The onset potential of oxygen reduction in alkaline fuel cells
Vondrák, Jiří; Velická, Jana; Barath, P.; Sedlaříková, M.; Kazelle, J.; Kliment, J.
2006 - English
The onset potential of oxygen reductin was defined as the potential, below which the electroreduction of oxygen is possible. This value can be used for the comparison of various electrocatalysts. The method was tested on several carbonaceous materials onto which the same amount of platinum was deposited. Byl definován potenciál počátku redukce kyslíku jako potenciál, pod kterým začíná elektrochemická redukce kyslíku na katalytických elektrodách s cílem nalézd parametr posuzující výkonnost elektrokatalyzátoru. Metoda jeho výpočtu byla testována na katalyzátorech na bázi platiny nanesené na různých typech uhlíkatého nosiče.

Electron paramagnetic (spin) resonance spectroscopy (EPR/ESR) of free radicals and antioxidants in plants
Stopka, Pavel; Křížová, Jana
2006 - English
We studied reactive oxygen and nitrogen reactive species (ROS, RNS) using EPR spectroscopy in plants. We proved the antioxidation capacity of moravian wines and interaction of humic acid complexes with selected paramagnetic transition metals. Studovali jsme reaktivní kyslíkové a dusíkové částice (ROS, RNS) metodou EPR spektroskopie v rostlinách.
