Distribution of colloidal particles in a spherical cavity

Article Abstract:

The distribution of colloidal particles in a spherical cavity under the conditions of relatively large cavities, low cavity and colloidal particles potentials, and low monovalent electrolyte and colloidal concentrations is investigated. It is concluded that for a fixed number concentration of particles at the center of a cavity, the spatial distribution of particle concentration is of oscillating nature and has a global maximum.

Estimation of the ionic distribution in a reverse micelle: effects of ionic size

Article Abstract:

The influence of the presence of a soluble, nanosized particle in a reverse micelle on the dissociation of surfactant molecules is discussed. It is observed that the thermal Brownian motion of the particle in the aqueous core can affect the structure of a reverse micelle, the position of the particle may be shifted due to a change in the temperature.

Derivation of analytical expressions for the electrical potential distribution in lipid structures

Article Abstract:

The electrical potential inside a lipid structure, which is described by a modified Poisson-Boltzmann equation, is solved, taking into account the effect of ionic sizes. It is shown that if the linear size of a reversible micelle is fixed, the degree of dissociation of the surfactant layer follows the order planar > cylindrical > spherical.
