Capillary electrokinetic separation techniques offer high efficiency and peak capacity, and can be very useful for the analysis of samples containing a large variety of (unknown) compounds. Such samples are frequently met in impurity profiling of drugs (detection of potential impurities in a pharmaceutical substance or product) and in general sample profiling (determination of differences or si...

Electrokinetic decontamination and extraction have been proven to be one of the most viable, cost effective and emerging techniques in removing contaminants, especially heavy metals from soils for about last five decades. Basic concepts and an overview of the electrokinetic extraction processes and their potential applications in geotechnical and geoenvironmental engineering have been reviewed ...

Electrokinetic techniques continue to play a leading role in technologies ranging from nanoparticle characterization and directed electronics assembly to micropumps and micromixers to biosensors and DNA sequencing. In this session, we invite submissions related to the development of new technologies in any of these areas, from both the fundamental and applied perspectives. Suitable topics inclu...

A novel methodology for designing microfluidic channels for lowdispersion, electrokinetic flows is presented. The technique uses simple trigonometric relations that apply for ideal electrokinetic flows, allowing channels to be designed using a hand calculator. Nloreover, channels are easily constructed using common planar manufacturing techniques. Close agreement is observed for particle path l...

Electrokinetic instability refers to unstable electric field-driven disturbance to fluid flows, which can be harnessed to promote mixing for various electrokinetic microfluidic applications. This work presents a combined numerical and experimental study of electrokinetic ferrofluid/water co-flows in microchannels of various depths. Instability waves are observed at the ferrofluid and water inte...
