Cavitation in dielectric fluid in inhomogeneous pulsed electric field

Pulsed Electric Field Processing in Food Technology

Pulsed electric field (PEF) processing is a emerging method of food preservation that uses short bursts of electricity for microbial inactivation (cell-lysis) and causes minimal or no detrimental effect on food quality attributes. PEF can be used for processing liquid and semiliquid food products.

Electric-field fluctuations in random dielectric composites

When a composite is subjected to a constant applied electric, thermal, or stress field, the associated local fields exhibit strong spatial fluctuations. In this paper, we evaluate the distribution of the local electric field ~i.e., all moments of the field! for continuum ~off-lattice! models of random dielectric composites. The local electric field in the composite is calculated by solving the ...

Pulsed light and pulsed electric field for foods and eggs.

Two new technologies for use in the food industry are described. The first method discussed uses intense pulse of light. This pulsed light (PureBright) process uses short duration flashes of broad spectrum "white" light to kill all exposed microorganisms, including vegetative bacteria, microbial and fungal spores, viruses, and protozoan oocysts. Each pulse, or flash, of light lasts only a few h...

Mean field theory of inhomogeneous fluid mixtures

Electric-field dependence of the effective dielectric constant in graphene.

The dielectric constant of a material is one of the fundamental features used to characterize its electrostatic properties such as capacitance, charge screening, and energy storage capability. Graphene is a material with unique behavior due to its gapless electronic structure and linear dispersion near the Fermi level, which can lead to a tunable band gap in bilayer and trilayer graphene, a sup...
