Determining the electric-field strength in a passive film via photo-induced electric fields
Corrosion Science, 2019Abstract The nature of the electric-field strength in the passive film on tungsten is explored using photo-electrochemical techniques. A theoretical expression for the photo-stimulated growth of the film has been derived. Rotating ring-disk electrode (RRDE) experiments indicate that photo-corrosion of a tungsten electrode is negligible under super ...

Ice nucleation in high alternating electric fields: Effect of electric field strength and frequency
Physical Review E, 2021Icing is a severe problem for many technical systems such as aircraft or systems for high-voltage power transmission and distribution. Ice nucleation in water droplets is affected by several influencing factors like impurities or the liquid temperature, which have been widely investigated.

Maximum strength of the atmospheric electric field
Physical Review D, 2021Particle detectors of the European Space Environment Viewing and Analysis Network (SEVAN) network located on mountain peaks in Aragats (Armenia), Lomnicky Stit (Slovakia), and Musala (Bulgaria) are well suited for the detection of thunderstorm ground enhancements (TGEs).

Transportable Electric Field Strength Standard
Measurement Techniques, 2004Results from a study of a transportable electric field strength standard are presented. A measurement formula for the standard in the form of a product of three functions, an amplitude function, a frequency function, and a correction function, is obtained.

Critical Electric Field Strengths of Onion Tissues Treated by Pulsed Electric Fields
Journal of Food Science, 2010Abstract: The impact of pulsed electric fields (PEF) on cellular integrity and texture of Ranchero and Sabroso onions ( Allium cepa L.) was investigated. Electrical properties, ion leakage rate, texture, and amount of enzymatically formed pyruvate were measured before and

Electric Field Strength Due to Electric Excitation
2000We start with the modified Maxwell equations without electric and magnetic charges, having constant scalars for the permeability µ and the permittivity ϵ. The following equations apply to a medium at rest: $$curlH = \in \frac{{\partial E}}{{\partial t}} + {{g}_{e}}$$ (1) $$- curlE = \mu \frac{{\partial H}}{{\partial t}} + {{g}_{m ...

Optical measurements of electric field strength in nonuniform fields
[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002Describes optical measurements of the field-strength map in a liquid dielectric using the Kerr effect. Since electric lines of force are curved in a nonuniform field, the field strength can be measured on a plane which divides the center axis of two sphere electrodes into two equal parts and is perpendicular to the axis. On this plane, all of the field

Electric field strengths created by electrosurgical units
Proceedings of IEEE Symposium on Electromagnetic Compatibility, 2002The electromagnetic environment found in hospital operating rooms can be quite hostile to electronic medical devices. The electromagnetic fields existing in the operating rooms are created by both distant sources such as AM and FM broadcast towers as well as local sources such as electrosurgical units.

Increasing electric field strength in polymer capacitors
Nanobiosystems: Processing, Characterization, and Applications X, 2017Increased electric field breakdown in several polymer-based capacitor dielectrics, including biaxially oriented polypropylene, has been demonstrated using electron and hole blocking layers. Increased electric field breakdown translates into increased energy density.

Controlling flow direction in nanochannels by electric field strength
Physical Review E, 2015Molecular dynamics simulations are conducted to study the flow behavior of CsF solutions in nanochannels under external electric fields E. It is found that the channel surface energy greatly affects the flow behavior. In channels of high surface energy, water molecules, on average, move in the same direction as that of the electric field regardless of ...
