Figure 2.
(A) Bubble formation and detachment at 35 mA (≈179 mA cm−2 geo) from 1000 to 2900 RPM as observed by fluctuations in the uncompensated potential, (B) short manual rotation increases to show bubble release with 1000 RPM, 1500 RPM and 2500 RPM as stable rotation rates. Current spikes that hit the 2500 RPM LSV are induced by a brief increase in rotation rate (and are marked with an asterisk); smaller oscillations are caused by spontaneous bubble releases. LSVs are 85 % iR compensated to clearly show the vertical current spikes with bubble releases.
