“Studies of Asphaltene Adsorption and Its Remediation Using HPLC”

Fouling due to asphaltene adsorption or deposition onto sand during oil-sand extraction causes continuous problems for the petroleum industry as it lowers production rates and overall recovery. This study provides a quantitative characterization of the process using high performance liquid chromatography (HPLC). An asphaltene-simulating polymer dissolved in tetradecane is passed through a column packed with sand while the output composition, flow rate and pressure drop are monitored. Analysis based on the Ergun equation leads to the adsorption isotherm and adlayer thickness. Prior passivation of the silica surface with an appropriate surfactant is found to significantly mitigate the polymer adsorption.

“Facial Moisturizer in a New Product Format”

Facial moisturizers and other topical applications are currently delivered as thick liquids or gels. These have some drawbacks as they can run and drip, and sometimes have a poor “feel.” We seek to remedy these problems through the use of a new product format, viz., a dense, stable foam. The product is to be prepared in two main steps: 1) Preparation of an O/W emulsion consisting of silicone oil and an elastomer gel, and 2) Creation a foam from the above emulsion, using a commercial restaurant whipping device. By varying product formulation and preparation procedures, a product of superior “feel” and stability has been produced.

“Electric Charge Creation and Stabilization in Apolar Media: the Effect of Temperature”

Electric charges can be created and stabilized in media of very low dielectric constant using surfactant additives that create self-assembled structures called “reverse micelles,” consisting usually of ten to twenty monomers. At a “critical micelle concentration” (CMC) of surfactant, these structures form and provide a polar interior usually containing a few molecules of water. Electric charges may be housed in the interior of the reverse micelles. There are several important applications of charging in these media, including electrophoretic displays (e.g., the Amazon Kindle®) and a new electrostatic printing process (e.g., Hewlett-Packard’s Indigo®) Some of these processes operate at elevated temperatures, and the current research reveals that changing temperature has a significant impact on the charging process.

“The Rheology of Abrasive Slurries”

Dense aqueous slurries of abrasive particles are used for jet cutting, but their use presents problems, in particular the sedimentation of the particles and their jamming as they flow through the process lines. The current research seeks to modify the rheology of these slurries using appropriate additives to keep the particles in suspension, and to lubricate them as they flow through constrictions.
