The copper ore bed at Mutěnín in Western Bohemia and the question of its exploitation in the prehistory
Chmelíková, Dana ; Bláhová, Zuzana (advisor) ; Metlička, Milan (referee)
The present bachelor thesis aims to clarify the question of possible use of copper mines in Mutěnín in Western Bohemia in prehistoric times, especially since the Bronze Age settlement in the region. Authors engaged in the prehistoric settleents in the West Bohemia, refer to the isme from 60 years of the 20th century. The identification of prehistoric relicts mines activites in the Czech Republic is very difficult, because most were destroyed in the extraction of modern times. For research purposes, there are only very limited ways. One of them is the study of archival materials on historical production, which, although to look far into the Middle Ages - in our case, only the 16th century. However, thanks to them we get information on the shape mines in the past. The only relatively effective form of archeological research in the surveyed area is the surface collection, which was carried out this work. For knowledge of prehistoric settlement in the vicinity of copper mines, we needto focus on the wider area. For purposes of this work was created an area of 15 km around the site. The task of this study was to explore the posibility of the identification of copper ore in bronze artifacts. The first step was the analysis of elemental composition raw material from Mutěnín. The purpose of the work should...

Li+ a H+ vodivé polymerní elektrolyty s kovalentně vázanými anionty
Reiter, Jakub ; Michálek, Jiří ; Přádný, Martin ; Chmelíková, Dana ; Širc, Jakub
New single-ion conducting electrolytes based on methacrylates were prepared using direct, radically initiated polymerisation: copolymers of methacrylic acid (MA) or lithium methacrylate (LiMA) with 2-ethoxyethyl methacrylate (EOEMA) and poly(ethylene glycol) methyl ether methacrylate (EGMEMA) as pure cationically conducting Li+ or H+ electrolytes and covalently bonded carboxylic group. For the conductivity improvement, a set of electrolytes with embedded aprotic solvent (propylene carbonate PC or N,N-dimethylformamide DMF) was prepared.
Polymerní gelové elektrolyty na bázi poly(ethylmethakrylátu) and poly(2-ethoxymethyl methakrylátu)
Reiter, Jakub ; Michálek, Jiří ; Vondrák, Jiří ; Chmelíková, Dana ; Přádný, Martin
New methacrylate-based polymer electrolytes were prepared using UV initiated radical polymerization. Prepared composites were characterized using voltammetrical and impedance methods and their composition was optimized.
