Relative humidity effects on the electrical properties of silicone ruber
Pušec, Daniel ; Polsterová, Helena (referee) ; Frk, Martin (advisor)
At the beginning, this master thesis briefly describes the principle of semiconductors. It states their types, methods of operation, fields of use, and it interprets the manner of semiconductor devices’ passivation. Then it introduces silicones, their properties and usage. Later on, this thesis summerize air humidity theory and materiál moisturing including mathematical interpretation. Next chapter is devoted to basics of dielectric materials’ behavior. And finally, the last part of this thesis estimates charakteristics of passivation materiál, Dow Corning HIPEC Q1-9205 silicone rubber.

Experimental research of suitability and durability of sealants used in civil engineering
Hanzelková, Martina ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Šlanhof, Jiří (advisor)
The dissertation thesis is focused of the method of testing the building sealnats. This is a summary of the research focused on the evaluation of sealants in interaction with the underlying materials. Attention is focused on the official test methods contained in European technical standards, the benefits of individual methods, their advantages and disadvantages are discussed. Also included are the overall findings of the practical application of the test procedures applied to 10 commercially available industrial sealants on 8 different substrates, including facade lining boards used for lightweight envelope systems. The dissertation thesis contains general conclusions about individual test methods. The research also includes various ways of preparing and conditioning test specimens that simulate different environmental conditions and, in some cases, play a crucial role in the final evaluation of sealants.
