Analytic approach to the interfacial polarization of heterogeneous systems

Physical Review B, 1993
We have obtained an analytical solution of Maxwell's equations for a dielectric system of spherical particles in a medium. The system is placed between two parallel electrode plates, subject to a low-frequency alternating potential, and the solution is obtained from the corresponding boundary-value problem for the Green function.

Electrode and interfacial polarization in broadband dielectric spectroscopy measurements

Review of Scientific Instruments, 2001
The accumulation of charge carriers at the sample-electrode interface in broadband dielectric spectroscopy results in large electrode polarization masking the frequency response of the sample. Additionally, heterogeneous samples exhibit frequency-dependent dielectric and conductive properties that differ from those of the constituent components ...

Bulk and interfacial properties of polar and molecular fluids

Physical Review A, 1992
Based on a suitable density-functional theory for inhomogeneous fluids we investigate both the liquid-vapor coexistence curve of the bulk phase diagram and interfacial structures of molecular fluids in general and Stockmayer fluids in particular. We derive a scheme which allows us to analyze one-component fluids composed of molecules with strong ...

Interfacial behavior of polar, weakly polar, and nonpolar compounds bound to activated carbons

Journal of Colloid and Interface Science, 2013
Detailed analysis of the interfacial behavior of water and weakly polar or nonpolar organics adsorbed alone or co-adsorbed onto activated carbons (AC) at different temperatures is a complex problem important for practical applications of adsorbents. Interaction of water, 1-decanol, and n-decane with AC possessing highly developed porosity (pore volume ...

Asymmetric Bond Delta‐Polarization at the Interfacial Se─Ru─O Bridge for Efficient pH‐Robust Water Electrolysis

Advanced Functional Materials
The rationalization of pH‐robust catalysis is highly desired but challengeable for overall water electrolysis (WE). It requests a metal active site that can make an efficient adaption with both cathodic hydrogen and anodic oxygen evolution reactions (HER/

Electron Migratory Polarization of Interfacial Electric Fields Facilitates Efficient Microwave Absorption

Advanced Functional Materials
High‐performance microwave absorption materials (MAM) are often accompanied by synergistic effects of multiple loss mechanisms, but the contribution share of various loss mechanisms has been neglected to provide a template and reference for the design of

Interfacial polarization in silicone oil-polypropylene insulating system

Journal of Electrostatics, 1982
Abstract Silicone oils, PP films and their composed insulating systems polarized by high DC fields at high temperatures showed several TSC peaks in the temperature range from −140 to 150°C and their origins were clarified. The oil-PP insulating systems exhibited two remarkable TSC peaks due to interfacial polarizations at the oil-PP interfaces. These

Possible interfacial polarization between two monatomic condensed bodies

Chemical Physics Letters, 1976
Abstract It is shown that in a system consisting of two different monatomic bodies separated by a plane interface, a possibly measurable permanent contact polarization may appear due to the correlation of the electronic motions from one body to another. The order of magnitude of this effect is discussed.

Dielectric Properties of NiO–Interfacial Polarization Effect–

Journal of the Physical Society of Japan, 1969
Dielectric constant of single crystals of NiO, both pure and containing small amounts of Li, has been measured in the frequency range from 10 2 to 2.4×10 10 Hz as a function of temperature between 150 and 450°K. At low temperatures the dielectric constant has a constant value independent of temperature, while at high temperatures it increases strongly ...
