We report observations of new many-body phenomena in the micro-scale behavior of a suspension subject to a high-gradient strong alternating current (ac) field and shear. Their origin is dielectrophoresis accompanied by the field-induced phase separation [...]
We describe a method for predicting the optimal design of an electrostatic zipper actuator. The shape of the zipping beam and the electrode are optimized to maximize the applied force at a given stroke, while [...]
Electroosmotic flows are extensively employed for fluid transport and sample separation in lab-on-a-chip technologies, capillary zone electrophoresis, and generally in channels and capillaries with length scales on the order of 100 microns or less. Experimental [...]
A complex biophysical process underlying the release of neurotransmitters and hormones from the secretion cells, known as a vesicular exocytosis, is an important mechanism that defines cell signaling and intercellular communication. This phenomenon has been [...]
In this paper we for the first time adopt the model of porous media to simulate the complete course of the formation of monolayers from bead suspensions in a flat microfluidic chamber. The chambers are [...]
As microfluidic devices become more common and more elaborate, it becomes necessary to develop simulation tools that allow the efficient and yet accurate three dimensional time-domain analysis of the behavior of these devices. Detailed time [...]
By applying voltages across a liquid droplet and an underlying dielectric, it is possible to make dielectric forces compete with surface tension forces, and to thereby cause the liquid droplet to change shape. This effect [...]
