Capacitive sensor in low temperature co-fired Ceramic
Symerský, Tomáš ; Řezníček, Michal (referee) ; Kosina, Petr (advisor)
This bachelor thesis deals with theoretical knowledge of basic materials especially of a low-temperature ceramics, which enables creating multi-layer structures. Different defects occur by forming these structures, especially in the area of cavernas and micro-tubules. This thesis uses different methods which lead to an elimination of these defects. The thesis also deals with techniques which can be used to a realization of these sensors. Achieved knowledge helped to draft and realize the capacity sensor of flow and pressure in a low-temperature ceramics. The pressure sensor was tested by the load in the frequency spectrum, while the flow sensor was tested for different substances.

Comprehensive chemical analysis of blood coatings
Matěcha, Tadeáš ; Kučková, Štěpánka (advisor) ; Kolář, Karel (referee)
This thesis deals with the comprehensive chemical analysis of blood coatings using mass spectrometry and infrared spectroscopy. The theoretical part focuses first on the history of use, properties, and formulations of blood coatings, then on their composition, which is divided into protein and non-protein components, as well as on selected analytical methods used for their identification. In the experimental part, 41 model samples and 2 real samples are evaluated and discussed. Liquid chromatography with tandem mass spectrometry (nano-LC-ESI-Q-TOF MS) was used to identify the protein component in all samples. Determination of the quantitative abundance of each type of protein additive in the blood coatings was performed based on the number of peptides found originating from proteins typical for specific protein additives. Furthermore, it was possible to identify the amino acid sequences that allow to determine the animal origin of the blood used. The non-protein components of all samples were identified by infrared spectroscopy, specifically by the attenuated total reflection and diffuse reflectance techniques. The quantitative analyses based on the change of the intensities of the measured spectra was also discussed. A special chapter is devoted to the identification of animal glue and to the...
