Asphaltenic aggregates are polydisperse oblate cylinders

JOURNAL OF COLLOID AND INTERFACE SCIENCE, 288(2), 325–334.

By: K. Gawrys n & P. Kilpatrick n

author keywords: asphaltenes; small-angle neutron scattering; polydispersity
TL;DR: Results indicate that the polydisperse radius oblate cylinder model best approximates the shape of asphaltene scattering spectra, and agreement of the model fit parameters (I(0) and R(G)) with those obtained from Guinier analyses suggests that such a form factor model is physically reasonable.

Aggregation and solubility behavior of asphaltenes and their subfractions

JOURNAL OF COLLOID AND INTERFACE SCIENCE, 267(1), 178–193.

By: P. Spiecker n, K. Gawrys n & P. Kilpatrick n

TL;DR: Asphaltenes from four different crude oils were fractionated in mixtures of heptane and toluene and analyzed chemically, by vapor pressure osmometry (VPO), and by small angle neutron scattering (SANS). (via Semantic Scholar)
