Massive online open course (MOOC)
Všetíček, Adam ; Wolák, Radim (advisor) ; Šírová, Tereza (referee)
The MOOC (Massive Open Online Course) bachelor thesis deals with the educational potential of media, focusing on a modern phenomenon in education - the massive open online courses. It traces their development, evaluates the benefits of online learning and identifies the differences between graduates of the massive open online courses in the Czech Republic and abroad, using the questionnaire method. Moreover, the paper documents what preceded the massive online courses, through the development and defining of distance education, e-learning and lifelong education. The readers are also made aware of the advantages and disadvantages of the massive open online courses in comparison to traditional education. The conclusion then summarizes all our findings and research results, as well as it outlines the possibilities of further development of the MOOC. Powered by TCPDF (www.tcpdf.org)
Deposition of magnetic nanostructures using EBID and optimalization of their chemical composition and morphology
Vyroubal, Ondřej ; Kolíbalová, Eva (referee) ; Kolíbal, Miroslav (advisor)
This master's thesis deals with deposition of cobalt nanostructures using Electron Beam Induced Depositon (EBID). The thesis firstly describes theoretical background regarding EBID. In the following experimental part, the deposition process is optimized via analysis of exposition parameters and their influence on the final shape of nanostructures. These are analyzed via Atomic Force Microscopy (AFM). Optimized exposure parameters are then applied to the deposition of functional 3-dimensional nanostrucutres. In particular, the deposition of cobalt spheres. The elemental composition is analyzed by the means of element composition using Energy-dispersive X-ray Spectroscopy (EDX) and the nanostructures of desired morphologies are studied with Magnetic Force Microscopy (MFM) and Magneto-Optical Kerr Microscope).
The influence of ionic liquids on functional elements in lithium-ion batteries
Meščánková, Veronika ; Sedlaříková, Marie (referee) ; Máca, Josef (advisor)
This thesis deals with ionic liquids, their conductivity and the action of the electrode materials, separators and current collectors. The theoretical part is focused on the properties of ionic liquids, Li-ion batteries, corrosion, conductivity and analysis elements. The practical part is focused on the production of graphite electrodes, measuring the conductivity of ionic liquids with different parts of lithium – ion battery and measuring the potential window. Also, there is the effect of ionic liquids described in these parts.
Deposition of Cobalt nanodots using EBID and optimalization of their chemical composition and morphology
Vyroubal, Ondřej ; Průša, Stanislav (referee) ; Kolíbal, Miroslav (advisor)
This bachelor's thesis deals with deposition of metal nanostructures by EBID. Several deposition parameters are described and it is shown how they infuence the process of deposition. The atomic composition of cobalt structures was veried by EDX. Additionally, the optimized geometries of nanostructures for future practical applications are shown as well.
