“…Several recent papers have addressed the above aspects specifically, and in particular have compared SA responses in quiescent and various hydrodynamic or convective conditions (e.g., stirring the solution [60][61][62], vibrating the microelectrode [63], microwave or thermal heating [64,65a-b] of the electrode). It was found that mechanical stirring of the solution was in any case beneficial, but was relatively small at disk and sphere caps (i.e., up to 1.2-1.5-fold enhancements for a hemisphere of 12.5 μm radius and a disk of 15 μm ra- dius, at 300-400 rpm [60,61]), and larger with cylindrical microelectrodes. In addition, it was found that the longer the microwire the greater the effect (i.e, up to 4-fold improvement for a microwire of 2.5 μm radius at 3000 rpm [63]).…”
