Electrolytes based on sulfolan and similar solvents
Máca, Josef ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
Submitted thesis deal with study of aprotic electrolytes in order to increase the safety for use in lithno – ionts accumulators. Increase of safety is specified by measuring the flash point of each electrolytes, at the same time are evaluated also other parameters important for use in accumulators. For determine the window of temperatures where the electrolytes can work is measured by melting point. The melting point is measured by cryoscopy. From electrical properties is measured specific conductivity of the electrolyte.

Optimized manufacturing of aluminium castings by using lost wax technology
Talanda, Ivan ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
Aim of this diploma thesis is to choose new pattern wax for Fimes a.s. foundry. New wax should substitute old not fully satisfactory pattern wax which caused problems in technological process resulting in increased number of rejects. New pattern wax should eliminate current problems and help foundry with producing large, thin-walled, high-quality castings. Numbers of pattern waxes supplied by world’s leading wax manufacturers were subjected to laboratory tests and pilot study. This diploma thesis is part of project Alfa TA01010766: „Research and development of production technology large, thin and high quality castings of aluminium alloys “

Rheological properties analysis of heat transfer fluids
Neradil, Petr ; Hylský, Josef (referee) ; Frk, Martin (advisor)
This master thesis deals with the issue of heat transfer fluids for solar thermal system. It discusses the different types of solar systems and their use. It also describes the different types of heat-transfer fluids for solar thermal systems and analyzes the basic chemical composition of commercially available heat-transfer fluids. There are described the properties of these fluids and methods for measuring certain properties. The practical part deals with measuring the temperature dependence of density and dynamic viscosity of alternative and commercially available heat-transfer fluids, determining the freezing point and compares the results.
