Field-aligned currents and ionospheric parameters deduced from EISCAT radar measurements in the post-midnight sector [PDF]

, 2002
International audienceAttempting to derive the field-aligned current (FAC) density using the EISCAT radar and to understand the role of the ionosphere on closing FACs, we conducted special radar experiments with the EISCAT radar on 9 October 1999.

Electrical Conductance of Charged Nanopores

ACS Omega, 2022
A nanopores's response to an electrical potential drop is characterized by its electrical conductance, \tilde{G}. It has long been thought that at low concentrations, the conductance is independent of the electrolyte concentration, \tilde{c}_0, such that \tilde{G} ~ \tilde{c}_0^0. It has been recently demonstrated that surface charge regulation changes

Electrohydrodynamics and dielectrophoresis in microsystems: scaling laws [PDF]

, 2003
The movement and behaviour of particles suspended in aqueous solutions subjected to non-uniform ac electric fields is examined. The ac electric fields induce movement of polarizable particles, a phenomenon known as dielectrophoresis.

The electric field in northern England and southern Scotland: implications for geomagnetically induced currents. [PDF]

, 2006
Magnetotelluric (MT) data, in the form of MT tensors, are used to estimate directly the size and spatial distribution of the electric field in northern England and southern Scotland with the aim of predicting the flow of geomagnetically induced currents ...
