Iron and its compounds
Krpoun, Karel ; Kábelová, Božena (referee) ; Pilátová, Ivana (advisor)
The focus of the bachelor’s thesis are possibilities of synthesis of selected compounds of the iron. In theoretic part there are closely described chemical and physical properties of ferric sulfate, ammonium ferric sulfate dodecahydrate, ferric oxide, ferric hydroxide and potassium ferric oxalate. The optimal procedure of preparation of tree follow-up compounds of the iron is devised from the result of experimental section.

Optimization of Material Plastification Process
Šeniglová, Hana ; Krpoun, Karel (referee) ; Pantělejev, Libor (advisor)
This bachelor´s thesis deal with the optimization of the process of material plastification. The purpose of the thesis is to devise feasible parameters of a injection molding machine. The goal was achieved by the „Design of Experiments“ method. The necessary measurements were taken on the sample, a filter fuel tank, which was provided by the company Robert Bosch České Budějovice. Each measurements are described in the bachelor´s thesis. The results are summarized and evaluated in the Minitab software used for optimal parameters settings of the production process.

Catalytic Systems for Cyclic Ester Polymerization
Krpoun, Karel ; Hermanová, Soňa (referee) ; Richtera, Lukáš (advisor)
Usage of complexes in homogeneous catalysis for synthesis functional materials with defined properties is one of the most significant areas of research organometallic compounds of lanthanides in the last decade. One of the way became polymers with defined properties is for example ring opening polymerization. Aliphatic polyesters, which are biodegradable and biocompatible (useful for biomedicine), can be prepared by this method. Theoretical part of this work includes preparation of lanthanidocenes, their characterization and possibilities of their use for polymer synthesis. The aim of experimental part was performance and optimizing synthesis of series lanthanocen chlorides complex (Sm, Nd a Pr) and new monopentamethylcyklopentadienyl complexes. Introduced structural types were chosen for their possibility of polymerization activity or their activation by adding alkyl reagents. The complexes were spectral characterized by 1H NMR, and IR spectroscopy. Structure was defined by roentgen structural analysis. Catalytic activities for polymerization of ?-caprolacton in toluen (laboratory temperature) were performed for selected complexes. Polycaprolactone was characterized by gel permeation chromatography and NMR.
