Water is co-produced with crude oils, generally in the form of water-in-crude oil emulsions.
The oil and water phases need to be separated before export. Separation is performed in …

An active droplet system, programmed to repeatedly move autonomously at a specific
velocity in a well‐defined direction, is demonstrated. Coulombic energy is stored in …

Hypothesis: The droplet-medium interfaces of petroleum emulsions are often stabilized by
the indigenous surface-active compounds (eg., asphaltenes), causing undesired issues …

Assemblies of nanoparticles at liquid interfaces hold promise as dynamic “active” systems
when there are convenient methods to drive the system out of equilibrium via crowding. To …

Demulsifying highly stable W/O emulsions, composed of heavy oil and water, is crucial for
simplifying crude oil processing, reducing production costs, and mitigating environmental …

The performance of Carbon Nanotubes hybrid hydrogels for environmental remediation was
investigated using Methylene Blue (MB), Rhodamine B (RD), and Bengal Rose (BR) as …

Electrostatic demulsification is a promising technique to disrupt petroleum emulsions.
However, the presence of salts in the emulsion can influence the effectiveness of the electric …

We present a novel technique to measure the interfacial dilational rheology of a molecular
film adsorbed at a water–oil interface in a direct-current (dc) electric field. A film of a highly …

Electrostatic interactions play an important role in functional self-assembled structures of
both natural and synthetic origin. Such processes are complex and reflect the importance of …

Immiscible liquid-liquid dispersion is widely encountered in petroleum, chemical, and
pharmaceutical industries, where component and energy between two liquids are hard to …
