Screening Effects in Probing the Electric Double Layer by Scanning Electrochemical Potential Microscopy

R.F. Hamou[1], P.U. Biedermann[1], A. Erbe[1], and M. Rohwerder[1]
[1]Max-Planck-Institut für Eisenforschung GmbH, Düsseldorf, Germany

A computational method is developed to study probing the electric double layer by Scanning Electrochemical Potential Microscopy. The model is based on a modified Poisson- Boltzmann equation, which takes into account steric effects. We investigated the effect of metallic apex protrusion ... En savoir plus

Multiphysics Analysis of a Thermo-Acoustic MHD Inductive Generator

R. Forcinetti [1], S. Carcangiu [1], A. Montisci [1],
[1] DIEE, University of Cagliari, Cagliari, Italy

Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus

Tunable MEMS Capacitor for RF Applications

H. S. Shriram[1], T. Nimje[1], D. Vakharia[1]
[1]BITS Pilani, Rajasthan, India

Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the ... En savoir plus

[2] Institute of Biology, Chair of Biophysics, University of Rostock, Germany

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a ... En savoir plus

Simulation of Thermal Breakdown in a Multi-Layered Stack of Dielectric Elastomers

L. R. Madsen [1], O. Hassager [1], A. L. Skov [1],
[1] Danish Polymer Centre, DTU Chemical Engineering, Lyngby, Denmark

Dielectric elastomers are a promising group of smart materials, which finds application within many fields such as soft robotics, wave-energy harvesting, and loud speakers. A dielectric elastomer consists of a thin, stretchable polymer film sandwiched between two compliant electrodes. ... En savoir plus

Quasielectrostatic Induction on Stationary Vehicles under High Voltage Power Lines

J. Leman[1]
[1]POWER Engineers, Hailey, ID, USA

The National Electrical Safety Code (NESC) requires that high voltage power lines in the U.S. be designed to limit electrostatic effects on nearby equipment. An example is that of a large vehicle underneath a transmission line. The tires insulate the vehicle’s body from ground. If a ... En savoir plus
