Interfacial Polarization and Electrical Conductivity in Sapphire
Journal of the American Ceramic Society, 1965Dielectric relaxation effects, a dissipation factor peak, and both capacitance and conductivity dispersions were observed in pure and doped single crystals of Al 2 O 3 between 10 2 and 10 5

Polar Interfacial Interactions in RPLC
Israel Journal of Chemistry, 1990AbstractThe three principal forces that govern the interaction between dissolved proteins and solid (flat or particulate) surfaces immersed in a polar liquid are:A. Lifshitz‐van der Waals forces (LW interactions)B. Polar (hydrogen bond, or Lewis acid‐base) forces (AB interactions, which include “hydrophobic” interactions)C.

Interfacial behavior of polar, weakly polar, and nonpolar compounds bound to activated carbons
Journal of Colloid and Interface Science, 2013Detailed 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 ...

Interfacial polarization in statistical mixtures
Journal of Surface Investigation. X-ray, Synchrotron and Neutron Techniques, 2010The results of experiments on the interfacial polarization intrinsic to a dielectric-semiconductor statistical mixture are discussed. A new qualitative model applicable for description of interfacial polarization in macrosystems is proposed.

Electrode and interfacial polarization in broadband dielectric spectroscopy measurements
Review of Scientific Instruments, 2001The 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 ...

Polarization Structure of Interfacial Amorphous Films
Nature, 1969ONE of us1–4 has already established that amorphous surface layers have a persistent character which can manifest itself in the oriented crystallization of material on top of them. The part played by these amorphous interfacial films in the transmission of structural information is not understood: it is not known whether they act merely as an inert ...

Fluorescent probes used to monitor membrane interfacial polarity
Chemistry and Physics of Lipids, 1999The polarity of the interface between a lipid bilayer membrane and bulk water is an important physical parameter of the membrane. It is likely that several membrane-dependent biological functions are modulated by this property. However, interfacial polarity can be difficult to define because of an imprecise knowledge of the molecular nature of the ...

Nonlinear phenomenon of interfacial polarization immittance of a Pt electrode
Annals of Biomedical Engineering, 1990Description of a computerized, automated method to measure the interfacial polarization immittance of a Pt electrode in nonlinear range is presented. The classical three-electrode setup is used for measurements in conjunction with a special purpose software implemented on a Unix computer using C language.

Halo polarization profiles and the interfacial angles of ice crystals
Applied Optics, 1994Polarization and radiance of various types of refraction halo in ice-crystal swarms that extend to ground level were measured as a function of scattering angle. Simultaneously, samples of the crystals that produce these halos were collected and replicated.

Interfacial Properties of Polar Liquids Against Nonpolar Phases
Journal of Pharmaceutical Sciences, 1974The interfacial tension of 10 polar liquids against hexane and tetradecane and the contact angle against paraffin, polyethylene, and polytetrafluoroethylene were measured. Work-of-adhesion values against any one nonpolar phase, calculated from these data, are independent of the polar liquid used.
