The influence of soft, hydration-mediated ion-ion and ion-surface interactions on the differential capacitance of an electric double layer is investigated using Monte Carlo simulations and compared to various mean-field models. We focus on a planar electrode surface at physiological concentration of monovalent ions in a uniform dielectric background. Hydration-mediated interactions are modeled ...

In this work we report on progress in the development of models for a Micro-Pulsed Plasma Thruster (μPPT) and its exhaust plume. As a working example we consider a μPPT developed at the Air Force Research Laboratory. This is a miniaturized design of the axisymmetric PPT with a thrust in the 10 μN range that utilizes Teflon as a propellant. The plasma plume is simulated using a hybrid fluid-PIC-...

This paper deals with the measurement of AC corona inception voltage, Vincp, at the tip of a rod electrode using a hemispherically-capped rod-plane electrode configuration for various rod radii with a short air gap. Effects of atmospheric pressure and temperature variation on Vincp are investigated experimentally. An empirical equation for the field form factors of the hemispherically cappe...

Particle-covered droplets are used in several fundamental studies and practical applications. For many applications, it is important to understand the mechanics of these subjected induced external stresses, such as an electric field (E-field). Several research groups have studied deformation stability uniform E-fields. However, behavior particle-laden nonuniform E-fields inadequately reported. ...

in this article electrochemical determination of captopril at the surface of the platinum coated nanoporous gold film (ptnpgf) electrode is reported using the cyclic voltammetry and amperometry. for the preparation of ptnpgf, the surface of npgf electrode was covered with cu layer using underpotential electrochemical deposition (upd).afterward, the copper layer is replaced with platinum ions vi...

Transcranial stimulation encompasses all non-invasive brain stimulation techniques where electrical current is generated or induced in the brain for experimental or therapeutic purposes using scalp electrodes or magnetic coils. Each modality (e.g. transcranial current stimulation, cranial electrotherapy stimulation, transcranial magnetic stimulation, electroconvulsive therapy) produces a spatio...
