Charge separation at liquid interfaces
Arghya Majee, Christoph A. Weber, Frank Jülicher
We present a theory for phase-separated liquid coacervates with salt, taking into account spatial heterogeneities and interfacial profiles. We find that charged layers of alternati…
Electrostatic interactions between charge regulated spherical macroions
Hu Ruixuan, Arghya Majee, Jure Dobnikar +1
We study the interaction between two charge regulating spherical macroions with dielectric interior and dissociable surface groups immersed in a monovalent electrolyte solution. Th…
Curvature effects in interfacial acidity of amphiphilic vesicles
Petch Khunpetch, Arghya Majee, Hu Ruixuan +1
We analyze the changes in the vicinal acidity (pH) at a spherical amphiphilic membrane. The membrane is assumed to contain solvent accessible, embedded, dissociable, charge regulat…
Curvature effects in charge-regulated lipid bilayers
Petch Khunpetch, Arghya Majee, Rudolf Podgornik
We formulate a theory of electrostatic interactions in lipid bilayer membranes where both monolayer leaflets contain dissociable moieties that are subject to charge regulation. We…
Electroviscous drag on squeezing motion in sphere-plane geometry
Marcela Rodriguez Matus, Zaicheng Zhang, Zouhir Benrahla +3
Theoretically and experimentally, we study electroviscous phenomena resulting from charge-flow coupling in a nanoscale capillary. Our theoretical approach relies on Poisson-Boltzma…
Charge symmetry broken complex coacervation
Arghya Majee, Markus Bier, Ralf Blossey +1
Liquid-liquid phase separation has emerged as one of the important paradigms in the chemical physics as well as biophysics of charged macromolecular systems. We elucidate an equili…
Electrostatic pair-interaction of nearby metal or metal-coated colloids at fluid interfaces
Rick Bebon, Arghya Majee
In this paper, we theoretically study the electrostatic interaction between a pair of identical colloids with constant surface potentials sitting in close vicinity of each other at…
Charge regulation radically modifies electrostatics in membrane stacks
Arghya Majee, Markus Bier, Ralf Blossey +1
Motivated by biological membrane-containing organelles in plants and photosynthetic bacteria, we study charge regulation in a model membrane stack. Considering (de)protonation as t…
Electrostatic interaction between dissimilar colloids at fluid interfaces
Arghya Majee, Timo Schmetzer, Markus Bier
The electrostatic interaction between two non-identical, moderately charged colloids situated in close proximity of each other at a fluid interface is studied. By resorting to a we…
Spontaneous symmetry breaking of charge-regulated surfaces
Arghya Majee, Markus Bier, Rudolf Podgornik
The interaction between two chemically identical charge-regulated surfaces is studied using the classical density functional theory. In contrast to common expectations and assumpti…
Rotational motion of dimers of Janus particles
Arghya Majee
We theoretically study the motion of a rigid dimer of self-propelling Janus particles. In a simple kinetic approach without hydrodynamic interactions, the dimer moves on a helical…
Nanoscale Seebeck effect at hot metal nanostructures
Aboubakry Ly, Arghya Majee, Alois Würger
We theoretically study the electrolyte Seebeck effect in the vicinity of a heated metal nanostructure, such as the cap of an active Janus colloid in an electrolyte, or gold- coated…
Poisson-Boltzmann study of the effective electrostatic interaction between colloids at an electrolyte interface
Arghya Majee, Markus Bier, S. Dietrich
The effective electrostatic interaction between a pair of colloids, both of them located close to each other at an electrolyte interface, is studied by employing the full, nonlinea…
Electrostatic interaction between colloidal particles trapped at an electrolyte interface
Arghya Majee, Markus Bier, S. Dietrich
The electrostatic interaction between colloidal particles trapped at the interface between two immiscible electrolyte solutions is studied in the limit of small inter-particle dist…
Collective thermoelectrophoresis of charged colloids
Arghya Majee, Alois Würger
Thermally driven colloidal transport is, to a large extent, due to the thermoelectric or Seebeck effect of the charged solution.We show that, contrary to the generally adopted sing…
Thermocharge of a hot spot in an electrolyte solution

We discuss the thermoelectric properties of a locally heated micron-size volume in an electrolyte solution. We find that such a hot spot carries a net charge Q which, for an excess…
Charging of Heated Colloidal Particles Using the Electrolyte Seebeck Effect
