Wetting dynamics on lyophilic solid surfaces patterned by lyophobic islands
R. Tsekov, D. Borissov, S. I. Karakashev
A theory for wetting of structured solid surfaces is developed, based on the delta-comb periodic potential. It possesses two matching parameters: the effective line tension and the…
Effect of the adsorption component of the disjoining pressure on foam film drainage
S. I. Karakashev, A. V. Nguyen, R. Tsekov
The present work is trying to explain a discrepancy between experimental observations of the drainage of foam films from aqueous solutions of sodium dodecyl sulfate (SDS) and the t…
Bayesian approach to electron correlation in density functional theory
R. Tsekov, G. N. Vayssilov
In the present communication the Bayesian conditional probability approach is applied to the wave function of a many-electron system that results in appearance of a quantum vector…
On the rheology of a liquid-vapor interface
Roumen Tsekov, Boryan Radoev
The mass and momentum balances are theoretically studied in heterogeneous two-component systems. Following Gibbs the system is presented as two bulk and a single surface phases. Co…
Is Einstein's relation D = kTU always true?
Roumen Tsekov
The validity of Einstein's fluctuation-dissipation relation is discussed in respect to the type of relaxation in an isothermal system. The first model, presuming isothermic fluctua…
Dynamics and stability of dispersions of polyelectrolyte-filled multilayer microcapsules
Byoung-Suhk Kim, Vladimir Lobaskin, Olga I. Vinogradova
We report dynamic and coagulation properties of a dispersion of polyelectrolyte multilayer microcapsules filled with solutions of a strong polyelectrolyte. The capsule self-diffusi…
