Published in 2017 at "Canadian Journal of Chemical Engineering"

DOI: 10.1002/cjce.22892

Abstract: Tiny water droplets in oil emulsions are commonly encountered in the petroleum industry. The high viscosity of the oil hampers the physical separation of the water droplets from the oil.[1] Phase inversion could be a… read more here.

Published in 2017 at "Colloids and Surfaces A: Physicochemical and Engineering Aspects"

DOI: 10.1016/j.colsurfa.2017.03.029

Abstract: Abstract Relatively monodisperse spherical poly(styrene-co-acrylonitrile) (SAN) particles may be prepared using phase inversion from water-in-oil (W/O) to oil-in-water (O/W) emulsions containing water-soluble methyl ethyl ketone (MEK) as the oil phase. In this study, we investigate… read more here.
