The Effect of Quartz Sand and Feldspar Granulometry on the Sintering of Porcelain Body
Bajer, Tomáš ; Nevřivová, Lenka (referee) ; Sokolář, Radomír (advisor)
Properties of quartz and feldspar as two most used fundamental materials for porcelain production have significant effect on final technical properties of the product. Generally, it is considered the finer the materials the better the end product’s properties. The degree, to which particle size distribution influences these properties and the reason why, is summarized in this paper. At the end, practical tests were performed to confirm the gathered information.
The study of utilization of raw materials based on glass recyclate
Bajer, Tomáš ; Čermák, Jan (referee) ; Šťastník, Stanislav (advisor)
Presented work deals with the problem of solar glass waste recycling. In theoretical part recent EU regulation regarding waste management is presented. Different ways of PV panels recycling are explained as well as raw materials for glass production are listed. Differences between regular and solar glass is explained. In experimental part different recipes using solar glass waste and polymer binders are presented. Grindability was tested on specimen tiles. Potential of solar glass waste for manufacturing products with acoustic properties was examined.
Quantification of main solution components by using fragments containing heavy nuclides of common elements
Horká, Blanka ; Čabala, Radomír (advisor) ; Bajer, Tomáš (referee)
Quantification of major components by gas chromatography with flame-ionization detector (GC-FID) is established in routine laboratory practice. The FID detector is considered as universal detector for gas chromatography (GC), but it does not provide a response for a wide range of compounds and GC-FID analysis provides only quantitative data. The coupling of gas chromatography with mass spectrometry is a powerful analytical tool that provides not only quantitative data but also qualitative data on the structure of substances. When quantified by GC-MS, the detector oversaturation is a problem as it is a highly sensitive detector (at ppb level). One way to avoid oversaturation of the detector is to significantly dilute the solutions, which causes a decrease in the sensitivity of the method. Another approach to bypass detector saturation is to interrupt detection during solvent elution. For quantification of the major components of solutions, only the first method of bypassing detector saturation can be applied, but it is a labor-intensive process that increases the measurement uncertainty. The interruption of detection during solvent elution is not applicable for the purpose of quantifying major components, so a new approach of quantifying major components of solutions using M+1 ions was proposed and...

Sustainability as an international business strategy
Hon, Kryštof ; Taušer, Josef (advisor) ; Bajer, Tomáš (referee)
This thesis defends a hypothesis of transition towards sustainable development through the use of management and marketing tools within free market conditions. The main idea is the use of changing consumer preferences in favour of nature friendly products as a business opportunity.
