Volume and Surface Resistivity Measurement of Insulating Materials Using Guard-Ring Terminal Electrodes

Energies, 2020
Recently, eco-friendly energy conversion policies have been being promoted through de-nuclearization and de-coal. For this purpose, a super grid should be built to optimize sustainable renewable energy resources such as solar and wind power. Accordingly,

Whole martensitic transformation process in Fe–Mn–Si–Cr shape memory alloy by improved characterization of volume resistivity

Journal of Materials Research and Technology, 2023
Since Fe–Mn–Si–Cr shape memory alloy (Fe-SMA) has been discovered, an improvement of the shape memory effect (SME) is challenged. Numerous attempts have been made thus far to improve SME.

A numerical approach to accurately estimate water resistivity (Rw) and saturation (Sw) in shaly sand formations

Contributions to Geophysics and Geodesy, 2022
In hydrocarbon reservoirs, the accuracy of hydrocarbon saturation depends on the precision of the water saturation and resistivity (Sw and Rw). A significant interpretation parameter is the resistivity of formation water (interstitial water or connate ...

Study on the thermal properties and insulation resistance of epoxy resin modified by hexagonal boron nitride

e-Polymers, 2021
To study the effect of doping hexagonal boron nitride (h-BN) on the thermal properties and insulation resistance of epoxy resin (EP) and the mechanism of this effect, h-BN/epoxy composites with h-BN content of 0, 10, 20, 30, and 40 phr were prepared ...
