Atomic force microscopy (AFM) is frequently used to elucidate complex interactions in emulsion systems. However, comparing results obtained with “model” planar surfaces to curved emulsion interfaces often proves unreliable, because droplet curvat

Iron doped Gallium Nitride is a promising candidate for high power laser operation at 1µm. We report novel spectroscopic characterization on samples with iron doping densities ranging from 1.0 x 1016 ions/cm3 to 9.0 x 1019 ions/cm3.

Molecular dynamics (MD) simulations were used to study the nanoaggregation of model asphaltene molecules in binary mixtures of toluene and water. Four types of model asphaltenes were studied: continental (C), Violanthrone-79 (VO-79), anionic continen

A photometer was utilized to measure the intensity of scattered light in toluene / heptane / asphaltenes mixtures. On the scattering-intensity versus heptane-to-toluene ratio functions, two linear regions can be observed. The intersection of these re

Monolayer characteristics of subfractions and unfractionated whole asphaltenes from Athabasca oil sands bitumen were studied at heptane-water interface. The transferred Langmuir-Blodgett films of asphaltenes were characterised with atomic force micro

A multilayer asphaltene film of about ∼3−4 layers thick was prepared by spreading an excess amount of asphaltene on a water subphase. Once toluene was placed on top of the multilayer film, some of the asphaltenes migrated to the bulk toluene topp

This work aims to identify the nature of the charge carriers in Athabasca bitumen to better understand the mechanisms of emulsion stabilization and electrically induced separations. A quartz crystal microbalance (QCM) with nanogram sensitivity is use

Asphaltene films at a toluene/water interface were characterized using a Langmuir interfacial trough. An asphaltene monolayer was determined to remain at the toluene/water interface, and asphaltenes do not migrate from the monolayer to the bulk tolue

The objective of this study was to obtain estimates for the refractive indices of bitumen, maltenes, and asphaltenes. Refractive index measurements performed on various bitumen–solvent mixtures were analyzed using a mixing model that related the re

In a ternary phase diagram of sodium naphthenates (SN), toluene, and water the following phases can be formed at 25°C: normal micellar solution; inverse micellar solution; lamellar liquid crystal; microemulsion; and turbid birefringent gel phase. Th
