deposition, post-processing and surface modification for better mechanical and environmental resistance, controlled wettability and electric conductivity
Copper-coated fibers are known for better EMI shielding and electric conductivity
at higher temperatures.
Attributing to its physical properties such as excellent electric conductivity
, creep resistant, heat stabilizing and light weight, yttrium is garnering tremendous attention from industrial and manufacturing sectors.
These phenomena are characteristic of polar polymers, as expected, the dielectric permittivity of the nanocomposites increases with the filler content up to 50 wt% at the measured frequency range due to gradually enhanced interfacial polarizations because of the large electric conductivity
discrepancy between the filler and the matrix.
In the brain, it's electric conductivity
that allows me to think and talk at the same time."
The electric conductivity
were measured using a two-point method with a Keithley 6517A programmable electrometer, which at the same time served as a source of the DC voltage.
(1) With PVA, when 8 ml (52.7 [micro]s/cm) or 10 ml (59.5 [micro]s/cm) of DW (200 ml) is added, the electric conductivity
has no significant change, meaning that it has reached saturation.
The typical termination criteria usually used during the test were (1) a steady hydraulic conductivity value for at least 4 consecutive measurements, (2) the hydraulic conductivity test should be performed for more than 24 h, (3) the ratio of pH, electric conductivity
(EC), and the Pb concentrations between the effluents and influents are within 1.0 [+ or -] 0.1 [25-27].
The details of the topics in this special issue include the following: (1) effect of polar groups on the dielectric properties of dielectric polymers; (2) review of designing and preparing of high dielectric constant polymeric composites; (3) electric conductivity
of polymeric composites with copper as a filler; (4) AC conductivity of polymeric composites with a conductive polymer as an additive; (5) designing of copolymers with optimized photoelectric properties through theoretical calculations; (6) microwave absorption properties of polyaniline and magnetite core-shell structured hybrid; and (7) polyimides as binder polymers on organic light-emitting diode panels.
where [sigma] and V are tissue electric conductivity
(S/m) and electric potential (V), respectively.
However, there are many factors that can influence the determination of the electric conductivity
including soil density, porosity, particle shape and orientation, cation composition, and temperature.
To reach their findings, the researchers used several methods such as nuclear magnetic resonance (NMR), spectroscopy and infrared spectroscopy, dynamic light scattering, conductometry to measure the solutions' electric conductivity
, and viscometry to measure fluid viscosity.
