Abstract:

The results of measurements of the thickness of a non-conductive coating on an electrically conductive non-magnetic base metal using the existing amplitude technique of eddy current non-destructive testing are strongly influenced by the specific electrical conductivity of the base metal. To eliminate this problem, it is proposed to use an eddy current probe with amplitude-phase signal processing. Its graduation is carried out using several base metals with different specific electrical conductivity using a coating thickness simulator, the number of graduation points is comparable to the resolu

Abstract:

Systems generating strong magnetic fields are widely used in modern fundamental and applied research as well as in the most innovative industrial processes. These devices generate magnetic fields that reach 5–100 T and the conductors are subjected to a huge Lorentz force, so the conductor material must be extremely strong (UTS ≥ 700 MPa) and have a good specific electrical conductivity (IACS ≥ 60%). Since traditional conductors such as copper, aluminum, gold, and silver cannot withstand such loads, microcomposite materials have been developed that are characterized by such high strength and go

Abstract:

The temperature dependencies of physical and chemical properties (viscosity, density, electrical conductivity) and the melting temperature of 1M solutions of lithium salts (LiClO4 and LiBF4) in the mixture of sulfolane and sulfurous anhydride (∼1M) were studied. It was shown that the introduction of 1M (5% wt.) of sulfurous anhydride into 1M solutions of LiClO4 and LiBF4 in sulfolane increased the specific and corrected electrical conductivity, densities, activation energy of electrical conductivity and viscous flow of electrolyte solutions; and reduced viscosity and melting temperatures.

Abstract:

Carbonaceous materials used in most electrochemical applications require high specific surface area, adequate pore size distribution, and high electrical conductivity to ensure good interaction with the electrolyte and fast electron transport. The development of transition metal doped graphene aerogels is a possible solution, since their structure, morphology, and electrical properties can be controlled during the synthesis process. This work aims to synthesize Ni-doped graphene aerogels to study the role of different nickel salts in the sol-gel reaction and their final properties. The charact

Abstract:

Aluminum in terms of electrical conductivity among all known metals ranks fourth after silver, copper and gold. The electrical conductivity of annealed aluminum is approximately 62% IACS of the electrical conductivity of annealed standard copper, which at 20 °C. is taken as 100% IACS. However, due to its low specific gravity, aluminum has a conductivity per unit mass 2 times greater than copper. This property of aluminum gives us an idea of the economic viability of using it as a material for conductors. With equal conductivity (the same length), the aluminum conductor has a cross-sectional ar
