Three-axis electrical induction sensor of electric field strength in form of three mutually perpendicular disks [PDF]

open access: yesОмский научный вестник, 2020
Measuring the parameters of electric fields affecting technical and biological objects is impossible without the use of electric field strength sensors. Accurate measurement and control of electric field strength levels is challenging.

Charge screening and carrier transport in AA-stacked bilayer graphene: tuning via a perpendicular electric field [PDF]

open access: yesSolid State Communications 202, (2015) 14-18, 2014
The static dielectric function in AA-stacked bilayer graphene (BLG), subjected to an electric field applied perpendicular to layers, is calculated analytically within the random phase approximation (RPA). This result is used to calculate the screened Coulomb interaction and the electrical conductivity.

Electric field–induced selective catalysis of single-molecule reaction

open access: yesScience Advances, 2019
A cascade chemical reaction is selectively activated through oriented external electric field at the single-molecule scale. Oriented external electric fields (OEEFs) offer a unique chance to tune catalytic selectivity by orienting the alignment of the ...

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 ...

Integrating electric field modeling and neuroimaging to explain inter-individual variability of tACS effects

open access: yesNature Communications, 2019
Transcranial electrical stimulation (tES) of the brain can have variable effects, plausibly driven by individual differences in neuroanatomy and resulting differences of the electric fields inside the brain.

Electric Field Determination in DC Polymeric Power Cable in the Presence of Space Charge [PDF]

open access: yes, 2007
The pulsed electroacoustic (PEA) technique was used to perform space charge measurements in polymeric power cables. However, for a practical dc power cable the electric field is affected by conductivity of the material, which is a function of both ...

Electron-positron pair oscillation in spatially inhomogeneous electric fields and radiation [PDF]

open access: yesPhys.Lett.B691:99-104,2010, 2010
It is known that strong electric fields produce electron and positron pairs from the vacuum, and due to the back-reaction these pairs oscillate back and forth coherently with the alternating electric fields in time. We study this phenomenon in spatially inhomogeneous and bound electric fields by integrating the equations of energymomentum and particle ...
