MEAM Seminar: “Designing Interfacial Phenomena for Water, Energy, and Sustainability”

February 7, 2023 at 10:00 AM - 11:30 AM

Solid/water interfacial phenomena are pervasive in both natural and built environments. Heat exchangers, membrane pores, and packed bed reactors are all examples of solid/water interfaces where interfacial phenomena and small-scale fluid physics can have outsized influences on process efficacy and sustainability. Even innocuous surfaces such as reactor walls are not inert and can actively interact with aqueous solutions and thereby create inefficiencies. Surface properties are crucial in controlling and reducing such inefficiencies. New tools and techniques in the fields of micro/nano-fabrication, thin film deposition, and soft matter physics have enabled unprecedented capability to manufacture engineered interfaces. By precisely designing the composition, chemistry, and microscopic geometry of interfaces, it is possible to go beyond simply selecting the best available material for a given application. Instead, we can specifically design surfaces and processes for fine-tuned control over interfacial phenomena to achieve drastic reduction, or even complete elimination, of inefficiencies. Here, three examples in which interfacial engineering can enable new paradigms for water, energy, and sustainability will be presented. I will show that composite liquid/solid surface can eliminate mineral fouling for improved material resilience, that nano-engineered materials can induce ejection of foulant crystals with potential application for heat transfer and waste brine management, and that multiphase microfluidics with controlled pore geometries can enable new separation processes.
