process of polymer materials production. The aim is to obtain applicable
polymer whose complete life cycle is set in ecological framework. Poly(lactide) (PLA)
meets these requirements as biodegradable polyester whose monomer is derived from the
plant feedstock containing carbohydrates. PLA could be prepared using the different
synthesis routes, but from the point of energy saving, as well as environmental protection,
the microwave synthesis of PLA is the best solution. In this work, poly(L-lactide) were
synthesized in microwave reactor. Reaction time was varied, while the other parameters of
the synthesis were constant. The structures of obtained polymers were confirmed by Fourier
– transform infrared spectroscopy (FT-IR). For determination of molar masses of poly(Llactide) samples, the gel permeation chromatography (GPC) was applied. Thermal
properties were investigated by differential scanning calorimetry (DSC).

AB  - This study evaluates the genotoxic potential of two Ru(III) complexes with thiosemicarbazone based ligands. The complexes were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using the cytokinesis block micronucleus (CBMN) assay at concentrations 1.5; 3.7 and 7.4 μg/mL. The cell culture treated with the tested complexes, at 3.7 μg/mL concentration, decreased a frequency of micronucleus for 37% and 32%, when compared with the control cell cultures. At concentration of 7.4 (1.5) μg/mL of this complexes exhibited slightly lower effect of micronucleus for 30% (35%) and 27% (29%), when compared with the control cell cultures.

AB  - In this study, novel hexa coordinated ruthenium(III) complex of the type Na[RuCl2L2)] (where L = monobasic bidentate Schiff base derived from the condensation of 5-nitrosalicyladehyde with aniline) has been synthesized and characterized by electrospray ionization time-of-flight mass spectrometry, infrared spectroscopy and ultraviolet/visible spectrophotometry. Schiff base N-phenyl-5-nitrosalicylideneimine is coordinated to the ruthenium via imine nitrogen and phenolic oxygen. Mass spectra showed molecular ion (M-) at m/z 653.9641 which corresponds to [C26H18Cl2N4O6Ru]-. The in vitro antimicrobial properties of the Schiff base and the complex were tested by micro-dilution technique and agar plate assay for determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The compounds showed a higher antibacterial activity against tested Gram-positive bacteria (Staphylococcus aureus ATCC 33591 and ATCC 29213), whereas against the Gram-negative bacteria (Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 700603) were ineffective. The genotoxic effects of Ru(III) complex were investigated using the Cytokinesis Block Micronucleus (CBMN) assay in human lymphocytes cultures. The cell culture treated with the complex at a concentration of 3.7 µg/mL exhibit the most prominent effect of decreasing the frequency of micronucleus for 44%, while at the concentrations of 1.5 and 7.4 µg/mL effect is slightly lower (40%), compared to the control cell culture.

AB  - Solvent base oils of group API I contain larger quantities of aromatic compounds and sulfur, as compared to base oils of higher quality groups. Processing of base oils by commercial clays is performed in order to reduce the content of undesirable compounds, improving the color and oxidation stability. Commercial clays are based on aluminosilicates with a large specific surface area and developed porosity. Bentonite has good adsorption characteristics, which can be further improved by various methods of modification. In this paper, adsorption processing of solvent base oils is derived by acid-activated bentonite and commercial clay. The structural composition of starting oil and refined solvent oil (content of aromatics, paraffins, naphtenes and sulfur) is determined by following methods: IEC 590, UV, IP 346 and BAS ISO 20846. The results showed that processing of a solvent oil by activated bentonite leads to change of structural composition, similar to a change achived by processing with commercial clay.
