A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishing
DownloadFall 2011
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...

Bhattacharya, Sujit, Arora, Nitin, Ng, Samson, Chong, Jeng Y., Kresta, Suzanne M., Machado, Marcio B.
Mixing conditions were explored as a possible avenue for improvement of demulsifier performance in solvent diluted bitumen de-watering process. The effects of demulsifier bulk concentration, demulsifier injection concentration and mixing energy on water and solids removal from the oil phase were...

Fall 2013
The impact of mixing on water removal from diluted bitumen and bitumen froth is studied, with the goal of maximizing demulsifier performance. The relative effects of bulk concentration, mixing intensity, mixing time and injection concentration on the demulsifier performance are evaluated. A...

Fall 2011
The impact of mixing on diluted bitumen de-watering is studied in two stages using a fractional factorial design of experiments. The first stage evaluates the relative effects of bulk demulsifier dosage, local maximum energy dissipation, and mixing time. The second stage of experiments evaluates...
