Voltage contrast method in ESEM
 Krňávek, Martin ; Čudek, Pavel (referee) ; Jirák, Josef (advisor)
This work contains theoretical description of basic features and principles of electron microscopy, with focus on environmental scanning electron microscopy. It describes function of the microscope, interactions that takes place after collision of electron pack with a sample, mainly it describes creation of back reflected electrons and secondary electrons and methods of voltage contrast. The practical part focus on voltage contrast issue by observing decomposition of electric potentials on surface of semiconductor devices and it establishes ideal working conditions for observing voltage contrast by scintillation detector of secondary electrons.

Regional energetic waste exploitation
 Krňávek, Martin ; Putna, Ondřej (referee) ; Bébar, Ladislav (advisor)
The master’s thesis deals with technologies for energy utilisation of waste with annual treatment capacity approximately from 10 to 50 kt/year and their application in regions of the Czech Republic. In the first part of the thesis the results of heat consumption analysis in seven regions of the CR are introduced while in two selected regions a production of waste was analyzed too. The main part deals with the design of technological solution of waste-to-energy plant with medium capacity and its integration to specific conditions of the two selected regions. Alternatives of combined heat supply were assessed from waste-to-energy plant as well. A basic economic analysis that contains the estimates of incomes and capital expenditures and operating expense is a part of this thesis too.

Up-to-date technology for energy utilisation of biomass and waste
 Krňávek, Martin ; Frýba, Lukáš (referee) ; Kropáč, Jiří (advisor)
The bachelor‘s thesis deals with technologies for energy utilisation of biomass and waste. The introductory part is dedicated to biomass, its division and sources of biomass suitable for thermal treatment. The main part describes and compares technological units for energy utilisation of biomass, which is important for the Czech market. Furthermore there is described selected technologies for flue gas cleaning suitable especially for thermal treatment of waste. A basic design calculation of technological unit fired with wood chips for combined heat and power production is included here.
