Carbon based electrodes for supercapacitors
Moncoľ, Maroš ; Kunovjánek, Miroslav (referee) ; Dvořák, Petr (advisor)
This master thesis deals with supercapacitors based on electrical double layer and proper carbon electrodes for this type of supercapacitors. In theoretical part of work is described theory of supercapacitors, energy storage principles and their properties. In the next part are described carbon materials, their properties and electrochemical methods of measurements that we used. In the experimental part is described preparation of electrodes, results and conclusion.

Effect of Plasma Oxidation of Carbon Working Electrode on Its Electrochemical Response
Koporec, Lukáš
Screen-printed electrochemical sensors are very perspective because they are much smaller than common electrodes used in electrochemistry, portable, ecological and can be very easily modified in order to increase their sensitivity and selectivity for specific analytes. In this study, plasma treatment was used to modify the carbon working electrode of a screen-printed threeelectrodes system. Plasma treatment was performed using RF plasma discharge in argon/oxygen atmosphere. The plasma modified electrodes exhibited considerable enhancement in electrocatalytic activity towards studied electroactive compounds.
