The Movement of Molecules in Non-Uniform Electric Fields
Australian Journal of Chemistry, 1961The motion of polar molecules as solute in a non-polar solvent, under the action of a non-uniform electric field, has received little attention. The theory of such motion has been developed and an experimental concentration separation of 25% achieved between p-nitroaniline and carbon tetrachloride from solution.

Drift Instability in a Non Uniform Electrical Field
Fusion Technology, 1999The influence of a non-uniform electrical field, perpendicular magnetic on drift instability was studied by Sanuki et al. 1,2 They have shown, that the drift instability is stabilized at a rather large gradient of an electrical field. This result was received by means of the analysis of an integral wave equation, which describes the plasma ...

Modeling molecular response in uniform and non-uniform electric fields
The Journal of Chemical Physics, 2013The response of a molecule to an electric field E, often a model of environment, can be expressed in terms of a sum of power series expansions. We investigate the accuracy and limits of applicability of this expression using one-, two-, and three-dimensional models of the hydrogen-bonded complex, ClH:NH3.

Electric field simulation in a non-uniform field dielectric system
[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002The charge simulation method (CSM) is used to compute potential and electric field distribution in a 'hyperboloid-plane' electrode system. Electric field enhancement along the axis of the hyperboloid and within the dielectric is calculated at various interelectrode spacings and with various tip radii.

Corrosion Behavior of Aluminum in Non‐Uniform Electric Fields
Journal of the Chinese Chemical Society, 2001AbstractThe present paper discusses the effect of the geometrical structure of the electric fieldon the corrosion of aluminum cathodes by electrolysis of aqueous solutions of sodium chloride. A correlation between the mass of the aluminum dissolved from the cathode and the factors electric current density, distance between the electrodes, electrolysis ...

The Townsend coefficient in non-uniform electric fields
Journal of Physics D: Applied Physics, 1991A one-dimensional model of electron multiplication in a gas is considered by using a system of equations of moments. An approximate expression for the first Townsend ionization coefficient is derived. It is shown that for a linearly decreasing electric field, the multiplication cannot be characterized by a local transport coefficient, such as Townsend ...

Electron Heating by Non-Uniform Electric Field
1974Current-voltage characteristics of asymmetrically necked samples cut from uniform single crystal of germanium become asymmetric at high electric fields. Current instabilities due to impact ionization are observed. A dc electromotive force arises in such samples in a large microwave field.

The transport parameters of electrons in a non-uniform electric field
Plasma Sources Science and Technology, 2007The object of this work is to calculate the transport parameters of electrons in a non-uniform electric field. Knowledge of the transport parameters is necessary for any modeling in plasmas and the determination of certain properties in plasmas. The method used in our calculation is the Monte Carlo method; it takes account of several random phenomena ...

Flute instability in the presence of non-uniform electric fields
Plasma Physics, 1967A general equation describing the flute instability in a low-β plasma, in the presence of a non-uniform electric field perpendicular to the magnetic field, is derived from guiding centre equations. The equations obtained by Rosenbluth and Simon and by Damm et al. correspond to two different limiting cases of this more general equation.
