Bones implants based on Fe
Hávová, Mariana ; Vondrák, Jiří (referee) ; Sedlaříková, Marie (advisor)
This thesis refers to Fe-based biodegradable materials and their potencial aplications in medicine, especially as temporary bone implants. This work generaly summaries aplications of biomaterial in medicine with more interest kept on biodegradable materials and their in-vivo corrosion. The experimental part refers to conduction of porous Fe-based materials with silica addition. The structure of prepared specimens is identified by EDX and XRD analysis. The imersion test and electrochemical studies were conducted to observe corrosion behaviour with respect to different concentration of silica. Potenciodynamic curves were obtained to determine corrosion potencial and corrosion current density of prepared samples.

Ionic liquids for electrochemical power sourcees
Korec, Pavol ; Máca, Josef (referee) ; Sedlaříková, Marie (advisor)
Bachelor thesis Ionic liquids for electrochemical power sources deals with the measurement of electrical properties of ionic liquids, their conductivity and potential window, to broaden the knowledge of their optional use as lithium – ion battery electrolytes. The theoretical section of the work deals with the properties and usage of ionic liquids, structure and functionality of lithium – ion batteries and measurment of electrochemical impedance spectroscopy a cyclic voltammetry. The practical section of the work describes the process of measuring the conductivity and potential window of ionic liquids, observes the changes made to the electrical properties of the samples by adding LiBF4 salt and propylencarbonate solvent and summarizes results.

Biodegradable metal materials for bone tissue prosthetics
Panáková, Olga ; Vondrák, Jiří (referee) ; Sedlaříková, Marie (advisor)
This paper is focused on use of metal materials as a bone replacement. For coherence of this text is necessary theoretical preamble which is consisting of describing metal properties, aimed particularly at corrosion, valuation methods of disposition to corrosion and mainly corrosion itself. This paper also includes description of techniques of preparation, which involves selection of material and its procession. Furthermore there are stated results of experiments. Those are amended with pictures.

Bones implants based on Fe and Mg
Košíček, Adam ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
This paper work deals with properties of metallic biomaterials in terms of their suitability for use as a temporary metal implants. The work focuses on biodegradable materials based on iron and suitable alloying elements, which would create a perfect implant. A part of this work describes procedure of creating biodegradable metallic samples with alloying element Magnesium and measuring the corrosion rates. There are a few theoretical chapters concerning permanent implants, function and composition of human bones, iron and magnesium in human body and biodegradable materials.

Gel polymer electrolytes with lower flammability
Zítka, Jan ; Musil, Michal (referee) ; Sedlaříková, Marie (advisor)
This work discusses the research and development of gel polymer electrolytes and their use. It also deals with problems of characterization and optimization of technological process of polymer gel electrolytes with low flammability. Furhermore, this work deals with how to assess such electrolytes and what their properties. The main focus of work is a comparison of solvents contained in the gel polymer electrolytes and the creation of such a gel, which when compared to mechanical, electrical and physical properties will have the best results.
