Measurent and analysis of genomic signal Solanum tuberosum.
Štekovič, Michal ; Hubálek, Jaromír (referee) ; Valla, Martin (advisor)
This thesis describes the basic methods for measuring and analyzing DNA. The first part covers the description of the DNA. The next section is devoted to the principle of obtaining DNA from the sample, its isolation and purification. Describes the apparatus which is necessary to measure and analyze. In the final section is devoted adsorptive voltammetry method, evaluation of measured results and data processing assistance program MATLAB.
Optimization of Cavity Fabrication in Low Temperature Co-fired Ceramics
Dóczy, Robert ; Somer, Jakub (referee) ; Štekovič, Michal (advisor)
This work deals with the fabrication of closed cavities in Low Temperature Co-Fired Ceramics (LTCC). In recent years, the LTCC ceramics have become widely used in the areas of sensors, MEMS and micro-fluidic applications. When fabricating such devices, it is important that the cavities maintain their compactness and dimensions after the manufacturing process . This is achieved primarily with the right choice of lamination process and its parameters and also by appropriate setting of the firing profile. The theoretical part describes the various steps in the production of LTCC structures and the most common technological processes used for creating structures with cavities and micro - channels . In the practical part are selected laminating procedures performed on the test pattern, which contains cavities of different sizes. Emphasis was placed on the correct execution of each method , while gradually modifying the lamination parameters. The achieved results are further discussed in terms of process parameters and their influence on the dimensions of manufactured cavities.
The electrochemical sensors with 3-D structure of electrodes
Štekovič, Michal ; Hrdý, Radim (referee) ; Adámek, Martin (advisor)
Miniature electrochemical sensors can be produced by thick-film technology. The optimal properties of thick-film electrode system, the production technology optimization of thick-film sensors and the adjustment of optimal technological properties are main problems of sensor design. An area of working electrode and an electrode topology design is the important parts in design of electrode system optimization. The rules for optimization of electrode systems in classical electrochemistry exist. The design of standard thick-film electrode construction is limited (2-D construction, substrate dimensions, resolution, paste parameters …). Therefore rules for classical electrode systems cannot be used fully in this case and larger electrode area can be making by 3D structure only. One of resolutions is unconventional method. The increase of working electrode surface by unconventional method – ball and wire bonding is discussed in this work.
Cold Chemical Lamination of Low Temperatue Co-fired Ceramics
Jurásek, Matěj ; Somer, Jakub (referee) ; Štekovič, Michal (advisor)
This paper deals with production of the structures fabricated using low temperature co-fired ceramics. Focus is on the lamination of raw ceramic tapes. There are presented classical thermo-compressive methods and a new method using chemical solutions for tape bonding. Describes new lamination technology and their advantages are the absence of elevated temperatures and high pressures. This method reduces using of higher temperatures and high pressure during lamination. On the other hand, chemical process of tape bonding is not flawless. There are many problems including solvent deposition, extreme sensitivity to dust and other processing parameters. It also describes the fabrication of structures by chemical way. Specifically, analyzes the method Cold Chemical Lamination and provides examples of possible deposition solvents which are needed for etching the surface of the LTCC tape during the lamination.
