Organic synthesis of ampholitic compounds with fluoresceine skeleton. Analytical evaluation of their pKa values, determination of the isoelectric point. Application of LIF pI standards in methods of capillary (CIEF) and gel (GIEF) isoelectric focusation.

The properties of contemporarily used non-freezing mixture based on glycol and corrosion inhibitors will be evaluated with respect to materials used for solar systems construction. The possibility of 1,3-propandiole and glycerine usage for modification of current heat- transfer liquids will be verified. The ratio of polymerization/cleavage and microgel occurrence in basic organic matrix will be tested. On the base of obtained results an innovated inhibition system will be proposed, in which less toxic and environmentally friendly components will be used.

Mycotoxins are secondary metabolites roduced by an organism of the fungus kingdom, including mushrooms, molds, and yeasts. They are toxic for plants as well as for warm-blooded animals including human. They represent very wide group of compounds with relative molecular weight usually below 500 Da. More than 300 of mycotoxins have been described till now, but only some of them occur naturally and more frequently in higher concentration levels in foodstuff. Five compounds from this group are important from the point of view of the human health in a worldwide scale: aflatoxins, ochratoxine A, fumonisines, trichothecenes and zearalenone. The most important mycotoxins are produced by fibrillar fungi of Aspergillus, Penicilunum and Fusarium species. Within the range of this work the occurrence of above mentioned mycotoxins together with fusarium ones in brewing raw materials, especially in malting barley. The possibility of the transfer of mycotoxins to individual intermediates during brewing and to finished beer will be also evaluated.
Theoretical quantum chemical study of thermochemical properties of high-nitrogen energetic materials. The goal of this work is a set up of procedure for calaculation of heats of formation by means of an isodesmic approach.
Theoretical DFT quantum chemical study of primarily reaction steps in thermal decomposition of energetic materials. The emphasis is oriented to the "first step" dissociation of C-NO2 and N-NO2 bonds considering the homolytic dissociation energies and related electron densities.
