Effects of Memories of Polarization Interactions during Particle Transport Induced by One Gradient AC Electric Field

Shen Y., Tada S., Qiu Z., The City College of the City University of New York and New York Center for Biomedical Engineering, US

On the Nanotech 2008 in Boston, we reported our experimental observations of the particle instability and island-like structures in the suspension of poly alpha olefin particles and corn oil when the suspension was exposed to [...]

Concentration Tuned Interactions and Structures in One Gradient AC Electric Field

Qiu Z., Tada S., Shen Y., City University of New York, US

External field-controlled particle structure growth is an active area in micron- or nano- material assembly. We will present preliminary experimental results about how to use particle concentration to tune interactions and structures in one gradient [...]

External Field Induced Non-Uniform Growth of Micron Composite Materials in Insulating Liquid: Experimental and Simulating

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

Numerical simulation is performed of motion and cluster formation of particles in a flowing suspension of particles in corn oil through a 60x120x3.0mm chamber with a spatially periodical electrode array. The chamber is rotated to [...]

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 [...]
