Investigating membrane breakdown of neuronal cells exposed to nonuniform electric fields by finite-element modeling and experiments [PDF]

, 2002
High electric field strengths may induce high cell membrane potentials. At a certain breakdown level the membrane potential becomes constant due to the transition from an insulating state into a high conductivity and high permeability state.

Electric-Field Breakdown of Absolute Negative Conductivity and Supersonic Streams in Two-Dimensional Electron Systems with Zero Resistance/Conductance States [PDF]

, 2003
We calculate the current-voltage characteristic of a two-dimensional electron system (2DES) subjected to a magnetic field at strong electric fields. The interaction of electrons with piezoelectric acoustic phonons is considered as a major scattering ...

Breakdown property of ±320 kV HVDC cable system XLPE/EPDM accessories

电力工程技术, 2023
In high voltage direct current cable system, the cable joint and termination are the weakness to stand high voltage, thus making their breakdown strength the critical property to the reliability of power transmission system.

Indirectly Measured Ambient Electric Fields for Lightning Initiation in Fast Breakdown Regions

Geophysical Research Letters, 2020
We report a new approach to measure indirectly the ambient thunderstorm electric fields in fast positive breakdown regions. For a given geometry of the discharged fast breakdown region, we show that there is a minimum ambient electric field required to ...
