Electric field measurement in electric-field modified flames

open access: yesProceedings of the Combustion Institute, 2021
Abstract The application of an electric field to a flame modifies the flame characteristics due to the collective motion of charged particles generated within the flame. The applied field mobilises electrons and ions depending on their polarity, leading to localised regions of space charge with sufficient density to either locally amplify or shield ...

Static electric field detection and behavioural avoidance in cockroaches [PDF]

open access: yes, 2008
Electric fields are pervasively present in the environment and occur both as a result of man-made activities and through natural occurrence. We have analysed the behaviour of cockroaches to static electric fields and determined the physiological ...

Tripolar electric field Structure in guide field magnetic reconnection [PDF]

open access: yesAnnales Geophysicae, 2018
It has been shown that the guide field substantially modifies the structure of the reconnection layer. For instance, the Hall magnetic and electric fields are distorted in guide field reconnection compared to reconnection without guide fields (i.e ...
