Secondary Microflows in Electrokinetic Transport with Hydrodynamic Slippage Effect

Kim K.S., Chun M.-S., Byun Y.T., Woo D.H., Korea Institute of Science and Technology (KIST), KR

The curved microchannel is frequently encountered in the lab-on-chips because it provides a convenient way for increasing channel length per unit area. The behavior of electrokinetic flow with curvature-induced secondary motion was explored based on [...]

Electrothermal blinking vortices for chaotic mixing

Kauffmann P., Loire S., Mezic I., UCSB, US

At microscale, an efficient mixing is a keystep which dramatically accelerates bio-reactions. This paper presents an experimental and theoretical study of electrothermal chaotic mixing. To do so, asymmetric vortices are blinked to perform time dependant [...]

Electrokinetic Flows in Highly Charged Micro/Nanochannel with Newtonian Boundary Slip Condition

Chun M.-S., Yun J.H., Kim T-H., Korea Institute of Science and Technology (KIST), KR

The physics of micro/nanofluids has become an area of intense interest both scientifically and technologically. The long-range nature of viscous flows and the small dimension inherent in confined spaces imply that the influence of boundaries [...]

Autonomous Nanoscale Motion Through Catalysis

Sen A., Pennsylvania State University, US

Nanoscale moving systems are currently the subject of intense interest due in part to their potential applications in nanomachinery, nanoscale assembly, robotics, tribology, fluidics, and chemical/biochemical sensing. Most of the research in this area has [...]

Simulation of Electrokinetic Flow and Analyte Transport in Nano Channels

Feng J.J., Krishnamoorthy S., Wang G.W., Sundaram S., CFD Research Corporation, US

This paper demonstrates the electrokinetic flow and transport of charged and neutral analytes in nanochannels by solving full system of governing Poisson-Nernst-Planck equations without any assumptions. The issues related to the spatial and time scales [...]

Electrokinetic Instabilities and Sample Stacking

Lin H., Oddy M.H., Santiago J.G., Stanford University, US

Microfabrication technology has enabled the application of electrokinetics as a method of performing chemical analyses and achieving liquid pumping in electronically-controlled microchip systems with no moving parts. This talk reviews progress at Stanford in the [...]
