Joule heating effects in electroosmotically driven microchannel flows (2004, background): “Lately, scientists at Sandia National Lab [3] and Stanford University [4,5] have successfully developed electrokinetic micropumps capable of creating in excess of 20 atm by packing micron sized nonporous silica particles in a 500–900 lm diameter fused silica capillary.”
Recent advances in microscale pumping technologies: a review and evaluation (2008, background): “The packed beads increase the interfacial area available for EO flow, thereby increasing maximum pressure; pressures above 2 MPa have been reported (Zeng et al. 2001).”
Electroosmotic pumps and their applications in microfluidic systems (2009, methodology): “ Zeng et al. (2001, 2002) prepared similar EO pumps by packing 3.5 lm diameter non-porous silica particles in fused silica capillaries with inner diameters ranging from 500 to 700 lm.”
