    • Charge regulation of colloidal particles : theory and simulations 

      Bakhshandeh, Amin; Frydel, Derek; Diehl, Alexandre; Levin, Yan (2019) [Artículo de periódico]
      To explore charge regulation (CR) in physicochemical and biophysical systems, we present a model of colloidal particles with sticky adsorption sites which account for the formation of covalent bonds between the hydronium ...

    • Effects of the dielectric discontinuity on the counterion distribution in a colloidal suspension 

      Santos, Alexandre Pereira dos; Bakhshandeh, Amin; Levin, Yan (2011) [Artículo de periódico]
      We introduce a new method for simulating colloidal suspensions with spherical colloidal particles of dielectric constant different from the surrounding medium. The method uses an approximate calculation of the Green function ...

    • Interaction between random heterogeneously charged surfaces in an electrolyte solution 

      Bakhshandeh, Amin; Santos, Alexandre Pereira dos; Diehl, Alexandre; Levin, Yan (2015) [Artículo de periódico]
      We study, using Monte Carlo simulations, the interaction between infinite heterogeneously charged surfaces inside an electrolyte solution. The surfaces are overall neutral with quenched charged domains. An average over the ...

    • Isothermal adsorption of polyampholytes on charged nanopatterned surfaces 

      Bakhshandeh, Amin; Santos, Alexandre Pereira dos; Diehl, Alexandre; Levin, Yan (2019) [Artículo de periódico]
      We investigate the adsorption of neutral polyampholytes on charged nanopatterned surfaces. The surfaces have charged domains but are overall neutral. To perform efficient simulations, we use an approach which combines the ...

    • Weak and strong coupling theories for polarizable colloids and nanoparticles 

      Bakhshandeh, Amin; Santos, Alexandre Pereira dos; Levin, Yan (2011) [Artículo de periódico]
      A theory is presented which allows us to accurately calculate the density profile of monovalent and multivalent counterions in suspensions of polarizable colloids or nanoparticles. In the case of monovalent ions, we derive ...

    • Widom insertion method in simulations with Ewald summation 

      Bakhshandeh, Amin; Levin, Yan (2022) [Artículo de periódico]
      We discuss the application of the Widom insertion method for calculation of the chemical potential of individual ions in computer simulations with Ewald summation. Two approaches are considered. In the first approach, an ...
