In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the relative location of nucleus with respect to the electrical field, we found that the observed cell rotation was ...

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of the electric field. DEP is caused by polarization of the DNA particle. Two different electrode geometries ...

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised in radial direction is generated. This radial field interacts with metallic tube and generates ...

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix methods. The CDLE technique is based on the fact that the capacitance of the electric double layer (EDL) ...

It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present work, these solutions have been calculated for the first time with COMSOL Multiphysics.

We present a simplified 3D model that simulates the operation of a linear microscale integrated ion trap. It employs a set of metalized electrodes, which are formed on top of an insulator layer on silicon substrate. The confinement in all three dimensions is provided by the application of the specific AC and DC voltages to the corresponding trap electrodes. The distribution of the trapping ...

Since the 1980s, the accelerating effect of electromagnetic fields on bone regeneration is used to treat complicated fractures and bone diseases. At the University of Rostock, an electrostimulative hip revision system is developed, basing on the method of Kraus-Lechner. This method requires an electric fields between 5 and 70 V/m. The bone used for the simulations consisted of two homogenous ...

In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not only are these additional domains result in an increased number of degrees of freedom which are strictly ...

After spinal cord injury (SCI) the functions of the lower urinary tract are often disrupted and may have fatal consequences for the patient. It has been shown that using a transrectal probe developed by Craggs et al., through conditional transrectal stimulation of pudendal nerve, it is possible to treat hyperreflexia in some of the SCI patients. To maximise the efficacy of this type of ...

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis . However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because the electric field induced by the binding of biomolecule is partially screened on length-scales larger than the ...
