Colloidal charge renormalization in suspensions containing multivalent electrolyte
(2010) [Artigo de periódico]A theory is proposed which allows us to self-consistently calculate the effective colloidal charge and the counterion and coion density profiles in suspensions containing both multivalent and monovalent electrolytes. The ... -
Colloidal charge reversal : dependence on the ionic size and the electrolyte concentration
(2008) [Artigo de periódico]Extensive Monte Carlo simulations and scaling arguments are used to study the colloidal charge reversal. The critical colloidal surface charge density σc at which the reversal first appears is found to depend strongly on ... -
Electrostatic correlations in colloidal suspensions : density profiles and effective charges beyond the Poisson–Boltzmann theory
(2009) [Artigo de periódico]A theory is proposed which allows us to calculate the distribution of the multivalent counterions around a colloidal particle using the cell model. The results are compared with the Monte Carlo simulations and are found ... -
"Phantom ion effect" and the contact potencial of the water-vapor interface
(2008) [Artigo de periódico]The contact (junction) potential between water-vapor and water-oil interfaces is studied theoretically. Unlike the previous studies, we show that ionic contribution to the contact potential vanishes when the concentration ... -
The renormalized Jellium model of colloidal suspensions with multivalent counterions
(2010) [Artigo de periódico]An extension of the renormalized Jellium model which allows to study colloidal suspensions containing trivalent counterions is proposed. The theory is based on a modified Poisson–Boltzmann equation which incorporates the ...
