Shale gas extraction
Podhorský, Jakub ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor’s thesis on Shale gas extraction describes extraction and world shale gas resources. At the beginning it provides introduction to the terms of geology and overview of historical evolution of extraction and crucial technologies that are currently used in extraction. Shale gas exploration and extraction development is briefly mentioned. Horizontal drilling and hydraulic fracturing is then further described and also summary of the equipment is provided. Potential environmental risks associated with extraction or hydraulic fracturing itself are described. Subsequently world shale gas resources and potential extraction places are described. World technically recoverable resources are estimated at 7245 Tcf. Shale gas commercial production is currently underway in the United States, Canada and China.

Methods for the fast detection of water and degradation changes in lithium based electrolytes
Šimek, Antonín ; Čech, Ondřej
This paper deals with lithium-ion batteries,specifically the electrolytes used. The degradation mechanisms oflithium-ion batteries are addressed, with a focus on electrolytedegradation. A considerable part is then devoted to thedegradation of lithium hexafluorophosphate, especially afterexposure to water or moisture. The decomposition of the lithiumsalt is linked to the evolution of hydrofluoric acid, whose influenceon the electrolyte parameters and methods of fast detection is thesubject of the experimental section.

Environmental Problems in Europe in Relation to the Environmental Policy of the European Union
Medková, Kateřina ; Jeníček, Vladimír (advisor) ; Abrhám, Josef (referee)
This thesis deals with certain environmental problems in Europe and with attempts to solve these environmental problems within the framework of the European Union. The purpose of this work is to make its readers acquainted with the scope of the EU environmental policy and Community legislation on the protection of the environment. The thesis is focused on four main subject-matters: (i) climate change as a consequence of the global warming process, (ii) air pollution and the ozone layer depletion, (iii) water contamination and (iv) soil degradation. The issue which of the environmental problems require a regional approach and which a global approach is also considered in the thesis.
