Decomposition of high-frequency electrical conductivity into extracellular and intracellular compartments based on two-compartment model using low-to-high multi-b diffusion MRI

open access: yesBioMedical Engineering OnLine, 2021
Background As an object’s electrical passive property, the electrical conductivity is proportional to the mobility and concentration of charged carriers that reflect the brain micro-structures.

Lorentz Force Electrical Impedance Tomography

open access: yes, 2013
This article describes a method called Lorentz Force Electrical Impedance Tomography. The electrical conductivity of biological tissues can be measured through their sonication in a magnetic field: the vibration of the tissues inside the field induces an

A transport coefficient: the electrical conductivity [PDF]

open access: yes, 2005
I describe the lattice determination of the electrical conductivity of the quark gluon plasma. Since this is the first extraction of a transport coefficient with a degree of control over errors, I next use this to make estimates of other transport ...

Light-activated modulation and coupling in integrated polymer-liquid crystal systems [PDF]

open access: yes, 2014
We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device.

Electrical characterizations of Al2O3/ITO grain boundary composites

open access: yesJournal of Asian Ceramic Societies, 2022
To retain the advantageous properties of Al2O3 ceramics, their electrical conductivity must be controlled using a small amount of the conducting phase by pressure-less sintering in an air atmosphere.
