Oxygen reduction via grain boundary transport in thin film platinum electrodes on yttria stabilized zirconia
Model-type sputter deposited platinum microelectrodes with different grain sizes were investigated on single crystalline yttria stabilized zirconia (YSZ) by means of impedance spectroscopy. Measurements on single platinum microelectrodes could be continuously performed for > 100 h and from 250 to 800 °C without losing contact. From the temperature dependence, two parallel reaction pathways for ...
متن کاملAmperometric Oxygen Electrodes
Although the Winkler method is very precise when performed with strict control of pH and iodine concentration, it is still susceptible to errors. For example, ions such as Fe2+ and SO3-, suspended solids, and some organics can produce gross inaccuracies. There have been numerous modifications of the method over the years to compensate for its shortcomings (2). Besides the errors inherent in the...

متن کاملAmperometric thick-film strip electrodes for monitoring organophosphate nerve agents based on immobilized organophosphorus hydrolase.
An amperometric biosensor based on the immobilization of organophosphorus hydrolase (OPH) onto screen-printed carbon electrodes is shown useful for the rapid, sensitive, and low-cost detection of organophosphate (OP) nerve agents. The sensor relies upon the sensitive and rapid anodic detection of the enzymatically generated p-nitrophenol product at the OPH/Nafion layer immobilized onto the thic...
متن کاملNew Hydrodynamic Electrochemical Arrangement for Cadmium Ions Detection Using Thick-Film Chemical Sensor Electrodes
Miniaturization and integration of chemical devices into modules that are dimensionally comparable with electronic chips (Lab on Chip) is nowadays developing worldwide. The aim of our work was to suggest and optimize the best conditions for fabrication of TFT sensor due to its sensitivity and low experimental deviations. New electrochemical analytical device was developed to ensure certain know...
