Profiling Alkyl Phosphates in Petroleum Samples by Comprehensive Two-dimensional Gas Chromatography with Nitrogen-phosphorus Detection (GC×GC-NPD)
DownloadFall 2014
The profiling of alkyl phosphates in petroleum samples is of particular interest to refineries that process conventional crude oil derived from the Western Canadian Sedimentary Basin and other similar geologies. This is due to alkyl phosphate-based additives used during crude oil recovery...

Liquid crystalline domains were observed in fractions of heavy petroleum. Through a combination of polarized light microscopy and Photoacoustic Infrared Spectroscopy, liquid crystals were shown to form on the exterior surface of their parent materials. Analysis of materials using Differential...

We numerically study different forms of nanoscale gaseous domains on a model for rough surfaces. Our calculations based on the constrained lattice density functional theory show that the inter-connectivity of pores surrounded by neighboring nanoposts, which model the surface roughness, leads to...

Sowa, Barbara, Zhang, Xuehua, Kozielski, Karen A., Dunstan, Dave E., Hartley, Patrick G., Maeda, Nobuo
We recently reported the development of a high pressure electrical conductivity probe (HP-ECP) for experimental studies of formation of gas hydrates from electrolytes. The onset of the formation of methane-propane mixed gas hydrate from salt solutions was marked by a temporary upward spike in the...
