Metallization of technical plastics for lightweight traffic components with reduced fuel consumption
Sanetrníková, Dominika ; Boušek, Jaroslav (referee) ; Šimůnková, Helena (advisor)
The beginning of this thesis is dedicated to polymeric materials, which include plastics an composites. Plastics are shortly divided into two groups, thermoplastics and thermosets. The following part is the use of plastics and composites in traffic industry and briefly this work focuses on techniques of recycling of this materials. This work also focuses on the techniques of thin film deposition, electroless plating, electrodeposition as well and plating in the vacuum environment. special techniques of thin film deposition are also mentioned shortly. The coatings of polymer including cleaning and surface activation is introduced using various techniques including plasma treatment. The surface treatment of polyetheretherketone (PEEK) is included too. The final part describes performed experiments and discussion of results.

3D printed antenna with dielectric lens for free-space material characterization method
Horník, Milan ; Láčík, Jaroslav (referee) ; Kaděra, Petr (advisor)
This bachelor´s thesis deals with the free space setup for material permittivity characterization. The workplace includes two horn antennas, two dielectric lenses and sample holder. The work deals with the characteristic properties of materials such as permittivity and permeability. Further, the methods used to determine permittivity are discussed. The next part of the work is focused on a theoretical analysis of the design of a broadband horn antenna with a dielectric lens. The chapter 3D printing and surface treatment deals with the issue of 3D printing and the possibility of applying a conductive layer on the plastic components. The following section presents the calculated and simulated results performed in CST Microwave Studio. In the next chapter, mechanical construction and measurement setup fabrication are discussed. In the end, the achieved results are evaluated.

Plastic plating
Čermák, Jan ; Kubíček, Jaroslav (referee) ; Žák, Ladislav (advisor)
The perspective of the production of plastic parts has helped to spread the metallization of these parts on a large scale. Whether a coating is functional or just decorative. This bachelor thesis presents a comprehensive study, analysis, evaluation and comparison of the possibilities of creating metal coatings on plastic materials. The thesis deals with galvanic, chemical, vacuum and special methods of plating. For all the mentioned methods of plating, the technological procedure, equipment for plating, evaluation of individual methods and analysis of the use of plated plastic parts are given.

The practical aspect for evaluation of waste-water from metal plating
Válek, Roman ; Vávrová, Milada (referee) ; Doležalová Weissmannová, Helena (advisor)
The Galvanic Plating Technology is used by many branches of modern industry. Sizeable amounts of waste water are an integral part of plating technologies. It contains a versatile spectrum of chemical substances hazardous to the environment. This work focuses on monitoring the level and nature of waste water pollution resulting in primary production. Several indicators were selected to appreciate the quality of the effluent, which were defined according to the procedures. The possibility of quality monitoring process based on values of pollution was discussed after evaluating the results.

Designing novel catalyst loaded electrode materials towards electrochemical sensing to energy applications
Kandambath Padinjareveetil, Akshay Kumar ; Escarpa, Alberto (referee) ; Vidal, Salvador Pané (referee) ; Pumera, Martin (advisor)
Exponenciální nárůst potřeby energie spolu s rostoucími nároky na zdravotnický sektor způsobuje velká rizika pro přežití lidstva na Zemi. V současné době probíhá intenzivní výzkum s cílem nalézt ideální řešení k překonání těchto globálních výzev. Využití elektrochemických energetických technologií je velmi žádané pro zmírnění rostoucích energetických požadavků ve spojení s výrobou novějších elektrokatalyzátorů, které jsou levné, účinné a odolné pro využití takových zařízení pro komerční aplikace ve velkém měřítku. Ačkoli se opakovaně studuje několik katalytických materiálů, existuje potřeba dalšího výzkumu katalyzátorů. V této studii jsou představeny nové techniky přípravy katalyzátorů pro vývoj aplikací těchto katalyzátorů pro výrobu vodíku a amoniaku. S rozšiřujícím se rozsahem technologie 3D tisku je také podrobně diskutována výroba elektrokatalyzátorů prostřednictvím této technologie s důrazem na elektrokatalytické aplikace, jako je výroba vodíku, syntéza amoniaku a redukce oxidu uhličitého. Kromě katalýzy tato práce také hodnotí potenciální možnosti využití technologie 3D tisku pro biomedicínské aplikace, jako jsou elektrochemické sensory. V sourhnu, práce si klade za cíl výzkum pokročilých elektrokatalůyzátorů spolu s poskytnutím vhledu do navrhování a konstrukci materiálů aktivních elektrod pro přeměnu energie a aplikace elektrochemických sensorů.
