Electrochemical study of novel materials for energy conversion application
Novčić, Katarina ; Rees, Neil (referee) ; Kim, Daewoo (referee) ; Pumera, Martin (advisor)
Slibnou alternativou k řešení současné energetické a environmentální krize spočívá v využití elektrochemického rozkladu vody pomocí reakce na vývoj vodíku (HER). Proto existuje naléhavá potřeba zkoumat a vyvíjet nové elektrokatalyzátory pro aplikaci přeměny energie a HER jako součást tohoto procesu. Různé nové materiály se ukázaly jako slibní elektrokatalyzátory pro HER. Mezi nimi mají dvourozměrné (2D) materiály, jako jsou dichalkogenidy přechodových kovů (TMD), MAX fáze a MXeny, velkou pozornost díky svým slibným elektrochemickým vlastnostem. Navíc tisk ve 3D otevřel cestu k rychlému prototypování a výrobě elektrodových zařízení, a jejich kombinace s různými 2D materiály zůstává výzvou. Tato práce se zabývá elektrochemickým studiem různých nových materiálů pro aplikace přeměny energie a čisté výroby vodíku. Představuje studium makroskopické a mikroskopické elektrochemické výkonnosti upravených 3D-tisknutých nanouhlíkových elektrod a elektrokatalyzátorů TMD, MAX fáze a MXen. Makroskopická elektrochemická aktivita je studována tradičními technikami, jako je voltametrie, poskytující informace o průměrném elektrochemickém výkonu materiálů. Kromě toho je jejich mikroskopická elektrochemická aktivita prováděna skenovací elektrochemickou mikroskopií (SECM), která poskytuje vhled do místních rozdílů v elektrochemické aktivitě materiálů a informace o distribuci a rovnoměrnosti HER aktivních míst na površích materiálů. Tato práce má široké důsledky pro obecné porozumění elektrokatalytickému výkonu nových 2D materiálů, což je důležité pro jejich budoucí vývoj jako elektrokatalyzátorů.

Project for an automouse source of electrical energy
Vinkler, Stanislav ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
Purpose of the thesis is enlarged the theory about potential utilization of an autonomous (autonomic) electric power supply used for a family house. Forepart will dealt with description of the resources in accordance with conversion of different kinds of energy to electric power. There will be always given the principle of the power generation as well as a list of main components of the system for each single source. Second part will be focused on generator output assessment of the autonomous source to ensure the power supply for the model family house. There will be my own design of the autonomous sources namely a project of a small hydropower plants and a project of a cogeneration unit in the third section of the thesis. The last part is aimed at the techno-economical evaluation of the engineered sources.

New approaches to the use of energy of water waves
Novotný, Vojtěch ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
Bachelor´s thesis deals with topic of utilization the energy of sea waves. Mainly describes existing devices transforming this energy into electricity, their division and on what principle they work. Thesis also contains description of sea waves. In the next part, the author designs and describes his own devices converting sea wave energy into electricity. If there is a similar device that is patented and exists author process a patent search to find out.
