The concept of pulsed electric fields (PEF) was first proposed in 1967 to change the behavior or microorganisms. The electric field phenomenon was identified as membrane rupture theory in the 1980s. Increasing the membrane permeability led to the application of PEF assisted extraction of cellular content and transfer of genetic material across cell ...

Rhabdomyolysis Due to Pulsed Electric Fields
Plastic and Reconstructive Surgery, 1990High-voltage electrical trauma frequently results in extensive and scattered destruction of skeletal muscle along the current path. The damage is commonly believed to be mediated by heating. Recent experimental and theoretical evidence suggests, however, that the rhabdomyolysis and secondary myoglobin release that occur also can result from ...

Pulsed Electric Field Processing
2019Despite comprehensive studies that have reported on the impact of pulsed electric fields (PEF) on the safety, nutrition, sensory, and physicochemical properties of vegetables, juices, and red meat, little research has been reported to address the effect of PEF on aquatic resources such as fish and shellfish.

Electric Field Pulses Can Induce Apoptosis
The Journal of Membrane Biology, 1999Injection of electric field pulses of high intensity (kV/cm) and short duration (microsecond range) into a cell suspension results in a temporary increase of the membrane permeability due to a reversible electric breakdown of the cell membrane. Here we demonstrate that application of supercritical field pulses between 4. 5 and 8.1 kV/cm strength and 40

Electromembrane process with pulsed electric field
Desalination, 2006Electromembrane process yields can be enhanced by using pulsed electric field. Electrodialysis experiments carried out on brackish water solutions show that the same level of desalination can be reached faster under pulsed field conditions. A model based on the Nernst–Planck equations is developed to explain this behavior.

Pulsed high electric field sterilization
7th Pulsed Power Conference, 2005High electric fields (> 2kV/cm) are known to kill microorganisms by causing dielectric breakdown of their cell membrane. This effect can in principle be used in food preservation and waste water treatment. The field strength required to maximize the kill for a given energy is shown here to be higher than the maximum field strength of 25 kV/cm used in ...

Applications of Pulsed Electric Fields in Winemaking
2022Wineries may take advantage of the ability of PEF to electroporate cell membrane of grape skins and microbial cells to improve different operations. PEF permeabilization of red grape skin cells permits reducing the duration of the maceration or to increase the color and concentration of anthocyanins and polyphenolic compounds in the wine without ...

Pulsed Electric Field Processing
2001Doevenspeck’s patent, dating to the 1960s, describes a variety of pulsed electrical field (PEF) equipment and methods ranging from PEF processing of sausage to specific electronic embodiments. PEF development diverged into two different, though related, areas of endeavor: reversible electroporation, or PEF performed under conditions promoting ...

Nonuniform electric fields in pulse heated wires
International Journal of Thermophysics, 1993The influence of nonuniform electric fields on the measurement of the electrical conductivity in pulse-heated wires is studied analytically. Two causes for nonuniformity are considered: switching-on of an external voltage source (transient skin effect) and temperature-dependent change of the electrical conductivity.

Pulsed electric field assisted assembly of polyaniline
Nanotechnology, 2012Assembling conducting polyaniline (PANi) on pre-patterned nano-structures by a high rate, commercially viable route offers an opportunity for manufacturing devices with nanoscale features. In this work we report for the first time the use of pulsed electric field to assist electrophoresis for the assembly of conducting polyaniline on gold nanowire ...
