The behavior at the liquid meniscus under the application of a high voltage 4 10Vp-p , high frequency 10 kHz alternating current ac signal is shown to depend very sensitively on the liquid conductivity and the applied frequency. For pure ethanol, after resonance effects become unimportant, the meniscus oscillates and then changes to a growing conical mode with increasing frequency. For ionic-li...

AC electrokinetics is a versatile tool for contact-less manipulation or characterization of cells and has been widely used for separation based on genotype translation to electrical phenotypes. Cells responses to an AC electric field result in a complex combination of electrokinetic phenomena, mainly dielectrophoresis and electrohydrodynamic forces. Human cells behaviors to AC electrokinetics r...

The ionic conduction properties of the technologically important two-dimensional (2D) layered battery material Na2Mn3O7, with exceptional small-voltage hysteresis between charge and discharge curves, have been investigated as a function temperature frequency by an impedance spectroscopy. detailed analyses data in form dc-conductivity, ac-conductivity, electrical modulus, dielectric constant com...
