Flux quantumFine structureconstantSpintronicsRatio of electron charge radius and Compton wavelength of electron is known to be equal to the dimensionless electromagnetic coupling constant e2/c. It is pointed out that the coupling constant has two alternative interpretations: as a ratio of two angular ...
The net electric flux through a closed surface is infinite only if the net charge enclosed by the surface is zero infinite only if there are no charges enclosed by the surface zero if the net charge enclosed by the surface is zero

Next-generation neutrino telescopes with substantially improved sensitivity are required to pinpoint the sources of the diffuse astrophysical neutrino flux detected by IceCube and uncover the century-old puzzle of cosmic-ray origins. A detector near the
Field-assisted self-assembly, motion, and manipulation of droplets have gained much attention in the past decades. We exhibit an electric field manipulation of the motion of a liquid metal (mercury) droplet submerged in a conductive liquid medium (a solu
It states the difference of electric potential between two points of an electrolyte solution, which is moving with alternating acceleration. The mechanism of such potential appearing was considered as a shift of the opposite charges existing in a plasma-like electrolyte, analogously to shift, which ...
