Percolation connectivity in deposits obtained using competitive random sequential adsorption of binary disk mixtures
N. I. Lebovka, M. R. Petryk, N. V. Vygornitskii
Connectedness percolation phenomena in the two-dimensional (2D) packing of binary mixtures of disks with different diameters were studied numerically. The packings were produced us…

The paper deals with relationships between the individual transmembrane fluxes of binary electrolyte solution components and the experimentally measurable quantities describing rat…
Confinement effects on the random sequential adsorption packings of elongated particles in a slit
Nikolai I. Lebovka, Mykhailo O. Tatochenko, Nikolai V. Vygornitskii +1
The behavior of a system of two-dimensional elongated particles (discorectangles) packed into a slit between two parallel walls was analyzed using a simulation approach. The packin…
Random sequential adsorption of partially ordered discorectangles onto a continuous plane
Nikolai I. Lebovka, Nikolai V. Vygornitskii, Yuri Yu. Tarasevich
Computer simulation was used to study the random sequential adsorption of identical discorectangles onto a continuous plane . The problem was analyzed for a wide range of discorect…
Vertical drying of a suspension of sticks: Monte Carlo simulation for continuous two-dimensional problem
Nikolai I. Lebovka, Yuri Yu. Tarasevich, Nikolai V. Vygornitskii
The vertical drying of a two dimensional colloidal film containing zero-thickness sticks (lines) was studied by means of kinetic Monte Carlo (MC) simulations. The continuous two-di…
Ultrafiltration of charge-stabilized dispersions at low salinity
Rafael Roa, Daniel Menne, Jonas Riest +5
We present a comprehensive study of cross-flow ultrafiltration (UF) of charge-stabilized suspensions, under low-salinity conditions of electrostatically strongly repelling colloida…
Sedimentation stability and aging of aqueous dispersions of Laponite in the presence of cetyltrimethylammonium bromide
V. Savenko, L. Bulavin, M. Rawiso +3
This work discusses the sedimentation stability and aging of aqueous suspension of Laponite in the presence of cetyltrimethylammonium bromide (CTAB). The concentration of Laponite…
Low temperature phase transformations in 4-cyano-4'-pentylbiphenyl (5CB) filled by multiwalled carbon nanotubes
N. Lebovka, V. Melnyk, Ye. Mamunya +3
The effects of multiwalled carbon nanotubes (NTs) on low-temperature phase transformations in 5CB were studied by means of differential scanning calorimetry (DSC), low-temperature…
