Science of The Total Environment, 2019
A series of electro-dewatering experiments were conducted to explore the effect of sediment cake thickness (1-5 cm) and electric field strength (2-50 V cm-1). The final dry solids content, energy consumption and dewatering productivity were modeled and the validity of the model was tested. It was demonstrated that the electric field strength determines

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.

Reference Standard of Low-Frequency Electric Field Strength With Electrical Traceability
IEEE Transactions on Instrumentation and Measurement, 2023For calibration of the environmental monitoring field meters, a reference standard of electric field strength based on parallel plates is established in the Primary electromagnetic laboratory FER-PEL in Croatia. The plate system incorporates guard ring electrodes with a set potential distribution to improve field uniformity within the center ...

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

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.

Killing of bacteria with electric pulses of high field strength
Radiation and Environmental Biophysics, 1981Bacteria of the type E. coli K12 have been treated in experiments using high-voltage pulses of short time (microseconds) as a killing agent. The role of different experimental parameters has been studied: kind of electrolyte, concentration, length of pulses, field strength, pH and temperature. Electrolytes with bivalent cations were found to reduce the

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 ...
