  author={Hsien Chen Ma},
Diffusioosmosis of an electrolyte solution is the electrokinetic flow involving a tangential concentration gradient of the electrolyte that interacts with a charged wall. Electrolyte solutions with a concentration gradient of order 1 M/cm along solid surfaces with a zeta potential of order kT/e (~25 mV; e is the charge of a proton, k is the Boltzmann constant, and T is the absolute temperature) can flow by diffusioosmosis at a velocity of order μm/s. The fluid motion caused by diffusioosmosis… CONTINUE READING
