Journal ArticleDOI
Microscale Heat Transfer Transduced by Surface Plasmon Resonant Gold Nanoparticles.
TL;DR: Temperature in =10-microliter aqueous suspensions of 20-nanometer gold particles irradiated by a continuous wave Ar+ ion laser at 514 nm increased to a maximum equilibrium value in proportion to incident laser power and to nanoparticle content at low concentration.
Journal ArticleDOI
A Fundamental Study of Asphaltene Deposition

TL;DR: In this article, asphaltene deposits were generated in metal capillaries by heptane addition to crude oils, and it was found that deposition is caused by submicrometer aggregates.
Journal ArticleDOI
The Fractal Aggregation of Asphaltenes
TL;DR: Time-resolved small-angle neutron scattering results that were used to investigate asphaltene structure and stability with and without a precipitant added in both crude oil and model oil found that both soluble and insoluble asphaltones form fractal clusters in crude oil.
Journal ArticleDOI
Modeling the Aggregation of Asphaltene Nanoaggregates in Crude Oil−Precipitant Systems
TL;DR: In this article, a generalized geometric population balance model for simulating the growth of asphaltene aggregates from the nanometer scale to micrometer-sized particles is presented.
Journal ArticleDOI
Multiscale scattering investigations of asphaltene cluster breakup, nanoaggregate dissociation, and molecular ordering.
TL;DR: Significant differences in the WAXS peak positions and shapes between aromatic and nonaromatic solvents suggests that there may be large differences between the solvation shell or conformation of the asphaltene alkyl shell depending on the surrounding liquid environment.
