Dependence of Ionic Mobility on Dielectric Constant of SolventBerns, D SFuoss, R M
Dielectric Constant The role of dielectric constantε of a solvent regarding its capability to dissolve ionized solutes was pointed out in Section 4.1 (the dielectric constant is typically given as the relative dielectric constant to vacuum). A higher dielectric constant of the solvent correlates with...
9•12 If the 8 dipole moment in the backbone chain is the source of the large P2, static polarization P2° is found to be almost constant in the range of temperature examined, which implies a rigid helix. Since P/ is proportional to M2, the value D298L in eq 2 appears to be ...
The results showed that the relativedielectric constantof pork was decreased with increasing frequency, and the dielectric loss factor reached a minimum at 2500MHz. The relation between thedielectric constantof the solvent and the dissociation constant of Glycine was... ...
Sets the value for the dielectric constant of the solvent. This option overrides Solvent if both ...
The dielectric constant of water in presence of increasing concentrations of weakly protic solvents depressing the freezing point has been measured. The same measurements have been carried out for various volume ratios between 20°C and the freezing point, as well as in presence of glycine. The co...
and high actuation strain. The DPG materials are often composed of solid and liquid phases which are made by polymer network and high dielectric constant of solvent (or plasticizer). Accordingly, the electromechanical coupling mechanisms of DPGs are more complex and are different with other electroni...
For C n H 2n+1 OH alcohols, n ≥4, most of the initially added water forms complexes: consequently, addition of water to these alcohols lowers the dielectric constant. 展开 关键词: Dielectric constants of water inn-alkanol solutions water-alcohol interaction Kirkwood correlation factor hydrogen-...
10. The composite dielectric substrate of claim 1, wherein the substrate maintains its dielectric constant in a high-frequency region of at least 100 MHz. 11. A prepreg prepared by dispersing a polyvinylbenzyl ether compound and a magnetic powder in a solvent to form a slurry, applying the ...
Calculations are carried out to determine the relation between the dielectric constant of solutions of large charged particles and the charge distribution on the particles. It is shown that if the hydrodynamic forces cause the particles to rotate about a point fixed in each particle, the dielectric...
