Rotating ring-disk method, effect

Are Rotating Disk with Ring Electrodes Still Useful in the Twenty-first Century When the rotating disk electrode was first used, it was the 1960s since that time, many new methods for measuring electrode reactions (above all, spectroscopic ones, e.g., those in Section 7.5.15), have been invented. Furthermore, microelectrodes have made it possible, in effect, to reduce 5 by as much as 1000 times compared with that in a still solution, so that one of the uses of the rotating disk...
