Surfactants–molecules and particles that preferentially adsorb to fluid interfaces–play a
ubiquitous role in the fluids of industry, of nature and of life. Since most surfactants cannot be …

The effectiveness of water flooding oil recovery depends to an important extent on the
competitive wetting of oil and water on the solid rock matrix. Here, we use macroscopic …

Advanced water flooding processes through tailoring of injection water salinity and ionic
composition are becoming an attractive proposition for improved and enhanced oil recovery …

Understanding the adsorption dynamics of soft microgel particles is a key step in designing
such particles for potential applications as stimuli-responsive Pickering stabilizers for foams …

Most solid surfaces acquire a finite surface charge after exposure to aqueous environments
caused by desorption and/or adsorption of ionic species. The resulting electrostatic forces …

Oil/water interfaces are ubiquitous in nature. Opposing polarities at these interfaces attract
surface-active molecules, which can seed complex viscoelastic or even solid interfacial …

We studied the formation and stability of stearic acid (SA) based films on aqueous sub-
phases via Langmuir trough and imaging ellipsometry experiments. The aqueous phase …

We experimentally study the influence of inorganic salt ions on the wettability of originally oil-
wet rock surfaces, formed by adsorbing polar molecules via polar interactions. It is found that …

On the basis of dynamic interfacial tension measurements, Ca2+ has been shown
specifically to interact with naphthenic acid (NA) at the n-heptane/water interface, consistent …

We use contact angle goniometry, imaging ellipsometry, and atomic force microscopy to
study the stability and wettability of Langmuir–Blodgett (LB) monolayers of stearic acid on …
