Concentrated high intensity electric field (CHIEF) is non-thermal pasteurization technology that uses microsecond pulses of electricity to inactivate bacteria without causing undesirable changes in flavor or quality of a product. This technology was explored as an alternative to current milk pasteurization processes, and was examined for its effects on microbial stability, sensory, quality and ...

This paper introduces an EMC-oriented study of the frequency-domain behavior of the electric field generated by two dipole antennas. First of all, the theoretical expression of this field is analyzed and confronted with the macromodel commonly used in electrical circuits. Then, the most significant components of the expression are included into the topological study of a two-dipole network thro...

We design a high dynamic range electric field sensor based on domain inverted electro-optic (E-O) polymer Y-fed directional coupler for electromagnetic wave detection. This electrode-less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. Experimental results demonstrate effective detection of electric field from 16.7V/m to 7...

Electric field calculations are not common practice in the design and development of non-ceramic insulators for high voltage transmission applications. This paper applies a three-dimensional (3D) electric field analysis program to calculate the field distribution at the live-end of 275kV and 330 kV non-ceramic insulators used in the Queensland transmission system. At these voltages, fields can ...

An extreme electric field on the order of 10(10) V m(-1) was applied to the free surface of an ionic liquid to cause electric-field-induced evaporation of molecular ions from the liquid. The point of ion emission was observed in situ using a TEM. The resulting electrospray emission process was observed to create nanoscale high-aspect-ratio dendritic features that were aligned with the direction...

We present a new touch-free technique for trapping, positioning and selecting human spermatozoa. This can be done in free solution (culture medium) by high-frequency electric fields. Ultramicroelectrodes fabricated by photo- and electron-beam lithography on quartz and glass substrates were used to create field cages or long field channels. If the conductivity of the external salt solution is hi...

In This paper describes the design and implementation of Microcontroller based High Voltage pulse electric field generator for Liquid food pasteurization. It generates a high voltage (15 kV) approximately in the frequency range from 250 Hz to 30 kHz. This high voltage applied for food pasteurization, which is placed between two electrodes.

We report a method for rapid, electric field directed assembly of high-density protein-conjugated microbead arrays. Photolithography is used to fabricate an array of micron to sub-micron-scale wells in an epoxy-based photoresist on a silicon wafer coated with a thin gold film, which serves as the primary electrode. A thin gasket is used to form a microfluidic chamber between the wafer and a gla...

The influence of an external electric field on the current in charged systems is investigated. The results beyond linear response from the classical hierarchy of density matrices are compared with the results from quantum kinetic theory. It is found that even an infinitesimal friction with the background changes the results in a noncontinuous way. The kinetic theory yields a systematic treatmen...
