Oxidation of methanol in alkaline solution was observed at approximately 0.245 v, which is much less positive than that on an unmodified polycrystalline gold electrode.
The investigators measured oscillatory brain activity, the event-related late-positive potential (LPP), and self-reports of anger intensity during picture viewing.
The self-adaptable control of output voltage could be realized under certain range by adding a APFC in ultrasonic generator and adjusting voltage feedback network with digital potentiometers.
