Various researches are employed to analyze the role of various indifferent electrolytes on the concentration polarization, potential distributions and the monolayer charge of the process of Langmuir monolayer deposition onto a substrate surface. The results show that the indifference electrolytes lead to an increase in the deposition rate, which further increases the monolayer ionization and charge that is not normally observed otherwise.

Instability due to surfactant redistribution in a liquid membrane system consisting of two solutions separated by a layer of immiscible liquid was theoretically studied. A mechanism of oscillation, which develops at the membrane/acceptor phase interface, was proposed on the basis of direct numerical simulation of the system evolution.

The thermodynamic characteristics of the cluster formation for fatty acids with the general formula of nondissociated n-carboxylic acids C(sub n)H(sub 2n+1)COOH with n = 5-15 are studied. The contributions of the CH2 groups to the thermodynamic characteristics of alcohols and acids are the same and the differences in the formation of clusters by these substances are attributed to the differences in the structure and interactions of relevant functional groups.

A study for addressing the electric field and ionic concentration distributions developing around the three-phase contact line during the Langmuir-Blodgett deposition of charged monolayers is conducted. The results reveal that, for sufficiently high deposition rates, the subphase composition substantially changes in the immediate locality of the three-phase contact line.

The study calculated the framework of PM3 molecular orbital approximation the thermodynamic function characteristics of the formation and geometrical structure of monomers, dimers, trimers, and tetramers of fluoroalkanols. It concluded that fluoroalkanol monomers posses a helical structure with an average backbone torsion angle equal to 162 degree, which implies optical activity of these molecules and the existence of two types of dimers, dimers with equal and opposite directions of helixes winding.

A study was conducted on the effect of high NaCl concentrations in the aqueous subphase on the structure and phase properties of selected n-hydroxystearic acid monolayers. The main characteristic features of 2-, 9-, 11-, and 12- hydroxystearic acid monolayers spread on 1 M NaCl aqueous pH 3 subphase were determined by studying the phase behavior, morphological texture, and lattice structure.

The mechanism of the meniscus oscillations and the stripes formation within the deposited fatty acid monolayer is theoretically analyzed on the basis of a supposition of concentration polarization within the solution during the deposition process. The results reveal that the proposed mechanism corresponds to the observed meniscus behavior during oscillations and agrees with numerous experimental data on adhesion work, contact angles, and maximum monolayer deposition rate.

The chiral discrimination energies in domains composed of chiral amphiphilic monolayers are theoretically studied. However, systematic coarse-graining of model systems shows that the consistent use of a set of parameters can correctly predict the chiral preference. The model calculation suggests that, with a gradual loss of chirality of the model molecule, the chiral interaction is diminished.

An effective pair potential (EPP) theory was used to correlate the molecular chiral structure of a phospholipid dipalmitoylphosphatidylcholine (DPPC) and the handedness of the mesoscopic domain composed of DPPC. The distribution of the headgroup orientation in the aqueous subphase does not destroy the chirality of the domain shape.

The dynamics of a mixed monolayer consisting of a soluble tailored amphiphile N-decyl-gamma-hydroxybutyric acid amide and its insoluble condensing homologue N-tetradecyl-gamma-hydroxybutyric acid amide are experimentally and theoretically studied. The result reveals that the theoretical predictions are in satisfactory agreement with the experiments.
