Flow birefringence in complex fluids has long been viewed as a noninvasive probe for stress fields based on the stress-optic law. Experiments reveal that this law fails in unsteady flows, with ...
Abstract: In this paper, the mechanism of convex corner (CC) undercutting of Si/sub {100}/ in pure aqueous KOH solutions is revisited by proposing the step-flow model of 3-D structuring as a proper ...
