Nanoengineered Materials and Thermal Engineering for Advanced Energy and Water Technologies
Abstract: Nanoengineered materials have exciting, untapped potential to improve energy and water technologies. In this talk, I provide a few examples of how we leverage nanoscale manipulation capabilities to develop advanced thermal management, solar thermal energy conversion and water harvesting devices. First, I discuss our recent work that harnesses novel surface designs to control and manipulate wettability and liquid-vapor phase-change processes. We demonstrated high flux evaporation from ultra-thin nanoporous membranes and robust nanostructured surfaces that can repel liquids during condensation. Next, I discuss how nanoengineered materials can also be used to increase the efficiency of solar thermal devices. Specifically, I share our work on optically transparent thermally insulating aerogel solar receivers for energy conversion and medical sterilization. Finally, I present a water harvesting device that leverages the unique properties of metal organic frameworks and other adsorbents along with novel device architectures to address water scarcity challenges in arid climates.
