Ionic Mass Transfer and Concentration Polarization at Rotating Electrode#
Ra te s of ionic mass t rans fe r a t nickel electrodes ro t a t i ng abou t the i r axes in the center of s t a t i o n a r y electrodes were s tudied using the fer r i fer rocyanide couple in a lkal ine solut ions . A general mass t r ans fe r corre la t ion was found to apply equal ly well to dissolut ion ra tes of ro t a t i ng solids and to rates of ionic mass t rans fe r at r o t a t i ng...
متن کاملIonic polarization-induced current–voltage hysteresis in CH3NH3PbX3 perovskite solar cells
CH3NH3PbX3 (MAPbX3) perovskites have attracted considerable attention as absorber materials for solar light harvesting, reaching solar to power conversion efficiencies above 20%. In spite of the rapid evolution of the efficiencies, the understanding of basic properties of these semiconductors is still ongoing. One phenomenon with so far unclear origin is the so-called hysteresis in the current-...
متن کاملCurrent Oscillations in Epoxy-coated Steel at Anodic Polarization
The current oscillatory behavior of epoxy-coated low carbon steel at anodic polarization was investigated in 3,5 % and 0,5 % solutions of NaCl. It was established, that the coated steel may show current oscillations at potentiostatic anodic polarization. The oscillations are of different type, period and amplitude and are more clearly expressed in 0,5 % solution. The presented results might be ...
متن کاملIonic current modulation from DNA translocation through nanopores under high ionic strength and concentration gradients.
Ion transport through nanopores is an important process in nature and has important engineering applications. To date, most studies of nanopore ion transport have been carried out with electrolytes of relatively low concentrations. In this paper, we report on ionic current modulation from the translocation of dsDNA through a nanopore under high ionic strength and with an electrolyte concentrati...
متن کاملOverlimiting current through ion concentration polarization layer: hydrodynamic convection effects.
In this work, we experimentally investigated an effect of the hydrodynamic convective flow on ion transport through a nanoporous membrane in a micro/nanofluidic modeled system. The convective motion of ions in an ion concentration polarization (ICP) layer was controlled by external hydrodynamic inflows adjacent to the nanoporous membrane. The ion depletion region, which is regarded as a high el...
