Ionic fields of various kinds and method of measurement.
Gubani, Ondřej ; Vaněk, Jiří (referee) ; Vognar, Jiří (advisor)
In the air there are positively and negatively charged ions with different mobility and size. The therapeutic effect of negative ions with high mobility is known. High concentration of negative ions occurs in speleotherapic caves. This bachelor thesis introduces the methods of measuring the concentration and mobility of various kinds of ions and their evaluation by spectral characteristics. It verifies the current mirror effect on the ions´ concentration in space. It also examines the effect of different types of ions in living organisms and an appropriate area treatment for the occurrence of negative ions.
Resistivity measuring workplace for composite materials
Kucharčík, Jan ; Barath, Peter (referee) ; Vognar, Jiří (advisor)
This bachelor’s thesis is focused on exploring the characteristics of carbon allotropes. On constructed workspace resistivity of bulk samples will be measured according to the pressure. In conclusion, results of the measurement and proposals to improve the accuracy of the measuring methods are described.

Určení rozdílů relaxačních časů T2 u PMMA gelových elektrolytů
Vognar, J. ; Bartušek, Karel ; Novák, V. ; Vondrák, Jiří
T2 relaxation is complex phenomenon, but at its most fundamental level, it corresponds to a decoherence of the transverse nuclear spin magnetization.
Studium gelových elektrolytů na bázi PMMA a obsahujících ionty Na+ pomocí nukleární magnetické rezonance
Vognar, J. ; Macalík, M. ; Špičák, P. ; Vondrák, Jiří ; Novák, V. ; Krejza, O. ; Bartušek, Karel
Mixture of liquid MMA and PC displays significantly longer relaxation times T1 and T2 than clear solution of NaClO4 in PC. Possibly reason is that the presence of MMA release solvatation of ions Na+ by propylencarbonate.
Elektrodové materiály na bázi uhlíku pro superkapacitory
Dvořák, P. ; Vognar, J. ; Vondrák, Jiří ; Sedlaříková, M.
Research into supercapacitors is divided into two main spheres according their energy storage principles.
