Emulsion Formation using corona discharge and electrohydrodynamic pumping

Project ID: D2020-22 Background Making water-in-oil emulsions often requires high pressure, ultrasonication, or sensitive inversion techniques that may still only result in a semi-stable colloid. In addition to emulsion shelf life, these techniques have drawbacks, such as having high-energy consumption and narrow/sensitive production parameters, needing...

Selective recovery of polypropylene (and polyethylene) from mixed plastic wastes

Project ID: D2021-43 Background Polypropylene (PP) is a thermoplastic polymer used in packaging materials, consumer goods, automotive components, and medical devices. It is difficult to recover PP from mixed plastic waste streams; PP has a similar density to polyethylene (PE) and cannot be selectively separated from PE via the sink-float methods...
