Electro-osmosis (EO) is a powerful tool to manipulate liquids in micro and nanofluidic systems. While EO has been studied extensively at liquid-solid interfaces, the case of liquid-vapor interfaces, found e.g. in foam films and bubbles, remains to be explored. Here we perform molecular dynamics (MD) simulations of EO in a film of aqueous electrolyte covered with fluid layers of ionic surfactants and surrounded by gas. Following the experimental procedure, we compute the zeta potential from the… 
Electroosmosis near surfactant laden liquid-air interfaces.
Generation of an electroosmostic flow near a liquid-gas interface covered with ionic surfactants is experimentally investigated and shows that under an electrical forcing, although a liquid flow is generated below the free surface, the surfactant remain immobile.
Electrokinetic transport of a non-conducting liquid droplet in a polyelectrolyte medium
A numerical study on the electrophoresis of a liquid droplet embedded in a polyelectrolyte hydrogel medium is made by considering the full set of governing equations based on the conservation
Nanomolar surface-active charged impurities account for the zeta potential of hydrophobic surfaces.
It is shown that the interfacial adsorption and repulsion of small inorganic ions such as H3O+, OH-, HCO3-, and CO32- cannot account for the ζ potential observed in experiments because the surface affinities of these ions are too small.

Measuring surface charge: Why experimental characterization and molecular modeling should be coupled


Scrutinizing Electro-Osmosis and Surface Conductivity with Molecular Dynamics
We present a simulation and modeling study of electro-osmotic flow of an aqueous cesium chloride solution confined in a charged amorphous silica slot. Contrasting traditional models of the electric
Anomalous ζ potential in foam films.
It is found that the ζ potential, quantifying the amplitude of electrokinetic effects, depends on the surfactant coverage in an unexpected way, and does not vanish in the limit of low coverage but instead approaches a finite value.
How Electrostatics Influences Hydrodynamic Boundary Conditions: Poiseuille and Electro-osmostic Flows in Clay Nanopores.
We report on a molecular simulation study of the origin of nonslip or slip hydrodynamic boundary conditions in clay nanopores, focusing on the role of electrostatics. We simulate hydrodynamic and
Macro- versus microscopic view on the electrokinetics of a water-membrane interface.
This work considers a POPC bilayer in an aqueous solution with 500 mM NaCl, using molecular dynamics simulations, and finds that POPC shows positive electrophoretic mobility due to adsorption of sodium ions at the lipid headgroups.
Why are hydrophobic/water interfaces negatively charged?
The basic assumption of all previous experimental and theoretical studies has been that these systems have “pristine” oil/water interfaces, that is, oil molecules in contact with water molecules, although the possibility of contamination by anionic, surface-active impurities has been mentioned.
Aqueous electrolytes near hydrophobic surfaces: dynamic effects of ion specificity and hydrodynamic slip.
We demonstrate, using molecular-dynamics computer simulations, the strong influence of surface wettability on the equilibrium structure of the electrical double layer at solid interfaces and on

We study the influence of UV light on the drainage flows of foams and thin-liquid films stabilized by photoswitchable azobenzene surfactants, whose shape and hydrophobicity can be modified using UV
Beyond the continuum: how molecular solvent structure affects electrostatics and hydrodynamics at solid-electrolyte interfaces.
The two-scale approach employed here-MD simulations and continuum theory-constitutes a successful modeling scheme, providing basic insight into the molecular origins of the static and kinetic properties of charged surfaces, and allowing quantitative modeling at low computational cost.
Amplification of electro-osmotic flows by wall slippage: direct measurements on OTS-surfaces.
It is shown that on smooth hydrophilic silica these quantities are similar, whereas on OTS-silanized hydrophobic surfaces the zeta potential is significantly higher, leading to an enhanced electro-osmotic velocity, which is consistent with an interfacial water slippage on the silanized surface.
