Micron Particles Segregation in Lower Electric Field Regions in Very Dilute Neutrally Buoyant Suspensions

Qiu Z.Y., Shen Y., Tada S., Jacqmin D., The City College of New York, US

We use a spatially periodical electrode array in a fluid chamber to generate a high gradient electric field. Neutrally buoyant poly alpha olefin particles in corn oil in the chamber are transported to the lower [...]

Field-induced Dielectrophoresis and Phase Separation for Manipulating Particles in Microfluidics

Bennett D.J., Khusid B., James C.D., Galambos P.C., Okandan M., Jacqmin D., Kumar A., Qiu Z., Acrivos A., New Jersey Institute of Technology, US

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 [...]
