摘要: The occurrence of reactions at boundaries between adjacent miscible but unmixed aqueous streams coflowing in a microfluidic channel structure has been studied by simulation the diffusion potentials that develop two electrolyte and measurement effects ion complexation on potentials. consisted Y-shaped microchannel with off-chip electrodes immersed reservoirs connected capillaries to Y-microchannel. time-dependent, one-dimensional Nernst−Planck equation employing electroneutrality condition was solved numerically calculate established boundary streams. Under experimental conditions (channel length width, flow rate) employed, it shown use Henderson appropriate. It also cross-channel potential remained constant from entrance chann...
