ABSTRACT: Strong electrical forces have been revealed in electrically active heterogeneous finely dispersed systems at the interfaces
between the solid and liquid phases. It has been established that these forces give rise to gradients of the potential of
an internal self-electric field that can provide circulation of electric currents in the systems under investigation. It has
been found that, in these systems, there arises a double electric layer that represents a new structuring phase, which is
characteristic of electrically active systems only. The mechanism of formation of a double electric layer includes electrocontact
interaction between the surfaces of two heterogeneous liquid and solid polar dielectrics.

ABSTRACT: A theoretical model has been proposed which makes it possible to introduce the correction into the complex permittivity of
electrically active condensed systems that contain a polar liquid matrix and low-dimensional solid particles with a developed
electrically active surface. It has been established that there is an interfacial electrical interaction between surface charges
of the solid component and polar molecules of the liquid matrix. The processes occurring during this interaction lead to the
appearance of an intrinsic internal electric field in the system under investigation. The contribution from surface effects
to the formation of the polarized state of the polar liquid medium has been investigated in terms of the proposed model. The
possibility of controlling the processes of local change in the structure of the polar liquid component under the effect of
the internal electric field by varying the electrically active specific surface area of the solid phase and the intrinsic
dipole moment of molecules of the liquid matrix has been analyzed in the studied systems. The conditions providing for the
appearance of a controlled potential gradient of the internal electric field have been determined for the dispersed systems
under consideration. The parameter that makes it possible to evaluate the contribution from the interfacial electrical contact
interaction to the dielectric response of the liquid component and the entire system has been introduced for the first time.

ABSTRACT: The nature and mechanism of interfacial electrical interaction in organic colloids containing an active solid phase and a
polar liquid phase are studied. Such systems are shown to offer specific properties. Specifically, high electrical forces
producing gradients of the potential of the self-electric internal field arise at the liquid-solid interface. In the presence
of free charges and ionic conductivity channels, this field can induce currents in such systems. When investigating the colloid
system of the human venous blood, it is found that the internal field causes mesoscopic inhomogeneity in the structure of
the aqueous components of the plasma and cytoplasm. It is shown that the concentration of free water molecules in the liquid
phase of the system is maximal in group I blood and the physically nonuniform properties of combined water show up to the
greatest extent in group IV blood. This finding is corroborated by the dispersion of the dielectric polarization in blood
of different groups.

ABSTRACT: Experimental and theoretical investigations of the electret effect in low-dimensional micas with different degrees of dispersion
and adsorption are carried out at temperatures in the range 20–140°C. The results obtained allow the electric activity of
the mica particles comprised in these systems to be determined and the efficiency of application of low-dimensional micas
for fillers of composite materials to be estimated.

ABSTRACT: The electret properties and electrotransport of venous human blood of various groups and a disperse system based on fine-grained
mica are studied. General laws are revealed in the thermally stimulated current spectra of these inorganic and organic systems.
The nature of the current peaks and their relation to the physicochemical transformations and the interphase interactions
in these systems are discussed. A set of numerical parameters is obtained to describe the electrophysical state of the biological
system; it can be used to diagnose the functional and biochemical states of this system.

ABSTRACT: The electrical properties of water films in residual electric fields on the surface of crystals and in slitlike capillaries
of layered silicates are investigated. The results obtained indicate a substantial change in the water structure, degradation
of the dipole-orientation polarization of molecules, and a decrease in the crystallization temperature.
