The outer hair cell of the inner ear is believed to be responsible for the high sensitivity and selectivity of mammalian hearing. Molecular motors are generally believed to cause the electrically-driven length change (electromotility) of the outer hair cell. It has been suggested that electrokinetic effects might also play a significant role in electromotility, along with the molecular motors. ...

This paper combines new experimental data for electrokinetic characterization of hydrophobic polymers with a detailed discussion of the putative origins of charge at water-hydrophobe interfaces. Complexities in determining the origin of charge are discussed in the context of design and modeling challenges for electrokinetic actuation in hydrophobic microfluidic devices with aqueous working flui...

UNLABELLED Rapid detection of bacterial pathogens is critical toward judicious management of infectious diseases. Herein, we demonstrate an in situ electrokinetic stringency control approach for a self-assembled monolayer-based electrochemical biosensor toward urinary tract infection diagnosis. The in situ electrokinetic stringency control technique generates Joule heating induced temperature r...

One of the fields where electroacoustic techniques (electrokinetic sonic amplitude, ESA, and colloid vibration current, CVI, are presently available) are expected to be most useful is concentrated suspensions. Here, other electrokinetic techniques, linked to the observation of individual particles, show great limitations. In spite of this, the problem of electroacoustics in concentrated suspens...

The present article reviews the applications of CE in forensic science covering the period from 2001 until the first part of 2005. The overview includes the most relevant examples of analytical applications of capillary electrophoretic and electrokinetic techniques in the following fields: (i) Forensic drugs and poisons, (ii) explosive analysis and gunshot residues, (iii) small ions of forensic...

Abstract In this work, the effects of externally applied axial pressure gradients and transverse magnetic fields on electrokinetic energy conversion (EKEC) efficiency streaming potential nanofluids through a microannulus are studied. The analytical solution for electro-magneto-hydro-dynamic (EMHD) flow is obtained under condition Debye-Hückel linearization. Especially, Green’s function method u...

Our specific objectives are to develop models of ocean sediments that reveal the multi-scale aspects of sediment response. Frequency-dependent acoustic behavior is derived from macroscopic parameters, and these parameters in turn depend on microscopic features that characterize the material. In particular, this project details how electrokinetic phenomena—which have been used in seismology to c...

Electrokinetic techniques have attracted considerable attention due to their competitive advantage in enhancing transport phenomena and remediation of low permeability soils. However, many types low-permeability porous media, such as active clays like bentonite, present a double porosity structure that strongly affects mass transfer processes. In this work, we develop modeling approach simulate...

Overall, investigations about the utilization of electrokinetic technology alone or in combination with other processes have attracted particular attention recent years for remediation soils contaminated heavy metals and organic compounds. This fact is due to its peculiar benefits together capability operating a fine low-permeability matrix. review aimed ascertain most developments on commonly ...
