Electrical Conduction in Dilute Amalgams

Electrical Conduction in Dilute Amalgams.

The modem theory of electrical conduction in metals, according to which the metal is dissociated to give a positive ion of low mobility, which is characteristic of the metal, and a negative carrier of high mobility, which is common to all metals and presumably to be identified with the electron, has given rise to certain misgivings, despite the complete analogy between this theory and the accep...

Electrical Conduction in Nonlinear Composites

Composite systems constitute a large class of naturally occurring or artificially synthesized disordered systems [1]. The systems are microscopically inhomogeneous and disordered but look homogeneous on the macroscopic scale. From the tunnelling electron micrographs (TEM) of such a composite material it can be seen that the typical dimension (ξ) of metallic islands embedded in the insulating ma...

Basic Elements of Electrical Conduction

Impact on Cardiac Electrical Conduction

Gap junction channels, required for the propagation of cardiac impulse, are intercellular structures composed of connexins (Cx). Cx43, Cx40, and Cx45 are synthesized in the cardiomyocytes, and each of them has a unique cardiac expression pattern. Cx40 knock-in Cx45 mice were generated to explore the ability of Cx45 to replace Cx40, and to assess the functional equivalence of these two Cxs that ...

Electrical Conduction in the Early Universe

The electrical conductivity has been calculated 1 in the early universe at temperatures below as well as above the electroweak vacuum scale, Tc ≃ 100GeV. Debye and dynamical screening of electric and magnetic interactions leads to a finite conductivity, σel ∼ T/α ln(1/α), at temperatures well below Tc. At temperatures above, W charge-exchange processes – analogous to color exchange through gluo...
