Application of Raman spectroscopy for detection of sulfates of self-ignited coal heaps
Košek, Filip ; Jehlička, Jan (advisor) ; Němec, Ivan (referee) ; Vandenabeele, Peter (referee)
This Ph.D. thesis was focused on the application of Raman spectroscopy as the main analytical method for the characterization of neo-formed minerals, notably sulfates, from burning coal waste dumps. This environment associated with subsurface fires gives rise to a variety of uncommon and rare minerals. The specific features of these minerals (metastability, hygroscopy, mixed aggregates) causes that the mineralogical investigation is a challenging task using traditional laboratory-based techniques. Advantages such as the non-destructive nature, the sensitivity to the changes in the hydration degree of sulfates, little or none pretreatment, and the option of measurements directly in the field were the main reasons for applying this spectroscopy method. The scarce availability of spectroscopic data of most gas-vent minerals can be considered as the disadvantage. Therefore, artificial prepared samples of six anhydrous sulfates, which are rarely found in nature, were analyzed by Raman laboratory spectroscopy and a miniature a Raman spectrometer, and specific Raman features as well the differences with hydrated counterparts are shown. Laboratory investigation of two natural hydrated aluminum sulfates, alunogen and khademite, were carried out using Raman spectroscopy and other methods in order to obtain...

Nomenclature of organic compounds
Sezemská, Karolína ; Hybelbauerová, Simona (advisor) ; Veselý, Jan (referee)
One of the expected outputs of organic chemistry in "RVP G" is the application of rules of organic systematic terminology for the description of compounds, with the posibility of sing trivial names. There are several handbooks oriented on nomenclature of organic compounds that are available on Czech market. However, repeated imperfections appear in them permanently: the textbooks do not comply with the hybridisation of carbon atoms, the same simple examples are repeated, the rules are so simplified that they lead to the application of incorrect terminology principles etc. The submitted thesis is dealing with the matters of the terminology of organic compounds - with created tutorial material as its outcome. It is in the form of compendium of organic terminology accompanied by the exercises. The contribution of submitted thesis is complex insight into the theme and collection of tutorial materials intended mainly for the high school teachers first of all. Nevertheless it can be used by the students of high schools or basic courses of colleges as well.
