Study of elektrode materials based on manganese dioxide
 Kos, Lukáš ; Dvořák, Petr (referee) ; Novák, Vítězslav (advisor)
This work deals with the production and use of catalytic materials in fuel cells. The basic focus of work is the production of samples of catalytic materials based on manganese dioxide-enriched mixtures of different dopants. Samples subsequently made to measure, compare with other samples and determine whether the samples are enriched with dopants better than samples without dopant. According to information received, then determine whether they are suitable for use in fuel cells.

Deposition of the thin films for applications of advanced oxidation processes using metal dopants
 KRAJČOVIČ, Jan
The aim of this diploma thesis is deposition of TiO2 thin films onto different types and sizes of substrates, and some of these layers dope by iron or silver. During the work was range of TiO2 layers created using a method of physical vapor deposition namely magnetron sputtering. For these processes was chosen the Dreva ARC 400 Hard Material Coating Plant device. The main aim of these depositions was to attempt to create TiO2 thin films on a substrates of larger surface than its in average laboratory processes usual. For this purpose were TiO2 layers deposited onto square glass plates of side length 10 cm. For comparsion and analysis were also as a substrates used microscope slides and fragments of silicon wafers. These substrates were used for testing of photocatalytic activity and on surface morphology (SEM). The theoretical part of this thesis aims to a methods of deposition TiO2 layers and their characteristics. In the experimental part is the used coating equipment and parameters of each deposition process described. Further the characteristics and results of individual experiments are described.
