Physical and chemical mechanisms that influence the electrical conductivity of lignin-derived biochar

open access: yesCarbon Trends, 2021
Lignin-derived biochar is a promising, sustainable alternative to petroleum-based carbon powders (e.g., carbon black) for polymer composite and energy storage applications. Prior studies of these biochars demonstrate that high electrical conductivity and

Electrical conductivity in hexaalkoxytriphenylenes [PDF]

open access: yesRecueil des Travaux Chimiques des Pays-Bas, 1987
AbstractTriphenylenes containing six side‐chains O(CH2)nCH3, n  3‐5, have been prepared and doped with iodine. The compounds show mesophases which have been characterised by differential‐scanning calorimetry and small‐angle X‐ray scattering. Samples doped with iodine show an electrical conductivity of 10−4‐10−3Ω−1·m−1, which is slightly higher in the ...

Clinical Usage of Tissue Electrical Conductivity during the Electroporation: An Essential and Useful Factor

open access: yesFrontiers in Biomedical Technologies, 2021
Electric field intensity at each point is responsible for pore creation in the cell membrane during the electroporation process. These pores can increase the tissue electrical conductivity in the electroporation.

Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle [PDF]

open access: yes, 1991
This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated.

Electrical Conductivity of Field-Structured Emulsions

open access: yesFluids, 2020
The structure formation influence on various macroscopic properties of fluid–fluid disperse systems is poorly investigated. The present work deals with the experimental study of the charge transfer in emulsions whose dispersed phase droplets are arranged
