The Dielectric Constant of Water and the Saturation Effect The Onsager and Kirkwood theories of polar dielectrics are extended to give expressions for the dielectric constant at high field strengths. The theory is ... F. J. Booth - 《Journal of Chemical Physics》 被引量: 572发表: 1951年 THE...

strength of van der Waals andelectrostatic forces. Moreover, the role of water molecules inhydrophobic interactionsandhydrogen bondformation are among other factors that need to be considered in protein adsorption, which is supported by a study showing that the structure of the water molecules ...
For theE||apolarization, we find a broad relaxation-like excitation whose peak frequency decreases when the temperature is lowered down toT0 ≈ 3 K and increases on further cooling. Around the same temperature, pronounced anomalies are observed in the dielectric strength of the excitation an...
The frequency and temperature dependence of dielectric properties and the breakdown field are mainly dependent on the polymer matrix. Many polymers have been selected as a matrix according to their glass transition temperature, melting temperature, flexibility, dielectric strength, and processability, ...
Dielectric strength is the maximum electric field a dielectric material can withstand without breaking down. It is measured in volts per meter (V/m) or kilovolts per millimeter (kV/mm). Breakdown occurs when the field exceeds the binding force of electrons, causing them to escape and create a...
NaCl accelerates the reorientation motion of surface-bound water, which implies an increase of the rotational degree of freedom. However, for water beyond the hydration layer, retarded collective reorientation motion and increased dielectric strength are observed, suggesting NaCl enhances intermolecular ...
Generally, the dielectric constant of air is defined as 1 and other dielectric constants are determined with reference to it. Other properties of interest in a dielectric are dielectric strength, a measure of the maximum voltage it can sustain without significant conduction, and the degree to ...
The dielectric property of the insulating materials can be evaluated by measuring dielectric strength (Ds), dielectric constant (k), and the dissipation factor or loss tangent (tan δ). The dielectric strength of the ceramics can be defined as the maximum level of electric field strength that it...
The alternating current (AC) breakdown strength (BDS) of an insulation system can be as high as the dielectric strength of the weakest link in the system. One of the most critical failure mechanisms within the insulation system is the electrical breakdown of the interface between two solid ...
