Thermal aging of nanocomposites
Janíček, Martin ; Rozsívalová, Zdenka (referee) ; Polsterová, Helena (advisor)
This thesis deals with issues of properties of nanocomposites and it´s heat aging. In the first part there are theoretically analysed some of the basic therms connected with nanocomposites. Also there are outlined basic methods of production of these matherials. The most important is specification of individual properties when bigger attention is gived to electrical properties. Practic part deals with heat aging of samples of nanocomposites filled with nanoparticles Al2O3. There was monitored impact of time of aging on values of internal resistance, dissipation factor and relative permitivity.

Resistance to freezing and thawing of hydraulically bound mixtures to roads
Švantner, Lukáš ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The theoretical part of this master’s thesis contain comparing the methods of endurance hydraulic bound mixtures of concrete recycles against influence of water and freeze in Czech republic and some other states of The European Union. The practical part is dedicated about laboratory testing concrete recycles with mixtures of binders and its endurance against the water and freeze cycles in Czech republic. In made rollers is compared the strength in pure compression with the strength in pure compression after freezing cycles. From the results of the exams is considered about suitability of using these hydraulic bound mixtures to road construction depending on the kind of use binder, amount of the binder and water. Results of this thesis will be used to revision of national postscript of technological norm ČSN 73 6124-1.

Development of a thermal insulating material designed for use with high temperature
Dokoupil, Martin ; Frajt, Daniel (referee) ; Drochytka, Rostislav (advisor)
The work deals with the development of a new thermal insulation material that contains a secondary raw materials or waste. It is an insulating material with the requirement of resistance to high temperatures - 200 ° C and 500 ° C. Type of material is determined by the way of reducing density - direct and indirect. Direct is achieved by adding lightweight aggregates, indirect is achieved by gas evolution through chemical reaction and the subsequent incorporation of gas into the structure of the material. This thesis is part of the MPO TIP č. FR-TI 2/340 project.

Binders for supercapacitors electrodes
Gottwald, Tomáš ; Dvořák, Petr (referee) ; Sedlaříková, Marie (advisor)
This work deals with the issues of useing binders for supercapacitor electrodes and optimizing the technological process for their production. The work focuses on optimizing the amount of binder used in order to acheive the most capacity. The methodology consists of creating an appropriate experimental electrode and subsequent measuring its associated capacity with AutoLab. This aproach leads to creating grafs which show the dependencies of capacity on the amount of binder used.
