Raman spectormetry in Art
Minaříková, Laura ; Jehlička, Jan (advisor) ; Osterrothová, Kateřina (referee)
This thesis deals with the use of Raman spectroscopy in the arts, specifically in the identification of precious stones and semi-precious stones in various art works. This work describes the basics of this method, options and practical use based on selected scientific publications. The existing results of research in recent years shows that this spectroscopic analytical method on the rise. It is thanks to the many advantages that this method offers skilled in the art. The main advantages of Raman spectroscopy include speed and affordability analysis, minimal or no sample preparation, and most importantly - non-destructive to sample and explore the possibility of sample on the spot, without having to often very difficult transport to the laboratory. Key words Raman spectrometry, art, characterization of artifacts

Charakterizace mikrostrtuktury kvazikrystalického aproximantu Al77,5Cr16,5Fe6
Svoboda, Milan ; Buršík, Jiří ; Janovec, J. ; Dolinšek, J.
Characterisation of the quasicrystalline approximant in Al77,5Cr16,5Fe6 alloy is the main aim of this work. The characterisation was performed by transmission electron microscopy,electron diffraction,scanning electron microscopy and energy dispersive X-ray spectroscopy. By using those methods we have identified 2 phases differing each other especially by content of iron.
