The anionic conductance across toad (Bufo viridis) skin was studied using the voltage-clamp technique following long-term (more than 10 days) acclimation to NaCl and KCl solutions. The non-specific baseline conductance was approximately 0.6 mS cm(-)(2) and was similar in skins from all acclimation conditions. The voltage-activated Cl(-) conductance (G(Cl)) was maximal in skins from distilled-wa...

In this paper, we investigate the electrical conductance and density of states of a nanocrystal including an electrical charge or dipole located at cross section of nanocrystal by using Green’s function method in the nearest neighbor tight-binding approach. The results show that moving the electrical charge from center to the edge of the nanocrystal increases the system transmission coefficient...

The deviation of specific electrical conductance (EC) from conservative mixing behavior is well-established in the scientific literature. This principle based on observation that, as salt concentration a water sample increases, mobility individual ions decreases, and thus their ability to conduct electricity decreases. Despite this fact, some commonly used models for salinity transport San Fran...

In this study, we derive analytically Green’s function (GF) formalism to calculate the electrical conductance for an armchair SWCNT in the ballistic regime. We obtain an exact analytical formula for the conductance of the SWCNT, in the tight-binding approach and assuming nearest-neighbor interaction by recursion process in the GF formalism. We show that in the presence of uniform external poten...

The most common method for in situ assessment of soil salinity, namely the electrical conductivity (EC) of the soil solution (ECw), is to measure the apparent electrical conductivity (ECa) and volumetric water content (θ) of the soil and apply measured or predicted ECa(ECw, θ) calibration curves. The water content and electrical conductivity of a soil solution are indeed the major factors affec...

In this paper, we study the electronic conductance of a nanoribbon with square lattice by using Green’s function theory within the tight-binding approach. For this purpose, we separate the conductance modes in the ideal parts by using a suitable unitary transformation in order to obtain the analytic formula for the corresponding self-energies. Then, we present a fast computer algorithm based on...
