Fluctuation-enhanced electric conductivity in electrolyte solutions. [PDF]

Proc Natl Acad Sci U S A, 2017
In this letter we analyze the effects of an externally applied electric field on thermal fluctuations for a fluid containing charged species. We show in particular that the fluctuating Poisson-Nernst-Planck equations for charged multispecies diffusion ...

Electric Conductivity Probes to Study Change in Degree of Saturation - Bench Top Laboratory Tests [PDF]

E3S Web of Conferences, 2020
Sand characteristics such as liquefaction susceptibility can be affected as a result of change in degree of saturation of sand. New liquefaction mitigation technique by inducing partial saturation in sands is introduced by Yegian et al in 2007[1].

Direct photons emission rate and electric conductivity in twice anisotropic QGP holographic model with first-order phase transition

European Physical Journal C: Particles and Fields, 2022
The electric conductivity and direct photons emission rate are considered in the holographic theory with two types of anisotropy. The electric conductivity is derived in two different ways, and their equivalence for the twice anisotropic theory is shown.
