Abstract Changes of the refractive index for homologous series of hydrocarbons are usually
plotted versus the density. While there is a clear linear dependence for alkanes and alkenes …

The maximum capacitive energy stored in polymeric dielectric capacitors, which are
ubiquitous in high-power-density devices, is dictated by the dielectric breakdown strength of …

In this work, we present a series of correlations between physical and chemical properties of
asphaltenes based on extensive characterization of asphaltene solubility fractions from …

Abstract Changes in operating conditions such as pressure, temperature and composition of
the oil can trigger asphaltene deposition during oil recovery operations. In the present work …

The dielectric constant is used in aircraft for onboard fuel density and volume gauging,
which is essential for safety and efficiency. The goal of this paper is to report the effects of …

Asphaltene, resin, and maltene physical isolation procedures involving different alkane
precipitants and solvent/sample ratios were applied in this work to Athabasca bitumen …

Two methods of asphaltenes fractionation have been employed to facilitate the
characterization of their respective subfractions. The methods are based on step-wise …

Analysis of spatial gradients of the concentration of asphaltenes in reservoir crude oils has
become an important tool for oilfield reservoir characterization. Modeling these gradients …

In the present work, a series of asphaltene solubility fractions extracted from a heavy crude
oil have been analyzed using laser desorption ionization (LDI) and atmospheric pressure …

Solubility of all proposed molecular models of asphaltene in various solvents is studied
through molecular dynamics simulation to find the structural parameters which have a …
