The application of asphalt materials in pavement engineering has been increasingly
widespread and sophisticated over the past several decades. Variations in the properties of …

Asphalthenes are typically defined as the fraction of petroleum insoluble in n-alkanes
(typically heptane, but also hexane or pentane) but soluble in toluene. This fraction causes …

As the precursor material inherently determines the fundamental structure of hard carbons, a
direct manipulation of precursors at the molecular level promises enhanced flexibility in …

We report classical atomistic molecular dynamics simulations of four structurally diverse
model asphaltenes, a model resin, and their respective mixtures in toluene or heptane under …

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 …

The adsorption and desorption of asphaltene on silica surface is highly dependent on the
heteroatoms present in its structure. Herein, some model asphaltene molecules with …

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

Asphaltene deposition is one of the challenging issues in petroleum production and
transportation. Chemical inhibitors are commonly employed to mitigate the asphaltene …

Heavy oil and bitumen drive the leading energy supply in Canada. Several techniques,
including in situ thermal methods and mining, have been applied to the recovery of these …

The oil production by the natural energy in oil reservoirs is decreasing gradually. Only 25–
30% of the world's reservoirs can be produced naturally, and different methods are …
