Development of Czech Christian Music after the Second Vatican Council
Viktorinová, Barbora ; Saláková, Magdalena (advisor) ; Valášek, Marek (referee)
This Bachelor thesis aims to describe the development of Czech Christian music after the Second Vatican Council. Firstly, it describes the terms spiritual and liturgical music. The thesis then compares the music from the Jewish religion and through the times of Christianity until the Second Vatican Council. Also, there is described the Second Vatican Council, its contribution and the changes in terms of liturgical music. Furthermore, the thesis is focused on the use of liturgical music in the Czech Republic, and it describes the rules for using liturgical music in liturgy with the use of rhythmical instruments; it also explains the liturgy with children and music used for this purpose. The thesis describes the reaction on the Second Vatican Council by the composer Petr Eben and his Trouvere mass; and the Christian bands early after the Council - Ztracená kapela and Učedníci. Also, there is described the current Czech Christian music and the scholas as KaPři, SBM and Adorare. Furthermore, the thesis describes the materials of the music for liturgy and other Christian fellowship occasions. It contains the list of available songbooks, examples of choosing the music for liturgy, and a database of Czech Christian music with an electronic key, which helps to search liturgical music.

Charge Transport through Molecular Towers Based on Tetraphenyhmethane Tripods
Kolivoška, Viliam ; Šebera, Jakub ; Lindner, M. ; Valášek, M. ; Mayor, M. ; Mészáros, G. ; Gasior, Jindřich ; Hromadová, Magdaléna
Molecular platforms with multiple anchors were introduced recently to provide robusi coupling between molecular electronic components and metallic electrodes. In this work, charge transport in tower-shaped single molecule conductors based on tetraphenylmethane tripod possessing three thiol anchors is investigated by scanning tunneling microscopy break junction technique. The effect of tripod substitution pattern and number of repeating units in molecule is addressed. The substitution was found to influence conductance value in early stages of molecular junction evolution, where tower lays parallel to surface. In late stages, the charge is transported through principal molecular axis and junction breaks thermally in tilted configuration.

Charge Transport in Single Oligophenylene Molecular Wires with Different Anchoring Groups
Hromadová, Magdaléna ; Kolivoška, Viliam ; Šebera, Jakub ; Sebechlebská, Táňa ; Gasior, Jindřich ; Nováková Lachmanová, Štěpánka ; Mészáros, G. ; Lindner, M. ; Mayor, M. ; Valášek, M.
This work compares single molecule conductance measurements of selected organic systems containing identical oligophenylene molecular wires and different tripodal anchoring groups. Single molecule conductance G was obtained by a scanning tunneling microscopy break junction technique complemented by theoretical calculations based on the density functional theory and non-equilibrium Green’s function formalism. Two molecules were compared where the same oligophenylene wire is connected to one of the electrodes via a tripod substituted on each leg by a thiol group either in the meta or para position. By combined experimental and theoretical analysis it was possible to confirm that single molecule conductance in the metal-molecule-metal junction of both molecules corresponds to a fully extended molecular wire, which is attached to one of the electrodes by all three thiolate bonds of the tripod. Experimental results confirmed that G value of meta-connected molecules is lower than that of para, whereas junction formation probability was higher for meta functionalization.

Synthesis of modular components for molecular electronics
Valášek, Michal
This work is focused on synthesis of new modular components (molecular wires, insulators, diodes, sensors and self-assembled compounds), which may find application in molecular electronics. In the first part of this work, procedure for the preparation of "molecular wires", based on the oligomers of pyridinium salts, is described. The synthetic strategy is based on a stepwise prolongation of these rodlike molecules by reaction of terminal amino group with the monofunctional units. The series of pyridinim oligomers of well-defined length have been prepared without complicated separation of complex mixtures of oligomers. The following part of work describes synthetic approach for the preparation of pyridinium oligomers ending with alkylsulfanyl or acetylsulfanyl groups. These compounds are further used to study the conductivity of conjugated oligomers, after anchoring between the gold electrodes. The following section deals with the preparation of "molecular insulators" based on a rigid bicyclo[2.2.2]octane, 1,12-dicarba-closo-dodecaborane and 1,10-dicarba-closo- decaborane units. The next part deals with the preparation of a series of five "molecular diodes", where the acceptor part (pyridinium monomer) and donor part [(η4 -tetraarylcyclobutadiene)(η5 - cyclopentadienyl) cobalt complex] are mutually separated...
