Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all
aspects of petroleum utilization, including reservoir characterization, production …

We review the existing literature on asphaltenes at various types of interfaces: oil–water, air–
water, gas–oil and solid–liquid, with more emphasis on the oil–water interfaces. We address …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

In an earlier study, oil–water interfacial tension was measured by the pendant drop
technique for a range of oil-phase asphaltene concentrations and viscosities. The interfacial …

Heavy oil, commonly defined by high density, viscosity, and heavy components
distinguishing it from light oil, has a peculiar nature with respect to emulsification. In this …

Asphaltene finds a distinguished position in current research on liquid and solid
hydrocarbon fuels due to its self-aggregating nature. The presence of asphaltene in crude …

It is well known that asphaltene molecules play a significant role in stabilizing emulsions of
water in crude oil or diluted bitumen solutions. Molecular dynamics simulations were …

Carboxyl asphaltene is commonly discussed in the petroleum industry. In most conditions,
electroneutral carboxyl asphaltene molecules can be deprotonated to become carboxylate …

In this work, pendant drop techniques and molecular dynamics (MD) simulations were
employed to investigate the effect of asphaltene concentrations on the interfacial tension …

The aggregation behaviors of asphalt on the hydrate surface with different surfactant
coverages were studied by molecular simulations. The molecular polarity index of asphalt …
